Per-bill splits — proportional, custom %, or even.
In short
Open the bill detail drawer → Splits tab. Pick a rule (even / custom / proportional). The settle-up tracker updates automatically when payments log.
Three split modes
Even — total / number of members.
Custom % — you set each member's share, must sum to 100%.
Proportional — by income (set under Settings → Income for each member).
How settle-up math works
When a payment logs, the payer is credited the full amount. The split assigns "owed" amounts to each member. The settle-up tracker sums the net (paid - owed) per member across all bills and tells you who owes whom.
Splits are per-payment, not per-bill-definition. If you change the split rule, only future payments use the new rule. Past payments keep their original split.
