Best Reselling Apps in 2026: Tools Every Flipper Needs

Running a reselling business in 2026 means juggling sourcing, pricing research, listing creation, photography, cross-posting, and sales tracking. No single app does everything perfectly. The best resellers build a toolkit of apps that complement each other, automating the parts of the business that eat up the most time.

This guide breaks down the best reselling apps across every category: selling platforms, pricing tools, cross-listing software, and sourcing utilities. Whether you flip thrift store finds on weekends or run a full-time operation, these are the tools worth knowing about.

How We Evaluated These Reselling Apps

Before diving into the list, here is what we looked at for each app:

• Core functionality -- What does it actually do well?
• Pricing -- Is it free, freemium, or subscription-based?
• Ease of use -- How steep is the learning curve?
• Value for resellers -- Does it save time or increase profits relative to cost?

We included a mix of selling platforms, pricing tools, and workflow software because most resellers need apps from multiple categories to run efficiently.

The Best Reselling Apps for 2026

1. eBay App

Best for: The widest audience and most item categories

The eBay app remains the backbone of most reselling businesses. With over 130 million active buyers, eBay offers reach that no other resale platform can match. The mobile app lets you create listings, manage inventory, respond to buyers, print shipping labels, and track sales from your phone.

The built-in barcode scanner pulls up product details automatically for retail items, the app handles both auction and fixed-price formats, and the Seller Hub dashboard provides sales analytics for serious sellers.

Pricing: Free to list (up to 250 listings/month), then $0.35 per listing. Final value fees range from 13.25% to 15% depending on category.

Pros:

• Largest buyer pool of any resale marketplace
• Supports virtually every product category
• Global Shipping Program expands international reach
• Promoted Listings available for extra visibility

Cons:

• Fees add up, especially with promoted listings
• Buyer-friendly return policies can frustrate sellers
• Listing creation has more fields than simpler platforms

2. Poshmark

Best for: Clothing, shoes, and fashion accessories

Poshmark has carved out a dominant position in fashion resale. The app's social features -- sharing, following, Posh Parties -- create an engaged community of buyers and sellers. If you specialize in clothing, handbags, or shoes, Poshmark should be near the top of your list.

The listing process is straightforward: snap photos, add a description, set a price, and share. Poshmark handles shipping with a flat-rate prepaid label, which simplifies the process but can be expensive for lightweight items.

Pricing: Free to list. Poshmark takes a flat $2.95 commission on sales under $15 and 20% on sales $15 and above. Shipping is a flat rate paid by the buyer.

Pros:

• Strong community drives organic sales through sharing
• Flat-rate shipping simplifies logistics
• Posh Parties create themed selling events for exposure
• Offers to Likers feature helps close sales

Cons:

• 20% commission is higher than most platforms
• Flat-rate shipping overcharges on lightweight items
• Primarily fashion-focused, limiting for general resellers
• Requires active engagement (sharing) to maintain visibility

3. Mercari

Best for: General items with a quick, simple listing process

Mercari appeals to resellers who want simplicity. The app is clean, the listing process is fast, and the buyer demographic skews younger. It works well for a broad range of items: home goods, electronics, toys, clothing, and more.

Mercari has also expanded its local selling option, letting buyers pick up items to avoid shipping. For sellers dealing in furniture or other heavy items, this is a real advantage.

Pricing: Free to list. Mercari charges a 10% selling fee plus 2.9% + $0.50 payment processing on each sale.

Pros:

• Simple, fast listing flow
• Lower fees than Poshmark
• Wide category coverage
• Local pickup option for large or heavy items

Cons:

• Smaller buyer pool than eBay
• Lower average sale prices
• Less search visibility for niche or collectible items
• Limited seller tools compared to eBay

4. Facebook Marketplace

Best for: Local sales, furniture, and avoiding shipping entirely

Facebook Marketplace has become the go-to platform for local reselling. There are no listing fees, no selling fees for local transactions, and no shipping hassles. If you source furniture, large appliances, or anything that would be expensive to ship, Marketplace is essential.

The downside is a lack of structure compared to dedicated platforms: no standardized shipping, inconsistent buyer quality, and frequent lowball offers. It works best as a supplement to other platforms.

Pricing: Free for local sales. Shipped orders have a 6% selling fee (minimum $0.70).

