How do I deal with a proforma invoice which has been included on the VAT return but which the customer no longer requires?

Hello Mick1,

You could delete the transaction, This would then cause a Minus exception for the amount that has been previously filed to show you overpaid.

We would heavily advise to speak to your accountant as they may have a different way to action this and are able to give this kind of advise to someone like yourself. ]

Thank you.
