CEDP's second year: Why ISOs could lose merchants over broken data
A financial controller at a building supply distributor called us this summer with what they thought was a simple question: why had the cost of taking commercial cards gone up three months running?
Her company had cleared Visa's Commercial Enhanced Data Program (CEDP) checks last fall and achieved verified status, meaning they qualified for discounted rates. Nothing about how it billed customers had changed.
We took a look, and about an hour later we found the reason. It was down to a change in the company's invoicing, which had moved within its ERP. This seemingly minor upgrade meant it was no longer sending line-item detail to the gateway for part of its volume. Nobody at the distributor or processor noticed, or if they did, they didn't bother to notify them.
This is just one of many example conversations I've had this year. Without sufficient knowledge of why fees have gone up, the easy scapegoats for merchants are ISOs who rightly made CEDP verification part of their pitch over the past 12 months. This problem makes it very real that ISOs could lose commercial card merchants to competitors marketing lower rates.
Visa reassesses verified status continuously under CEDP. It's foolish to think that a merchant that successfully achieved CEDP verified status will continue to do so on autopilot. A set-it-and-leave-it strategy is bound to go wrong. A small, innocuous change can disrupt transaction data submission.
Many missteps and confusion with CEDP come from the merchant and the processor looking at a transaction and drawing different conclusions or seeing different things in it. It helps to view CEDP from both perspectives because the agent is left in the middle to reconcile the issues.
The merchant's view
Enforcement began Oct. 17, 2025, and on April 17 of this year, Visa retired its Commercial and Small Business level 2 interchange programs, leaving level 3 as the only route to a lower rate on a Visa commercial card.
That leaves little room for error. A merchant that falls out of Verified status but still sends clean data waits for its discount to come back as a credit after Visa reviews each transaction. A merchant whose data fails doesn't get the discount back at all. It can end up paying more than if it had sent no enhanced data, once Visa's 0.05 percent program fee is counted. Visa also raised Product 3 rates on small business cards by 65 basis points in January, which narrowed the savings even for merchants doing everything right.
The hard part for merchants is that the data Visa checks starts in their own systems, far from anything they think of as payments. An ERP upgrade, a new billing platform or an acquisition can change what reaches the gateway. So can a sales team that starts keying in orders a different way. Tax amounts stop reconciling with line totals. A purchase order field fills with the same value on every transaction.
Think of it like an athlete who needs to comply with drug testing. They can take the same supplements for years and still fail a drug test because the manufacturer changed the formula. Nothing about the athlete's routine changed. But the drug testing agency takes a dim view and bans the athlete all the same.
Mastercard adds to the confusion. It kept its Level 2 and Level 3 programs, and its checks are far less strict than Visa's. So when a merchant or its rep asks whether the enhanced data is working, the Mastercard lines on the statement can say yes. The same data can be failing on Visa, where most commercial card volume runs, and nobody goes looking because something appears to be working.
The processor's view
I've publicly criticized some processors over CEDP for years for autofilling required fields with placeholder data, so there was certainly some shock when Visa's AI-powered fake data detection test started working.
But it's important to acknowledge the processor's position is harder than merchants realize. A processor sees the data that arrives with the transaction but it doesn't see the invoice. It can pass along whatever the merchant's systems produce, but it can't know whether the line items describe a real sale.
Visa reports validation results to acquirers and processors. Turning those results into a clear warning for one merchant is work that plenty of shops still haven't finished, and Visa's own communication about the program has been thin. Consequently, a merchant's qualification level can slowly decay as each participant in the payment ecosystem relies on someone else to monitor it.
Where this lands for the ISO
Look at it from the merchant's desk. Its effective rate on commercial cards is rising, and the processor's statement doesn't explain why. Then someone walks in who can. Some ISOs are already coaching their agents to do exactly that. The pitch skips the rate question and asks the B2B merchant how its commercial card transactions are actually qualifying.
It's a good question that the incumbent agent should be asking regularly. When someone like me finds the broken field instead, the merchant starts wondering what else its current provider has missed. That doubt is how accounts leave.
The pushback I hear from agents is fair to a point. Commercial card merchants are a small share of most portfolios, and the data lives in the merchant's systems, not the agent's. Both are true. They're also usually the largest tickets and the steadiest residuals in the book. And a CFO watching card costs climb doesn't much care whose system dropped the field.
By the time Visa's April 2027 rate changes arrive, I expect the agents still holding their best commercial accounts to be the ones who asked those merchants for transaction-level qualification data this fall. The rest will hear about the problem the way that controller's rep did, after the money was gone.
