Which Is Best: All-In-One Payments or Flexible Orchestration?

The payment processing landscape presents businesses with a critical decision: should you choose an integrated all-in-one provider or a flexible orchestration platform that connects you to multiple payment partners? This fundamental choice shapes everything from your development timeline to your long-term cost structure and global expansion capabilities.

Stripe represents the integrated approach—a complete payment service provider that handles everything from gateway functions to fraud prevention within a single, developer-friendly platform. With $1.4 trillion in annual processing volume as of 2024, Stripe has proven its ability to scale with businesses from startup to enterprise level, offering the convenience of unified billing, comprehensive documentation, and rapid deployment.

ACI Enterprise Payments Platform takes the orchestration route, functioning as an intelligent layer that connects your business to multiple payment providers simultaneously. Rather than processing payments directly, ACI optimizes your payment strategy by routing transactions to the best-performing provider for each specific transaction. According to research by ACI Worldwide and Edgar, Dunn & Company, 85% of merchants using multi-acquiring strategies see conversion rate increases, with 23% achieving improvements over 10%.

The choice between these approaches isn’t just technical—it’s strategic. Do you value the simplicity and speed of a single integration, or do you need the flexibility and optimization that comes from managing multiple payment relationships? This comparison will examine both platforms in detail to help you determine which approach aligns with your business objectives.

Key Takeaways

• Stripe excels in providing a developer-friendly environment and a variety of features for e-commerce and subscription services.
• ACI Enterprise Payments Platform offers a robust payment orchestration solution featuring flexibility and multi-acquirer capabilities.
• Key differences lie in integration options, customer support, reporting features, and applicable use cases, which influence the choice between the two platforms.

Payment Gateway Overview

A payment gateway serves as the secure bridge between a customer’s payment method and the payment processor that handles the actual fund transfer. It encrypts and transmits payment data from the checkout page or point-of-sale system to the processor, which then communicates with banks or card networks to authorize and settle transactions.

Modern gateways include additional functions such as tokenization for secure card-on-file storage, fraud screening capabilities, and support for diverse payment methods—ranging from traditional credit/debit cards to digital wallets and region-specific payment options.

Many payment service providers offer combined gateway and processor services in one integrated package. This streamlined approach reduces complexity and accelerates implementation, though it means relying on a single provider’s infrastructure and pricing. Companies requiring greater control over their payment strategy often explore orchestration platforms that offer multi-provider connectivity.

Payment Orchestration Overview

While payment processors and gateways handle the mechanics of moving money and authorizing transactions, a payment orchestration platform (POP) adds a strategic control layer above them. Through a single integration point, a POP connects merchants to multiple payment service providers, gateways, and alternative payment methods.

This approach enables intelligent transaction routing based on factors like cost optimization, geographic considerations, provider performance metrics, redundancy requirements, or other business rules. For instance, a POP can direct European card transactions to one acquirer for optimal rates while routing U.S. transactions to another for better approval rates.

Orchestration reduces reliance on any single provider, improves resilience against service disruptions, and can increase authorization rates by routing to the most suitable PSP in real-time. It also simplifies market expansion by making it easier to add local payment methods without re-engineering existing checkout systems.

Stripe

Stripe has become synonymous with modern online payments, transforming how developers integrate payment functionality into websites and applications. Rather than wrestling with complex banking relationships and compliance requirements, businesses can begin accepting payments within hours of signing up.

What Is Stripe?

Stripe revolutionized online payments by making complex payment infrastructure accessible through simple APIs. Founded in 2010, the company has grown to serve millions of businesses worldwide, from individual creators selling digital products to Fortune 500 companies managing global commerce operations. Stripe handles the technical complexity of payment processing while giving developers the flexibility to create custom payment experiences.

How Does Stripe Work?

Behind Stripe’s simple integration lies sophisticated payment infrastructure. When customers complete purchases, Stripe securely captures their payment information, performs real-time fraud analysis, and routes transactions through banking networks for authorization. The platform maintains PCI compliance on behalf of merchants, handles currency conversion for international transactions, and provides detailed reporting on all payment activity.

What sets Stripe apart is its focus on the developer experience. Instead of lengthy integration projects, businesses can accept their first payment using just a few lines of code. The platform then scales automatically, handling everything from small transactions to high-volume enterprise processing without requiring infrastructure changes.

ACI Enterprise Payments Platform

While most businesses begin their payment journey with a single provider, growing companies often encounter limitations in cost optimization, approval rates, or geographic coverage. ACI’s Enterprise Payments Platform addresses these challenges by sitting above multiple payment providers, intelligently deciding where to route each transaction for optimal results.

What Is the ACI Enterprise Payments Platform?

ACI takes a fundamentally different approach to payment processing. Instead of handling transactions directly, ACI creates an intelligent routing layer that connects businesses to multiple payment providers simultaneously. This orchestration model allows companies to optimize each transaction based on factors like cost, approval likelihood, and geographic performance.

Think of ACI as a sophisticated traffic management system for payments. It evaluates each transaction in real-time and selects the optimal path through its network of connected providers. Research shows this approach delivers measurable results—85% of merchants implementing multi-acquiring strategies report conversion rate improvements, with nearly a quarter seeing increases exceeding 10%.

How Does ACI Work?

ACI’s orchestration engine analyzes each transaction across multiple dimensions before routing it to the optimal provider. The platform considers factors like the customer’s location, card type, transaction amount, and real-time provider performance data. If one provider is experiencing issues or has higher decline rates for specific transaction types, ACI automatically routes to alternatives.

The system continuously learns from transaction outcomes, refining its routing algorithms to improve performance over time. This intelligence extends beyond simple failover—ACI actively optimizes for business objectives like maximizing revenue, minimizing costs, or improving customer experience. The platform handles all the technical complexity while providing businesses with detailed analytics on provider performance and routing decisions.
