Spendthrift Spendthrift

Settle up, and why six debts become two.

Settling up means recording that money has actually changed hands, so the ledger matches reality. Behind it sits a small, useful piece of arithmetic, debt simplification, that turns a group's tangle of individual debts into the fewest payments needed.

What settle up actually does.

A splitting app tracks who owes whom as bills come in. Settling up is the separate step of recording that a specific amount has actually been paid, outside the app, a bank transfer, cash, a payment app. Spendthrift never touches anyone's money itself: settling up opens your own payment app with the amount and the person already filled in, and records the outcome once it happens. Nobody's funds pass through Spendthrift at any point.

Debt simplification, in one example.

Four people can rack up six separate debts across a month of shared bills. Simplified, the same net outcome, who ends up with how much, often takes only two payments. The arithmetic finds who owes the most overall and who is owed the most overall, and matches them first, repeating until everyone nets to zero.

What settling up actually lets you do.

Three requested behaviours

Pay off one specific expense rather than a netted balance, pay part of what is owed without the rest being wiped away, and settle without Spendthrift ever holding the money.

PAY OFF ONE EXPENSE, NOT A NETTED BALANCE YOU OWE VIKRAM ₹4,000 Cab to the airport ₹1,600 paying this one Dinner, four of us ₹1,200 Groceries ₹1,200 Left after it clears ₹2,400 Asked for since 2012. It settles the expense you actually paid for, and says so in the record.

Pay off one expense, not a netted balance.

Owe four thousand across three expenses and pay the cab fare alone. The balance drops to what is left, and the record says which expense cleared.

HALF NOW, HALF LATER Paid now ₹1,000 Still owed ₹1,400 of ₹2,400 The balance is not zeroed because money moved. It is reduced by what moved. Both of you confirm the amount, so neither of you is trusting a button. The remainder stays attached to the expenses it came from. A settlement that zeroes a balance whether or not the money arrived is a lie in the ledger.

Half now, half later.

Pay part of a balance and the rest stays owed, still attached to the expenses it came from.

WE NEVER TOUCH THE MONEY Your app opens with the amount and the payee filled in Their bank the money goes straight there Spendthrift is not on this path Both of you mark it paid, so the record needs no trust in either direction. We hold no float, so nothing is ever held for three days and nothing can be reversed by us.

We never touch the money.

Settling opens your own payment app with the amount and the payee already filled in. The money goes from your bank to theirs, and both of you confirm it.

Priya, Rohan, Meera and Aditi share a month of bills between them. Simplified, two payments settle the whole group, and Aditi's debt is kept honestly, not dropped, because she has no app installed. See the full diagram.

Try it with your own group.

The group expense calculator runs the same simplification on whatever expenses you enter, for a trip or a shared flat, and shows the fewest payments that settle the group. Nothing typed there is sent anywhere.

Questions.

What does settle up mean

Recording that a debt between two people has actually been paid, outside the app, so the ledger matches reality. The app tracks who owes whom; settling up is marking that a specific amount has changed hands.

What is debt simplification

Reducing a group's tangle of individual debts to the fewest payments that produce the same result. Four people with six separate debts between them often only need two payments to leave everyone exactly settled.

Does the app move the money itself

No. Spendthrift never touches anyone's money. Settling up opens your own payment app with the details already filled in, and records the outcome once it happens.

What if someone in the group does not have the app

Their share is still tracked and shown, labelled as still owed, never silently dropped, so the ledger stays honest even when it cannot be simplified through every member of the group.

See the Splitwise alternative comparison for how this fits against the app most people already know, or group expenses to try it now.
