how many of you offer financing? usually the customer has to sign a completion certificate after the job is done and thats when you get paid..my question is this,is it common for a customer to not sign in order to avoid getting billed? acting like they are unhappy with a GOOD JOB just to get out of paying> ? how is the contractor(me) protected against this? i know there is court but my guys and materials need to be paid for;is it safer when financing?
