About this tool

Kotisso keeps the books for any group that shares money. Everyone records what they paid and how it splits: equally, by shares, by exact amounts or by percentage. Balances stay up to date for all members at once, their sum is always exactly zero, and when it is time to settle Kotisso proposes the shortest set of transfers. The accounting is free and stays complete: a free account sees fewer lines in the feed, never different figures, and CSV and PDF exports are free too. No bank connection, no money moved, no ads. Sixteen languages. For flatshares, group trips and separated parents.
