I've been setting up all of my maintenance accounts to bill in advance, monthly. I told my husband this tonight and he looked at me like my head was spinning, saying that he would think people wouldn't be pleased with being billed in advance for maintenance. I've read the threads, and here's how I've set it up: Ave. a 32 week mowing season, spreading payments out over 8,9,10 months, depending on what the customer would like. I've started the first cuts of the season this week and will invoice on April 1. This invoice will cover April 1-30 (and the March clean up already figured into the monthly cost averaged over the chosen amount of months by the customer). Am I smoking crack here? Should I be invoicing in arrears for maintenance? I guess my thought was that if I bill in advance, if I don't have their payment by the 15th, I can suspend services and only be out 2 weeks versus an entire month of time. Tell me if I'm crazy. . .
