Invoice tax numbers and billing address

Adding tax numbers and billing address

Add your company's VAT number, tax ID, or billing address to invoices.

Adding a VAT number (European Union)

1. Go to Billing in the sidebar.
2. Click Manage subscription (Stripe customer portal).
3. Click Billing information or Tax details.
4. Enter your VAT number (e.g., EU123456789).
5. Stripe validates the VAT number format. If valid, invoices will show 0% VAT (reverse charge).
6. If validation fails, standard VAT rate applies.

Adding a tax ID (non‑EU)

1. In Stripe customer portal → Billing information.
2. Enter your Tax ID (e.g., US EIN, Australian ABN, Canadian GST/HST).
3. Select the tax type from the dropdown.
4. Save changes. The tax ID appears on future invoices.

Updating billing address

1. In Stripe customer portal → Billing information.
2. Edit your address: street, city, postal code, country.
3. Save changes.
4. Past invoices are not retroactively updated. Only future invoices use the new address.

Correcting past invoices

1. Update your tax details as above.
2. Contact billing@certorix.com with invoice number(s).
3. We will issue a credit note and a corrected invoice within 5 business days.
