Sample note
"Hi Sarah, thank you for trusting us with your water heater. It was great meeting you and Max the dog. If anything feels off, call me directly. Mike, your technician." Short, specific and signed by a real person.
Cost and return
Cards, stamps and five minutes of office time cost very little compared to one referral or one repeat call. Track it for three months and the numbers usually justify it.
