In case of customer rejected invoices with promotion at month end, what will be the procedure for the cancellation and reissuance of the invoice in next month with expired promotion?

In case the invoice is rejected by the Buyer due to some reason other than goods already supplied, and after a promotion month ended. Harrisons might need to issue a non-product Credit Note to cancel the “Rejected” invoice, then re-issue it with a non-product invoice with the correct price. This is because once the promotion period ends, the promotion code may not be valid to issue a new product Invoice.
