I was talking to a lawn service who has been in business for 20+ years. He told me that he talks to his customers personally when he feels they are due for a price increase. Here is the thing that stuck me. He asks them what they feel is a fair dollar amount. He told me that he feels they will not feel as upset about it if they have a part in the raise. He just had one of his best customers raise him up $15.00 a week. It seems that if you could get responses like that or an average of say 5-10 a week more that it would save some of the customer loss that you typically get when raising rates. It also seems like it would let you know which customers are good, by their willingness to pay you a fair amount. I do think that it might come across as unprofessional though. What do you guys think?
