AI Bookkeeper could already read eBay's Seller Hub transaction report; it had no page a seller could find. There is one now: eBay bookkeeping.
The worked month is a hand-made fixture. Two orders ($145.00 with shipping), a $10.00 refund, $20.10 of final value fees, an $8.20 label and $5.00 of sales tax eBay collected net to a $111.70 payout. Booked from the bank line, income is $111.70 and expenses are zero. Booked from the report, income is $135.00, costs are $28.30, and the tax stays out of income. Profit is the same $106.70 either way; the difference shows up against a 1099-K and on Schedule C. An unpaid third order is listed as pending.
A test pins every figure on the page to the parser's output. The layout is from memory of eBay's help pages; no real export has been tried, and the page says so. Not tax advice.
