Frequently Asked Questions
Everything you need to know about using Underpriced AI to identify, price, and sell your items.
Getting Started
What is Underpriced AI?
Underpriced AI is an AI-powered tool that helps resellers identify items, get instant valuations based on real market data, and create optimized listings for eBay, Poshmark, Mercari, and other marketplaces. Snap a photo and get pricing, comparable sales, and a ready-to-publish listing in seconds.
How do I scan an item?
Take a photo with your phone camera or upload an existing image. Our AI identifies the item, searches real-time sold data across eBay, Poshmark, Mercari, and other platforms, and returns a detailed valuation with price range, comparable sales, and a listing-ready title and description.
Do I need to connect or set up my camera?
No - there's nothing to pair or connect. On the scan screen, tap "Take Photo" and it uses your phone or computer's built-in camera right in the app. The first time, your browser or phone will ask permission to use the camera - tap Allow. If the camera doesn't open or you see a black screen, that's almost always a blocked permission: re-enable camera access for our site in your browser or phone settings, or just tap "Upload" instead to pick a photo you already took. The iOS and Android apps give the smoothest camera experience.
Can I add more than one photo of an item?
Yes — and you should when it helps. A single scan accepts up to 12 photos of the SAME item (for example the front, the back, a label, or a maker's mark). It still counts as just one scan no matter how many photos you add, and the extra angles make identification and pricing noticeably more accurate. So to capture the front and back of something, add both photos to one scan rather than scanning twice.
What should I photograph when scanning clothing items?
For clothing, take a clear photo of the item laid flat or on a hanger in good light. For best accuracy, also include the brand tag and the size/care label. These help us identify the exact item and match it to the right sold comps. You can add up to 12 photos to one scan (for example the garment, the brand tag, and the size tag) and it still counts as a single scan. The first three are what the AI reads; the rest are saved to the item and go onto your listing.
Do I need to download an app?
Underpriced AI works in your browser on any device - no download required. We also offer an iOS app on the App Store, an Android app on Google Play, and Chrome and Firefox browser extensions for scanning items while browsing online listings.
Is there a free scan or free trial?
Your first scan is free - no credit card required, and it is the full result: the AI identification, the exact price, the verified sold comps (with clickable links), and save-to-inventory. Nothing is held back. After that, pick a plan (starting at $5/month for 30 scans) or a pay-as-you-go credit pack (from $3 for 5 scans). Both include every feature - pricing, one-click cross-listing, inventory, and profit tracking. Sellers can also earn free scans instead of paying, once each: save your first find (+2), connect your eBay account (+5), publish your first listing (+5), and mark your first sale (+5). These bonuses go to free and pay-as-you-go accounts; plan subscribers scan against their monthly allowance.
Can I scan a barcode instead of taking a photo?
Yes. On the scan screen, choose the barcode option to scan a book's ISBN or a CD/vinyl UPC with your camera. We look the title up automatically (Google Books for books, Discogs for music) and then price it from real sold listings, exactly like a photo scan. For everything else - clothing, collectibles, electronics, housewares - a clear photo works best.
Can I scan multiple items at once?
Yes - use Batch Scan to do up to 10 different items at once (one photo each). It's built for clearing a pile fast: add up to 10 photos and we identify and price each item separately. Each item counts as its own scan toward your limit. (This is different from adding several photos of the SAME item to one scan, which still counts as a single scan - see above.)
How do I move a scanned item into my inventory?
You usually don't have to - when you scan an item on a paid scan, it's saved to your inventory automatically, so there's nothing to move. To find your scanned items, open your Inventory (the Items list). If a specific scan isn't there (for example a free preview scan, or one you discarded), open it from Scan History and tap Save to inventory. If by 'dead pile' you mean items you've saved but haven't sold yet, those are already in your inventory - the next step is to list them, either by publishing to a connected eBay account or by cross-listing to Poshmark, Mercari, and others with our browser extension.
How do I get started?
Sign up and your first scan is free - no credit card, and it shows everything: the item ID, the exact price, and the real sold comps behind it. Keep going with any plan or a $3 five-scan pack. Every plan includes every feature - pricing, one-click cross-listing, inventory, and profit tracking.
Pricing & Accuracy
How accurate is the AI pricing?
