I'll start off by saying this is my first year owning a lawn care business, but worked for one previous to this. At the beginning of the season gas prices were a little over 2.00, and now they are at 3.09 here. I didn't have any of my customers sign contracts this year, but want set up a contract for them to sign next year. Anyways should I have them sign the contract this year or wait until spring? I need to raise prices due to gas, how much should I increase as of now? 15%? Also if I send out a contract this fall should I also hit them with a letter increasing prices?
