What is a Aggregated vs. Dedicated Merchant Account?

Payment processing is done through a single payment processing account for a dedicated merchant, whereas an aggregated account is a master account that many businesses can share under. Broadly speaking, a business can either be a merchant and open its own account as a single entity, or be a seller or one of multiple sellers who share another facilitator’s merchant account, also known as a payment facilitator.

The reason why the distinction is made is that it has a direct bearing on who you do your paperwork with, i.e., your service provider; what control you have over the terms of the account; how you get your money through; and, most importantly, what kind of responsibilities each party (you and yours or your service provider and their bank) have towards each other.

A dedicated merchant account is one that a specific company sets up with an acquiring bank or payment processor by signing an agreement directly with them. The company then undergoes its own underwriting, gets its own unique merchant identification number (MID) tied specifically to its business entity.

This setup typically involves a longer approval process, since the acquirer evaluates:

• the business’s financial history, 
• industry-related factors, 
• and processing volume individually. 

In exchange, the merchant gets more control over:

• settlement timing, 
• dispute handling,
• and account terms. 

Dedicated accounts are common among established businesses with steady or high transaction volume.

An aggregated merchant account is created in collaboration with a payment facilitator, often called a PayFac; the merchant becomes a sub-merchant with the master merchant account. Instead of getting a new MID, the merchant uses the facilitator’s existing system. The facilitator has completed the authorization relationship with the acquiring bank, which affects the merchant’s requirement to engage in that process.

The main difference is who owns the MID, the contract between the merchant and the acquirer/facilitator, and the flow of funds.

Depending on how different companies operate, different roles are assigned to processing card payments, even though their functions can be very similar.
· A company with the rights and licenses to hold and operate such accounts, including managing relationships with card networks and settling funds, is a full acquirer.
· An ISO is a third-party agent that resells processing services on behalf of an acquiring bank; while some manage merchant risk, they typically route settlement funds through the acquirer rather than holding funds directly.
· On the other hand, a payment facilitator is a person a merchant uses to make card payments. The merchant (under the facilitator) also does most risk evaluation and underwriting before the bank does.

Merchants that can afford to carry the compliance work of the whole process themselves may choose a dedicated account; however, for merchants that are going to take longer to be able to do that because of the setup time, the benefit here is a more personalized and in-depth underwriting review. 

Merchants prioritizing swift market entry, or those with varying transaction volumes, might prefer the aggregated option due to its operational characteristics.
