Boy do we got one now! A commercial account has a 45 day turn-around on invoices. They sign to a Net15 term of payment and were 60 days late in the first payment. We just recieved it. They want to re-negotiate their contract terms to 13 cuts instead of 26. Here's the issue. We bill for 8 mos. to ease the payments on clients and increase our income time. Never have had an issue til now. I really don't need the loss of 1/2 a large contract, but I don't want to be a PITA myself. Any suggestions?
