The Cost of Standing Still: Why Payments Can’t Wait for Your Next Big IT Project
Utilities running CIS migrations, AMI rollouts, or customer portal projects often defer digital billing and payments modernization until those larger IT programs finish. That sequencing can cost three to five years of stalled customer experience, while mobile payment preference has jumped 16 points in a single year. Utilities that modernized digital billing and payments in parallel with a bigger IT program report a 35% reduction in bill-related call volume and a 40% increase in on-time payments within the first year, without disrupting their core system work.
Where Customers Actually Are
InvoiceCloud’s 2026 State of Online Payments report, a nationally representative survey of 2,000 U.S. adults conducted in October 2025, found that 68% of consumers used a mobile device to pay a bill in the past year, making mobile the top payment channel for the fourth year running. Forty-five percent of consumers now name mobile as their preferred channel for paying bills, up from 29% a year earlier — a 16-point jump in a single year. Twenty percent of respondents still mail in check payments, but only 4% actually prefer that method.
Fifty-nine percent of respondents reported paying their utility bills online in the past year, behind phone service bills (70%) and internet service bills (68%). According to J.D. Power’s 2025 U.S. Utility Digital Experience Study, overall customer satisfaction with the utility digital experience scored 611 on a 1,000-point scale, climbing only modestly to 616 in the 2026 update. Utilities rank last among major service industries tracked by J.D. Power, well behind wealth management apps and websites (738), retirement plan providers (703), property and casualty insurance (698), retail banking (655), and commercial health insurance apps (653).
The same J.D. Power research found that 32% of utility websites and apps fail to meet basic standards for navigation and design, and 28% of utilities do not offer a mobile app at all — missing the channel their customers most prefer.
What Outdated Payments Costs
Among customers who already pay digitally, the top complaints are lack of payment reminders (22%), forgotten usernames and passwords (21%), and payments that take too long to process (18%). For customers who avoid digital payments altogether, the biggest deterrent is perceived online payment fees (39%), followed by limited or inconvenient payment options (18%), security concerns (14%), and a preference to talk to a person (13%).
Mailing a paper bill runs about $1.10 per envelope once printing, materials, postage, and labor are accounted for. A utility processing 30,000 bills a month spends close to $400,000 a year on paper bill production. Contact center calls for municipal utilities, on a fully loaded basis including labor, benefits, supervision, and overhead, can run as high as $20 to $30 each. When payment problems arise outside of business hours, 44% of customers simply wait to call the next business day, contributing to delinquency drag and days sales outstanding.
Where Digital Billing and Payment Platforms Actually Differ
Four areas separate platforms that move the numbers from platforms that simply check the boxes: AutoPay setup and self-management that lets a first-time customer enroll in minutes without calling customer service; payment method breadth beyond ACH and cards, including digital wallets like Apple Pay, Google Pay, PayPal, and Venmo, which have reached 44% adoption among higher-income households; pre-draft reminders and post-payment confirmations that reduce AutoPay cancellations and surprise-driven contact center calls; and marketing and adoption support from the vendor, since most utilities lack the internal marketing capacity to drive digital adoption on their own.
What “Waiting” Actually Costs
Large IT programs typically run 12 to 18 months to implement and another 18 to 36 months before results materialize, assuming everything stays on schedule. A Harvard Business Review study of nearly 1,500 IT projects (Flyvbjerg and Budzier) found the average project overran its budget by 27%, and one in six became a “black swan” with cost overruns of 200% and schedule overruns of almost 70%. That puts the realistic window before a utility could start billing and payments modernization on a sequential plan at three to five years, during which customer expectations keep moving, operational costs keep accumulating, and stakeholder trust in the broader IT investment gets harder to maintain. According to McKinsey (Smaje and Zemmel, 2024), large companies capture only 31% of the expected revenue lift from digital transformations.
