Use item logic before payment logic
Most bill conflicts happen because the group starts collecting money before agreeing on who consumed what. Confirm participant scope first, then calculate.
If items are strongly unequal, use weighted entries instead of equal split assumptions.
Handle service charges and tax correctly
Restaurant receipts can include service charge, VAT, or platform delivery fees. These amounts should be included in the final total before deciding transfers.
If a tip is voluntary and only one person offered it, agree on whether it is shared or personal before final settlement.
- Do not round each person early.
- Round only the final transfer amount.
- Keep a receipt screenshot until everyone confirms.
Finance safety checks
Before requesting payment, re-check payer names, currency, and transfer method. Cross-currency mistakes are common in mixed USD/KHR groups.
The calculator provides educational math support. Final payment responsibility remains with the group.
