Internet merchant account for credit card processing (UK)
If your business is looking to accept payments online, you’ll need to have an online payment gateway and an internet merchant account.
Access PaySuite’s merchant services enable you to set up everything you need to process and settle electronic online payments securely, helping you to grow your business and give your customers access to convenient payment methods.

What is an internet merchant account (IMA)?
Unlike an account used for general banking transactions like deposits and withdrawals, or a standard merchant account used for taking card payments in person, an internet merchant account is specifically set up for processing and settling online payments. You’ll need different merchant accounts for face-to-face payments and phone payments.
The online merchant account acts as a holding space, temporarily storing funds while they undergo verification and authorisation checks, before then transferring them safely to your business bank account. Online payments carry unique risk profiles and compliance requirements, so an internet merchant account is essential to increase security for businesses and consumers.
While they’re often associated with Ecommerce, internet merchant accounts are also ideal for non-retail sectors like education, utilities, professional services and the public sector, where regular or recurring payments are common. A reliable online merchant service supports more flexible and secure billing, making them ideal for processing donations, utility bills and membership fees.

Why businesses need an internet merchant account
Without an internet merchant account, businesses can’t process electronic payments online. In the current digital-first world, businesses that aren’t able to process online payments will see an increase in customer dissatisfaction and may even lose them to competitors with more convenient payment options. While there are some services like PayPal and Stripe that provide online payment processing without the need for a separate merchant account, they tend to include high transaction fees and take longer for the funds to reach your account.
A secure online merchant account infrastructure also reduces the burden of compliance. This is especially important for growing businesses or those in highly regulated sectors. All internet merchant accounts must comply with Payment Card Industry Data Security Standards (PCI DSS). Features like tokenisation, fraud screening and authentication support such as 3D Secure help to protect your business from chargebacks and reassure your customers that their data is safe.
What’s the difference between an internet merchant account and online payment gateway?
It’s important to understand the differences between an internet merchant account and online payment gateway. Both are essential, providing different functions that enable your business to take payments online.
An online payment gateway is the tool that captures the card details. It acts as an intermediary between the customer and the business, encrypting payment information and performing authorisation checks before sending it to the business’ merchant account.
The merchant account is where the money goes before settlement. An internet merchant account is a special type of bank account that enables businesses to process online transactions. After receiving the information from the payment gateway, it processes the payment and moves the funds from the customer’s account to the business’ account.
What to look for in a merchant account provider
The right merchant services provider will offer more than just a way to take payments. It will support secure transactions, provide integration options with your existing systems, and ensure compliance with industry standards.
When choosing a provider, look for one that offers clear pricing, UK-based support, and flexibility around how you take payments. Not every online merchant account is built the same, so whether you need recurring payment options, B2B invoicing or multi-channel support, make sure your chosen provider is able to offer these.
If your business is expanding, choose a partner that offers more than just basic merchant accounts. Scalable merchant services let you grow without needing to switch providers, saving time, money and integration headaches in the future. Remember as well to check their security and compliance credentials to make sure they meet the requirements of your industry.
