Payment Aggregator

A company that processes payments for multiple merchants under a single merchant account.

What is Payment Aggregator?

A payment aggregator (similar to PayFac) is a company that enables multiple merchants to process payments under a single master merchant account. Instead of each merchant obtaining their own account, they become sub-merchants under the aggregator. Companies like PayPal and Square pioneered this model. Aggregators handle underwriting, compliance, and settlement, enabling fast merchant onboarding but with less individual customization than direct merchant accounts.

Why It Matters

Aggregators democratized payment acceptance for small businesses. Understanding this model helps you evaluate whether aggregator simplicity outweighs the control and cost benefits of a direct merchant account. As you grow, understanding when to graduate from aggregation to direct accounts optimizes your payment costs.

Frequently Asked Questions

Often used interchangeably. Technically, PayFac is the registered entity type; aggregation describes the business model. Both process multiple merchants under one master account.

Aggregators price for simplicity and risk. Their flat rates subsidize instant onboarding, minimal underwriting, and accepting higher-risk merchants. The simplicity premium covers these costs.

Consider moving to a direct account when processing $10K+ monthly. At higher volumes, interchange-plus pricing through traditional processing typically saves money.
