We are looking to finalize a commercial contract here by the end of the week. My question for all of you out there with commercial contracts is; when do you receive your money? Do your contracts pay for the month up front? Do you bill them at the end of the month? And if they are going to need things like pine straw or mulch changed throughout the year, do you include those prices and break that up into the monthly figures? or do you add that on when it is changed out?