Read the range, not the number in the middle. Here is the honest reason. We measured how far apart genuinely identical items sell for, using comps an AI judged to be the same item in the same condition: the middle half of them span about 38% of their own median. The same object, different buyers, different days. So no tool, ours included, can tell you what YOUR item will fetch to the dollar, and any tool that shows a bare confident number is hiding that from you. What we do instead is set the range from that measured spread, so it contains the actual sale price about eight times in ten, and re-check it every week against sales we did not price. Every scan, the free one included, lists the comparable sold listings behind it with clickable links, plus a confidence indicator, so you can check our work in one tap. That is enough to answer the question you are actually asking in the aisle, which is whether the item is worth more than the price on the tag, not whether it is worth $92 or $105. The point estimate is a starting position. Accuracy depends on photo quality and how common the item is; add a second angle or a maker's mark for rare pieces, and cross-check the comps for anything high-value.
What happens if a pricing source is down or has never seen my item?
The scan moves down a ladder instead of giving up. We call a specialist sold-price API first. If it comes back empty we fail over to a second, independent vendor that is better at obscure items and covers markets outside the US. If the item was described too specifically to match anything, we retry with just the words that matter, which is the single biggest cause of an empty result. After that we fall back to scraping eBay sold listings ourselves, and finally to our own archive of over a million recorded sales, so an outage still returns a real comparable sale rather than a guess. If every source genuinely comes up empty we say so and label the estimate as AI-only, rather than pretending a number is backed by sales that do not exist.
Where does the pricing data come from?
From real sold prices, meaning what items actually sold for rather than what someone is currently asking, drawn from whichever source is best for the item. A specialist sold-price API is the first call, with an independent second vendor behind it that is better at obscure pieces and covers markets outside the US, our own live read of eBay sold listings behind that, and our archive of over a million recorded sales as the floor. Category specialists are added where they genuinely beat the general sources, and we retire them when they stop earning their place, so the exact list changes over time. We also check active listings to gauge current supply and saturation. Because it is a ladder rather than one fragile source, your pricing keeps working when any single site goes dark.
How is this different from checking eBay sold listings manually?
Manual research takes 5-10 minutes per item and stops at a number. Underpriced AI does the research from one photo, across eBay, Poshmark and Mercari plus whichever category specialists currently beat those for the item, and shows you the sold listings so you can check it. Then it does the part manual research never does: it writes the title, description and item specifics, publishes to eBay in one tap, cross-lists to six more marketplaces, and tracks the item until it sells. Worth it? Now sell it.
Can the AI identify any item?
The AI works best with branded items, electronics, collectibles, vintage goods, clothing, and common household items. Very obscure, handmade, or one-of-a-kind items may get a more general identification. Clear, well-lit photos - and adding multiple angles to one scan - dramatically improve accuracy.
What does the confidence score on my results mean?
Every scan shows a confidence score so you know how much to trust the estimate. Green (80%+) means we found solid, consistent sold data for a clearly identified item. Amber (60-79%) means the data is thinner or the item was harder to pin down. Red (under 60%) means treat it as a rough ballpark and double-check against the comparable sales we list. It's there so a confident-looking number never misleads you.
Why do you show 'sold' and 'asking' prices separately?
Because they're very different numbers. 'Recently sold' is what buyers actually paid - that's what your estimate is built on. 'Currently listed' is what other sellers are asking, which is often higher than items really sell for. We show both so you can see the gap, and when listings are asking noticeably more than things sell for, we flag it right on the result. Your suggested price follows real sales, not wishful asking prices.
Can I re-check an item's price later?
Yes, and it's free. On your Scans list, use 'Re-price' to re-run the latest market data on a past scan - handy when you're about to list something you scanned a while ago. It doesn't use a scan credit. You can re-price each item once every few hours.
Can I correct what the AI identified?
Yes. Open the item from the Items page and edit the title, brand, condition, and description fields directly - just type into the form fields. Those details flow into the listing we generate, so your title and description come out more accurate. To re-run the price using your corrections, tap 'Re-analyze' (the button says 'Use 1 Scan & Re-analyze' - it costs 1 scan credit because we re-run the AI with your edits). Notes typed into the description on their own don't automatically re-price the item; Re-analyze is what flips the valuation to reflect your edits.
Does the AI learn from my corrections?
