Built for Utility Billing Software
Utility payment processing built
for the billing cycle
CSIPay is the embedded payments platform for utility billing software in the Constellation ecosystem. Online bill pay, autopay, and counter payments all post back to the customer account.
Every account bills every cycle, and most pay in the last three days.
Utility billing is high volume and unforgiving. Every active account generates a bill every cycle, payment behavior clusters hard around the due date, and a customer facing disconnection needs a payment to post now, not tomorrow. Online bill pay software has to absorb that due date surge while giving customers a way to pay that does not involve an envelope.
Autopay changes the economics: an enrolled account pays on time every cycle without touching staff. But enrollment, stored payment details, and cycle scheduling all depend on the billing system's data, which is why bolting payments on from outside creates reconciliation work every single cycle. CSIPay embeds the payment layer in your billing software, so payments post to accounts the moment they happen.
Everything billing software needs to run the cycle.
Online bill pay
Customers view and pay their bill online, and the payment posts to the account in your system.
Autopay enrollment
Enrolled accounts pay automatically on the due date from a stored card or bank account.
ACH and bank payments
Offer bank payment alongside cards, a natural fit for recurring utility bills.
Counter and phone payments
Office staff take walk in and phone payments through the same embedded layer.
Security built in
Stored payment details and every transaction are protected to PCI DSS Level 1.
Revenue for your platform
Utility payment volume becomes platform revenue through our partnership and PayFac as a Service models.
Infrastructure grade payments for infrastructure software.
CSIPay is the embedded payments platform for Constellation Software and Jonas Group companies, including software serving utilities and municipal billing. Utilities do not switch systems often, so the payments partner has to be built for the long term, and the relationship stays inside the ecosystem rather than with a revolving door of outside processors.
The due date surge is the design constraint, and CSIPay is built for it: more than 4,000 merchants processing behind a 99.9% uptime SLA and PCI DSS Level 1 security, across the US and Canada, including card not present payments in Canada, which is what nearly every online bill payment is.

Utility payment questions.
How does autopay work in utility billing software?
A customer enrolls once, their card or bank account is stored securely, and each cycle's bill is paid automatically on the due date. Every autopay posts to the customer account in your system, so enrolled accounts simply stop appearing on the past due list.
Can customers pay a utility bill online without enrolling in autopay?
Yes. One time online bill pay lets a customer pay the current balance by card or bank payment whenever they choose, and the payment posts to their account immediately.
What payment methods can a utility offer?
Cards and ACH bank payments, online, by autopay, at the counter, or by phone, all running through the same embedded layer and reconciling to the same accounts.
Can the system handle due date payment surges?
Yes. CSIPay runs on infrastructure backed by a 99.9% uptime SLA, built for billing calendars where a large share of payments arrive in the final days before the due date.
