Just curious as to how everyone invites customers back in the spring? This is how I do it: In March I send out letters to everyone inviting them back. If I increase their rates or change their service, whatever, I do it in the letter. Mostly everyone stays the same, and mostly everyone gets the same form letter. The letter includes a postcard, stamped, with their name on it. If they want to return, they send the card through the mail. Or they can email or call. Pretty simple, eh? The problem this year was I had to drop a bunch of customers and I didn't send the letters to them. Unfortunately, many of the dropped customers waited until the last minute to call ME to find out if I was doing their lawns, and some were mad because I didn't let them know ahead of time. Other customers who got the letters never sent in their cards and found out when they called at the last minute I was booked up. One guy even waited until the end of May to call and find out why I hadn't been by yet. Oops.
