To make sure that you get paid at the end, offer to certify the kitchen. Issue a cert with what was used, who did it and who has inspect it. Only issue the cert after the project was paid. Magic. My customers are pre-paying us.
I used to do the kitchen then wait for x to check it out, y to see it, w to approve it & 1 month later still not paid. So now i certify the kitchen (anyone can do it) & that issue is gone. The customers are very fast to pay
