Materials in 10 days Labor in 30. Add a 1.5 percent service charge for anything over 30 days late. On a job with a big bill of materials I will get a down payment, or give the list to the customer and let them order the supplies. Doing it this way I make sure they understand 2 things: 1 materials must be exactly whats on the list, make, model, and serial number. 2 I will charge 15% of the total material bill for compiling and suppling the shopping list. Most of the people I have worked with are good about letting their contractors get a draw( progress payment) if I do this I usually get 1/3 of the labor on each draw, with the last one coming only after 100% completion and customer satisfaction, this is because too many fly by night contractors have been here and ripped people off so they are more cautious, and who can blame them.
