Tips
- All expense features require a Pro subscription
- Use “Save & Add Another” when recording multiple expenses at once — faster than opening the form repeatedly
- Duplicate expenses are useful for recurring expenses (e.g., monthly electricity) — duplicate then change the amount and date
- Custom categories are great for specific needs not covered by built-in categories
- Data updates automatically in reports — every expense you record immediately appears in the Report Overview
