Fireball: <br>You mentioned that your minimum is $50 per month. That seems incredibly low. What exactly are you doing for $50? I expect to get at least $30-$35 PER WEEK on our accounts. <p>I agree that it is good to reward a customer that gives you a referral. I have never quantified it, but I figure if you add labor, follow up time, marketing, advertising exp, etc then each new account probably (costs) $100 plus to get. That referral therefore has saved you most of those expenses. I have even gone so far as to give a free month of service for someone that refers me a neighbor. I can make that up in a month or so by the increased productivity and decreased windsheild time. (We have annual agreements and <10% attrition so I don't worry about the referral fee since I know this person is more than likely be a long term customer.)<p>Has anybody figured a way to actually calculate what each new account costs? It has to be significantly more than the $15-20 range that has been discussed.
