It sends bills, keeps track of your account and controls connections. Users not current on their bill are not permitted to connect. For those paying cash or check, Regulus will e-mail you an invoice two weeks before the due date. Those paying by automatic credit card debit do not customarily get an invoice, but we can also email one upon request.
All customers get a reminder on the due date.
If you are paid up, it will tell you so. If not, it will tell you that you have two weeks to make a payment or be disconnected. Finally, two weeks after the due date, Regulus cuts off unpaid accounts. It happens automatically at the stroke of midnight. Regulus is a reliable program, but humans do make mistakes.
