Does anyone charge their customers for the costs you incur, to charge them money? A box of envelopes is $65. A book of stamps is like $8. Then there is the time spent entering data into quickbooks, printing everything, and then stuffing into envelopes and driving to the post office to mail them. I am thinking about adding a small fee (like $1.50 or so?) to each invoice next season. I will obviously have to include in my spring letter that the additional charge will appear so it won't catch them off guard, but I am guessing it still won't go over real good. Or do you just look at it as part of your overhead you need to think about when you bid a lawn?
