Summary
When to use a split bill calculator
A simple equal split is often unfair when a group orders different dishes, drinks, or extras. HarnDuay lets you assign each item to the people who actually shared it.
That makes it useful for team lunches, family dinners, birthday meals, and any situation where one person pays first and everyone settles later.
Why HarnDuay works better than a note app
Instead of manually typing amounts into chat, you can build the bill item by item, add VAT or service charge, and get a clean final summary.
The result is easier to verify, easier to share, and more accurate when groups are large.
How to split a restaurant bill with HarnDuay, step by step
- Add everyone at the table in the People section.
- Add each dish with its price in the Items section.
- Choose who paid for each item and select only the people who shared it.
- Turn on VAT 7% or service charge 10% if the restaurant adds them.
- Review the per-person totals and who-owes-whom, then share the link.
Example: splitting a bill for 3 people
- A paid 900 THB for food everyone shared → 300 THB each.
- B added drinks of 120 THB shared by B and C → 60 THB each.
- HarnDuay nets it out and shows exactly how much each person owes A.
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.
