I have a customer who is just refusing to pay and after our phone call to him again he said to stop harassing him. we have tried numerous times to collect. his project is finished and he has a signed contract stating when the trade is complete customer has to pay for that trade. ie: customer is getting roof and gutters done, roof will be done on 10/5/2022 and gutters 10/8/2022 so on 10/5/2022 the roof should be paid in full and on 10/8/2022 the gutters then should be paid in full. we have file an intent to lien. set invoices called and tried to collect.
