Choosing your currency.

EUR by default. When you should change it, and what gets reformatted across the app when you do.

One currency per business. Currency is set at the business level, not per location. If you genuinely run two shops in different currencies, you need two nouz accounts — for now.

Currency is one of those settings that's a one-line change with implications across every screen — the symbol, the decimal format, the thousands separator all flip together. Worth getting right once at signup so you don't spend three months reading numbers wrong.

01 Why EUR is the default

We're built in Vienna and most of our owners run shops across the Eurozone. EUR is the default for new accounts, with the German number format (€1.234,56) — dot for thousands, comma for decimals. That matches how German, Austrian, Swiss, Italian, French, Spanish and Dutch owners actually write money down.

If your shop is in the Eurozone and you read numbers in the German format, you're probably fine with the default — nothing to change.

02 When to change it

The currency on Settings → Business profile should match the currency your bank deposits land in. Common cases for changing:

  • UK shop. Change to GBP — switches the symbol to £ and the format to £1,234.56.
  • Swiss shop billing in CHF. Change to CHF.
  • Polish shop. PLN, with as the suffix.
  • Nordic shop. SEK / NOK / DKK depending on country.

03 What changes when you do

Switching currency is one click. Every monetary display in the app reformats:

  • Symbol — €, £, $, CHF, zł, kr.
  • Decimal separator — comma for European, dot for British/American.
  • Thousands separator — dot for European, comma for British/American, space for some Nordic.
  • Symbol placement — prefix for most, suffix for PLN and some Nordic.

The formatter is automatic — you don't need to configure separators manually. Pick the currency, the format follows.

04 Historical entries

Historical entries don't convert. Switching from EUR to GBP doesn't convert your old €5.400 of revenue into £4.750. The number 5400 stays the number 5400 — only the symbol changes. If you genuinely change currencies, export your old data first.

This is a deliberate decision — live forex conversion of historical numbers would be confusing and would never match what was actually deposited at the time. The clean pattern: export old data in the original currency, then switch.
