TLDR
A sub-merchant is a business that accepts payments through a payment facilitator or platform instead of maintaining its own direct acquiring relationship.
What is a sub-merchant?
A sub-merchant is a business that accepts payments under the payment infrastructure and merchant account of another organisation, typically a payment facilitator (PayFac), marketplace, platform, or payment service provider.
Instead of establishing a direct relationship with an acquiring bank, the sub-merchant operates under the umbrella of the sponsoring platform, which manages payment processing, compliance, and merchant administration. Sub-merchants are common in marketplaces, SaaS platforms, platform businesses, and payment facilitator models.
How sub-merchants work
In a sub-merchant model, the platform or payment facilitator acts as the primary merchant relationship holder with the acquiring bank or payment providers. Individual businesses are onboarded as sub-merchants and can begin accepting payments through the platform's payment infrastructure. The platform typically handles payment processing, settlements, compliance, monitoring, and reporting, while the sub-merchant focuses on its products or services.
What is sub-merchant onboarding?
Sub-merchant onboarding is the process of registering, verifying, and approving a business before it can start accepting payments as a sub-merchant.
The exact process varies by provider and jurisdiction, but often includes:
- Business verification.
- Know Your Business checks.
- Ownership verification.
- Risk assessment.
- Compliance reviews.
- Account configuration.
Effective sub-merchant onboarding helps platforms scale merchant acquisition while meeting regulatory, card scheme, and risk management requirements.
Sub-merchant vs merchant
The main difference is the payment relationship structure. A traditional merchant typically has its own direct relationship with an acquirer or payment provider. A sub-merchant accepts payments through a platform or payment facilitator that manages this relationship on behalf of multiple businesses.
This model can simplify onboarding and payment acceptance for smaller businesses while allowing platforms to offer embedded payment capabilities to their users.
Why platforms use sub-merchant models
Sub-merchant models are widely used by marketplaces, software platforms, and payment facilitators because they make it easier to onboard and manage large numbers of businesses.
Benefits often include:
- Faster merchant activation.
- Simplified payment setup.
- Centralised compliance management.
- Streamlined sub-merchant onboarding processes.
- Unified payment operations and reporting.
For many platforms, the ability to efficiently onboard and manage sub-merchants is a key part of their growth strategy.
Managing sub-merchants at scale
As the number of sub-merchants grows, platforms often need visibility across onboarding, payment processing, settlements, providers, and operational workflows.
Payment orchestration solutions help payment businesses manage payment providers, routing, transaction flows, and reporting through a unified infrastructure layer. This can also help platforms support complex payment ecosystems and large-scale sub-merchant operations while maintaining visibility across their payment infrastructure.
