# I would like to change the billing data on my invoice

Canonical URL: https://support.optimonk.com/en/articles/i-would-like-to-change-the-billing-data-on-my-invoice

Your company name, address and VAT number are yours to edit — you don't need to write to us. Update them once, and every invoice issued from then on carries the new details.

**Only account Owners can edit billing data**; the Billing tab is hidden for members.

## Update your billing details

1. Click your **name** at the bottom of the left sidebar and choose **Settings**.
2. Open the **Billing** tab. The first section is **Billing address**.
3. Fill in the fields:

- **First name ***
- **Last name ***
- **Company name**
- **Street address ***
- **City ***
- **Postal code ***
- **Country ***
- **EU VAT number**

The fields marked with * are required; if one is empty the form says *Please fill in all required fields.*
4. Click **Save billing address**. You'll see *Billing address saved.*

That's all — your next invoice uses the new data.

Tip: if you are a VAT-registered company inside the EU, fill in the **EU VAT number** field. It is used when your invoice is calculated, so it is worth setting before your next payment rather than after.

## An invoice that has already been issued

We cannot rewrite an invoice that is already out. If the details were wrong on one you have received, send us the **Order** number from **Settings → Billing → Invoice history** at **support@optimonk.com** (or start a live chat), tell us what should be on it, and we will issue the corrected invoice for you.
