Find products that actually sell. Prove they make money.

Competitor research starts from a seller: you pick someone who is doing well and Sellhelm finds where their winners come from. Product research starts from the product: you say what you are interested in (or nothing at all), Sellhelm finds products at your suppliers, and checks each one on eBay to see whether it sells and makes money. Use the first to copy a proven seller, the second to find something nobody has pointed you to.

No. Product research reads supplier pages and eBay's public information, which never spends a search credit. Credits are only spent when Competitor research finds a supplier for a listing.

For every product it finds on eBay it shows how many sellers already list it, the price they charge, how many each listing has sold in total and how many people are watching. Where your browser is signed in to eBay, eBay also shows how many of that product sold in the last 90 days, and Sellhelm uses that too. Where eBay does not show it, Sellhelm says so and judges demand from the sales and watchers on the listings.

No - it is a ranked, evidence-based shortlist, not a promise. Worth selling means the product meets the profit, return, sales and competition thresholds you set, at a price eBay buyers are really paying. You can change the thresholds at any time and every verdict is worked out again at once. Always look at the product and its reasons before you buy stock.

With the same engine that prices your listings: the product's supplier price, your own eBay fee settings, the supplier's delivery cost, at a selling price taken from what the matching eBay listings really charge - a little under the middle, so it is neither wishful nor a race to the bottom.

10 shops on the US side today, including Amazon and AliExpress. Only shops whose search pages have been proven to work are used, and the list grows. You can search all of them or tick just the ones you want - Amazon alone, say.

As many as you ask for, from a hundred to a thousand and beyond, or "keep going until I stop it". It works at a steady pace that the suppliers and eBay are comfortable with, so a big run is something you start in the evening and read in the morning. If eBay or your browser needs attention it pauses, says why and carries on when you press resume.

Yes for most of it. Sellhelm reads many suppliers, and eBay's own pages, through your own browser, the way you would. It uses one window, closes it when it has finished and never leaves empty tabs behind. The eBay search it does first needs only your eBay connection.

Yes. Every run is saved and survives restarting Sellhelm. Add the products you like to Drafts in one click, download any run as a spreadsheet, and hide the ones you have already decided against.
