What is the best billing method to use with a contractor?

[Bill Coleman]

Last night I had a meeting with a potential contractor for two simultaneous rehabs. We talked about the different ways that we can work and how he gets paid: cost plus, fixed price, etc

I would like to know how other pros are structuring their payments and what is the preferred method of billing. I am interested in finding out what method produces the best results for the least money.

only 400 trips after the big first one huh? I forget way more than that. Ha. Easily 3 times a day for the first week or so.
