Frequently asked questions
▸Can more than one person pay for an expense?
Yes — each expense can have multiple payers with amounts, and the cost is divided across selected members either equally or by custom weight (unequal shares).
▸What is a minimal settle-up plan?
After netting everyone's balance, the tool suggests the fewest bank transfers needed so every member comes out even — usually far fewer payments than paying each other back pairwise.
▸Can I export the expenses?
Yes — copy a CSV of all expenses and balances to your clipboard for pasting into any spreadsheet. Everything is computed locally.
