I am a landscaper....I some how backed into doing a few fertilization accounts. Mainly for neighbors, and past customers. I am not advertising for this, I am just doing it for people who ask to have it done...mainly to pay for my licenseing and my equipment. I put down a lot of roundup on the landscaping side of things. Anyway, I was curious how do you schedule your appts with your customers. Do you send them a letter at the beginning of the year telling them what dates your will be there, do you call them before each visit. I am clueless....please help! I want to make this as easy as possible, but since these are neighbors and past customers I want them to be there when I do it, in case they have any questions. My thought is that I need to send them a letter before each app telling them when I am going to be there. Is this common? Any suggestions?
