Checkout Picks for Stripe, Mollie, Adyen, and SaaS Billing

Online payments are the backbone of every digital business. The choice of payment provider directly impacts your checkout conversion, cost per transaction, and the payment methods you can offer to customers. In the European and Dutch market iDEAL support is essential because over 70 percent of online payments in the Netherlands go through this method. But as soon as you operate internationally or use subscription models, you need broader support for credit cards, SEPA direct debit, and local payment methods from other countries. In 2026 embedded finance is a growing trend: payment platforms increasingly offer invoicing, tax calculation, and subscription management as integrated services. This blurs the line between payment provider and financial platform. The question is no longer just which payment methods you want to support, but how deeply you want to integrate your payment flow into your business processes. We integrate payment systems into client projects weekly and evaluate five platforms on European market support, developer experience, cost structure, and scalability.

How did we select these tools?

We integrated each payment platform into a production webshop and measured checkout conversion, transaction speed, refund handling time, and API documentation quality. Costs were calculated based on 5,000 monthly transactions with an average order value of 75 euros.

How do we evaluate these tools?

• Support for European payment methods including iDEAL, Bancontact, SEPA direct debit, and credit cards with strong checkout conversion rates
• Developer experience and API documentation quality, including SDK support, sandbox environments, and speed of integration into existing codebases
• Transaction costs and pricing model transparency, including hidden fees, volume discounts, and the total cost of ownership per month
• Scalability and support for international payments in multiple currencies with local payment methods per country and region
• Fraud prevention and security features, including machine learning detection, 3D Secure support, and PCI DSS compliance without extra configuration
• Subscription and recurring billing capabilities, including plan management, prorations, trial periods, and automated invoicing for SaaS business models

1. Stripe

The most developer-friendly payment platform in the world with an API that is considered the gold standard in the industry. Stripe supports over 135 currencies and a wide range of payment methods from credit cards to iDEAL and local alternatives. Advanced products like Stripe Connect for marketplaces, Billing for subscriptions, and Revenue Recognition for accounting make it a complete financial platform. Radar provides AI-powered fraud prevention that improves with every transaction processed.

2. Mollie

Dutch payment platform specifically designed for the European market with the simplest iDEAL integration in the industry. Mollie offers a clear dashboard, transparent per-transaction pricing without monthly fees, and support for all popular European payment methods. The platform integrates in minutes thanks to excellent plugins for WooCommerce, Shopify, and Magento. For Dutch webshops and SaaS companies that want to start quickly without complex configuration, Mollie is often the ideal choice.

3. Adyen

Enterprise payment platform from Amsterdam offering unified commerce for online, in-store, and mobile payments in a single system. Adyen is used by major companies like Uber, Spotify, and Booking.com and provides direct connections to card networks for lower costs at high volume. The RevenueProtect module delivers AI-powered fraud prevention and platform-wide analytics provide insight into payment behavior across all channels. Adyen is the choice for enterprise organizations processing millions of transactions per month.

4. Paddle

Merchant of Record platform that handles payments, global tax compliance, and regulatory requirements so you do not have to. Paddle is specifically designed for SaaS companies selling internationally who want to avoid managing VAT obligations, sales tax, and compliance across dozens of jurisdictions themselves. The platform handles checkout optimization, subscription management with usage-based billing, and automated invoicing. For digital product companies that want to focus on building rather than financial operations, Paddle removes significant operational complexity.

5. MultiSafepay

Dutch payment service provider combining a broad range of payment methods with e-commerce solutions for the European market. MultiSafepay offers standard payment processing alongside integrated gift card support, second chance emails for abandoned payments, and a customizable checkout page. The platform is popular among medium-sized webshops that need more flexibility than Mollie but want less complexity than Stripe or Adyen. Good plugins are available for all major webshop platforms in the market.
