Can you guys tell me the best way or ways to do what I am trying to here..... I use quickbooks and enter charges for mowing under each customers register. I then create a statement and send that at the end of the month. This works great and I love it. Well, How can I bill for a mowing/plowing agreement (or any service agreement) with 12 equal monthly payments. For instance customer Jane $45 mow, 26 visits a year is $1170 a year and I want to bill out $97.50 each month.
