I wrote a made-up October bank statement for a solo baker selling at a weekend market (fixtures/marketvendor-checking.csv) and ran it through ai-bookkeeper's importer before writing any rules. Of 17 lines, 14 got an account: Square deposits, Restaurant Depot, the market fee and the cottage-food permit were already covered. GFS and a Sam's Club ingredient buy were not.
I added one built-in rule for wholesale food-service stores, baking ingredients and packaging (supplies). Now 16 of 17 get an account. The Venmo cash-out is deliberately left in review: it could be a customer, a friend or the baker's own money coming back.
The page shows the month: $1,998.65 in, $1,013.79 out, $984.86 profit. A test pins the accounts and the sums.
The rules came from store names, not a real vendor's export, and were tuned on this one fixture, so read "16 of 17" as the fixture passing, not an accuracy figure. Whether ingredients belong in cost of goods sold or supplies is left to the baker's accountant. A real export is still what the project needs.
