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 download an app?
Underpriced AI works in your browser on any device — no download required. We also offer a native 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 trial?
Yes! Every new account gets 3 free scans with no credit card required. This lets you try the full scanning and listing experience before choosing a plan.
Pricing & Accuracy
How accurate is the AI pricing?
Our pricing is based on real recently sold data from eBay, Poshmark, Mercari, Facebook Marketplace, Etsy, and Depop — not AI guesses. Every scan includes comparable sold listings with clickable links so you can verify prices yourself. Accuracy depends on image quality and how common the item is. For high-value or rare items, we recommend cross-referencing the comparable sales we provide.
Where does the pricing data come from?
Pricing data comes from recently sold listings across multiple platforms including eBay, Poshmark, Mercari, Facebook Marketplace, Etsy, and Depop. We also check active listings to gauge current market supply. This cross-platform approach gives you a more complete picture than any single marketplace.
How is this different from checking eBay sold listings manually?
Manual research typically takes 5-10 minutes per item and only covers one platform. Underpriced AI searches sold data across six platforms simultaneously, factors in item condition and specifics from your photo, and delivers results in seconds. It also generates a listing title, description, and suggested price — saving you significant time per item.
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 general identification. Clear, well-lit photos dramatically improve accuracy.
Plans & Billing
What plans are available?
We offer three paid plans: Pro ($12/month, 30 scans), Pro Plus ($24/month, 75 scans with inventory tools), and Business ($59/month, 200 scans with analytics dashboard). Annual billing saves 20%. 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. Viewing previously saved scan results does not use a scan.
Can I change or cancel my plan?
Yes, you can upgrade, downgrade, or cancel your subscription at any time from your account settings. If you cancel, you keep access through the end of your current billing period. Your saved scans and data are preserved.
Do you offer refunds?
We offer refunds on a case-by-case basis. If you're not satisfied, contact us within 14 days of your purchase and we'll work with you to make it right.
What happens when I run out of scans?
When you reach your monthly scan limit, you can purchase additional scan credit packs (10, 25, or 50 scans) or upgrade to a higher plan. Credit packs never expire and carry over month to month.
Selling & Listings
Which marketplaces can I list on?
You can publish listings directly to eBay (US, UK, Canada, Australia, and Germany) and Bonanza from within the app. The generated titles and descriptions are also optimized for Poshmark, Mercari, and Facebook Marketplace — just copy and paste.
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.
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.
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. 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 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, Etsy). 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?
The 'List Next' feature on your dashboard scores all your unlisted (scanned but not listed) items and ranks them by urgency. It considers how long you've had the item, the category's sell-through rate, profit potential, and item value to tell you exactly what to list first. Items are tagged as URGENT, HIGH, MEDIUM, or LOW priority.
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.
Is there an analytics dashboard?
Business plan subscribers get a 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
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. The Underpriced AI Chrome extension lets you scan items while browsing online listings, thrift store websites, or auction sites. Right-click any product image to get an instant valuation.
Do you support international sellers?
Yes. While pricing data is primarily based on US market data, the identification and listing features work globally. eBay integration supports US, UK, Canada, Australia, and Germany accounts.
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, disconnect marketplace accounts, or delete your entire account and all associated data from your settings page at any time.
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.
