Incorrect invoice number

[Ender]

I submitted an invoice to my current agency with number like 123456789. I pasted my company VAT number in the wrong field

The only way to change an invoice, submitted with this agency, is to produce a credit note and a new invoice. Should I do that?

Is it a big no-no with HMRC to have an invoice number out of order?

I would have thought it entirely an internal reference number for your benefit.

That's probably the best way to do it.
Have you rung them and asked them? Their accounts department will have a view.
