Before your first scan
Questions, answered clearly.
Try an item you already know
A familiar item makes the identification, comparable listings, and profit math easy to judge for yourself.
Test a known itemChatGPT can help you think through an item, and eBay sold listings are useful raw evidence. Underpriced puts the full buying decision in one reseller workflow. It identifies the item from photos or a listing screenshot, checks sold and listed comps, factors in your buy price, selling fees, shipping, and condition, then shows projected profit, ROI, selling velocity, and a Flip or Pass verdict. You can inspect the comps and carry the same item into a listing draft, PhotoStudio, and Flip Tracker without entering everything again.Compare reseller apps

From recent sold listings on eBay, plus Poshmark and Mercari when available, and current eBay listings. Every result shows how many sales the estimate rests on. Free checks show the count, titles and dates of those sales, and paid plans show the sold prices and links to the listings themselves.
Underpriced uses a versioned U.S. fee policy with category tiers and per-order charges where they apply. When buyer shipping or tax is unknown, we show an estimated range because the final amount can depend on the order, jurisdiction, seller status, and optional marketplace services.
No. Underpriced creates listing drafts with a title, description, and item specifics. You review the draft, make any changes, and publish it on the marketplace yourself. Underpriced does not publish, cross-list, or sync live listings.
No. Underpriced (underpriced.app) and Underpriced AI (underpricedai.com) are separate products from different teams, and we are not affiliated with them.