Your inputs shape your own results - details you add, like exact dimensions or condition, are used to identify and price that item more precisely, and your saved corrections improve the listings we generate for you. What we don't do is quietly retrain a global model on your data in the background. If you spot an identification that's consistently off, tell us - that feedback is how we improve the system deliberately.
My price shows the wrong currency or country's marketplace (e.g. USD / ebay.com when I'm not in the US). How do I change it?
The currency and marketplace your prices use come from the Country set on your account, not from your phone or browser. Change it in Settings: open Settings, find the Country field near the top of your profile, pick your country, and save. That switches your prices to the matching eBay marketplace, currency, and shipping defaults (for example, changing to the UK moves you to eBay UK in GBP). If your account Country and your actual location don't match, Settings also shows a small prompt offering to update it for you. Supported countries include the US, UK, Canada, Australia, Germany, France, Italy, Spain, Netherlands, Belgium, and Mexico; if yours isn't listed, prices default to the US marketplace in USD.
Plans & Billing
What plans are available?
We offer six paid plans: Starter ($5/month, 30 scans), Pro ($12/month, 75 scans), Pro Plus ($24/month, 160 scans with inventory tools and the analytics dashboard), Business ($59/month, 425 scans), Power ($99/month, 750 scans), and Scale ($199/month, 1,800 scans included then 12 cents per scan after, so you never hit a wall) for full-time sellers. Annual billing saves 20%, and credit packs (1 to 250 scans) cover pay-as-you-go. Every scan runs on Claude Opus 4.8, one of Anthropic's most capable vision models. All plans include AI identification, real-time valuations, listing generation, and eBay integration.
What counts as a scan?
Each time you analyze an item - whether by taking a new photo, uploading an image, or re-analyzing a saved item - it counts as one scan toward your monthly limit. Adding multiple photos of the same item to a single scan still counts as just one scan, however many you add. Viewing previously saved scan results does not use a scan.
Does deleting a scanned item or its photos refund the scan credit it used?
No. Scans are counted at the moment the photo is analyzed, not by whether you keep the item afterward. Deleting a scan, an item, or any of its photos does not add a scan back to your monthly allowance or credit balance. If you accidentally created duplicate scans of the same item, you can still delete the extras to tidy up your inventory. It just will not change your scan count.
Can I change or cancel my plan?
Yes, and it's self-serve — go to Settings → Subscription Plans (underpricedai.com/settings). You can upgrade (with prorated credit for the unused portion of your current cycle), downgrade, pause, or cancel yourself in a couple of taps. If you cancel, it stops the renewal and you keep access through the end of your current billing period. Your saved scans and data are preserved either way.
What's your refund policy?
Your first scan is free so you can try Underpriced AI before paying. Because of that, monthly plans and scan credit packs are non-refundable - but you can change or cancel your plan anytime yourself in Settings → Subscription Plans (underpricedai.com/settings), and cancelling keeps full access through the end of the period you've paid for, with your scans and history preserved. Annual plans have a 30-day money-back guarantee: cancel within 30 days of buying and the whole charge is refunded. After that, cancelling stops the next renewal and you keep full access to the end of the year you paid for, with no partial refund (annual plans bought before September 9, 2026 keep their original unused-full-months refund on request). Not logged in? Use the Cancel Subscription page at underpricedai.com/cancel-subscription for a one-click cancel link, no sign-in needed. For a charge you don't recognize, contact us at underpricedai.com/contact with the email you signed up with.
I accidentally upgraded my plan by mistake - can I get a refund or reversal?
An in-app upgrade takes effect immediately and charges a prorated amount for the rest of your billing cycle, so an accidental tap can result in a charge. Plans are non-refundable. To stop any further charges, downgrade or cancel yourself in Settings → Subscription Plans (underpricedai.com/settings) - you keep access through the end of the period you've paid for. If you see a charge you don't recognize, contact us at underpricedai.com/contact with the email you signed up with and we'll look into it.
I'm not logged in and want to cancel - what do I do?
