For colivers and travelers

Who paid what. Split between people. Settled in the fewest transfers

Rua Augusta 14 is a flat shared by four people and a guest who stays over, with a weekend in Porto paid from a kitty.

Settled in the fewest transfers, trip by trip

Balances that clear everyone in the shortest set of transfers, and every trip kept apart from the others.

The fewest transfers that clear everyone

Four people, twenty-nine expenses, one guest. Who owes whom, and how many transfers does it take to square the flat?

A kitty expense creates no debt: the money was everyone's before it was spent

A kitty for the weekend away

Money everyone chipped in, spent by one person: a kitty expense creates no debt, because the money was everyone's before it was spent.

Who does what

Four flatmates and a guest

Owner
Opened the group, holds the kitty, and adds the guest by name.
Member
Adds what they paid, sees the group's money and nothing of anyone's own.
Guest
Holds shares and chips in without an account, and claims the row when they join.

Control and trust

The flat sees only the flat's money

Nothing of yours
Everyone sees the group's money and nothing of anyone's own space; a personal space stays invisible to the whole flat, always.
Guests
A guest holds shares and chips in without an account; when they join, their row is merged into them.
Fewest transfers
The settle-up is the shortest set of transfers that clears every balance, recomputed on each expense.
The receipt stays
A photographed receipt stays attached to the expense, so the argument is settled by the photo.

Questions

The questions that come first

Does everyone in the flat need an account?

No. A guest is added by name, holds shares and chips in like anyone else. When they join by invite, their row is merged into their account with every share they held.

Can we add an expense from the group chat?

Yes. In Telegram or WhatsApp, a message like "I paid 32 for the taxi, me, Sofia and Ana were in it" becomes a draft with the split; a name the bot does not recognise becomes a question, never a silent guess, and nothing is written until you confirm.

What happens when someone pays their share?

The person marks the transfer settled, or the payment lands by link and closes the debt itself. A repayment marked by mistake can be undone.
