Common mistakes
- Forgetting to separate items some people did not consume, such as desserts, drinks, or add-ons.
- Splitting VAT and service equally even when food totals differ a lot.
- Not marking who paid up front, which causes the reimbursement summary to point to the wrong person.
Tips for faster bill splitting
- Add everyone first, then enter receipt items to reduce backtracking.
- Use the duplicate action when your receipt has several similar lines.
- Combine quantity with split weights when one item has uneven portions.