You don't need to log in. To cancel, use the Cancel Subscription page at underpricedai.com/cancel-subscription - enter the email on your subscription and we email you a one-click cancellation link, no sign-in required. It stops the renewal and you keep access through the end of the period you've paid for. Monthly plans and packs are non-refundable. Annual plans have a 30-day money-back guarantee: cancel within 30 days of buying and the whole charge is refunded; after that, cancelling stops the next renewal and you keep access to the end of the year you paid for, with no partial refund (annual plans bought before September 9, 2026 keep their original unused-full-months refund on request). For an annual refund, any other support, or a charge you don't recognize, ask the assistant at underpricedai.com/contact (say you need a person and leave the email you signed up with in the box that appears) or email support@underpricedai.com with that email.
What happens when I run out of scans?
When you reach your monthly scan limit, you can purchase additional scan credit packs or upgrade to a higher plan. Credit packs never expire and carry over month to month.
How do I check how many scans I have left?
Go to Settings and open the Subscription section. It shows your total scans available - your monthly plan allotment plus any credit-pack scans (which never expire and carry over month to month). That's the live count for your account.
How much do scan credit packs cost?
Credit packs are one-time purchases with no subscription required: 5 scans for $3, 15 scans for $7, 30 scans for $12, 50 scans for $18, 100 scans for $32, and 250 scans for $70. Bigger packs cost less per scan (from 80 cents down to about 36 cents each), and credits never expire - they carry over month to month. If you scan regularly, a subscription is the better per-scan deal; packs are built for occasional use or topping up when you hit your plan's limit.
I bought scan credits through an AI assistant (ChatGPT, Perplexity, Claude). Where are they?
Credit packs bought through an AI assistant are delivered by Stripe to the Underpriced AI account that owns the email you used at checkout. If you already had an account under that email, the credits are on it now (Settings shows your total). If you did not, we created one for you and emailed a welcome message plus a set-password link to that address, so sign in with that email. Used a different email at checkout than the one you sign in with? Contact us at underpricedai.com/contact with both addresses and the Stripe receipt and we will move the credits. Subscriptions cannot be started through an assistant; those begin at underpricedai.com/pricing.
Do you have a referral program?
Yes. Grab your referral link from Settings and share it. Your friend gets 25 bonus scans the moment they sign up, and you get 25 bonus scans when they subscribe or buy a credit pack. There's no limit on how many friends you can refer.
Why am I asked to verify my phone number by text at checkout?
That prompt comes from Stripe Link, our payment processor, not from Underpriced AI. Stripe offers to save your card by verifying your phone via text so future checkouts are faster. It is completely optional and skippable - just enter your card details directly to finish. We never require phone verification, and we do not see or store your phone number from that step.
Selling & Listings
How do I list on other marketplaces like Poshmark, Mercari, Facebook Marketplace, Depop, Vinted, Etsy or Whatnot?
eBay publishes directly from inside the app: open the item and click Publish. For every other marketplace, use our free Chrome extension. Open the item, click "Copy & Open", and the extension fills in that marketplace's listing form with your title, price, description and photos. You review the details, pick a category, and click Post. The extension needs a desktop browser, so if you are on a phone you will need to move to a computer for these marketplaces. eBay publishing works on any device.
Can I reorder photos or choose the main photo?
Yes, on any device. Open the item's page, tap the photo you want to move so it fills the large view, then open the three-dot "More actions" button in its top-left corner: "Make main photo" sends it to the front, and "Move left" and "Move right" shift it one place at a time. On a computer you can also drag the thumbnails into the order you want. The first photo is the main one: it leads the eBay listing and the paste kit for other marketplaces, and it is the image buyers see in search results. You can also add more photos there before you publish.
Which marketplaces can I list on?
You can publish listings directly to eBay (US, UK, Canada, Australia, Germany, France, Italy, Spain, Netherlands, Belgium) and Bonanza from inside the app. For the other marketplaces, install our free Chrome extension (desktop Chrome or Edge) and it fills in the listing form for you — you just review the details and hit Post. It works with Facebook Marketplace, Poshmark, Mercari, Depop, Whatnot, Vinted, OfferUp, Etsy, District, Craigslist, 1stDibs, and Ruby Lane. Prefer not to install anything? Every item page also has a paste kit: tap-to-copy buttons for the title, price, condition, and description (in the order the platform's form asks for them), a Share Photos button that sends all photos to your phone's share sheet, and a Download Images button that bundles them into one zip.
How do I cross-post the same listing to multiple marketplaces?
