I have a customer (the GC) requesting that i change the thru date on an unconditional release from 10.31.19 to 9.30.19. Does that really matter if what amount on the waiver is what they've been paid for thru 10.31.19. The customer has only been paid once. Their invoice was dated thru 9.30.19. They have not invoiced us October nor November, so technically I can have it say thru 11.30.19, right?
