The job has been completed. Trying to get paid the guy writes a check it was incorrect. I asked for a correctly written check says we have to go and fix a punch list and we can get paid. Contact him after completing the punch list to get paid then ask for business license and insurance which we provided.Next day contact about getting paid then says Needs workers comp exemption which he should have asked for all of this at start of job. Now is pretty much withholding our payment has been for going on 3 weeks. Now wants to hold .37% of our money because we don't have workers comp exemption. But we don't have any employees.
