Everyone pays for what they had. Exactly.

How Outzu works it out

1. Your items. Everything you tap is yours.
2. Shared items. A dish tapped by three people is split three ways. You can set portions too — say you had two of the five dumplings.
3. Service, tip and discounts. These are shared in proportion to what each person ordered. Order more, pay a bigger share of the service; skip the wine, pay no service on it.
4. The odd amounts. ¥2,100 between three people doesn’t always divide exactly. Outzu hands out what’s left over fairly, so the shares always add up to the exact total on the receipt — never more or less.

A worked example

Four friends, ¥19,050 of food, 12.5% service (¥2,381), ¥21,431 in total. Ali paid.

The four shares add up to ¥21,431 exactly. Sara, Priya and Tom each get one payment to make, with Ali’s details and a reference.

Paying back

Outzu never holds your money. You pay your friend directly — bank transfer, IBAN, or the payment app they prefer — and tap “I’ve paid”. They tap “Received”, and when everyone has, the bill is settled. Got cash? There’s a button for that too.
