Payment Options

We know convenience is important to our customers, so SD1, in partnership with Paymentus, offers a variety of ways for customers to pay their bill. 

Please note that some payment options will include a pass-through convenience fee that is charged by and goes directly to Paymentus, SD1's third-party vendor. Learn which options include a convenience fee in the payment options chart.
