Why Platforms Look for Checkout.com Alternatives
Checkout.com is a legitimate enterprise PSP. It has strong acquiring infrastructure, intelligent routing for authorisation rate optimisation, and global coverage that makes it a credible choice for large direct merchants. For e-commerce businesses and enterprise brands processing at volume, it competes seriously.
Checkout.com's core business is merchants that accept payments directly, and it also offers Checkout.com Platforms for businesses that onboard sub-entities. Every sub-entity processes on Checkout.com, which is where platforms with varied merchant requirements run into walls.
Single-PSP Architecture
Every transaction processed through Checkout.com goes through Checkout.com. There are no multi-PSP options, no ability for a platform's merchants to bring existing gateway relationships, and no flexibility to route different merchant segments through different processors. If you have an enterprise customer who has spent months negotiating a Worldpay contract with interchange-plus pricing, Checkout.com cannot accommodate them. The infrastructure assumes a single processor, and that processor is Checkout.com.
For direct merchants, this is a non-issue. For platforms serving dozens or hundreds of merchants with varied requirements, it is a structural constraint that creates friction with every enterprise deal.
Platform Tooling on One Processor
Checkout.com Platforms onboards sub-entities through Hosted Onboarding or its API. Every sub-entity processes on Checkout.com, so the tooling does not help merchants who need a different PSP.
Pricing Opacity
Checkout.com's pricing is enterprise-custom. There is no published rate card. Prospective customers enter a sales process and receive a commercial proposal based on negotiated terms. For platforms evaluating infrastructure options on a tight timeline, this creates friction: you cannot model unit economics without getting to the end of a sales cycle.
Voice Channel Gap
Checkout.com covers online checkout, payment links and agent-keyed MOTO payments, and it has adopted OpenAI's Agentic Commerce Protocol. What it does not offer is keypad card capture inside a live call, for a person or an AI agent. Platforms that need it add a separate voice payment provider, with its own PCI surface and reporting.
What to Evaluate in an Alternative
Not every alternative addresses the same problems. Before committing to a new direction, clarify which constraints matter most for your platform:
PSP flexibility: If your merchants have existing gateway contracts or will mandate specific processors, you need PSP-neutral infrastructure, not another single-PSP solution. Swapping Checkout.com lock-in for Stripe lock-in solves a vendor problem, not an architecture problem.
White-label platform tooling: Merchant onboarding, merchant portal, and checkout experiences should look and feel like your platform. Evaluate whether an alternative provides genuinely white-label tooling or just co-branded overlays.
Channel coverage: List the payment channels you need today and the ones you are likely to need in the next two years. Voice payments, AI agents, and payment links are increasingly part of platform RFPs. Rebuilding infrastructure for each new channel is expensive.
Compliance posture: Decide how far you want to limit your PCI scope. Card data that never touches your systems changes both your engineering requirements and your security assessment.
Pricing transparency: You need to model unit economics before committing to infrastructure. Prioritise alternatives that publish rates or provide clear pricing frameworks early in the evaluation process.
Time to market: If deals are waiting on your payment feature, evaluate integration timelines honestly. A months-long enterprise integration process has a real cost in delayed revenue.
The Alternatives
1. PSP-Neutral Payment Layer (Shuttle)
What it is: A payment infrastructure layer that embeds multi-PSP payment acceptance into your platform. Shuttle connects to 40+ gateways, including Checkout.com, and provides white-label checkout, merchant onboarding, merchant portal, and multi-channel support through a single integration.
Strengths:
PSP-neutral by design: Merchants choose their preferred gateway or you assign one. Enterprise customers with their own Checkout.com, Stripe or Worldpay Access account can connect it.
White-label everything: Checkout flows, onboarding journeys, and merchant portals are branded as your platform, not as Shuttle.
Multi-channel: Embedded checkout, voice payments, IVR capture, payment links, chat, and AI agent payments through a unified integration.
Certifications: PCI DSS Level 1 certified, ISO 27001 and SOC 2. Your PCI scope is materially reduced.
Pre-built components: designed for platform integration, not a custom engineering engagement.
Checkout.com as an option, not a mandate: Merchants with their own Checkout.com account can keep using it. Merchants who need something different get it.
Limitations:
Shuttle has less brand recognition than Stripe or Adyen
No transaction-level routing optimisation, which dedicated orchestration middleware offers
Best for: Platforms that need to embed payments for their merchant base, support PSP flexibility, and reach market quickly, without building or maintaining payment infrastructure themselves.
2. Adyen for Platforms
What it is: Adyen's solution for platforms and marketplaces. A unified commerce infrastructure that handles sub-merchant onboarding, split settlements, and multi-party payment flows at enterprise scale.
Strengths:
Enterprise-grade global acquiring with strong authorisation rates
Unified online and in-store (POS) coverage
Robust compliance and KYC/KYB infrastructure for merchant onboarding
Deep reporting and reconciliation tooling
Strong multi-currency and cross-border support
Limitations:
Single-PSP lock-in. Every merchant on Adyen for Platforms processes through Adyen. PSP flexibility does not exist within the product.
Sales-led go-to-market, with a minimum invoice by industry
No keypad card capture inside voice calls; Pay by Link and Adyen Agentic cover links and AI commerce
Components can be styled to your brand, but every sub-merchant is on Adyen
Integration complexity requires significant engineering investment
Best for: Enterprise platforms with committed Adyen relationships, high transaction volumes, and merchants who are content processing exclusively through Adyen. Not suitable for platforms with PSP flexibility requirements.
