My proposal/estimate and my service agreement are the same thing, all on one sheet together. If they dont like it then they will move on but there is no reason for someone to not want to sign it unless they are trying to pull a fast one and plan and not paying. A contract/service agreement is what separates the big boys from the "me and my mower" low ballers. No true Lawncare company out there with do weekly/monthly services without a signature.
