Group trips are the classic place where money gets messy. One person books the apartment, another covers the train tickets, someone else buys groceries, and by the last day nobody is sure who owes what. A little structure while you travel saves a lot of awkward conversations afterwards.

1. Make one shared group before you leave

Create a group for the trip and invite everyone who is going. In ScratchSplit, groups are invite-only: friends join with a link or a QR code, so the trip's spending stays between the people on it.

2. Record expenses as they happen

The easiest trip ledger is the one updated on the spot. Add each cost with who paid and who it was for: the apartment, fuel, museum tickets, the late-night pizza. It takes seconds, and nothing gets forgotten.

3. Pick the right split for each cost

ScratchSplit stores every amount as whole cents. When a bill does not divide cleanly, the leftover cents are assigned so the shares always add back up to the exact total.

4. Settle up with the fewest payments

At the end of the trip, look at net balances instead of individual IOUs. ScratchSplit nets out who owes whom across the whole group and suggests the fewest payments that clear everything. Pay each other however you normally do, then record the settlement in the app.
