Group trip budget: how to stop one person paying for everything
The trip gets planned. The budget does not. The result is one person putting down €1,400 six months out, and nobody knowing where things stand on departure day.

There is always someone who books. Usually the same person, the organised one, and they are the one who fronts the deposit on the house, sometimes the flights, sometimes both. Six months later they are carrying €1,400 on behalf of eight people and cannot bring themselves to chase anyone.
Everything else follows the same slope: the first tank of fuel, the first food shop, dinner on the night you arrive. By the end of the week three people have paid for everything and five have a vague sense of being in debt.
This is fixed by three decisions taken before you leave, and they take ten minutes.
Decide first: three questions, three answers
1. What counts as shared? Write it down, even in one line. Accommodation, breakfast supplies, fuel and tolls: yes. Souvenirs, late-night cocktails, the paragliding trip three people are doing: no. That is not meanness, it is what stops a couple who do not drink paying part of the bar.
2. Who fronts what? Spread the big lines across several people rather than leaving them all on one. Four people fronting €350 each have a much better time than one person fronting €1,400. The final tally is identical; the stress is not.
3. How do we split? Equal shares by default, with two exceptions to settle right away: children, often at half a share, and unequal rooms, because a suite with a view is not a sofa bed. A key agreed beforehand gets accepted; the same key proposed on the last night is a negotiation.
The deposit, the line that poisons everything
A deposit paid six months out is unlike anything that follows. It is large, it is old, and the person who paid it eventually stops knowing whether they got it back.
Two ways to neutralise it:
- split it up front: everyone sends their share to whoever booked, within the month. That is the cleanest option, and it also settles the commitment question: someone who has paid €180 rarely drops out three weeks before;
- record it as a group expense on the day it is paid, with its real date. It then shows up in the tally like everything else, and the person who fronted it gets the credit on their balance.
The worst option is leaving it out of the tally "because we'll sort that separately". That is precisely what nobody will remember.
While you are there: record now, not tonight
One rule for the whole trip, and it beats every method: record the expense in the supermarket car park, not on the way home, not that evening, not on Sunday.
Three reasons, in order of importance:
- the exact amount is still in front of you, on the receipt;
- you still remember who it concerned, which is the only genuinely perishable piece of information;
- if nobody else records anything, you become the group's accountant, and that is a role you never get to hand back.
Worth a line: accommodation, food shops, fuel and tolls, shared restaurant bills, entry fees and activities done together, taxis. Not worth a line: coffees, ice creams, anything under a few euros. Set a threshold and stop discussing it.
Paying in another currency
This is the case that breaks almost every improvised tally: you count in euros and pay in baht, dirhams or zloty.
The right method is one sentence: the expense is converted once, when you record it, and the rate never moves again. A 2,400 baht bill paid on 12 July is worth what it was worth on 12 July. Fetching today's rate would change everyone's balance every morning, three months after you got home, without a single expense having changed.
Two practical points:
- record the amount in the currency on the receipt, and let the conversion happen. That is what you can see, and what you will be able to reconcile against your statement;
- use your card's rate, not the central bank's. They are never the same, and the card's is the one you actually pay. A single figure, entered once for the trip, is enough.
Getting home: settle in two or three transfers
On the last evening or the day after you get back, never later. Three weeks on, the mood has changed and nobody wants to reopen it.
The right way to present it is not "who owes what to whom for each expense" but one balance per person, then the list of transfers. For eight people you never need more than seven transfers, and in practice three or four do it.
Send the full tally to everyone, not just the amounts due. A figure without its detail gets challenged; a table where each person can find their own line almost never does.
With Kotisso
Kotisso was built for exactly that moment: an expense recorded standing up, one hand full, in a supermarket car park abroad.
What helps most on a trip:
- foreign currency: the expense is entered in baht, the rate is entered once, and nothing downstream knows it was paid elsewhere. Balances, totals and the settlement plan stay in the group's currency;
- per-expense participants: Tuesday's restaurant only lands on the four people who were there. Untick, and the balances follow immediately;
- a photo of the receipt, attached to the expense, for the rare occasions when someone wants to check;
- the exported tally, as a spreadsheet or a PDF, to send round on the way home. Every row sums to zero and each person's column sums to their balance, so there is nothing left to explain.
The whole tally is free, including currency conversion, receipts and export. There is no bank account to connect, which matters when you are sharing a trip and not your statements.
Common questions
Does everyone need to sign up? It is better, because each person then sees their balance without asking and can record their own expenses. But one person can enter everything for the group and share the exported tally at the end.
How do we handle children? Usually at half a share for accommodation and meals, and out of the tally for anything that does not concern them. Decide it beforehand, write it down, and do not revisit it.
What about a cash kitty? It works for small day-to-day spending, as long as you record what each person put in. The kitty is then just another participant: contributions are amounts fronted, and what it pays for is charged to everyone.
What do we do with the rental deposit? It is not an expense, it is money tied up. Keep it out of the tally, note it separately, and only count whatever is not returned.
