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 is EUR the default currency?
EUR is the default for new accounts because nouz is built in Vienna and many of our owners run shops across the Eurozone. New accounts start in EUR with the German number format (€1.234,56) — dot for thousands, comma for decimals — which 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 that way, the default is probably right and there's nothing to change.
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 should I change my currency?
Change your currency when the default doesn't match the currency your bank deposits actually land in. The currency on Settings → Business profile should mirror your bank. Common cases include a UK shop switching to GBP, a Swiss shop billing in CHF, a Polish shop using PLN, or a Nordic shop on SEK, NOK, or DKK depending on country. Setting it correctly once flips the symbol and number format everywhere. The list below covers the common cases.

03 What changes when I switch currency?
Switching currency is one click, and every monetary display in the app reformats automatically. The currency symbol changes (€, £, $, CHF, zł, kr), along with the decimal separator (comma for European, dot for British/American), the thousands separator (dot, comma, or a space for some Nordic currencies), and the symbol placement (prefix for most, suffix for PLN and some Nordic). You don't configure separators by hand — pick the currency and the format follows. The list below shows each.
- 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 Do my old entries convert when I change currency?
No — historical entries don't convert when you switch currency. The number 5400 stays 5400; only the symbol changes, so old €5.400 of revenue simply reads as £5.400. This is deliberate: live forex conversion of past numbers would be confusing and would never match what was actually deposited at the time. The clean pattern is to export your old data in the original currency first, then switch.
