I am being asked to bid on a couple of properties. 1@ around 3000 per month and 2 @ 175 per month. Each property will be sreviced 42 times per year. I would like to start to charge a fuel surcharge so that if fuel goes up by 2-3% or more the surcharge would be added. If I bid a job and sign a contract and gas goes to $5 per gal. then I could loose profits. Is anyone presently doing this and is this accepted business practice?
