Payment Orchestration Alternatives for Platforms

Why Platforms Look Beyond Payment Orchestration

Payment orchestration platforms solve a real problem, for merchants. They let large enterprises route transactions across multiple PSPs, optimise authorisation rates, and manage tokens in a single vault. If you're a merchant with three acquiring relationships and you want smart failover between them, orchestration is built for you.

But if you're a platform embedding payments for your merchants, orchestration solves the wrong problem. Here's why.

Orchestration Is Merchant-Facing, Not Platform-Facing

Primer, Spreedly and Gr4vy are designed first for merchants optimising their own payment stack: a single business, managing its own PSP relationships and provider selection. Gr4vy also sells a platforms product.

Platforms have a fundamentally different architecture. You're not optimising one merchant's transactions; you're onboarding hundreds or thousands of merchants, each with their own processing needs, each expecting payments to feel like part of your product. Most orchestration is built around a single entity controlling the payment flow, though Gr4vy for Platforms extends it to sub-merchants.

Few Platform Tools

Orchestration gives you APIs and, at some vendors, checkout components (Spreedly Express, Gr4vy Embed). What it generally doesn't give you is a merchant onboarding flow and a branded portal where your merchants manage refunds and view transactions. You build those yourself, or you don't offer them.

For platforms, this is the difference between launching a payments feature and launching a multi-quarter engineering project.

No In-Call Capture

Some orchestrators now offer payment links (Gr4vy) and agentic commerce (Spreedly, Gr4vy). What orchestration does not cover is card capture inside a phone call, for a person or an AI agent.

You'd need a separate voice payment provider, with its own PCI surface and engineering overhead.

Heavy Integration Burden

Orchestration platforms are middleware. Sophisticated middleware, but middleware nonetheless. Primer's no-code workflow builder reduces some of this, but you're still assembling infrastructure, not deploying a product.

For platforms on a roadmap, "months of payment integration" is a hard sell to your product team.

You're Buying Building Blocks, Not a Product

This is the core issue. Orchestration gives you routing, tokenisation and PSP connectivity. Much of the rest, such as merchant onboarding, reporting, a merchant portal and in-call capture, is your problem.

For a large enterprise with a payments engineering team, that's fine. For a platform that wants to offer embedded payments as a feature, it's a distraction from your core product.

Orchestration vs What Platforms Actually Need

The mismatch becomes clear when you map orchestration capabilities against platform requirements:

What orchestration provides:

• Multi-PSP routing and failover

• PSP-agnostic tokenisation

• Authorisation rate optimisation

• A single API abstraction over multiple gateways

What platforms actually need:

• White-label checkout embedded in their product

• Merchant onboarding that works out of the box

• A merchant portal branded as their platform

• Multi-channel payment capture (voice, links, AI agents)

• Limited PCI scope across channels

• Sub-merchant management at scale

Orchestration addresses the first column. Platforms need both columns, and the second column is where the real complexity lives.

The Alternatives

1. Stripe Connect

What it is: Stripe's purpose-built platform payments solution. Unlike orchestration, Connect is a complete product: onboarding, checkout, payouts, and reporting, all designed for platforms embedding payments for their merchants.

Strengths:

• Fast to integrate, with excellent documentation and developer experience

• Handles merchant onboarding (Express, Standard, and Custom account types)

• Built-in payouts, reporting, and dispute management

• Large ecosystem and community

Limitations:

• Single-PSP. Every Connected Account processes through Stripe. If an enterprise merchant has a Worldpay contract or needs a local acquirer in a market where Stripe is weak, you can't support them.

• Geographic gaps in some emerging markets

• No keypad card capture inside voice calls; payment links and agentic tools serve online commerce

• Pricing pressure at high volumes

Best for: Platforms that are happy with Stripe as their sole processor and don't need card capture inside voice calls.

2. Adyen for Platforms

What it is: Adyen's platform and marketplace solution, with sub-merchants onboarded and processing on Adyen.

Strengths:

• Strong global acquiring coverage, especially for enterprise

• Unified commerce (online + in-store on one platform)

• Good multi-currency and local payment method support

• Enterprise-grade infrastructure and risk management

Limitations:

• Single-PSP. You've traded orchestration's complexity for Adyen lock-in. Merchants process through Adyen, with no flexibility for enterprise customers with existing PSP relationships.

• Enterprise-focused

• Sales-led, not self-serve

• Developer experience less polished than Stripe

Best for: Enterprise platforms committed to Adyen as their sole processor, especially those needing unified commerce.

3. PayFac-as-a-Service (Payrix, Finix)

What it is: Managed PayFac infrastructure. You get merchant onboarding, underwriting, and higher payment margins without building a PayFac from scratch.

Strengths:

• More control over merchant pricing and underwriting

• Faster than building your own PayFac

Limitations:

• Typically single-PSP. Most PFaaS solutions process through a single acquirer.

