The problem
The client was tracking revenue and expenses by hand — written records with no running picture of the business. At the end of each month, someone had to manually total everything to work out whether they'd made a profit or a loss. It worked, but it was slow, error-prone, and told them nothing until the month was already over.
Decisions that mattered
Optimized for zero training time
The interface was built around one core loop: log an entry, watch the number move. No accounting jargon, no configuration screens, no step the client had to think twice about. If a feature required an explanation, it was cut or simplified until it didn't.
Real-time P&L, not month-end math
Instead of totaling figures manually at month close, the app calculates profit and loss continuously as entries are logged — so the client sees where they stand at any point, not just in arrears.
The outcome
Manual, handwritten logging was eliminated entirely. The client no longer spends time at month-end reconciling paper records — the number is already there. The time saved compounds every single month.
