From download to your first listing.

You need four things. Only the first two cost anything, and you probably have them.

• A Windows 10 or 11 PC. Sellhelm carries its own runtime, so there is nothing else to install first.
• An eBay US seller account that you already sell on.
• Your own free eBay developer keys. eBay issues these to one seller and does not allow sharing, so everyone makes their own. Sellhelm walks you through it.
• Google Chrome, for the extension. Some shops are read through it.

Sign in to your account, download the Setup file (named like Sellhelm-Setup-4.x.x.exe) and double-click it. A normal Windows wizard takes you through it: a welcome page, a short page saying what it will do, then Install and Finish. It takes about a minute, and there is nothing to unzip.

It installs into your own user profile, so it never asks for an administrator password and never touches other users on the PC. It adds Sellhelm to your Start menu with its own icon (and a Desktop icon if you check that), and lists itself under Windows Settings, Apps so you can uninstall it like any other program. Nothing else is left on your Desktop. If an older copy is running it is stopped for you first.

Open Sellhelm from the Start menu, or from the last page of Setup. A small Sellhelm icon appears by the clock (right-click it to stop Sellhelm) and your browser opens the panel, which starts on an Activate screen showing this computer's Machine ID.

Copy it, sign in to your account and paste it against a license. Your license key appears there straight away (and in an email). Paste it back into the Activate box. At that moment Sellhelm connects to our website once to confirm the license (it sends the key, the Machine ID and the Sellhelm version, nothing else), so you need an internet connection for that step. After that it works offline, apart from a small daily check for canceled licenses that it skips quietly if there is no connection.

Sellhelm starts with sensible defaults, listed here. Choose the return you want, decide how big a jump should wait for you, and enter your state's income tax percentage for the tax estimates. Fee rates are settings too, so they stay right when eBay changes them.

Sellhelm refuses settings that would misprice your shop, such as a floor above a ceiling, and tells you why.

On Add, paste a supplier product link. Sellhelm reads it and makes a draft with the price, stock, photos, specification and a suggested eBay category. Nothing is on eBay yet.

1. Open the supplier's own page beside the draft
2. Compare the facts, then check the box I have compared these
3. Press Check with eBay first to ask if eBay would accept it
4. Press the button that lists the checked drafts on eBay

Turn on automatic checking. A good way to begin is check only, which reads your suppliers and updates the figures without touching eBay, so you can watch what it would do. When you trust it, add send the changes to eBay.

Your Overview shows what needs you, most urgent first. A backup is kept every day, and Export everything gives you one file that restores onto a fresh install. Leave Sellhelm open on your PC: automatic checks run while it is running.
