Set your base currency
and how it shows everywhere.

Currency in nouz is one of those settings you touch once at signup and never think about again. The choice you make controls not just which symbol prints next to every number (€ vs $ vs £), but also the decimal and thousands separators the formatter uses, and which currency Stripe bills you in.

01 The default

New nouz accounts default to EUR with the German / European number format: €1.234,56 (dot for thousands, comma for decimals). That matches the country defaults for most of Western Europe and lines up with how owner-operators here actually read numbers.

If your country defaulted to EUR at signup, you're probably good — no need to change anything. If you signed up from a UK / US / Polish / Nordic shop, you'll want to switch.

02 Where to change it

Open Settings → Business profile. The currency picker is right under the business name. We support the major currencies — EUR, USD, GBP, CHF, SEK, NOK, DKK, PLN — and the formatter picks the right separators automatically based on which you choose.

Pick the currency and click Save. A green toast confirms. The whole app reformats within a second — go check the Home tile to see the new symbol.

03 What changes when you do

• Every monetary display. Home tile, P&L lines, Statistics waterfall, exports, related cards — everything.
• The symbol. Switching to USD shows $ instead of €; switching to GBP shows £; switching to PLN shows zł as a suffix.
• The separator format. US English uses $1,234.56 (comma for thousands, dot for decimals). German uses €1.234,56. Polish uses 1234,56 zł. We pick the right one automatically.
• Stripe billing. Your next invoice will display in the new currency. Stripe handles the conversion if you switch — though we don't recommend switching mid-subscription unless you're also genuinely changing the bank you deposit into.

04 Historical entries

Here's the important caveat: switching currency doesn't do a live forex conversion on old data. The number 1500.00 stays the number 1500.00 — only the symbol changes. €1.500 on Tuesday becomes $1.500 on Wednesday if you switch, but Tuesday's real revenue was 1500 of whatever you were using on Tuesday — not the converted amount.

For most owners this is a non-issue (you set currency once at signup and never change it). If you genuinely move currencies — say, you change the bank you deposit into and switch reporting — export your old data first so you have a record of the original numbers in their original currency.
