Who pays whom
Get even in a few payments
After our ski weekend, all five of us had paid for something. Leo booked the cabin, Ana got the lift passes, Sam did the groceries and I covered two dinners.
Then came the math. Who pays whom? A dozen little transfers flying around the group chat, and someone always pays the wrong person.

In The One Bill, the Settle tab turns everyone's balance into a short list of payments. It pairs the biggest debts first, so just a few transfers get everybody even.
Leo tapped Copy and pasted the list in the chat: who pays whom, and how much. When someone paid, we recorded it on the bill, even when it was only part of it.
The One Bill never touches the money. Pay back however your group likes, and the bill shows All even when nobody owes a thing.
