Source, prepare and sell on eBay

What 40thieves does

• Your eBay account, minus the tab-switching. — Connect eBay once. Your listings, orders and real fees come together in one place — and every listing shows what it earns, not just what it sells for.
• Bring the supplier catalogue in without retyping it. — Give 40thieves an item ID or a product URL and it pulls the images, attributes and price — then keeps the price current, so the cost you plan against is the cost you checked.
• A price you can defend, calculated from the cost you actually paid. — Purchase cost, shipping, duty, eBay fees and your target margin, in one calculation you can read. You get a floor, a target and a ceiling — and a list of what needs attention.
• From a supplier page to a listing you would publish. — 40thieves cleans and composes your images to one style, checks the data against a real catalogue, and writes a draft for your marketplace. Ready for your review, not your retyping.
• The part of selling that happens after the listing goes live. — Orders come in, costs arrive from three places, and stock quietly stops being accurate. One view keeps it: what sold, what it cost, what the fees took and which preset fits the parcel.
• Know what the market is doing before you move a price. — Comparable offers from your home market, measured as a reference you can defend. And a read of a competitor's shop: their price spread, their categories and where their listings are weak.
• The numbers that decide what you do next week. — What sold and at what real margin, what has been sitting, how prices moved against what you paid, and which listings get seen but not bought. Plus reports you can hand over.
• Your shop stays yours. Full stop. — You keep the keys. Your account sits behind its own walls, every request is checked, and your orders never touch another shop. That is not a promise on a page — it is how the thing is built.
