Billy the Split

Notes

We build an app for splitting group expenses, which means we spend a lot of time looking at the part of a trip nobody writes guides about: who paid, who owes, and why that gets tense on day four. These are the things worth knowing before you go somewhere with five other people.

Who books the house

Booking anything for six people

Timed entry punishes groups more than anyone. How to buy six tickets in March without one person quietly eating the no-shows in June.

When someone gets hurt on the trip

A twisted ankle is a medical question for ten minutes and a money question for the rest of the week. What the group ends up splitting, and the boring conversation to have first.
