Oja Ledger: Talk your sales. We write the book.

I grew up around Nigerian markets. My mum's friends sell provisions, rice, yam, Milo, Indomie, and almost all of them keep their books in their heads or in a torn exercise book. At the end of the day nobody knows exactly how much came in, who still owes, or that the Peak milk finished two days ago. Debts get forgotten. Stock runs out without warning. Money leaks.

Oja ("market" in Yoruba) Ledger fixes that with the one thing every trader already does all day: talk.

What it does:
- Book: tap the mic and say it the way you'd say it in the market, English or Pidgin. "I sell 3 tubers of yam 2k each." "Mama Ngozi go pay 3k Friday for rice." Meta's Muse reads it, works out if it's a sale, a purchase or a debt, and shows a simple confirm card. One tap and it's in the book.
- Debts: anyone who owes gets a one-tap WhatsApp reminder with the amount, so mama doesn't have to chase people.
- Mama's Shelf: snap a product and Muse names it. You set your own price once, and stock counts itself down every time you sell.
- Price Scan: point the camera at a product on your shelf and your own price pops up. Tap Sell 1 and it's booked. No typing, no searching. You can also search the shelf by name.
- Today's money: sold, bought and owed totals, plus low-stock warnings before things finish.
- WhatsApp price list: send your whole shelf with prices to customers in one tap.

It's a phone-first web app that installs from the browser, works on cheap Android phones, and keeps everything on the trader's own phone. If the network drops, a built-in offline reader still books simple sales so the market never stops. Every trader keeps her own prices; there's no shared price board telling her what to charge.
