Adyen Review →WePay Review →Adyen Pricing →WePay Pricing →

Two companies that keep acquiring in-house. Adyen does it as an independent, publicly listed payments firm, with one contract covering the gateway, processing and acquiring across 30+ markets. WePay does it as part of J.P. Morgan, which bought it in 2017: the bank onboards and verifies sub-merchants, takes on compliance, and runs the volume through its own acquiring, mainly in the US.

Global Reach	10	4	Adyen leads significantly (10 vs 4). Local acquiring licenses in 30+ markets reducing decline rates and cross-border fees. WePay: Primarily US market; limited international availability
Recurring Billing	6	5	Adyen scores slightly higher (6 vs 5). Subscription management available but not the platform's primary focus; better at one-time payments. WePay: Basic recurring support through tokenization; not a dedicated billing platform

Adyen vs WePay: What ISVs Need to Know

Choosing between Adyen and WePay for embedded payments is a decision that directly impacts your ISV’s revenue model, merchant experience, and technical architecture. This comparison breaks down where each platform excels from an ISV integration perspective.

Key Differences for ISVs

The most important distinction between Adyen and WePay comes down to how each platform approaches ISV payment facilitation. Adyen and WePay take fundamentally different approaches to merchant onboarding, revenue sharing, and platform integration — and those differences matter when you’re building payments into your software.

Integration architecture varies significantly between the two. ISVs evaluating Adyen vs WePay should consider how each platform handles sub-merchant onboarding, payment splitting, and settlement timing. The right choice depends on your specific vertical, transaction volumes, and how much control you need over the merchant payment experience.

Pricing and revenue economics also differ. ISVs earn money from embedded payments through the spread between what they charge merchants and what the processor charges them. The pricing model each platform uses — flat-rate, interchange-plus, or custom — directly affects your payment revenue per transaction.

Which Platform Fits Your ISV?

The best choice between Adyen and WePay depends on your ISV’s specific requirements:

Transaction volume: Higher-volume ISVs may benefit from interchange-plus pricing, while lower-volume platforms often prefer flat-rate simplicity
Merchant type: B2B merchants have different payment needs than consumer-facing businesses
Geographic scope: International payment support varies significantly between providers
Integration depth: Some ISVs need white-label checkout while others are fine with co-branded experiences
Revenue model: How much of the payment margin you want to capture determines which platform’s economics work better

The ISV Payment Integration Perspective

For ISVs evaluating Adyen vs WePay, the comparison shouldn’t stop at processing fees. Consider the total cost of integration, ongoing maintenance, and the revenue opportunity from embedded payments. The platform that generates the most payment revenue for your ISV while providing the best merchant experience is the right choice — and that calculation is different for every software company.

Evaluate both platforms against your specific use case. Request ISV-specific pricing from each, and compare the total economics including setup costs, per-transaction revenue, and the engineering investment required to integrate and maintain each platform.
