Questions, answered plainly.

Windows 10 or 11, an eBay UK seller account and your own free eBay developer keys. Sellhelm carries its own runtime, so there is nothing else to install. Google Chrome is needed for the extension, which eight built-in shops depend on. The setup guide has every step.

eBay issues developer keys to one seller and does not allow sharing them. Using your own also keeps your eBay usage limits yours alone. It takes about 15 minutes, is free, and Sellhelm's Settings page walks you through every click, including the account-deletion question eBay asks.

Install and activation take a few minutes. Connecting eBay is the long step, about 15 minutes, because you create your own developer keys (eBay can take up to a day to approve a brand-new developer account). After that, adding and pricing a product takes a couple of minutes.

Not at the moment. Sellhelm is for Windows 10 and 11 and eBay UK, and its fee and VAT sums are built for UK sellers.

No. You can start from an empty shop and add products from supplier links. If you already sell, one press of Sync with eBay brings your live listings in as products with watching switched off; you then add each one's supplier page and tick Watch.

Open Windows Settings, go to Apps, find Sellhelm and choose Uninstall (or use Uninstall Sellhelm in the Start menu). It asks whether to delete your data too: keep it if you may reinstall. Then remove the extension from Chrome. See updating and removing.

You choose the return you want on what you spend, 25% by default. Sellhelm solves for the eBay price after the final value fee, the per-order fee, the regulatory fee and the VAT on all of them, using eBay's published rate for each product's category. See how pricing works.

You choose: every 30 minutes up to every 24 hours, four hours by default, with quiet hours if you want them. You can also check everything at any moment with one button.

Automatic checks run while Sellhelm is running on your PC. It runs quietly with a small icon by the clock, and Setup can start it for you whenever you sign in to Windows. The Chrome extension only reads its shops while Chrome is open. If your PC is off, nothing is checked, and it catches up when you next start it.

When a supplier's price would move your eBay price by more than your limit (25% unless you change it), Sellhelm does not send it. It holds the change on the Products page with the old and new figures and a Send it now link. A stock-out is still sent while a price is held, so you never sell something you cannot get.

Not on its own. When a supplier sells out Sellhelm sets the quantity to 0, and it first reads eBay's out-of-stock setting. If that setting is off, quantity 0 would end the listing, so Sellhelm holds the change and tells you how to switch the option on. Only the Remove button ends a listing, and it asks first.

Then nothing happens to that listing. Sellhelm never acts on a reading it does not understand, and it flags the product so you can look. If too many pages fail at once it sends nothing at all.

32 shops have their own reader: 16 are read directly, 8 gently, one page at a time, and 8 through your own Chrome. The suppliers page lists every shop and what to know about it.

Yes. Paste any product page and Sellhelm reads it with its general reader, which understands the standard product data most shops publish. If the shop refuses Sellhelm, the Chrome extension can read it after one click of permission. Shops without standard data may need a reader written; ask from your account.

It combines eBay's own suggestion with its own matching against eBay's category list, and shows you the result to change. Fee rates follow the category chosen.

eBay allows it where you are responsible for the item, your listing is accurate, and you meet eBay's dispatch and returns rules. Some ways of sourcing are not allowed. You are responsible for following eBay's rules and each supplier's terms of use, because some shops forbid automated reading, and product photos and text belong to their owners.

Not automatically. Sellhelm reads what a supplier's page publishes, but the rights to those photos and words belong to someone. Check you may use what you list.

One licence lets Sellhelm run on one Windows PC. Solo has one licence, Pair two and Crew five. You can use them on different PCs in your business.

Buy, create a password on the thank-you page, install Sellhelm, and copy the Machine ID from its Activate screen into your account. Your key appears there, and is emailed to you (if that email does not arrive, look in your spam or junk folder). Paste it into the Activate box.

A reinstall or new PC gives a new Machine ID. Send the new one from your account and move the licence to it yourself, twice. After that, open a support request and we will help.

No. A licence is a signed line of text that Sellhelm checks on your computer, offline. It works without an internet connection, and no licence server can switch it off.

Each licence runs its own copy with its own data, so two PCs on one eBay account would each watch and change listings independently. That is fine for separate shops or a team that splits the work, but not two copies on the same listings. You can move your data between PCs with Export everything and Restore.

Every 4.x update is included and appears in your account to download. Update by downloading the new Setup and running it; it replaces the program and keeps your data and eBay sign-in are kept. If a future major version ever needs a new licence, you will be told before anything changes, and the version you have keeps working.

No. You pay once. There are no per-listing fees and no monthly charge.

Tell us within 14 days and we refund you in full. Your licences are then cancelled and you uninstall the program. The refund policy has the detail.

No, but there is a 14-day money-back guarantee, which is a better test: you use it on your own real shop and, if it is not for you, you get every penny back.

No. Payment is taken in a secure card form run by Stripe. Your card details never reach this website.

It does not promise profit or sales, and nothing honest can. What it does is prevent the avoidable losses: selling below cost after a supplier price rise, and selling things your supplier has run out of. The rest is your products and your marketing.

No. It keeps its database in a folder on your PC and talks only to eBay and to your supplier shops. There is no Sellhelm account inside the program and no analytics. See how your data is handled.

No. Names and addresses are read from eBay when you open an order, shown on screen and never saved. That is also what lets you truthfully tell eBay you do not persist their data.

Sellhelm keeps a backup every day and before anything risky, in its data folder. Export everything writes one file that restores onto a fresh install, so copy one somewhere safe now and then. Your eBay keys are deliberately not in that file, so you type them again.

No. It runs only on the shop pages you have allowed and on Sellhelm's own page on your computer. It refuses to open eBay account pages, addresses on your own network and anything that is not an ordinary public website, and it never tries to solve a captcha.

Sellhelm is not yet code-signed, so Windows SmartScreen may warn on first run. Choose "More info", then "Run anyway". Each download page shows the file's SHA-256 so you can confirm it is genuine.

Sellhelm carries its own copy of Node.js so you install nothing else, and some antivirus tools are cautious of that. Add the install folder to the allowed list, or send us the name of the warning through your account.

Stop Sellhelm (right-click its icon by the clock), delete the file panel-lock.json in its data folder, and start it again. Nothing else is touched.

The setup guide covers the usual suspects, from a port already in use to an activation that says "different computer". Still stuck? Buyers can open a support request from their account and attach Sellhelm's support report.
