Unified Commerce (Online, In-Store, In-App)Narrow moat

One of Adyen's most valuable and differentiated capabilities is unified commerce: handling a merchant's payments identically across every channel — online checkout, physical stores, and in-app — on the same single platform, with the same data and the same capabilities. For a large retailer or restaurant chain that sells online, in physical locations, and through an app, this is genuinely powerful: it gives them one view of every customer and transaction regardless of channel, lets them offer experiences that span channels (buy online, return in store; recognize a customer across web and shop), and replaces a jumble of separate online and in-store payment providers with a single partner. Few competitors can match this, because doing it requires exactly the kind of single, full-stack platform Adyen built.

Unified commerce is a real growth engine and a genuine point of differentiation, especially against online-only players and against the fragmented incumbents who handle in-store and online through different systems. It extends Adyen's reach from pure e-commerce into the enormous physical-payments market, and it deepens its hold on merchants who consolidate all their channels onto Adyen. It plays directly to the single-platform advantage and is one of the clearest ways Adyen turns its architecture into commercial value. Candor requires noting that in-store payments is a harder, more established, more contested, and lower-margin market than online — dominated by entrenched incumbents with large installed bases of terminals and deep relationships — so Adyen's expansion into it, while real and growing, is a fight on tougher ground than its online heartland. Unified commerce is a genuine differentiator and a real growth driver that showcases the single-platform moat; but it takes Adyen into the harder half of payments, where the competition is more entrenched and the economics more demanding — terrain the 21–23% growth guidance leans on¹.
