- Customers expect fast, mobile bill payment now, and delays in modernization widen the gap in satisfaction and digital experience.
- Waiting hides real costs in paper billing, call centers, and delinquency, making delay more expensive than it first appears.
- Modern billing and payments can run in parallel with CIS work through modular integrations, delivering benefits within months.
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’s the safe-sounding choice. Nobody gets challenged in a board meeting for sequencing the “back-of-house” work before the customer-facing stuff.
Here’s what I’ve learned after years of watching utilities make that call: it usually the wrong answer because nobody considered the entire cost of waiting to modernize this critical customer experience. Once you do, “wait” gets a lot harder to justify.
What Utility Customers Are Actually Asking For
Customer payment expectations won’t be patient while utility roadmaps get sequenced. 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 not a slow drift; that’s a step change happening while most CIS programs are still in year one of 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. Nearly a third of utility websites fail basic navigation standards, causing significant customer frustration and driving low satisfaction scores.
Every month utility billing software modernization waits, that gap compounds.
What Waiting Actually Costs
This is the part that rarely makes it into an IT business case, because it’s spread across three or four different budgets instead of sitting on one line.
Paper bills run about $1.10 per envelope. A utility processing 30,000 bills a month is looking at close to $400,000 a year just to keep printing them. Contact center calls can cost $20 to $30 each and a large share of them are avoidable with inquiries about forgotten passwords, missed reminders, and “did my payment go through” questions. Then there’s delinquency drag: 44% of customers who hit a payment problem outside business hours simply wait until the next day to call, which is a measurable hit to days sales outstanding and can even trigger costly shut-off sequences.
None of that shows up as a single number anyone tracks. That’s exactly why it’s easy to underweight against a CIS or AMI program with a clean, visible price tag.
Does Billing and Payments Need to Wait for Your CIS Integration? No — Here’s Why
The question I hear most from IT leaders (and it’s a fair one) is: won’t adding a payments platform mid-program strain a team that’s already stretched thin on the CIS work?
Ten years ago, yes. Today, the architecture has changed.
Modern utility billing software is modular, meaning it sits alongside your CIS rather than embedded inside it, connecting through standardized, pre-built integration with the providers utilities already run, including Oracle, SAP, Muni-Link, CentralSquare, and others. If your CIS provider already has a joint deployment playbook with a payments vendor, the work is mostly configuration, not custom integration from scratch.
The internal lift reflects that. A digital payments deployment only takes a few hours a week from a small internal team for mostly configuration decisions and user acceptance testing. These deployments now routinely go live in a few months.
What the Numbers Look Like When Utilities Move in Parallel
San Jose Water and Sacramento Suburban Water District didn’t wait for their core systems work to finish. Both ran billing and payments modernization alongside these projects, through joint implementations with their existing CIS.
San Jose Water saw a 76% lift in digital payments and a 44% increase in AutoPay enrollment within nine months. Sacramento Suburban saw a 149% increase in digital payments and freed up 32 staff hours a month for projects that had been sitting on a wish list for years.
Across enterprise utility deployments generally, InvoiceCloud customers report a 35% reduction in bill-related call volume, a 40% increase in on-time payments, and a 49% average increase in digital payment adoption during year one, not at the end of a multi-year program.
The Question Worth Asking
I’m not going to tell you every utility should modernize billing and payments in parallel with a bigger IT program. Some genuinely shouldn’t, especially if you’re late-stage on a CIS cutover with no bandwidth to spare, that’s a real constraint. But most utilities land somewhere else: early or mid-program, with a CIS provider that already has a payments integration playbook, and a board asking what the multi-year investment has actually produced so far.
If that’s closer to where you sit, the question isn’t whether utility billing modernization is worth doing. It’s whether the total cost of waiting is actually being measured against the total cost of moving and not just ignoring that evaluation because “we’re too busy with other projects.”
