Start with your markets and sales channels
Stripe and Adyen should be compared against the countries where your entities operate, the payment methods your customers use, and the channels through which they buy. A company collecting subscription payments online has a different implementation from a retailer connecting stores, an app, and an ecommerce site.
Stripe documents online integration choices and in-person payment options. Adyen documents omnichannel use cases and a catalog of payment methods. Those sources establish areas to investigate, not universal coverage for every business. Obtain confirmation for the actual merchant entity, customer market, currency, and channel combinations that matter to your rollout.

Describe the account structure before the checkout
List the legal entities selling to customers and the accounts expected to receive settlement. Then distinguish stores, brands, websites, and reporting units from those legal entities. A group may want a consolidated management view while still needing separate merchant agreements and accounting records.
Ask each provider to diagram the proposed merchant and payment-account structure. Include who can view activity, issue refunds, change bank details, and create new locations. This design affects reconciliation and administration after launch. It also prevents a later discovery that a convenient operating label was being used as if it represented the legal seller or the bank account entitled to the funds.
Use a cross-channel customer journey
For a retailer, test an online order collected in a store, a partial return, and a refund handled by another location. For a digital business, test an initial purchase followed by a renewal and an updated payment method. Choose the journey your company actually needs; a broad omnichannel demonstration may be irrelevant to an online-only business.
Adyen publishes cross-channel use cases, while Stripe documents separate online and in-person integration routes. Ask the implementation team to show how the proposed systems connect orders, payment references, customer records, and refunds. A common payment provider does not by itself ensure that every store and ecommerce application shares the same usable identifiers.

Compare a country-and-channel requirement sheet
A short matrix makes coverage claims reviewable. Replace these examples with the actual launch markets and retain written confirmation from each finalist.
| Requirement | Confirmation needed |
|---|---|
| Merchant entity | Onboarding eligibility and the contracting arrangement |
| Customer market | Required methods, currencies, and authentication experience |
| Store payments | Supported devices, integration, and operational support |
| Online payments | Checkout design, failed-payment handling, and order references |
| Settlement | Bank account, currency, timing, reports, and adjustments |
| Expansion | What changes when another entity, market, or channel is added |
Make finance inspect the settlement files
Request sample reports for payments, refunds, fees, disputes, reserves where applicable, and payouts. Ask the accountant to explain one deposit using those records. Then include a payment created in one period and adjusted in another. The selected reporting arrangement should preserve the dates and references needed to reconcile both periods.
For an illustrative store group, a single day's sales may settle to several accounts or include activity from several trading days. Decide whether reconciliation is organized by entity, store, merchant account, currency, or payout. The dimensions need to be available consistently. A consolidated dashboard is useful for management, but it cannot replace the records that explain each legal entity's cash.
Include a location that closes after the rollout. Finance should still be able to find its original transactions, process an eligible refund, and explain later adjustments. Agree who retains access to those historical records when the store's operating users are removed.
Compare engineering and operational obligations
Ask who maintains checkout code, terminals, event processing, account configuration, and payment-method changes. Include customer-service procedures for refunds and disputed transactions. A payment integration has continuing work even when the processor operates the underlying infrastructure.
Evaluate a failure scenario as well: delayed events, an unavailable store connection, or a payment whose status is unclear. The team needs a documented way to check status and recover without charging twice or fulfilling an unpaid order. Obtain the support arrangement and escalation path in the proposal. Do not infer guaranteed resolution times from a broad enterprise-service description.
Choose from the supported operating design
Compare processing, optional services, devices, implementation, support, and ongoing engineering on a common transaction sample. Include local methods, currency conversion, refunds, and the expected mix of online and in-person sales. Avoid using a published acceptance-rate claim as a forecast for a different customer population.
The stronger proposal is the one that confirms required coverage, demonstrates the customer journey, and produces finance records the business can reconcile. Stripe or Adyen may meet that brief. The choice should identify what makes the proposed design suitable for your entities and channels, and what additional work will be needed when the business expands.
