Invoice error

[mr23ttbd]

I sent an invoice without realising it had the incorrect date on it. So I cancelled it, told the customer, and kept a copy of it for my records.
When sending the new updated invoice, do I keep the same invoice reference number, or give it a new one?
An example invoice A1 has an error, so its cancelled with the customer. Do you then send an updated invoice again using the ref number A1, or use a new one, A2?
And do I need to send a credit note to the customer, or just keep it for my book keeping? No money has been paid. Thank you.

I might be inclined to redate it and resubmit as you have already put them on notice of the error. Of course it might depend on what your accounts software permits.

You could if you wanted issue a credit note and a new invoice of course.

If you want to be pedantic then issue a credit note and reissue with a new invoice and number. If you want simplicity then just amend the original invoice with its original number. Sometimes your accounting system makes the latter more difficult. Do whichever is most convenient for you.
