Feirin

Feirin organizes the work of people who make and sell at markets, with no spreadsheets and no mental arithmetic. Products with cost per ingredient, yield, packaging and the margin worked out for you. Stock of both raw ingredients and finished goods, with purchases and losses logged by typing or speaking. An open market day with sales in a few taps — instant transfer, cash or card — and the till closed at the end of the day. A dashboard with sales, expenses, losses and the estimated result of each market day, comparing periods.

The assistant knows the stock, the prices and the sales in your own account: it answers "how much cocoa do I have?" or "which market made the most profit?" right away, by text or by voice, and shows what it understood before recording any purchase, loss or new price. It runs in the phone browser and can sit on the home screen like an app, with a light theme for the sun of the market and a dark one for baking through the night.
