I dont know whether I understand what you mean when you say "another
invoice... which is the reverse.."

AFIK In Accounting, you do not reverse a "deleted" invoice, and neither
do you delete an invoice to reverse it, you issue a debit/credit note to
"double-enter" the invoice thereby "neutralizing it".

... or maybe I just did not understand what you meant.
