- Customers want mobile-friendly ways to view and pay utility bills now. Their expectations can change faster than a multiyear IT roadmap.
- Delaying billing modernization can prolong costs across departments, including paper bills, avoidable calls, and payment delays.
- Billing and payment platforms can often be implemented alongside a customer information system (CIS) migration or advanced metering infrastructure (AMI) rollout, rather than waiting for those projects to finish.
Whenever I talk with utility IT and operations leaders, I tend to hear a version of the same plan: get the CIS migration or the AMI rollout done first, then circle back to billing and payments.
It sounds like a safe sequence. Nobody gets challenged in a board meeting for prioritizing back-of-house work before customer-facing improvements.
But after years of watching utilities make that call, I’ve learned that waiting is often the wrong answer. The full cost of delaying the customer experience is rarely considered. Once it is, postponing utility billing software modernization becomes much harder to justify.
What Are Utility Customers Asking For?
Utility customers want convenient, intuitive, mobile-friendly ways to view and pay their bills. Their expectations are changing faster than most multiyear technology roadmaps can accommodate.
Mobile preference for bill payments jumped from 29% to 45% in a single year, according to InvoiceCloud’s 2026 State of Online Payments Report. That’s a substantial shift while many CIS programs are still early in a three-year timeline.
J.D. Power’s utility digital experience score sits at 616 out of 1,000 which was dead last against wealth management, insurance, and retail banking. The study also found that nearly one-third of utility websites failed basic navigation standards. Utilities can use this digital accessibility readiness checklist to identify common barriers.
Every month utility billing software modernization waits, the gap between customer expectations and the available experience can grow.
What Does Delaying Billing Modernization Cost?
The cost of waiting extends beyond a technology project budget. It can include paper bills, avoidable service calls, delayed payments, and costly collections or shut-off processes. These expenses rarely appear together in an IT business case because they sit across different departments and budgets.
Consider three common sources of cost:
- Paper billing: At approximately $1.10 per mailed bill, a utility sending 30,000 bills each month would spend about $396,000 per year on printing and mailing.
- Contact center demand: Calls can cost $20 to $30 each. Some calls—for example, questions about forgotten passwords, missed reminders, or payment confirmation—may be avoidable.
- Payment delays: In InvoiceCloud research on payment delinquencies, 44% of customers who encountered a payment problem outside business hours waited until the next day to call. That delay can affect days sales outstanding and may contribute to costly collections or shut-off processes.
Because these costs are not tracked as one number, they are easy to underweight compared with a CIS or AMI program that has a clear, visible price tag.
Does Billing and Payments Modernization Need to Wait for a CIS Integration?
No — not always. Modern utility billing and payment platforms can often be implemented in parallel with CIS or AMI initiatives through modular architecture and pre-built integrations.
The question I hear most often from IT leaders is fair: Won’t adding a payments platform in the middle of a larger program strain a team that is already stretched thin?
Ten years ago, it might have. Today, the architecture has changed.
Modern utility billing software can sit alongside a CIS rather than being embedded within it. Standardized, pre-built integrations connect to providers utilities already use, including Oracle, SAP, Muni-Link, CentralSquare, and others.
When a CIS provider and payments vendor already have a joint deployment playbook, implementation can focus primarily on configuration rather than a custom integration built from scratch.
The internal effort can reflect that difference. Depending on the utility and project scope, a digital payments deployment may require only a few hours per week from a small internal team, primarily for configuration decisions and user acceptance testing. Such deployments can go live within a few months.
What Happens When Utilities Modernize Billing and Payments in Parallel?
Utilities that move forward with billing and payments during larger IT initiatives can increase digital payment adoption, grow AutoPay enrollment, reduce bill-related calls, and free staff for higher-value work.
San Jose Water and Sacramento Suburban Water District did not wait for their core systems work to finish. Both modernized billing and payments alongside other technology projects through joint implementations with their existing CIS providers.
San Jose Water reported:
- A 76% increase in digital payments
- A 44% increase in AutoPay enrollment within nine months
Sacramento Suburban Water District reported:
- A 149% increase in digital payments
- 32 staff hours saved per month, creating more time for long-delayed projects
Across InvoiceCloud’s enterprise utility deployments, customers report the following results:
- A 35% reduction in bill-related call volume
- A 40% increase in on-time payments
- A 49% average increase in digital payment adoption during the first year
These benefits can begin during the broader IT program — not only after a multiyear project is complete.
When Should a Utility Wait to Modernize Billing and Payments?
A utility may need to wait if it is approaching a CIS cutover and does not have the staff capacity to support another implementation. For utilities in the early or middle stages of a program, parallel modernization may be practical—especially when the CIS provider and payments vendor already have an integration playbook.
I’m not suggesting that every utility should modernize billing and payments alongside a larger IT initiative. If your organization is in the late stages of a CIS cutover with no bandwidth to spare, that’s a real constraint.
But many utilities are in a different position: early or midway through a program, working with a CIS provider that already has a payment integration playbook, while leadership asks what the multiyear investment has produced so far.
If that sounds familiar, the question is not whether utility billing modernization is worthwhile. The better question is:
Are you measuring the total cost of waiting against the total cost — and potential value — of moving now?
