Why Adyen has Partnered with Medius for Corporate Cashback

Medius, a leading automation and spend management platform,that processes 300 billion dollars in annual spend across more than 4,000 customers in 116 countries, has long focused on eliminating friction from accounts payable workflows. Adyen, meanwhile, is not your typical payments company. It sits at the infrastructure layer of global commerce as the engine behind transactions for some of the most operationally complex enterprises in the world.
What draws these two together is less about feature overlap and more about where each one stops. Adyen is exceptional at moving money which is fast, securely, across borders. But it does not live inside the back office. Medius does. Through its acquisition of Expensya, it has woven expense management directly into its AP platform, meaning the full spend journey, from card swipe to ledger entry, now runs through a single connected system.
Together, they are addressing a problem that has persisted across finance departments for years: the gap between the moment an employee swipes a corporate card and the moment that transaction lands are reconciled and coded in the general ledger.

At the heart of this partnership is a corporate cashback rewards programme built specifically for business card transactions. Launching initially in EU and UK markets in Q1 2026, with a planned expansion into the US later in the year, the program allows customers to earn up to 0.5% back on all card spend.

That figure might sound modest in isolation, but consider what it means at scale. For a mid-sized enterprise processing several million in annual card spend, monthly rebates credited directly to customer invoices translate into a tangible, recurring reduction in operating costs, delivered without any additional SaaS fee.

The corporate cashback solutions stack goes further than this. Key capabilities include:
- Card issued in Native European Currencies,eliminating foreign exchange fees for intra-regional transactions.
- Compatibility with Apple Pay and Google Wallet, alongside physical cards for teams that require them.
- Automated expense tracking with every transaction captured, coded, and reconciled in real time.
- AI-driven fraud prevention integrated directly onto the payment Infrastructure.
- No additional Saas fee, keeping total cost of ownership predictable

For CFOs navigating tightening budgets and compliance mandates, the appeal here is straightforward: a corporate card programme that pays back while simultaneously eliminating the manual overhead that has historically plagued expense reporting.

For CTOs, the architecture of this solution is equally relevant. The integration between Adyen's issuing infrastructure and Medius's Expensya platform means there is no fragmented data pipeline to maintain, no middleware to troubleshoot, and no separate vendor relationships to manage. Every transaction flows automatically into existing accounting workflows.

For CXOs thinking about enterprise-wide transformation, the signal here is broader still. Adyen is positioning itself not just as a payments processor but as an embedded financial partner, one that sits inside the operational workflows that drive a company's spending behaviour.

For Medius, moving into card issuance represents a logical extension of its existing automation capabilities. The company has spent years digitising the invoice-to-payment cycle. Adding a card product that is native to that workflow, rather than bolted on from a separate vendor, closes the loop on spend management in a way that purely software-based competitors cannot easily replicate.

For Adyen, the Medius deal deepens its reach into corporate spend management without requiring it to build accounts payable capabilities from scratch. By embedding itself into Medius's existing customer base of over 4,000 businesses, Adyen gains immediate distribution across a segment it has been deliberately targeting: finance departments seeking to consolidate their technology stack.

One persistent challenge in corporate card programmes is employee adoption. Without it, spend policies go unenforced, audit trails grow incomplete, and the compliance case for any card programme weakens considerably.

The Adyen Medius model addresses this directly, not through mandates, but through incentives. When a card automatically eliminates the administrative burden of expense reporting while simultaneously earning cashback on every transaction, the motivation to use it consistently is built in. Higher adoption produces higher compliance, which is precisely what finance teams need to satisfy internal audit requirements and enforce spend governance at scale. For a CFO defending spend controls to the board, that is not a minor benefit, but a structural safeguard.

The EU and UK launch in Q1 2026 is the starting point, not the full picture. US expansion follows later in the year, bringing these corporate cashback solutions into one of the world's largest enterprise spending markets.

For finance and technology leaders evaluating their spend management infrastructure, the Adyen Medius Partnership is worth examining now rather than after the US rollout.

The corporate card and expense management market has long been anchored by American Express, JPMorgan, and SAP Concur. The Adyen Medius programme pays companies back for using it, with no additional fees on top. For procurement teams comparing total cost of ownership, that is a genuinely different conversation.
