Tips and service charge are often the messy part
Many groups can agree on food costs but still get stuck on how to split gratuity, service fees, or bar tabs.
HarnDuay makes the logic visible before anyone pays.
Useful for restaurants, bars, and celebrations
If some people ordered cocktails or a venue added service charge automatically, HarnDuay keeps the final split transparent.
That makes it useful for office dinners, parties, birthdays, and late-night group bills.
How to split tips and service charge fairly
- Add everyone and the actual items ordered.
- Turn on the 10% service charge to apply it across the bill.
- To add a tip, enter it as an item and choose who shares it.
- Confirm the tip is split the way the group agreed.
- Share the summary before anyone pays.
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.
