Challenges
- 01Personal and business money get mixed, so small business owners struggle to tell whether the business makes a profit.
- 02Notebooks and spreadsheets rarely get filled in because it is a hassle, especially on a phone.
- 03The recorded balance often does not match the bank balance, and the difference is hard to find.
Solutions
- 01Two separate books (Personal and Business) with a combined view; transfers between books are never counted twice.
- 02One transaction is logged from a phone in seconds: amount, category, description, and the time fills in automatically.
- 03All amounts are whole rupiah and traceable to their transactions, so they are easy to match against the bank account.
