I am trying to bill the GC for materials before they are on site. The agreement with our manufactures is that we have 30 days to pay for that material and we have a 25k line of credit. The issue I receive from the GC is that they do not want to pay for material until it is onsite or until it is installed. The product we sell is custom and we have a pretty quick turn around on installation. The GC will state that they are not a "bank" which I'm not either. :/ How do get on the same page with them and be reasonable, as once the materials arrive onsite then they pay 30-90 days later which is past my MFG's timeline. Just as an example I can not fund 10 plus projects each month on my own if the materials cost 10K each and each of them pay at their own rate at a different pace.
