I want to get some opinions on changing the due date on my invoices. I currently bill on the 1st for the work done the previous month. Payment is due on the 15th, they get a late fee on the 20th, and service is stopped until payment is received after the 30th. I think I give them way too long to pay as it is now, and some still cant get it paid on time. I was thinking about mailing the invoices out a few days earlier, maybe the 25th, and make the due date the 10th. I will stop service if payment is not received by the 10th. I think the tall grass will get the payment in faster than the threat of a late fee. The only problem I see is that the first month I change to the new system they will get a bill on the 1st and the 25th of the same month. Has anyone done anything similar before? Had any problems? Did they get mad or did they understand?
