# Billing details and VAT

Set the billing name, email, address and VAT number used for your invoices.

Owners and admins can edit billing details in Billing → Edit billing details. They're saved to your billing profile and appear on invoices issued from then on. Changes are recorded in the audit log.

## VAT numbers

Enter the number with its country prefix, for example GB123456789 or IE1234567T. Spaces, dots and dashes are removed. The prefix must match the billing country: Greece uses EL, and UK businesses can also use an XI (Northern Ireland) number. UK, EU, Swiss (CHE) and Norwegian numbers are accepted.

## How VAT is charged

Prices exclude VAT. Where tax applies, it's calculated at checkout from your billing address and VAT number and shown on the invoice, including reverse charge for eligible business customers.

## Past invoices

Changing details doesn't alter invoices that were already issued. Contact support if one needs reissuing.