Two ways, depending on the marketplace. eBay (10 countries) and Bonanza publish directly from the app with one click, no extension needed. For everyone else, install our free Chrome extension (desktop Chrome or Edge): open any saved item and click to cross-list, and the extension opens that marketplace's create-listing form with your title, price, description, and photos already filled in — you review, pick the category, and hit Post. It works on Facebook Marketplace, Poshmark, Mercari, Depop, Whatnot, Vinted, OfferUp, Etsy, District, Craigslist, 1stDibs, and Ruby Lane. It runs entirely in your browser, so we never see your marketplace logins. Because it's a browser extension, cross-posting works on a desktop computer (Chrome or Edge), not the phone app. Prefer not to install anything? Every item page also has tap-to-copy buttons and a Download Images button, so you can paste into any platform's own app by hand.
Can I edit the AI-generated listing?
Absolutely. The AI generates a title, description, and suggested price as a starting point. You can edit every field before publishing. Many sellers use the AI output as-is, while others customize it to match their selling style.
How do I remove a photo I uploaded from an item?
Open the item from your Items list and tap the thumbnail of the photo you want gone, so it shows in the large view. In the photo's top-left corner there is a row of small buttons: tap the three-dot "More actions" button and choose "Delete Image", then confirm. The same menu can replace that photo with a new one or download it. This removes only that photo; the item and its other photos stay exactly as they were, and deleting the whole item is a separate action from the item's own menu. The buttons are always visible on a phone and appear when you hover on a computer, and the steps are the same on web, iPhone and Android.
Can I remove the background from my item photos?
Yes, on every plan, and it does not use a scan. Open the saved item, and in the photo viewer tap the eraser button in the photo's top-left corner (always visible on a phone, shown on hover on a computer) labeled "Remove background". The AI cuts out the item and places it on a plain white background in a few seconds. Your original is kept: a "Restore original" button appears on that photo to undo it. It works per photo, including photos imported from eBay. There is no cropping, rotate, or filter tool, so make those edits on your device first. If eBay seems to crop your photo on publish, that is the separate eBay Photo Style setting in Settings (choose "Fit whole item").
Can I list on eBay as an auction instead of fixed price?
Yes. At the review step of the eBay listing flow you'll see a Fixed price / Auction toggle. Auction opens up a start price, duration (1/3/5/7/10 days, default 7), and optional reserve and Buy It Now. The start price defaults to 50% of the estimated value since low starts historically attract more Watchers and bids, but you can change it to anything you want.
Can I end an eBay listing from Underpriced AI?
Yes. Open the item, look for the "End on eBay" button under "Listed on eBay." One click ends the listing on eBay directly — no need to go to Seller Hub. Ended listings show a Relist card: one tap brings the listing back live, optionally at a new price. (A relist is a fresh eBay listing, so watchers don't carry over — that's how eBay works.)
Can I change the price of a listing that's already live on eBay?
Yes. Open the item and you'll see your live listing card with a price field and an Update Price button — the new price pushes straight to eBay, no Seller Hub needed. There are also one-tap markdown chips (−5%, −10%, −15%) for quick price drops. If you've edited the title or description in the app, a "Push title & description to eBay" button updates those on the live listing too. One eBay rule to know: auctions that already have bids can't change price — eBay refuses that on every tool, not just ours.
Can eBay Best Offers be accepted automatically?
Yes. On your live listing's card, open Best Offer settings to enable offers with two optional thresholds: offers at or above your auto-accept price sell instantly, and offers below your minimum decline automatically — no more waking up to lowball offers waiting for a response. Fixed-price listings only (eBay doesn't do Best Offer on auctions).
Can I set a Promoted Listings ad rate when I publish to eBay?
Promoted Listings is eBay's own advertising and is set on eBay, not in the app. Listings published from a connected tool open on eBay in the "Revise your listing (with restrictions)" form, where the General promote toggle only applies the rate of the campaign the listing sits in and typing a different percentage flips back. To use a fixed rate such as 3%, open Seller Hub's Advertising dashboard (https://www.ebay.com/sh/ads/dashboard), edit your General campaign, switch the ad rate strategy to a fixed rate, and save. Every listing in that campaign then follows it. Or turn on Promote on eBay in Settings or at the publish step: pick one of your running General campaigns and every listing you publish live joins it at that campaign's rate.