Pros:

• No fees on local sales
• Huge user base through Facebook
• Great for large items that are costly to ship
• No listing limits

Cons:

• Flaky buyers and frequent no-shows for local pickups
• Constant lowball offers
• No structured seller protection for local transactions
• Limited search and discovery compared to dedicated marketplaces

5. Underpriced AI

Best for: AI-powered pricing research and eBay listing generation

Underpriced AI takes a different approach from the other apps on this list. Instead of being a marketplace, it is a pricing and listing tool designed to speed up the most time-consuming parts of reselling: figuring out what something is worth and writing a compelling listing.

The workflow is simple. You photograph an item, and the AI identifies it, pulls comparable sales data from eBay and other marketplaces, and returns a price range with a recommended listing price. From there, it generates an SEO-optimized eBay title and description that you can push directly to your eBay account. It also includes background removal for product photos.

For resellers who spend hours every week researching prices on eBay sold listings, this is where the time savings stack up. The AI handles the identification and comp research in seconds rather than minutes per item.

Pricing: Free trial with 3 scans. Pro plan at $9/month (45 scans), Pro Plus at $19/month (110 scans), and Business at $49/month (300 scans). Scan packs are also available pay-as-you-go starting at $3 for 5 scans.

Pros:

• AI identification and pricing saves significant research time
• Generates ready-to-post eBay listings with optimized titles
• Direct eBay integration across US, UK, Canada, Australia, and Germany
• Background removal included on all plans
• Affordable entry price

Cons:

• Focused on pricing and listing, not a marketplace itself
• Scan limits on lower-tier plans may not suit very high-volume sellers
• Best suited for eBay sellers; limited marketplace coverage beyond eBay and Bonanza
• AI pricing accuracy depends on item type (common items fare better than ultra-rare ones)

If you want to understand how AI pricing tools fit into a broader reselling strategy, our pricing guide for resellers covers the topic in depth.

6. WorthPoint

Best for: Antiques, collectibles, and deep historical pricing research

WorthPoint is the gold standard for researching antiques and collectibles. Its database contains over 610 million historical sold prices aggregated from auction houses and online marketplaces going back to 2006. If you deal in vintage items, pottery, art, coins, or anything where standard eBay comps fall short, WorthPoint fills the gap.

The platform also includes a marks database with over 200,000 makers' marks, autographs, and symbols for identification, plus a digital library of reference books. For collectors and antique dealers, this depth of data is unmatched.

Pricing: Price Guide plan at $28.99/month, Price Guide + Marks at $37.99/month, All Access at $46.99/month. Annual subscriptions save 15-20%. Free 7-day trial available.

Pros:

• Deepest historical pricing database for antiques and collectibles
• Marks database helps identify unknown items
• Digital library of reference books included on higher plans
• Data sourced from major auction houses, not just eBay

Cons:

• Expensive for casual resellers
• Overkill if you primarily sell modern retail items
• Mobile app has mixed reviews
• No listing creation or marketplace integration

If you regularly source at estate sales and antique shops, WorthPoint pays for itself the first time it helps you identify a valuable piece you would have otherwise passed on or underpriced.

7. Google Lens

Best for: Free, instant item identification while sourcing

Google Lens is the most underrated tool in a reseller's toolkit, and it is completely free. Point your phone camera at any item and Google Lens will identify it, show you visually similar products, and link to shopping results with current prices.

It does not replace dedicated pricing tools, but it is invaluable for quick identification in the field. Wondering if that vintage lamp is worth picking up? Google Lens can tell you the brand and approximate value in seconds.

Pricing: Free.

Pros:

• Completely free
• Instant visual identification
• Works on virtually any item category
• Built into the Google app on most phones

Cons:

• No sold price data, only current listings and retail prices
• Cannot generate listings or integrate with marketplaces
• Accuracy varies for generic or unmarked items
• Not designed specifically for resellers

8. Vendoo

Best for: Cross-listing to multiple marketplaces from a single dashboard

Vendoo is a cross-listing tool that lets you create a listing once and push it to multiple platforms including eBay, Poshmark, Mercari, Depop, Etsy, and more. If you sell on three or more marketplaces, manually creating separate listings for each one is a massive time sink. Vendoo cuts that process down significantly.

The platform supports up to 11 marketplaces and includes auto-delisting when an item sells, background removal, and basic analytics. The trade-off is a pricing model that can get complicated with add-ons for importing, bulk operations, and full marketplace access.

Pricing: Free plan (5 listings/month). Paid plans: Starter $8.99/month (25 listings), Simple $19.99/month (125 listings), Plus $29.99/month (250 listings), Pro $49.99/month (600 listings), Unlimited $69.99/month. Add-ons for importing, bulk operations, and all-marketplace access range from $4.99 to $11.99/month.

