Sankhya+
A WhatsApp payment ledger for small traders that refuses to guess.
Small shops in India take orders and payment promises over WhatsApp but keep no ledger, so dues get forgotten and disputes come down to memory. Sankhya+ reads an exported chat and returns who owes what, with the original message attached to every entry.
- Never invents an amount. An order with no agreed price is flagged, not filled in.
- Every entry carries its source message, so a dispute has a receipt.
- Runs offline from a single file on a mid-range phone.
- Works in English, Hindi, Kannada and Malayalam, including romanised typing.
32 of 32 automated tests pass on the four trap cases: price haggling, unpriced orders, double-counted payments and future orders.
