Customer and I went under contract to do a kitchen and master bath remodel. I believe the job was completed to a professional status and the customer is seemingly nit picking to the point i cannot meet up to his expectations. He owes me the final 25% of the invoice and is refusing to pay, he is saying he will hire a contractor to come and finish the job and deduct it from my remaining balance. $21,000 is left to be paid. But I’m not sure if not pulling a permit is going to cause me to lose the case if we go to court.
