Subscriptions in Payments Are a Pricing Hack, Not a Model
FX & Float: Operator Note
Over the last decade, fintech has heavily borrowed from the SaaS playbook: recurring revenue, monthly tiers and feature unlocks at higher plans. It has its upsides - it gives the company predictable income, clean ARR metrics, and investor-friendly multiples. But payments is not SaaS, and pricing it like SaaS has structural pitfalls.
Three reasons why subscription pricing in payments is less clever than it looks.
The first is cost structure. In SaaS, the marginal cost of serving one more customer is close to zero. The software is already there, and adding another user costs almost nothing. Subscription pricing fits because the cost structure is flat. If you are making a product like Salesforce, your costs change very little whether a user logs in for 5 hours or 150 hours per month. In payments, on the other hand, every transaction has a variable cost associated with it. Subscription revenue is fixed, but costs are not. This imbalance can work in some cases, but not where margins are already thin.
The second is the portfolio cross-subsidy. A customer sending $10,000 a month on a $99 subscription and a customer sending $100,000 a month on the same plan are not the same. One pays an effective rate of 0.99%, while the other pays 0.10%. The low-volume customer is subsidising the high-volume one. This model holds when the portfolio skews towards smaller customers. As the business matures and wins larger customers, the subsidy runs in the wrong direction, and the unit economics deteriorate.
The third factor is stickiness. In SaaS, subscription pricing reinforces lock-in over time. The longer a customer stays, the more data and workflows accumulate within the product. This makes it more expensive for a long-standing customer to switch than for a new one. And this makes subscriptions attractive. The subscription pricing and product stickiness reinforce each other, creating a flywheel. In payments, this lock-in effect does not exist. Stickiness in payments comes from factors that are unaffected by the pricing model. A customer who has been on a payments subscription for three years is no harder to lose than one who signed up last quarter.
What does this mean for a payments business?
Revolut Business and Wise have taken opposing positions on this issue. Revolut offers four subscription tiers, each with different limits on free FX transfers. Wise uses a purely variable model: you pay per transfer and nothing else. Both have been successful, but for very different reasons.
But Revolut does not sell just a payments product. It sells an entire platform: cards, expense management, approval workflows, accounting integrations and analytics. Many of Revolut’s subscribers use it primarily for spend controls and expense tooling, not for FX transfers. Their international payment usage is occasional. The subscription economics work because the cost of heavy FX users is offset by subscribers who rarely use the transfer feature.
Wise’s portfolio has no such cross-subsidy. Every customer is there specifically for FX usage. They will all maximise usage and optimise their per-transaction cost. The FX product does not give Wise the customer mix that makes subscription economics viable. This is why Wise charges per transfer and has not tried a flat subscription.
The implication for a pure-play cross-border payments company is straightforward. Replicating Revolut’s subscription model without Revolut’s product breadth means attracting all the heavy FX users and none of the casual subscribers to offset them. The economics will fail.
The only scenario where subscription pricing makes sense in payments is when pricing is mainly for platform capabilities and not transaction volume. A multi-currency treasury dashboard, an approval workflow engine, and a compliance reporting tool are all examples. Here, the subscription provides access to fixed-cost products and not to variable-cost processing. That makes it a viable model. But bundling transaction volume in a subscription and hoping the mix works out does not.
Subscription pricing looks glamorous and modern. But it is a margin problem disguised in a fancy dress.
