Can I get invoices addressed to my holding company?

The TRN half is yours to set: Settings → Ordering, and it then prints on the platform's tax invoices to you — and turns your own customer invoices into Tax Invoices at the same time. The billed NAME is your restaurant's name on the account, so send us the exact legal name you need and we will change it. Both appear on a proper FZC tax document with a sequential number, 5% VAT and the bank details, which is what your accountant needs to file it as-is. If your registration is not ready, leaving the TRN blank is honest rather than broken: the document is titled Invoice and simply has no TRN line.
