# Modify name, tax ID, or address on an issued invoice

> How to change the invoiced customer's data, and when updating the contact is enough vs when a corrective is needed.

## Two paths depending on what changes

If you need to change **the customer's data** (legal name, tax ID, address), updating the contact is usually enough and the invoice refreshes by itself.

If you need to change **the reservation's data** (dates, different billable customer, add or remove lines), a **corrective** has to be issued.

## Change the invoiced customer's name / tax ID / address

<Steps>
  <Step title="Open the contact record">
    Left side menu → **Contacts** → find the company or customer that shows on the invoice.
  </Step>

  <Step title="Update the data">
    Edit the name, tax ID, address, or whatever needs changing. Save. **The data updates automatically on the invoice.**
  </Step>

  <Step title="Verify the invoice">
    Go back to the reservation → **Invoicing** section → confirm the data has been picked up correctly.
  </Step>

  <Step title="If it didn't refresh on its own, force it">
    Inside Invoicing, click **Modify** on the invoice line → remove the linked contact and search for it again. On save, it updates.
  </Step>
</Steps>

<Note>
  Changing the **address**? To bill to an address different from the guest's check-in one **without overwriting it**, see [Bill to an address different from the check-in one](/en/invoicing/billing-address).
</Note>

<Tip>
  Once the contact is updated, you can resend the invoice to the customer using the **Send by email** button on the invoice itself.
</Tip>

## When a corrective is needed instead

If what changes isn't contact data but the reservation itself — dates, a different billable customer, add or remove lines — a corrective has to be issued. See [Correct an invoice](/en/invoicing/correct-invoice).

## Special cases

<AccordionGroup>
  <Accordion title="VeriFactu active and the invoice is older than 48 h">
    Don't touch the validated invoice — **always corrective**. The fiscal numbering is already sent to the tax authority; modifying data without a corrective opens a compliance issue. See [Correct an invoice](/en/invoicing/correct-invoice).
  </Accordion>

  <Accordion title="VeriFactu isn't active and the invoice is recent (less than 48 h)">
    In this case, updating the contact is usually enough. Follow the steps above.
  </Accordion>

  <Accordion title="After updating the contact, the invoice still shows the old data">
    Try step 4: inside **Invoicing**, click **Modify** on the line, remove the linked contact, and search for it again. On save the data updates. If it still doesn't, [contact support](#when-to-contact-support) with the booking reference.
  </Accordion>

  <Accordion title="The system errors out when saving">
    Screenshot the error and [contact support](#when-to-contact-support). These cases are usually a configuration or VeriFactu lock that we review from the back.
  </Accordion>
</AccordionGroup>

## When to contact support

* The invoice is in **VeriFactu** and is **older than 48 h**.
* The system errors out when saving.
* After updating the contact, the data **doesn't reflect** on the invoice even after forcing the refresh.

<Warning>
  Don't manually edit the invoice PDF or try to "rewrite" the data through other paths. Any modification outside the proper flow breaks the coherence between what's invoiced and what's reported to the tax authority.
