I'm interested in seeing what detail everyone goes into on their full maintenance 12-month equal payment plan invoices. Do you simply put "full maint. for the month of may and a price or do you list out each and every service your preformed during that month and the date you did them on. Keep in mind you have a contract for these customers with the services understood that you are to do throughout the year, do do you still put the services on every invoice with a date? For those that just put "full service" and a price on their invoices how to you keep track of what you did on that property if you ever have to go back and look? Do you file it elsewhere and just don't put it on the invoice?
