How to re-issue a finalized invoice with an amended company name or tax ID

A finalized invoice cannot be regenerated in place with new field values. It is an immutable tax document, so once it is finalized its details are locked. Updating the company name or tax identification number on the customer record changes only future invoices, which is why the existing finalized invoice does not pick up the edit. To get a corrected document, void the original and issue a replacement carrying the updated details.

Why the finalized invoice does not change

Once an invoice is finalized it can no longer be edited, and it does not pull in later changes to the customer record. Editing the customer's company name and tax ID updates the customer going forward, but the already-finalized invoice keeps the values it had at finalization. So the amendment alone will never alter the document you are looking at.

Voiding is the correct way to retire that document. A void is legally accepted and properly documented: it preserves the paper trail, keeps the invoice findable by its number, and treats it as zero value for reporting. The voided status is final.

How to issue the corrected invoice

After voiding the original, there are two self-service routes to the replacement.

Regenerate from the voided invoice. When you open a voided invoice in the UI, you can regenerate it. The original line items and fees are pre-filled and editable, and the regenerated invoice is linked back to the voided one for traceability. The service period cannot be changed on a regenerated invoice. Voided prepaid-credit invoices are the exception: those are regenerated by initiating a new wallet transaction rather than from the invoice.

Create a one-off invoice. Alternatively, issue a fresh one-off invoice with the corrected company name and tax ID. Confirm the customer record carries the updated values first, since the new invoice will take them from the record at issuance.

Either way, make sure the customer's company name and tax identification number are corrected on the record before issuing the replacement, so the new document reflects them.

One caveat on jurisdiction

In strict tax-compliance jurisdictions, the formally correct correction can be a credit note that references the original invoice plus a new invoice, rather than a plain void and reissue. If the end customer is in a jurisdiction where that distinction matters, confirm the required approach before voiding.
