We are doing a slew of detach and resets for a roofing company. They are set up to pay 40% of the job cost once we have detached the system and the remaining 60% upon re-installation. We are having payment issues with the remaining 60% balance on some jobs. Is there a generic/general contract that we are able to send them? I do not necessarily want to send a preliminary notice or alert the customer of the roofing company regarding any payment issues- this would be a document that would be signed by the contractor only, for now. Does Levelset have anything along those lines?
