Open Settings → Localisation.
What to set
- Country — where the business is registered; seeds sensible defaults elsewhere.
- Base currency — any currency; amounts always carry a currency (an amount without one is treated as a bug).
- Timezone — reminder send windows and quiet hours are evaluated here.
- Date format — how dates render in the product; samples match the format you pick.
- Save settings.
After you save
- New timing and quiet-hour checks use the updated timezone.
- Currency display for balances follows the base currency you chose; multi-currency invoices still keep their own currency codes.
What this will not do
- It will not auto-convert foreign invoices into your base currency for chasing math.
- It will not turn text messaging on for a territory — texts are not a customer product at launch.
