I think a couple of years ago I mentioned this and I thought I would bring it up again.... Obviously one of the issues in this business is getting your regular maintenance clients to pay on time. One of the practices we implemented for our regular monthly clients who payed a set amount each month was a Payment Booklet. We had them made by a local printer. They looked exactly like the payment booklets you receive for mortgage payments, student loan payments, vehicle payments, etc.... The payment sheet included our address, their name and address, the amount owed and the due date. When we sent them to the clients, we included a simple letter letting them know their payment was a set amount and it was due on a certain day...and for their convenience, we provided the payment booklet. We did not have to create and mail out invoices for these clients and they knew exactly what they owed and when it was due. And depending on how far you want to go, we also included in their payment package 12 pre-addressed and pre-stamped envelopes. The envelope had our address on it already and a 1st class stamp. All they had to do was write the check and pop it in the envelope and send it with their regular bills. We gave the clients the option to choose a payment date (1st, 10th, or 20th of the month) Had a definitive impact on our cash flow because we could rely on receiving payments on certain dates each month.
