> Update legal name, tax ID (NIF/CIF), address, and billing email so your next invoices come out right. Invoices already issued do not change.

Your enisa.ai billing details — legal name, tax ID (NIF/CIF), address and billing email — are changed under **Settings → My account → Billing**. By the end, your next invoices will carry the correct details — what your accountant needs to book them without trouble.

Invoices are issued by Stripe, our payment provider, using the details you save here. That is why this change applies to **future** invoices: an invoice already issued is a closed fiscal document and cannot be modified.

## Steps

1. Go to **app.enisa.ai → Settings → My account → Billing** (visible to the owner and admins).
2. Open the **Billing details** tab.
3. Fill in or correct: legal name, **NIF / CIF** (Spanish tax ID), billing email, address, city, and postal code.
4. Click **Save details**. The change is saved to your account and updated in Stripe in the same operation.

Two details that prevent headaches later:

- **We validate the tax ID check digit before saving.** A mistyped NIF produces an invoice your accountant rejects months later; we would rather warn you on the spot.
- **The country is changed under "Account details"**, not here, because it also determines which tax rules apply (for example, 21% VAT in Spain).

## Common issues

### What if the tax ID could not be saved?

Check the control digit: it is the most common error. If you are sure the number is correct and it still fails, write to hola@enisa.ai.

### What does the warning "Stripe has different details" mean?

We saved your copy but the sync with Stripe did not complete, and Stripe is who prints the invoice. Click **Save details** again to retry.

### What if I need to correct an invoice that was already issued?

Issued invoices cannot be edited. Write to hola@enisa.ai with the invoice number and the detail to correct, and we will handle it with a corrective invoice where applicable.

### What if I can't see the Billing section?

Your role is member; billing belongs to the account owner and admins.