Why Parallel Modernization Actually Works
Modern digital billing and payment platforms are modular, sitting alongside core systems rather than embedded inside them, and connect through standardized, pre-built integrations that established vendors already maintain with major CIS providers. Payment platform deployments now routinely complete in under six months. The internal IT lift is measured in hours per week from a small internal team for configuration and user acceptance testing — a different staffing profile than a CIS migration, which typically requires a dedicated core project team of five to ten people full-time for 12 to 24 months, or an AMI deployment, which can require cross-functional engagement for three to five years. Evaluating digital billing and payments early, even if implementation happens later, prevents the compounding integration complexity that comes from CIS, portal, and payments platforms designed in isolation.
What the Numbers Look Like With InvoiceCloud
Utilities that moved to InvoiceCloud during their broader transformation programs report a 35% reduction in bill-related call volume and a 40% increase in on-time payments across enterprise utility deployments. These outcomes typically show up within the first year of deployment, while the larger transformation program is still underway.
Two InvoiceCloud Customers, Two Stories
San Jose Water, a regulated water utility serving approximately one million people, modernized its billing and payment experience through a joint deployment with its Oracle Utilities CIS. Within nine months it reached 76% digital payment adoption, 56% paperless adoption, a 44% increase in AutoPay enrollments, and a 35% reduction in late payments.
Sacramento Suburban Water District, a publicly owned water utility serving nearly 195,000 customers, replaced a legacy payment system that was driving up call volume and absorbing staff hours through manual processing. In year one it saw a 149% increase in electronic payment adoption, a 41% increase in paperless enrollment, 32 staff hours saved monthly, and $13,500 saved in print and mail expenses.
How to Tell If Your Situation Fits
Readiness questions for leadership teams weighing parallel EBPP modernization include: Where are you in your major IT transformation timeline? What is your current digital payment adoption rate? How much manual work is your billing team absorbing? Does your CIS provider have an existing partnership with billing and payments vendors? Are CIS and portal decisions already locked in? Is leadership looking for visible value during the IT program? Utilities with the clearest case for moving now typically have low digital adoption, heavy manual processing, an existing CIS partnership with billing and payments vendors, and stakeholder pressure to show results before the larger program completes.
Frequently Asked Questions
Does digital billing and payments modernization need to wait until a CIS migration or AMI rollout is finished?
No. Modern digital billing and payment platforms are modular and connect to core systems through standardized, pre-built integrations rather than requiring deep changes to the CIS being modernized. Deployments now routinely complete in under six months, running on a parallel track to a larger IT program rather than in sequence after it.
What does deferring digital billing and payments modernization actually cost?
Costs include paper bill production at roughly $1.10 per envelope (close to $400,000 a year for a utility processing 30,000 bills a month), contact center calls that can run $20 to $30 each on a fully loaded basis, and delinquency drag from after-hours payment failures, since 44% of customers with payment problems outside business hours simply wait to call the next day.
How long does a large utility IT program typically take, and what does that mean for sequential modernization?
Large IT programs typically take 12 to 18 months to implement and another 18 to 36 months before results materialize, assuming they stay on schedule. A Harvard Business Review study of nearly 1,500 IT projects found the average project overran its budget by 27%, meaning a utility on a sequential plan can go three to five years before starting billing and payments modernization at all.
How much internal IT resource does parallel payments modernization actually require?
Payment platform deployment typically absorbs a small internal team’s hours per week for configuration decisions and user acceptance testing, with the vendor handling the bulk of integration work — a much lighter staffing profile than a CIS migration (five to ten people full-time for 12 to 24 months) or an AMI deployment (cross-functional engagement for three to five years).
What results have utilities seen from modernizing billing and payments during a larger IT program?
Enterprise utility deployments on InvoiceCloud report a 35% reduction in bill-related call volume and a 40% increase in on-time payments. San Jose Water reached 76% digital payment adoption within nine months of a joint deployment with its Oracle Utilities CIS, and Sacramento Suburban Water District saw a 149% increase in electronic payment adoption in year one.
