"I have been using Core since 2012. The program comes with a very easy to read and follow manual. Any type of questions can be answered by the amazing support staff.
I work for a water district. The program allows me to provide clients with email and also postal bills. I can send detailed reports on water usage, billing history and payment history to clients. I am able to provide messages to clients on their bills. The program has the ability to note clients as auto pay. The program has the ability to find clients by acct. number, meter number, APN number, and address or by last name. I highly recommend this program."
