hey guys, im working on putting a bid together for a chain of restaurants in my area. i am offering them a price with for 1yr contract along with a price for a 2yr contract. what i am afraid of is the fuel 2 years from now skyrocketing. i want to include a fuel surcharge into the 2 yr. contract price. my question is what is the best way to do that? do i do it monthly? say if fuel price were higher than avg. during a month, then do i add the fuel surcharge onto next months bill? how do you guys do it? *how i do my billing for them: i have added together my total service costs for lawncare and snowplowing+ice control and came up with a price, i take that price and divide by 12 months, so i will be getting a monthly check from them every month for the same amount.