Does the app fill in eBay's required item specifics for me?
Yes. When you pick a category and condition, the intake form loads any item specifics or structured condition details eBay requires for that specific category and pre-fills them from your scan when possible (Brand, Model, Coin Condition, Storage Capacity, and so on). You just fill in whatever's still blank and publish. No more "publish, fail, retype" round trips.
Can I schedule a listing to go live later?
Yes. On the publish screen you'll see a "Go live at" time picker with quick presets for Now, +6h, and Tomorrow, plus a custom picker if you want a specific date and time. eBay allows scheduling up to 21 days out. Or use the "Publish Live on eBay" button to go live immediately. The time is chosen per listing — there isn't a global default listing time setting that applies to every new listing automatically.
Does the listing include keywords for SEO?
Yes. Listing titles and descriptions are optimized with relevant keywords that buyers actually search for. This includes brand names, model numbers, size, color, condition descriptors, and category-specific terms to maximize visibility in marketplace search results.
Can I share a scan result with someone?
Yes. On any scan result, tap 'Share' to get a public link you can send to a buyer, a friend, or post anywhere. The recipient sees the item, the price range, and the recent sold comparables without needing an account. You can share before or after you list.
What happens to my listings if I cancel?
Listings already published to eBay or Bonanza stay live on those platforms - Underpriced AI never removes them. Your saved scan data is also preserved if you decide to resubscribe later.
Inventory & Tracking
Can I track my purchase price and profit?
Yes. When you save a scan, you can record the purchase price, and on any item page the Inventory card at the top holds Purchase Price, Where Found, Purchase Date, and Quantity. The app calculates estimated profit based on the suggested selling price minus your cost and estimated platform fees (eBay, Poshmark, Mercari, etc.). When items sell on eBay, the actual sale price and fees are auto-synced - no manual entry needed.
What does the Quantity field mean, and why does my title say 'box of 81' when I have 45?
Quantity on the Inventory card is how many identical lots you have to sell, and it becomes the listing quantity when you publish. One box of 81 tiles is Quantity 1. If you have a partial box, say 45 tiles, keep Quantity at 1 and edit the title and description on the item page so they say 45 tiles, partial box. The scan wrote 'box of 81' because that is what the packaging says, and it priced the item as a full box, so tap the price to set your own for the partial lot. Changing Quantity never changes the title, the description or the price.
What is the Sourcing Calculator?
The 'Should I Buy It?' calculator appears on every scan result. Enter what you'd pay for an item and estimated shipping cost, and it instantly shows your net profit and ROI on each platform (eBay, Poshmark, Mercari, Facebook). It's designed for in-the-field sourcing decisions - scan an item at a thrift store and know if it's profitable before you buy.
Does Underpriced AI sync with eBay automatically?
Yes. When an item you listed through Underpriced AI sells on eBay, we automatically pull the sale price, marketplace fees, and shipping charges via eBay's Fulfillment API. Your profit calculations update automatically - no manual data entry required.
What is the Death Pile Prioritizer?
On your dashboard, the Death Pile card ranks every item you've scanned but not yet listed, so you know what to list first. It scores each item on how long you've owned it, the category's sell-through speed, the profit potential, and the item's value, then tags each one URGENT, HIGH, MEDIUM, or LOW. The card shows an 'X unlisted' count and highlights how many are urgent - tap any item to jump straight to listing it.
Will I be notified if an item's value changes?
Not item by item, and we would rather say so than have you waiting on an email that isn't coming. What you do get is a weekly portfolio email covering what your inventory is worth, what sold, what you listed, the profit you realised, and what's trending in the categories you source. For a fresh number on one specific item, open it and tap Reprice - that re-runs it against today's sold comps on the spot. You can turn the weekly email off under Settings, Notifications.
How do I download or re-download my inventory as a CSV / Excel file?
There are two ways to export your full item list to a CSV (which opens straight into Excel or Google Sheets), and both are available on every plan: (1) On your Dashboard, use the 'Export' button in the toolbar - it downloads your items (name, brand, category, value, condition, and more), and it respects any filters you have applied. (2) On the Scan History page, use the export option to download all of your scans as a CSV (this is the file named 'underpriced-inventory-[date].csv'). You can re-download either one any time - the export is generated fresh each time, so there is nothing to find again; just click the button once more. Note: this is different from the 'Tax Report' on the Analytics page, which is a Schedule C accounting export for tax season, not your inventory list.
