I have several mistakes when submitting my invoices. every time I call in in hope by letting someone know that they would send to necessary department. this is the third time this has happen. After going through my invoices never mind.

all I'm trying to find out can you correct a invoice after you have submitted it? 

I need to edit an invoice that is archived, but not submitted.
