Record who actually paid.
For every expense, write down the full amount, currency, date, payer, and the people who benefited. Add the receipt if you have one. A planned quote belongs in the plan until someone actually pays it. If Sherif pays $240 for a boat shared by four people, each share is $60. Sherif covered his own $60 and is owed $180 by the other three.
Use the split that fits that expense.
Equal shares work for a boat everyone used. Accommodation may need nights: a $1,200 stay shared by two people for two nights and one person for one night has five person-nights. Their shares are $480, $480, and $240. Fuel may be shared only by the named passengers in that car. Do not apply the accommodation rule to groceries.
Show paid, owed, and already repaid separately.
If a traveler’s $60 boat share was already repaid, their open boat balance is zero. If the group later corrects the split to $50, that $60 payment remains in the history and the extra $10 becomes credit. Rewriting the payment to match the new share would hide money that actually moved.
Check that every cent is accounted for.
For each expense, the shares must add to the original amount. Across the trip, everyone’s net balance must sum to zero. A useful personal report lists each purchase, its split rule, your share, what you already sent, and what remains. That makes a dispute about one purchase possible to resolve without guessing from a single total.