3. Stripe Connect
What it is: Stripe's platform payments product. An aggregator model where the platform holds a master account and merchants connect as sub-accounts. The most widely adopted starting point for platform payment features.
Strengths:
Best-in-class developer experience and API documentation
Fast time to market
Self-serve access and transparent published pricing
Large ecosystem of pre-built integrations, plugins, and tools
Strong hosted onboarding (Express and Standard accounts)
Reliable uptime and global coverage in most major markets
Limitations:
Single-PSP lock-in: same structural problem as Checkout.com. Stripe Connect means Stripe as the processor. Enterprise customers cannot bring their existing gateway relationships.
Agentic tools serve online commerce, not card capture inside a voice call
Geographic gaps in Southeast Asia, Africa, and parts of Latin America
Pricing pressure at high volume relative to negotiated enterprise rates
Embedded components can be styled to your brand, but every merchant is on Stripe
Best for: Platforms prioritising developer experience and speed to market, comfortable with Stripe as the sole processor for all merchants.
4. Building In-House
What it is: Directly integrating with one or more PSPs, building your own merchant onboarding flow, portal, and checkout infrastructure, either to become a registered PayFac or to aggregate under a master merchant account.
Strengths:
Full control over the merchant experience
Maximum flexibility in PSP selection and routing logic
Highest per-transaction economics if you operate as a PayFac
Limitations:
Time and cost. A production-ready platform payments stack (with compliant onboarding, white-label checkout, merchant portal, reconciliation, and PCI-scoped architecture) takes significant time and engineering headcount.
PCI obligations. Building in-house means owning PCI scope. PCI DSS compliance for a platform is an annual audit commitment, not a one-time certification.
Regulatory complexity. Depending on your model, operating as a PayFac introduces licensing and compliance obligations that compound as your merchant base grows.
Ongoing maintenance. Every PSP API update, every compliance requirement change, every new payment method your merchants want: these become your engineering team's problem indefinitely.
Distraction from core product. Payments infrastructure engineering is a significant sustained investment in something that is not your product.
Best for: Platforms where payments are the core product and you have the engineering capacity, compliance expertise, and timeline to do it properly. Not a realistic near-term option for most platforms.

Making the Decision
Checkout.com may still be the right choice if:
You are a direct merchant (not a platform) with high transaction volume optimising for authorisation rates
You only need online checkout and are not embedding payments for third-party merchants
You have the budget for enterprise-custom pricing and the timeline for a sales-led process
Your volume justifies the commercial negotiation cycle
Look at alternatives if:
You are building a platform that embeds payment acceptance for your customers
Any merchant will require a specific PSP or has an existing gateway contract
You need card capture inside voice calls
You need white-label merchant onboarding and a portal that looks like your product
You need to model unit economics before committing to infrastructure
You want to limit the PCI scope you carry in-house
The consistent pattern: Checkout.com is a strong PSP, and its platform product keeps every merchant on Checkout.com. The gap is structural, not a configuration problem.
FAQ
Can I keep using Checkout.com for existing merchants while adding other PSPs for new ones? Yes. Shuttle supports Checkout.com as one of its 40+ gateways. Merchants with their own Checkout.com account can connect it to Shuttle, and new merchants, or those requiring a different PSP, are connected to the appropriate gateway. Saved cards stay with the gateway that stored them.
Is Checkout.com genuinely more expensive than alternatives, or is that just perception? Checkout.com uses custom pricing, so direct comparison is difficult without going through their sales process. Whether its rates are competitive depends on the terms negotiated, your volume profile and what you are comparing them against.
How does Checkout.com compare to Adyen for platform use cases? Both have platform products, and both keep every sub-merchant on their own network. Checkout.com is generally considered stronger on intelligent routing and authorisation rate optimisation. Adyen for Platforms has more developed infrastructure specifically for multi-party payment flows and sub-merchant management. Neither solves PSP flexibility. For platforms, the more relevant question is whether either of these single-PSP solutions fits the use case, or whether PSP-neutral infrastructure is the right architecture. See the Shuttle vs Adyen comparison for a detailed breakdown.
What happens to my PCI compliance obligations if I move to a platform payment layer? With a fully-hosted, PCI DSS Level 1 certified payment layer, your PCI scope drops sharply for the payment components handled by the provider. You are not storing, processing, or transmitting cardholder data in your own infrastructure. This is materially different from building integrations directly against PSP APIs, where your integration touchpoints can pull your platform into PCI scope. The specific scope reduction depends on your integration architecture. Your QSA can confirm the final scope.
Can a platform payment layer support voice payments and AI agent payments alongside online checkout? Yes. This is one of the primary reasons platforms evaluate PSP-neutral layers over single-PSP solutions. Shuttle covers embedded checkout, voice payments (including IVR capture), payment links, chat, and AI agent payments through a single integration. Adding a new payment channel does not require a separate PSP integration or a separate PCI surface.
How long does it realistically take to go live with a platform payment layer? The timeline depends on integration complexity and how many pre-built components you use. Using Shuttle's pre-built checkout, onboarding and portal components cuts the build; custom integrations with complex existing infrastructure take longer.
