Change Payment Terms of an Open Invoice

Good Day:

  I am a newbie at this, so I apologize if the question is not very clear...  We are currently using GP2013.  At the time we create invoices in AP we do not know if the vendor will be able to accept credit card as a payment term.  We also automatically create invoices from a monitored email mailbox.  We would like to change the terms that an invoice will be paid from the default of the vendor to Credit Card or something else before the invoice is paid.  Is ti possible to do this?
