Why these two fields matter
Your legal entity name and your TRN (Tax Registration Number) are the official details that must appear on the documents you send. Your legal name is the registered company name that belongs on invoices and agreements. Your TRN is what makes an invoice a valid UAE tax invoice. Setting both once here means every document you raise from then on prints them automatically.
Important
These are different from your Display name. Your display name is the friendly name clients see across the portal and emails. Your legal entity name is the registered name that appears on formal paperwork. They can be the same, but they do not have to be.
Enter your legal name and TRN

- Log in to your workspace.
- In the left menu, under Admin, click Brand.
- Open the Identity card at the top of the page.
- In Legal entity name, type your registered company name exactly as it appears on your trade licence. The hint reads "The registered name on your invoices and agreements."
- In TRN, type your Tax Registration Number. The hint reads "Your Tax Registration Number, printed on tax invoices." The box expects the long numeric TRN, shown as
100xxxxxxxxxxxx. - Click Save changes. A green Saved confirmation appears.
Check it on a real document

Use the Live preview panel on the right of the page. Switch to the Invoice or Quotation tab to see your legal name and TRN in place on the document. You can click Open the real PDF to build a genuine sample invoice and confirm the details render correctly.
Note
Leave the TRN blank only if your firm is not VAT registered. If you enter it, make sure it is correct, because it prints on every tax invoice you send and your clients rely on it for their own records.
The Identity card also holds
While you are on this card you will also see:
- Display name for what clients see everywhere.
- Tagline for an optional short line on your portal and emails.
All four fields save together when you click Save changes.
