BTW, these aren't just non-standard workflows. From an accounting perspective, they are wrong workflows because they break auditability. Technically, you aren't supposed to ever change a posted invoice. Ever....
OK. The only reason we repost invoices is to correct typos in the description of line items. What is the GAAP way to do that? Cancel the invoice and make a new one? If so, I'll ask our AP person to start doing it that way. Regards, David.
