Go to Import → Connect a Marketplace and press Connect on the eBay tile. You will be asked one question first, then sent to eBay's own sign-in page.
The question it asks first: which bank account?
Before the connection starts, SalesImporter asks which of your bank accounts eBay pays into.
This is not a formality. An eBay payout is money moving from eBay owes you to your bank — and bookkeeping has to record both ends. If SalesImporter does not know where the money lands, it can record that eBay released a payout but not where it went, and your books stop matching your bank.
Pick the account you actually see the deposits in. If it is not in the list yet, add it to your Chart of Accounts first.
What happens at eBay
You are sent to eBay's own sign-in and consent screen. You type your password on eBay's site, never into SalesImporter — this app never sees or stores your eBay password. eBay shows you exactly what access is being granted, you approve it, and eBay sends you back.
You can revoke that access at any time, either from the Import screen here or from your eBay account settings directly.
What it reads
Orders, fees, refunds and payouts — the financial record of what you sold and what it cost you to sell it. Enough to produce your books, and nothing beyond that.
What happens next
The first sync starts immediately and can take a few minutes if you have a lot of history. After that it runs nightly on its own.
How far back it reaches depends on your plan, and it is measured from the day you signed up, not from the day you connect. That is deliberate: a window measured from "now" would shrink every day you waited to connect, and you would quietly get less history for having taken your time.
A starting balance, not a guess
eBay is usually holding money for you the day you connect — sales that have completed but not yet paid out. Those started before your history window, so the orders behind them are not something SalesImporter can import.
Rather than pretend that money does not exist, it records an opening balance for the eBay Receivable account, anchored to the balance eBay itself reports at that moment. So your books start by agreeing with eBay's own figure, on day one, instead of drifting until someone investigates.
