Merchant Account vs Payment Gateway – What Are the Differences?

If you currently run or are thinking of starting an online business, understanding the roles of the payment gateway vs merchant account in the payment process will help you select the right processing partner.

A payment gateway and merchant account are both necessary for accepting credit or debit card payments, but they’re not the same thing. A payment gateway accepts customers’ payment information and routes this information through the payment network, while the merchant account is where the funds from card payments are held until they are released into the merchant’s business bank account.

What Is a Payment Gateway?

The payment gateway is the interface used by the consumer to enter their card details, whether you accept debit or credit card payments online or in a brick-and-mortar store. On a website, this is facilitated via the checkout page. In a store, this is achieved via the point-of-sale (POS) terminal.

1. To initiate the payment process, the customer enters their payment information into the payment gateway (the checkout page or POS terminal) and presses or clicks “OK.”
2. The payment gateway encrypts the customer’s account information and sends it to the merchant account provider. From there, it passes to the card network and finally to the customer’s bank (the issuing bank).
3. After fraud checks, authorisation, and authentication are complete at each stage, the issuing bank sends back a response (either approved or declined) to the payment gateway. This is displayed to the customer.
4. If the transaction is approved, the funds are received in the merchant account and held for a specified period. Funds are often held for 24 to 48 hours.
5. The funds are deposited into the merchant’s business bank account at the end of the holding period.

Gateways today go beyond debit and credit card payments. They also support local payment methods, mobile payments, Buy Now Pay Later (BNPL), QR payments, and even bank transfers. They also support real-time analytics and security features, including tokenisation and 3D Secure 2. Learn more in our guide to payment gateways.

What Is a Merchant Account?

The merchant account is the place where funds from in-store or online transactions are received and held until they are released into the merchant’s business account. Merchants have no control over the funds in their merchant accounts.

There are several reasons why a merchant account—separate from a business owner’s business bank account—is necessary:

• Card payments are typically processed in batches, not in real time. This means that card transactions can’t be settled straight away.
• If there is a chargeback or refund, the funds are paid out of the merchant account to ensure the customer gets their money back.
• Fraudulent transactions that are intercepted before the funds are released to the merchant can be reversed.

After any chargebacks are subtracted and the holding period is up, the funds are transferred into the merchant’s business account as a lump sum. From there, the merchant can access the funds and use them to make purchases, pay bills and wages, pay out shareholders, invest in stocks, make donations, or transfer money to other accounts.

Depending on the volume and nature of the transaction, many payment processors and merchant service providers today offer instant or same-day payouts. Rolling reserves with longer holding periods are often required in industries that are considered high-risk, such as gaming, travel, or crypto.

The Role of the Payment Processor

While it’s possible in theory, merchants don’t usually work directly with the merchant acquirer (acquiring bank) where their merchant account is held, or build their own payment gateway from scratch. They instead outsource their payment processing to a payment service provider that provides both a payment gateway and a merchant account.

Depending on the size of the business, a business owner has two main options when it comes to payment gateway providers:

Aggregate Merchant Account

Payment service providers that follow an aggregate merchant account model combine dozens, hundreds, or even thousands of merchants under a single umbrella. They process these sub-merchants’ payments through a single merchant account with an acquiring bank. Examples of merchant aggregators are PayPal, Square, and Stripe.

These platforms offer simplified onboarding, accepting accounts almost instantaneously. Fees tend to be higher, and control on the individual level is restricted.

Dedicated Merchant Account

A merchant account provider works with a network of acquiring banks and assigns a single merchant account to each of their clients. After a rigorous underwriting process, approved merchants are assigned a merchant identification number (MIN) and a dedicated merchant account.

Dedicated merchant accounts typically take longer to set up, but they offer more control of risk management, customised pricing, and overall flexibility.

Dedicated Merchant Account vs Aggregated Merchant Account

For hobbyists and very small businesses, aggregated merchant accounts provide a quick and easy way to begin accepting payments with a minimum of documentation and no contracts or monthly fees. However, as the payment processor needs to buffer itself against the combined risk of its sub-merchants, processing fees tend to be higher.

In contrast, dedicated merchant accounts offer more customised fee structures for registered businesses with a regular turnover. This potentially reduces the cost of accepting credit card payments significantly.

Merchant account providers also offer a vast array of merchant services that aren’t available with most aggregate payment accounts, such as monthly merchant statements, adjustable fraud scrub, chargeback mitigation, reports and analytics, recurring billing, and more.

Bigger merchants also use payment orchestration platforms connecting multiple acquirers and gateways. This automatically pushes transactions through the provider at the lowest costs with the best approval rates.

Emerging Trends in Payment Processing

Companies need to stay aware of trends in order to keep their businesses competitive and provide the best possible customer experience. These are the trends that are shaping payment gateways and merchant accounts today:

• AI-driven fraud prevention and smart routing: AI is increasingly being used by payment gateways to identify suspicious transactions and optimise routing.
• Support for alternative and local payment methods: Customers are increasingly using local and alternative payment methods. Offering the choice of multiple payment methods allows for better conversion rates.
• Evolving security and compliance standards: Data security regulations are ever-evolving. Partnering with a payment provider that is compliant with PCI-DSS, tokenisation, and 3D Secure 2 requirements will ensure your business stays protected.
• Unified payment experiences: Modern gateways cater to customers’ needs, enabling rapid and contactless payments. Businesses can manage payments from different channels, and automatically sync data to accounting and CRM systems from one dashboard.
• Faster access to funds: Instantaneous and same-day transactions are becoming more common, helping companies improve cash flow.

Succeed With a Payment Gateway and Merchant Account

Now that you understand the difference between a payment gateway vs merchant account, you’re ready to start shopping around for a payment processor that offers the best of both in a package that suits your business model and processing needs.

Companies can also start off with all-in-one platforms that act as both the gateway and merchant account. These options simplify setup and compliance, allowing smaller businesses or companies with smaller budgets to accept payments quickly and efficiently.

As your company grows, or if you are a larger merchant, a more tailored setup with customisable gateway features and a dedicated merchant account may be more suitable. This system will provide you with more flexibility, enabling you to optimise costs, manage risks, and better adapt to your evolving needs.

The key is choosing a partner that aligns with your size, needs, region, and business goals. Compatibility is also essential. Many payment gateways limit the banks, payment methods, and merchant accounts they’ll work with. Some financial providers restrict entire industries.

Once you find your ideal processing partner, you will be able to accept payments with full peace of mind, knowing that both your money and your customers’ money are secure and that your business will continue to operate smoothly.
