⚠ Switching Costs Are Real but Not AbsoluteModerate threat

Adyen's switching costs are genuine, but they are relative rather than absolute, and understanding the difference is key to sizing the moat honestly. The deep integration into a merchant's operations makes a wholesale rip-and-replace — removing Adyen entirely and re-integrating a single competitor everywhere — costly and unlikely, and that is a real source of stickiness. But because the largest merchants multi-source, keeping several providers integrated at once, the practical switching cost that matters is not the cost of a full replacement but the far lower cost of shifting volume among already-integrated providers — and that friction is modest. A merchant unhappy with Adyen's pricing or performance need not undertake a wholesale switch; it can simply route more volume to a competitor it already uses, at little cost, which sharply limits the protective power of the integration.

This distinction — deep switching costs against wholesale replacement, weak switching costs against marginal reallocation — is why the moat, though real, is narrow. It means Adyen is hard to remove entirely (durable) but easy to trim at the margin (contestable), so it must keep earning its share of each account through continued superior performance and competitive pricing rather than resting on the integration. The industry's push toward portability and standardization further softens switching costs over time, as it deliberately does across enterprise technology. Adyen's integration still matters greatly — it wins Adyen the position to capture the largest share of an account and makes it the hardest provider to displace fully — and for less sophisticated or single-provider merchants the switching costs are stronger. But an investor should recognize that against Adyen's core customers, the powerful multi-sourcing giants, the switching costs deter the big, wholesale move while permitting the small, marginal one — real protection against losing a customer entirely, limited protection against losing volume and pricing at the edge — which is the signature of a strong narrow moat rather than an impregnable wide one, and the reason Adyen must compete for its volume continually even within its stickiest accounts — where Stripe bids for the same flows¹.