• Compliance obligations vary by tier

• No in-call voice capture; payment links and in-person payments vary by provider

• Regulatory burden scales with your merchant base

Best for: Platforms where payment revenue is the primary business model and you want maximum margin, and you're willing to accept the compliance overhead.

4. PSP-Neutral Payment Layer (Shuttle)

What it is: A payment layer that connects platforms to many PSPs through one integration, combined with the platform-ready tools that orchestration lacks. White-label checkout, merchant onboarding, management portal, and multi-channel support through a single integration.

Strengths:

• PSP-neutral: 40+ gateways. Your merchants choose their PSP, or you assign one. Enterprise customers with their own Adyen, Checkout.com or Worldpay Access account can connect it.

• Multi-channel: Embedded checkout, voice payments, payment links, chat, and AI agent payments, all through the same integration. No separate PCI surfaces.

• White-label everything: Checkout, onboarding and merchant portal are branded as your platform.

• Certifications: PCI DSS Level 1 + ISO 27001 + SOC 2. Card data never touches your platform, which limits its PCI scope.

• Pre-built components: not a build project.

Limitations:

• No transaction-level routing optimisation: the gateway is set per merchant and per payment method, not chosen per transaction

• Newer entrant, with smaller brand recognition than Stripe or Adyen

Best for: Platforms that need multi-PSP flexibility, white-label tools, and multi-channel payment capture, without the engineering overhead of assembling it from orchestration building blocks.

What Orchestration Gets Right, and What It Misses

Credit where it's due. Payment orchestration platforms have pioneered genuinely valuable capabilities:

Smart routing: directing transactions to the PSP most likely to approve them based on card type, geography, BIN data, and historical performance. This measurably improves authorisation rates for merchants processing at scale.

PSP-agnostic tokenisation: storing card credentials in a vault that isn't tied to a single processor. Spreedly's vault, in particular, is a mature piece of infrastructure. This gives merchants portability: if you switch PSPs, your tokens come with you.

Redundancy: if one PSP goes down, an orchestration platform can fail transactions over to another connected PSP. For high-volume merchants, that resilience is critical.

These are real, valuable capabilities. But they're merchant capabilities, not platform capabilities.

A platform doesn't need to optimise its own authorisation rates; it needs to embed payment acceptance for hundreds of merchants. A platform doesn't need PSP-agnostic tokens for its own cards on file; it needs each merchant to be able to use their preferred PSP. A platform doesn't need failover between its own PSP connections; it needs white-label checkout, onboarding, and reporting that work out of the box.

Orchestration answers the question: "How do I optimise my payment stack?" Platforms are asking: "How do I offer payments to my customers?"

Different question. Different solution.

Comparison Matrix

Making the Decision

Orchestration might still be right if:

• You are a merchant (not a platform) optimising your own payment stack

• You have an engineering team dedicated to payments infrastructure

• You already have checkout, onboarding, and reporting built

• Your primary goal is authorisation rate optimisation across existing PSP relationships

Look at platform-ready alternatives if:

• You're a platform embedding payments for your merchants

• You need white-label checkout, onboarding, and merchant management

• You want multi-PSP flexibility without building everything yourself

• You need card capture inside voice calls

• Speed to market matters: deals are waiting

• You want to limit the PCI scope you carry

FAQ

Is Shuttle a payment orchestration platform? No. Shuttle is a payment layer built for platforms. Orchestration platforms are merchant-facing middleware that optimise routing between PSPs. Shuttle is platform-facing infrastructure that embeds multi-PSP payment acceptance (with white-label checkout, merchant onboarding, a branded portal, and multi-channel support) into your product. The multi-PSP flexibility overlaps, but the architecture and use case are fundamentally different.

Can I get multi-PSP without orchestration? Yes. Multi-PSP support doesn't require orchestration middleware. A PSP-neutral payment layer like Shuttle connects to 40+ gateways and lets each merchant use its own PSP, if it is one of them, without the integration complexity of orchestration. You get the PSP flexibility without having to build checkout, onboarding, and merchant management yourself.

What about routing optimisation? If your primary need is transaction-level smart routing (sending each transaction to the PSP most likely to approve it based on BIN data, geography, and historical performance), orchestration platforms are purpose-built for that. For most platforms, however, PSP-level routing (letting each merchant use their preferred gateway) delivers the flexibility they actually need. Transaction-level routing optimisation is a merchant concern, not typically a platform concern.

Should I use orchestration AND a payment layer? In theory, you could layer orchestration underneath a platform payment solution. In practice, it adds complexity and cost without clear benefit for most platforms. The multi-PSP connectivity that orchestration provides is already built into a PSP-neutral payment layer. You'd be paying for two abstraction layers that solve overlapping problems. The exception might be very large platforms with specific routing optimisation requirements at the individual transaction level, but that's a niche case.
