An expense tracker for organisations. A Flutter app for members, a web panel for administrators and a FastAPI server that forecasts next month's spending and shows how accurate it was. Showcase with fictional data.
Spending, predicted
What it does
- A Flutter app for members, a web panel for administrators, and a platform owner who creates organisations, all on one API.
- Next month's spending is forecast per category, tested on past months, and the error is shown next to the number.
- The category is suggested from the expense title while you type, with accuracy measured on titles the model had never seen.
- A recorded expense can only be changed or removed after the administrator approves a request.
- 140 backend tests, 24 app tests and 42 browser checks, including a test that script injected through an expense title does not run.
- All organisations, people and amounts are invented sample data.
