Revenue Assurance: The customer who calls about a wrong charge is twice as likely to leave. The one who doesn’t call already has.
Here’s a number the churn models don’t see.
In early 2024, Nanos Research surveyed 1,301 Canadians with a telecom subscription for the CRTC. A little under a third, 31.5 percent, said they’d had a complaint about a service in the past 12 months. Among the mobile complaints, 45.6 percent were about billing disputes or errors, and that’s with the price of the plan itself excluded from the count.
Now the part that matters. Almost everyone with a complaint called their provider, 99.1 percent. And 42.6 percent of them said the provider did not resolve it to their satisfaction.
What did those people do next? Mostly nothing. Eight in ten had never heard of the CCTS, the complaints body. Only a tiny number said they switched providers on the spot. They just hung up, paid the bill, and carried on.
For a while.
Why the numbers everyone quotes are the small ones
The CCTS took a record 23,647 complaints in the year to July 2025, and billing was the biggest category. I’ve written about that report before and I’m not going to walk through it again. The point here is different. The Nanos work says the CCTS sees a sliver of what actually happens. Most billing errors never become a formal complaint. They become a phone call that ends badly, and then a feeling, and then a decision that gets made months later when the contract comes up.
That decision shows up in your exit survey as “price.” It never says “the credit you promised in March didn’t appear until May.”
I don’t have Canadian data that follows the customer from the wrong bill to the port-out request. Nobody publishes that. The closest I’ve found is American, and it’s recent. Recon Analytics published an analysis on February 10, 2026 of 1.47 million US consumer and business survey responses collected from the third quarter of 2022 through the end of 2025. Customers with billing issues were 2.5 times more likely to want to leave. Among home internet customers, 35.8 percent of those who had called about a billing question planned to leave their provider, against 18.8 percent of those who hadn’t called. The firm put the cost of billing-related churn at more than a billion dollars a year for each of the three national US carriers.
Different market, same plumbing. The customer who calls about the bill is the one you can still save. The one who got a wrong bill and didn’t call is already gone, and you won’t know until the 90-day notice goes out.
Why mid-market carriers feel it first
The big three can absorb a bad billing quarter. Rogers reported postpaid churn of 1.03 percent for the third quarter of 2026, up from 0.99 percent, and the market shrugged.
Mid-market and regional carriers can’t shrug. The CRTC’s 2026 market report says new and regional competitors took more than 55 percent of the mobile subscribers added in 2024. That’s where the growth is, and growth is a billing stress test. Every new plan, every bundle, every customer migrated from an acquired brand is a chance for the bill to disagree with the contract. The customers you just won on price are the ones reading the first three bills line by line, and they’re the ones with the least patience for a wrong one.
And since June 12, 2026, when Telecom Regulatory Policy 2026-43 took effect, there’s no activation fee, no plan change fee and no early cancellation fee on a contract without a subsidized device. The cost of leaving over a bad bill is now roughly zero.
Why the error is quiet
Three reasons, from what I’ve seen inside carriers on two continents.
The error is small. Not $400. More like $8 a month in a tax line that moved because the billing address and the area code disagree, or a proration that ran one day long, or a promo credit that expired a cycle early. The customer can’t tell if it’s a mistake or the plan. They pay it. They remember it.
The fix is a credit, and the carrier books a credit as a resolution. The customer books it as a second month of being wrong.
The billing system says everything’s fine. It rendered the bill it was told to render. The error lives in the gap between what the contract says and what the rating engine was fed, and nobody owns that gap. A former vice president at one of Canada’s largest carriers told me the statement errors he dealt with almost always came from billing data drifting away from the contract terms over time, not from the system breaking. That’s not a bug you can file. It’s a data check nobody runs.
So the error doesn’t trip an alarm, the complaint doesn’t reach a regulator, and the churn doesn’t carry a reason code. Quiet all the way down.
What I’d measure instead
If I ran retention at a mid-market telco this winter, I’d stop treating billing accuracy as a finance metric and start treating it as the leading churn indicator it is. Four moves.
Check every line of every bill against the contract before the statement exists. One hundred percent, not a sample. Sampling finds the error after a few thousand customers already got it. Banco Carrefour runs this on about 5 million personalized communications a month and reports zero errors in customer communications. That’s hiperValidation, and it’s the thing that turns a credit into a non-event.
Track wrong-bill incidence per customer as a churn signal. One wrong bill in the first 90 days should put a customer on the save list before they call, not after.
Move the credit forward. If validation catches it, fix it on the bill it would have appeared on, with one plain line that says what was wrong. A credit the customer never had to ask for is the only version of a billing error that builds trust.
Count the silence. For every billing call you log, there are customers with the same error who didn’t call. If 42.6 percent of callers leave unsatisfied, assume the non-callers are at least as unhappy and model churn that way.
None of this needs a new billing system. It needs a layer between billing and the customer that checks the number before anyone sees it. That’s the whole product.
