What it does

  • ✓ Who owes you and who you owe, both sides, with the net position.
  • ✓ Every entry dated and never secretly changed — the dispute is over when you show the record.
  • ✓ Late debts flagged by themselves; a polite WhatsApp or SMS reminder with the exact amount in one tap.
  • ✓ Grows into the full till, stock and books in the same account when you are ready.

Works offline where it matters · your own name and logo on everything · mobile money built in · every figure lands in the books.