Can I export a tax report?
Yes. On the Analytics page, click 'Tax Report' to download a Schedule C-ready CSV for the current year. It includes per-item revenue, cost of goods sold (COGS), shipping costs, platform fees, other expenses, and net profit - plus summary totals. This makes tax season significantly easier for resellers.
What inventory features are included?
Pro Plus and Business plans include storage locations (organized hierarchically), custom tags for categorization, bulk operations (archive, delete, assign), and advanced filtering. This makes it easy to manage large inventories across multiple sourcing trips.
How do I record where an item is stored (bin, shelf, room, or a SKU for its location)?
Use Storage Locations (Pro Plus and Business plans). First create your locations under Settings > Storage Locations at underpricedai.com/settings/storage - they can nest, for example Garage > Shelf A > Bin 3. Then open any item from your Dashboard: the Inventory card at the top of the item page has a 'Storage Location' dropdown and your tags. It saves as soon as you choose. To move many items at once, tap 'Select' on the Dashboard, pick the items, and use Actions > Move to location. The Dashboard can filter by location. Each item can also carry your own SKU: the Inventory card's 'SKU / custom label' field, with a Suggest button that builds one from the location (Garage > Shelf A > Bin 3 becomes GAR-SA-B3 plus a short code). It prints on barcode labels and goes to eBay as the listing's custom label.
Can I print barcode labels and scan them to find an item?
Yes, on every plan. Open an item and use 'Print label' in the Inventory card, or select several items on the Dashboard and choose Actions > Print labels. Pick the Avery 5160 sheet layout (30 labels per letter page) or the 2.25 x 1.25 inch thermal layout for Dymo, Rollo, or Brother label printers, then print from your browser's print dialog. Each label carries a Code 128 barcode of the item's SKU plus the title and storage location; items without a SKU print a short code that works the same way. To find an item later, tap 'Scan label' on the Dashboard and point the camera at the label - the item opens.
How do I undo 'Mark as Listed' or set an item back to not listed?
Open the item and tap the status badge at the top of the item page (Analyzed / Listed / Sold): it opens a small menu with the status changes. The three-dot menu next to it has the same actions. While an item shows as Listed, you will see 'Unlist Item', which sets it back to Analyzed (not listed) without touching anything on a marketplace. Tapping the 'Analyze' step in the progress bar at the top of the item page does the same thing. This only changes the status flag in your inventory - if the item is actually live on eBay through Underpriced AI, end the listing from the Live Listings card on the item page instead, and the status updates on its own. Sold items have 'Mark as Unsold' in the same menu.
How do I delete an item from my inventory?
Open the item you want removed from the Items page - you'll find a delete option in that item's actions. On Pro Plus and Business plans, there's also a bulk-delete option under bulk operations if you want to clear several items at once. Deleting is permanent: once removed, the item's photos and valuation history are gone for good.
Is there an analytics dashboard?
Pro Plus and above (Business, Power, Scale) get the full analytics dashboard with revenue and profit reports, category performance analysis, inventory aging reports, sourcing ROI tracking, and tax report exports. This helps you understand which categories and sourcing methods are most profitable.
Platforms & Devices
Can I use Underpriced AI inside ChatGPT or Claude?
Yes. We run a connector (an MCP server) that plugs Underpriced AI into Claude, ChatGPT and coding assistants like Cursor and VS Code. Once it is connected you can ask the assistant to price an item, pull the real sold comps behind that price, get a worth-it verdict on a potential buy, or draft an eBay listing, all without leaving the chat. It never publishes a listing on its own; anything it drafts waits for you. Setup instructions for each assistant are at underpricedai.com/mcp.
Do you have an API we can build into our own product?
Partly, and it is worth being precise about which part. The MCP server above is a real programmatic interface to the same pricing engine our apps use: price an item from a photo, pull the sold comps behind that price, and a worth-it check against a cost. What it does not have yet is a service-key or machine-to-machine login, which is what a server-side integration inside another product normally needs. It signs in a person through OAuth, so it suits an assistant acting on someone's behalf rather than your servers pricing items on their own. If you are building something that would price at volume inside your own platform, write to support@underpricedai.com with your expected monthly volume and whether you would be sending photos or text descriptions, and Frank will answer directly. We have set up flat per-item volume arrangements outside the standard plans before.