Pros:

• Supports 11 marketplaces from one interface
• Auto-delisting prevents double sales
• Free plan available to test the platform
• Background removal on all plans

Cons:

• Essential features locked behind add-ons (importing, all marketplaces)
• Per-listing limits on most plans
• No AI listing generation
• Total cost can climb quickly with add-ons

9. List Perfectly

Best for: High-volume cross-listing with community features

List Perfectly is Vendoo's main competitor in the cross-listing space, using feature-based pricing rather than per-listing limits. It supports 11 platforms with unlimited importing, relisting, and delisting on all plans, plus a community component with "Listing Party" events where sellers list together live.

It stands out with its AI listing assistant and built-in pricing research tools including Google Lens integration and eBay pricing lookup. The Simple plan at $29/month includes unlimited cross-listing to all marketplaces with no add-on fees.

Pricing: Simple $29/month, Business $49/month, Pro $69/month, Pro Plus $99-$249/month. No annual discount. 5-day free trial available.

Pros:

• Unlimited cross-listing on all plans (no per-listing caps)
• All marketplaces included without add-ons
• AI listing assistant included
• Active seller community and educational events
• Built-in pricing research tools

Cons:

• No annual billing discount
• Advanced features like auto-sales detection require Pro plan ($69/month)
• Higher starting price than Vendoo
• Mobile app restricted to Pro Plus plan ($99+/month)

10. SellerAmp SAS (with Keepa)

Best for: Amazon FBA arbitrage and wholesale sourcing

SellerAmp SAS is purpose-built for Amazon sellers doing retail or online arbitrage. It answers three critical questions for every product: Can I sell it? Does it sell? Is it profitable? The tool checks selling eligibility, hazmat and IP risk flags, estimated sales volume, and calculates profit margins including all Amazon FBA fees.

Paired with Keepa for historical price and rank charts, SellerAmp gives Amazon sellers the data they need for fast sourcing decisions. The Chrome extension works on any website, and the mobile app supports barcode scanning for retail arbitrage.

Pricing: Getting Started at $20/month (1,000 lookups), Getting Serious at $30/month (unlimited lookups). Annual plans available at $200/year and $300/year respectively. Keepa is separate at around $23/month.

Pros:

• Comprehensive Amazon product analysis in one tool
• Chrome extension, web app, and mobile app included
• Profit calculator accounts for all Amazon FBA fees
• Keepa integration for historical price and rank data
• Fast eligibility and restriction checks

Cons:

• Only useful for Amazon sellers
• Requires separate Keepa subscription for full value
• Learning curve for new Amazon sellers
• Not relevant for eBay, Poshmark, or other marketplace sellers

How to Build Your Reselling App Stack

No single app covers everything. The best approach is to layer apps by function:

For selling: Start with eBay as your primary platform. Add Poshmark if you sell fashion, Mercari for general goods, and Facebook Marketplace for local sales of bulky items.

For pricing: Use Google Lens for free, in-the-field identification. Add a dedicated pricing tool like Underpriced AI for eBay-focused research and listing generation, or WorthPoint if you specialize in antiques and collectibles.

For cross-listing: If you sell on three or more platforms, add Vendoo or List Perfectly to avoid duplicating listing work.

For Amazon: If you do any FBA arbitrage, SellerAmp paired with Keepa is the standard toolkit.

The resellers who scale fastest are not necessarily the ones who source the most. They are the ones who eliminate wasted time on pricing, listing, and administrative tasks, freeing up hours to find more inventory.

Matching Reseller Software to Your Business Stage

Your ideal app stack changes as you grow. Beginners should start lean with the eBay app, Google Lens, and a free trial of a pricing tool to learn the ropes without monthly costs eating into thin margins. Part-time flippers handling 20-50 items per month benefit from adding a second marketplace and a dedicated pricing tool like Underpriced AI ($9/month) or WorthPoint for antiques. For ideas on what to source at this stage, see our guide to the best items to flip for profit. Full-time resellers listing 100+ items monthly should add a cross-listing tool and consider Amazon FBA tools if they sell on that platform. At high volume, every minute saved per listing compounds.

Final Thoughts on the Best Reselling Apps

The reselling app landscape in 2026 has solid options for every part of the workflow. Marketplace apps get your items in front of buyers. Pricing tools help you avoid leaving money on the table. Cross-listing software saves hours of duplicate work. And Amazon-specific tools serve the FBA niche.

The right combination depends on what you sell, where you sell it, and how much volume you handle. Start with free tools, add paid subscriptions as your volume justifies the cost, and always measure whether a tool is actually saving you time or making you money. The best reselling app is the one you actually use consistently.
