Aggregated Card Acceptance ModelPayFac (Payment Facilitator)

This type of provider enables businesses to accept card payments quickly by signing them up as sub-merchants under a single master merchant account. Square, Stripe, and PayPal operate this way. Instead of applying for their own dedicated merchant account, sub-merchants onboard in minutes with no underwriting — but accept trade-offs in pricing, stability, and fund control.

For merchants who have outgrown flat-rate aggregators, Square alternatives built on real merchant accounts typically cut effective rates by 20–35%.

The model is purpose-built for speed. It works well for new or low-volume businesses that need to start accepting payments immediately. It becomes a liability for established businesses processing real volume, where the higher effective rates and risk of account holds cost more than the convenience is worth.

The structure works like this:

1. The provider holds a master merchant account with an acquiring bank
2. Businesses sign up as sub-merchants under that master account
3. The provider assumes liability for all sub-merchant transactions
4. In exchange, pricing, risk monitoring, and fund flow all sit with the provider
5. Sub-merchants accept cards immediately — but on the provider’s terms

Because the provider assumes underwriting risk for every sub-merchant, it protects itself through higher rates, reserve requirements, and the ability to hold or terminate accounts with little notice. The Federal Reserve’s interchange fee data shows the actual cost of card processing — the spread between that and what they charge is where their margin lives.

The model is a reasonable starting point. It stops making sense when processing volume grows large enough that the pricing premium outweighs the convenience. The general threshold is $10,000–$15,000 per month in card volume — above that, a dedicated merchant account with interchange-plus pricing typically saves $200–$500 per month or more depending on card mix.

Beyond pricing, dedicated merchant accounts offer individual underwriting — your business history, ticket sizes, and industry are known from day one. That means fewer surprises in the form of holds, reserves, or terminations. The CFPB’s guidance on payment services is clear that merchants have rights in these relationships — rights that are easier to exercise with a dedicated account than through their support line.

These providers conduct continuous risk monitoring across their entire sub-merchant portfolio. A spike in chargebacks, an unusual transaction pattern, or a policy change at the card network level can trigger an automated hold on your funds — sometimes without warning and without a clear path to resolution.

This is not unique to any one provider. Square, Stripe, and PayPal all have documented patterns of account holds and terminations. With a dedicated merchant account, holds are rare because your business is individually underwritten — surprises are surprises, not a feature of the model.
