[Question] forgot to invoice client a few months ago - how to rectify

[SilverNodashi]

Hi,

I have a new company which I want to register VAT on and noticed that we didn't invoice a client in May for services rendered to the value of R9300. His payment reflects on the 24th and 29th May. Other clients were invoiced after that date though. The current last invoice number is 0014.

How do I rectify this without problems?

Do I simply just issue an invoice, following the invoice sequence thus 0015, but stipulating the date as the 24th May?

That's what we'd do, unless I had already filed the VAT return for the month concerned.
(Which I gather isn't an issue in this case).

The other option (if you're trying to protect a numerical sequence in strict date order) is to issue the backdated invoice as invoice 0004A (as example).

Yes I would do the same inv no with an "A" as well

I still need to register for VAT and thus wanted to find out if it would be a problem.
My OCD doesn't play well with this though, but the first option sounds a bit better than adding the "A" at the end

I guess it would be fine, just this one time?
