B2B card payment volumes will grow from $5.9 trillion in 2026 to $10.9 trillion in 2030, according to new Juniper Research data. That is 85% growth in four years. Over the same period, the broader B2B payments market is forecast to grow by 17%.
In other words, card payment volumes will grow at nearly five times the pace, so it’s clear that this is a real change in how companies pay. But what the trend represents is more interesting than the numbers themselves.
The Control Layer
Corporate cards have effectively become management infrastructure. Spend limits by employee or category, merchant restrictions, geographic locks, real-time notifications, instant lock and unlock – these controls, available on modern cards, give finance teams a layer of governance that other payment methods simply cannot offer. A bank transfer moves money. A corporate card moves money and generates a more structured record of how, where, by whom, and for what.
In particular, virtual cards are accelerating this shift. Juniper Research notes that virtual cards have moved well beyond their original role as a security measure to become instruments of control and convenience. This also begins to show up in how companies actually deploy them: not just for travel and expenses, but for vendor payments, team-level budgets, and platform-specific spend. At Wallester, we see this gap play out in client conversations every day – between what the cards can do and how companies are actually using them.
“We still have to inform clients – especially the big spenders, especially big companies – that they can do more. You can use those cards for every single expense. Take all the expenses that you have in your company. All of them can be easily organised in the same interface,” says Mattia Piazzano, client relationship manager team lead.
“It’s an ongoing conversation – little by little. Every month when our managers are reaching out, you tell them: you can do this, you can add that, explore this feature,” Piazzano adds.
There is also an employee dimension that the Juniper data points to. It tends to get less attention. But issuing company cards to more junior employees, with sensible controls in place, has a measurable trust effect because it removes the approval cycle for routine purchases and signals confidence. For finance teams, it means fewer reimbursement requests. For employees, it removes a friction point that most manual expense policies quietly create.
Where It Can Go Wrong
At the same time, not every implementation goes smoothly. Juniper Research flags overly restrictive controls as a potential risk as well: a card programme that forces employees to seek approval for small purchases creates frustration without adding oversight. The goal should be visibility and structure, not restriction for its own sake.
Getting this balance right is crucial. The tools exist, so this is largely a policy question rather than a technical one. The harder part is defining sensible limits, communicating them clearly, and reviewing them as the business changes.
“One of the biggest parts of this job – especially for mid-level CRM managers – is to guide clients on how to use this solution at its best and to optimise whatever’s available,” says Piazzano. “We have a good relationship with clients, but we’re not really parenting them.”
And most do get there. At Wallester, the pattern we see most often is companies starting with a small number of virtual cards and expanding quickly once the visibility takes effect. When finance can see spending by team and by category in real time, the appetite to extend that visibility tends to grow fast.
The Juniper Research numbers reflect that dynamic at scale. Cards are winning in B2B payments because they are the only payment method that gives finance teams a structured, real-time view of how corporate money moves.
