Cancel a Year End Locked Sales Invoice

Accounting
1

Hi

I raised an invoice last June and closed down the accounting dyear at the end of that month.
Subsequently I realise that the invoice should not have been raised at all.

Naturally it is unpaid, but is not a bad debt, just a mistake.

What is the best thing to do please?

You can create a credit note for it under more options> credit note

Many thanks. The lock didn’t affect that at all.
