Stripe vs Adyen vs Checkout.com vs GetPayment: The Ultimate Comparison for High-Volume Ecommerce

Introduction: Choosing the Right Payment Stack at Scale

At low volume, almost any payment provider works.

At scale, your payment system becomes one of your most important revenue drivers.

The difference between providers is no longer just about features.

It is about:

• Approval rates
• Cost efficiency
• Risk exposure
• Scalability
• Global performance

Many businesses start with Stripe.

As they grow, they evaluate enterprise providers like Adyen and Checkout.com.

But increasingly, high-performance merchants are moving toward a different approach entirely.

This is where GetPayment vs Stripe vs Adyen vs Checkout.com becomes a critical comparison.

Because at scale, the question is not: "Which provider is best?"

It is: "Which system captures the most revenue?"

The 4 Payment Models Explained

Before comparing providers, it is important to understand that these solutions represent different models.

Stripe is an all-in-one payment processor designed for simplicity.

Adyen is a unified enterprise platform with global capabilities.

Checkout.com is a performance-focused processor with strong APIs.

GetPayment is not a processor — it is an optimization system that sits across multiple providers.

This distinction is critical.

Because you are not just choosing a provider.

You are choosing a strategy.

Stripe: The Best Starting Point, But Limited at Scale

Stripe is one of the easiest payment solutions to implement.

It offers:

• Fast onboarding
• Developer-friendly APIs
• Built-in fraud tools
• Subscription management

For startups and early-stage ecommerce, it is ideal.

Where Stripe Falls Short

As you scale, limitations become clear.

Stripe operates as a single-provider system.

This creates constraints:

• Fixed routing logic
• Limited approval optimization
• Strict risk controls
• Potential account instability

High-risk or high-volume merchants often experience:

• Account reviews
• Payment holds
• Increased declines

Stripe is excellent for simplicity, but not for optimization.

Adyen: Enterprise Power with a Unified System

Adyen is designed for large, global businesses.

It provides:

• Gateway and acquiring in one platform
• Global payment coverage
• Enterprise reporting
• Strong infrastructure

It is used by many major brands.

Strengths of Adyen

Adyen excels in:

• Global reach
• Enterprise scalability
• Unified reporting
• Reliability

It is a powerful system for businesses that want everything in one place.

Limitations of Adyen

Despite its strengths, Adyen still operates as a single ecosystem.

This means:

• Limited routing flexibility
• Dependence on one provider
• Less granular optimization

While strong, it does not fully unlock multi-acquirer advantages.

Checkout.com: Performance-Focused Processing

Checkout.com is positioned as a modern alternative to legacy enterprise providers.

It offers:

• Strong API performance
• Global acquiring
• Flexible integrations

It is popular among scaling ecommerce brands.

Strengths of Checkout.com

Checkout.com is known for:

• High-performance processing
• Developer flexibility
• Competitive approval rates

It is a strong option for businesses moving beyond Stripe.

Limitations of Checkout.com

However, it still follows a single-provider model.

This creates similar constraints:

• Limited routing control
• Dependence on one acquiring network
• Less flexibility compared to multi-provider systems

GetPayment: The Optimization Layer for Maximum Performance

GetPayment is fundamentally different.

It is not a processor.

It is a system that optimizes your entire payment stack.

Instead of relying on one provider, it enables you to:

• Use multiple acquirers
• Route transactions dynamically
• Optimize approvals and costs
• Build a resilient infrastructure

This is a different approach.

And at scale, it is often the most effective.

The Core Difference: Single Provider vs Multi-Acquirer Optimization

Stripe, Adyen, and Checkout.com all share one limitation.

They are single-provider systems.

Even when powerful, they are constrained by their own infrastructure.

GetPayment removes this limitation.

It allows you to:

• Route transactions across multiple providers
• Optimize based on performance
• Reduce dependency on any single system

This creates a fundamentally more powerful setup.

Approval Rates: Where the Real Money Is Made

Approval rates are one of the most important metrics in ecommerce.

A small increase can lead to significant revenue gains.

Stripe, Adyen, and Checkout.com offer solid baseline approvals.

But they are limited by:

• Fixed routing
• Single acquiring networks

GetPayment improves approval rates by:

• Using multiple acquirers
• Routing transactions dynamically
• Optimizing by geography and risk

This often leads to higher overall performance.

Cost Structure and Margin Optimization

Stripe uses flat pricing.

Adyen and Checkout.com offer interchange-plus models.

While these can be competitive, they are still limited by:

• Single-provider pricing
• Less negotiation leverage

GetPayment improves cost efficiency by:

• Introducing competition between providers
• Optimizing interchange
• Reducing unnecessary fees

At scale, this can significantly improve margins.

Risk and Account Stability

Risk is a major concern for scaling businesses.

Stripe is known for strict controls.

Adyen and Checkout.com are more flexible but still represent single points of dependency.

GetPayment reduces risk by:

• Distributing volume across multiple providers
• Avoiding reliance on one system
• Maintaining processing continuity

This creates a more stable environment.

Global Performance and Cross-Border Optimization

All three providers support global payments.

However, optimization is limited to their networks.

GetPayment enhances global performance by:

• Using multiple local acquirers
• Routing transactions by region
• Reducing cross-border inefficiencies

This leads to better approvals and lower costs internationally.

Flexibility and Control

Stripe offers limited flexibility.

Adyen and Checkout.com offer more, but still within their ecosystems.

GetPayment provides full control.

You can:

• Customize routing logic
• Integrate multiple providers
• Adapt to performance changes

This flexibility is critical at scale.

Redundancy and Failover

Single-provider systems carry risk.

If the provider experiences issues, your revenue is affected.

GetPayment builds redundancy by design.

You can:

• Failover between providers
• Maintain uptime
• Protect revenue streams

This is a major advantage for enterprise businesses.
