If you ever need an addendum resent to a merchant, you can resend it yourself if need be. It does not HAVE to come from Finance.
Important to note that this is for a RESEND. Finance should still write up and send the original addendum. We just don’t need to rely on them to resend if we want to take care of it ourselves. A simple copy/paste from their original email (which always resides in ESP notes) is valid.
