A shared space where everyone sees the group's money and nothing of yours. Split what was spent, settle in the fewest payments, and keep the receipts attached.

Orla computes the shortest set of transfers that clears every balance, and a pay link closes each one.
Three payments instead of nine. Each one carries a pay link with the exact amount, and the debt closes itself when the money lands.
Shared cash with its own treasurer. Ask everyone to chip in, spend from it, and the balance stays visible to all.
Invite the group with one link. Friends without an account join as guests, hold shares and appear in every split. When they sign up, they claim their history.

Rent, internet and the storage unit book themselves on the same day every month and split the way you set once. The trip ends with a summary PDF everyone can keep.
