Insider Intelligence also expects revenue the online payments providers can collect as fees will increase from $82 billion in 2018 to $138 billion in 2024. In this article, we highlight the most common types of merchant service providers, and their functions and describe how to become one of them. 

What is a merchant services provider?

A merchant services provider is a financial software partner that allows the accepting and processing payments. It serves as a mediator between banks, customers, and merchants, providing debit and credit card transactions. 

The merchant services provider, or MSP, has various offerings for businesses, including digital payments, technology integrations for transaction tracking, POS services, CRMs, business data understanding, and collection of outstanding invoices. Understanding the features and capabilities of merchant services can help you develop a payment processing platform that is right for your business needs.

3 Types of merchant services providers 

Different providers offer different features so you can choose the best solution for your type of business. Most merchant services can be categorized into several types and differ from their competitors by certain functions. According to different functions, there are three of the most common types of services available through merchant providers:  merchant accounts, payment services, and payment gateway providers.  

Merchant account providers 

These entities are the most popular service providers. They offer a merchant account specifically designed for businesses to accept credit and debit card payments. Merchant account providers are extremely helpful for companies that make a large number of transactions with credit and debit cards. With this model, the processor (or the Bank) issues a Merchant ID, that is exclusive to your business and no one else.

Offering access to exclusive merchant accounts, they allow businesses to control payments and get benefits from quick access to funds and low transaction fees. 

They also can provide other services to enhance your business’s payment methods, including:

  • Credit card terminals
  • Mobile card readers
  • POS systems

Merchant accounts can also have the following fees: monthly minimum, billing, authorization, transaction, customer service, and maintenance.

Payment services providers 

While large companies have merchant account providers, there is an alternative for small businesses that do not need an additional account. Payment service providers (PSPs, third-party processors or aggregators) enable businesses to accept digital payments both offline and online, without having a dedicated merchant account.

For example, you do not need to have a unique merchant ID number, because your account is aggregated with other merchants. PSPs simplify payment processing for small business owners, despite having longer processing times and higher overall costs.

What is the difference between a merchant service provider and a payment service provider?

Despite the similar functions, there is a key difference between a merchant services provider and a payment services provider. Payment service providers consolidate multiple businesses under a single account, while merchant services providers establish a separate account and identification number for each business they serve.

The table below illustrates the difference between a merchant services provider and a payment services provider:

Characteristics  Merchant service provider  Payment service provider
Description  Merchant service providers offer an account specially designed for business to accept credit and debit card payments. Payment services providers offer your business the ability to accept credit card payments without a dedicated merchant account.
An approvement process Involves verification and compliance process that may take weeks. Typically instant approval.
Merchant account setup The underwriting process varies by the bank account provider and can have different requirements for opening an account. Payment services providers provide easier ways to set up. PSPs are free to sign up for and there is minimal documentation that is required to activate your account.
Pricing More complex fees including: flat-rate, interchange-plus and tiered pricing Fewer fees to worry about in general
Processing volume Negotiable limits on transaction size and processing volume. Can offer strict limits on transaction size and processing volume.

While PSPs consolidate a variety of different merchants under a single umbrella account, merchant services providers offer a dedicated account for accepting electronic payments. Each of these methods provides debit and credit card transactions but has specific functionality to meet your business needs.

Payment gateway providers 

A payment gateway provider is a kind of merchant service provider that authorizes the processing of card or direct payments. It serves as a mediator between the business and the customer, allowing businesses to accept online transactions through a secure network. 

Payment gateway providers can offer more than a simple function of enabling your business to process credit and debit card transactions over the Internet. They also provide a high level of security and fraud prevention so that both you and your customers can conduct online financial transactions seamlessly. 

Payment gateway providers offer the following features: fraud detection, 24/7 customer support, and international payment processing, recurring billing. It is also important to ensure that the payment gateway is Payment Card Industry (PCI)-compliant.

Merchant services products

The majority of merchant service providers offer a wide range of services and products for businesses to accept and process payments. Here are the most common categories of merchant services products:

Merchant accounts 

A merchant account is a type of bank account that is specially made for business purposes to accept and process electronic transactions by debit or credit cards from customers. This account serves as a temporary holder for card payments, acting as an agreement between the business (also known as an acceptor) and an acquiring bank.

The merchant account stores funds from processed transactions. Those funds are then transferred by your provider into a business account that you specify, such as a business checking account.

Credit card terminals 

Credit card terminals which are also called electronic data capture machines are digital products that allow customers to physically swipe, dip, or tap a credit card to make a payment. These machines connect to the merchant service provider and process and validate transactions. There are many different sizes and forms of credit card terminals: from simple magstripe swipers to handheld terminals.

Point-of-sale (POS) systems 

A point-of-sale or POS system usually consists of the software and hardware to accept payments. It also can manage a company’s daily operations and processes: processing sales, producing reports, monitoring inventory, managing staff, reconciling tips and commissions, accepting gift cards, and setting up loyalty programs.

Mobile payment systems 

With mobile payment systems, the smartphone or tablet can function as a credit card terminal. They consist of a mobile card reader that connects to your mobile device and an application to communicate with your provider’s processing network. These mobile payment systems provide online transactions in any place, where there is an internet connection. 

Payment gateway 

A payment gateway is a software that enables you to accept and process safe credit card payments online through your website or e-commerce store. In essence, the payment gateway replaces the credit card terminal. Customer credit card information is gathered and encrypted by a payment gateway for later processing.

Virtual terminals 

A virtual terminal is a software that enables businesses to accept payments made with a credit card, without the card having to be physically present. It is a program that transforms your computer into a credit card terminal. An optional USB-connected card reader can be used to swipe cards or manually input transactions. Businesses that accept orders over the phone or by mail and don’t have an e-commerce website are most likely to use virtual terminals.

How does a merchant services provider work?

  1. The customer tapes a card on the POS terminal or enters payment information online. 
  2. The merchant service provider sends payment information to the bank.
  3. The bank sends the transaction to your merchant service provider and the card company, like Visa or Mastercard. 
  4. The transaction information is sent to the customer’s bank to receive approval. 
  5. The customer’s bank either approves the transaction or declines the payment. 
  6. The card company sends the confirmation to the merchant’s bank.
