What Is a Merchant Agreement?

A merchant agreement is a contract governing the relationship between a business and the merchant acquiring bank it partners with. This document details the full range of electronic payment services that the merchant acquiring bank agrees to provide.

In most cases, such banks are responsible for facilitating every aspect of the electronic transaction process. Merchant banks frequently also serve as credit card providers for both open loop and closed loop merchant cards.

Key Takeaways

A merchant agreement is a contract establishing the parameters of the relationship between a merchant acquiring bank and the business it serves.
Although merchant banks chiefly facilitate electronic transaction processing, some also furnish credit cards.
The fees merchants pay merchant acquiring banks largely depend on the number of transactions conducted.

Acquiring Bank Relationships

Acquiring bank relationships make it possible for merchants to conduct sales of goods and services using electronic payment transaction methods. This partnership entails obtaining information from the merchant’s payment gateway technology, communicating with card issuers through the acquirer’s network, receiving authorization, and settling the transaction in the merchant’s account.

The fees merchants pay for electronic payment processing services vary based on online and brick-and-mortar transactions. Merchants are generally required to pay comprehensive fees to the acquirer for each electronic transaction, which covers both the acquirer’s fees and the processor's fees. Acquirers typically also charge a monthly fee for the settlement and bank account services they provide for merchants.

In cases wherein merchants disallow electronic payments and only accept cash, they will generally set up a standard bank account, that has its own set of requirements and contractual provisions.

While merchant agreements typically apply to vendors of goods or services, they can also touch upon foundations and charitable institutions.