Does Underpriced AI work on mobile?
Yes. The web app is fully responsive and works on any smartphone or tablet. We have a dedicated iOS app on the App Store and an Android app on Google Play, both with native camera integration for the fastest scanning experience.
Is there a Chrome extension?
Yes, and it does two things. First, scan from anywhere: right-click any product image while browsing online listings, thrift store websites, or auction sites for an instant valuation. Second, one-click cross-listing: on any of your items, one click opens the create-listing form on Facebook Marketplace, Poshmark, Mercari, Depop, Whatnot, Vinted, OfferUp, Etsy, District, Craigslist, 1stDibs, and Ruby Lane, and fills the title, price, description, and photos — you review, pick the category, and click Post. It runs entirely in your browser and we never see your marketplace logins.
Can I cross-list to Facebook Marketplace, Poshmark, Mercari, and other marketplaces?
Yes. On desktop Chrome, install our free extension and every item gets one-click cross-listing to Facebook Marketplace, Poshmark, Mercari, Depop, Whatnot, Vinted, OfferUp, Etsy, District, Craigslist, 1stDibs, and Ruby Lane: we open the marketplace's own create form and fill the title, price, description, and photos — you review and click Post, so nothing is ever posted without you. On mobile, each item page has a paste kit that copies every field in the order the form asks, plus one-tap photo sharing. eBay and Bonanza go further with full direct publishing from inside the app.
Do you support international sellers?
Yes. eBay integration supports 10 countries — US, UK, Canada, Australia, Germany, France, Italy, Spain, Netherlands, Belgium — and pricing data is localized to your marketplace and currency. Italian users get sold-comp data from ebay.it in EUR, UK users from ebay.co.uk in GBP, and so on. The identification and listing features work globally regardless of country.
Why does signing up with Google send me back to the create-account page?
This almost always means the browser is blocking the cookies or scripts Google sign-in needs to hand you back to us. The usual cause is opening the site inside another app's built-in browser (a link tapped in Gmail, Facebook, or a text message) or a strict privacy or ad-blocking setting. Two fixes: first, open Chrome or Safari directly, type underpricedai.com in the address bar, and tap Continue with Google from there rather than following a link inside another app. Second, if it still loops, create the account with your email and a new password instead (not your Google password) — you'll get a confirmation email and you're in, and you can connect Google to the account later in Settings.
Security & Privacy
Is my data secure?
Yes. Images are stored securely in encrypted AWS S3 storage. Platform connections use OAuth - we never see or store your marketplace passwords. We support two-factor authentication (2FA) for additional account security.
Can I delete my data?
Yes. You can delete individual scans or disconnect a marketplace account at any time without touching the rest of your account.
How do I permanently delete my account and all my data?
This is separate from canceling. Canceling or pausing your plan just stops billing - your account, scans, and history stay. To permanently delete everything, go to Settings and use Delete Account, or visit underpricedai.com/delete-account and enter your email for a one-click deletion link (no login needed; the link expires in 30 minutes). Deletion is permanent and removes your account, scan history, saved items, and listings - it can't be undone.
Do you sell my data?
No. We never sell your personal information or scan data to third parties. Your scans and inventory data are yours. See our privacy policy for full details.
Reselling Tips
What are the best items to resell for profit?
Popular high-margin categories include vintage clothing (Levi's, Pendleton, Starter jackets), collectibles (Hot Wheels, Pyrex, depression glass), electronics, designer handbags, and athletic wear (Lululemon, Nike Dunks). Check out our blog for detailed guides on each category.
Where should I source items to resell?
Thrift stores, estate sales, garage sales, flea markets, and online auctions are the most popular sourcing spots. Our Sale Finder feature (Pro Plus and above) helps you find nearby estate sales and auctions based on your ZIP code.
Which marketplace should I sell on?
It depends on what you're selling. eBay is best for electronics, collectibles, and niche items. Poshmark excels for clothing and fashion. Mercari works well for general goods. Facebook Marketplace is ideal for large or local-pickup items. Many successful resellers cross-list on multiple platforms to maximize exposure.
