If your business wants to take card payments, you need a merchant account. In simple terms, this special type of bank account helps businesses process card transactions safely. Whether you run an online shop or a physical store, the right merchant services can make payments easy and improve cash flow.
However, choosing the right merchant service provider can be confusing. With so many choices available, it’s important to compare merchant accounts to find one that suits your business. By understanding how payment processing services work, you can make a smart decision.
This guide explains everything you need to know about setting up a merchant account, how merchant payment processing works, and how to pick the right provider.
What is a Merchant Account?
A merchant account is a type of bank account that lets businesses accept card payments. Simply put, when a customer pays with a credit or debit card, the money first goes into the merchant account before moving to the main bank account.
For e-commerce businesses in particular, having an online merchant account is a must for e-commerce businesses. Without one, they cannot accept card payments from customers.
Additionally, merchant accounts are linked to a Merchant Category Code (MCC), which classifies businesses based on the type of goods or services they provide. MCCs impact processing fees and chargeback risks, so understanding the right MCC for your business is important.
A merchant account can help you grow your business by allowing you to reach customers in the regions and currencies that the merchant account provider supports. It will also have features to prevent fraud and chargebacks, which can cause financial problems.

How Merchant Payment Processing Works
Understanding how merchant payment processing works helps businesses handle transactions better. Here’s a simple breakdown:
- Customer makes a purchase – A customer enters their card details online or taps/swipes their card in-store.
- Authorisation – The merchant service provider sends the payment request to the customer’s bank.
- Approval or Decline – The bank checks the account and either approves or declines the payment.
- Settlement – If approved, the money goes into the merchant account before being transferred to the business bank account. It usually takes around 1–3 days.
To ensure smooth transactions and minimise delays in receiving funds, businesses should choose reliable credit card payment processing merchant solutions.
Since delays in merchant payment processing can affect cash flow, choosing a provider that offers fast payouts is essential. The right acquirer helps businesses maintain secure and uninterrupted transactions.
For businesses working with third-party sales agents or payment resellers, an Independent Sales Organization (ISO), such as CardCorp, offers flexible payment solutions. Many businesses partner with an ISO to access tailored merchant services, reduce processing costs, and receive better customer support.
Setting Up a Merchant Account
Setting up a merchant account correctly ensures hassle-free payments. A merchant service provider with options for different industries can help businesses find the best fit.
To make the right choice, businesses should compare merchant accounts to find the right balance between cost, speed, and security.
New to merchant services? Here’s how to get started:
- Pick a merchant service provider – Compare providers to find the best rates and services.
- Apply for a merchant account – Fill out an application with details like turnover, business type, and expected transactions.
- Connect payment processing services – Link your payment processing system to your website or card machine.
- Start accepting payments – Once approved, you can begin taking card payments from customers.
CardCorp helps businesses open the right merchant accounts by matching them with acquirers that align with their needs.
How to Compare Merchant Accounts
Not all merchant service providers offer the same service. That’s why it’s crucial to consider the following factors:
- Transaction fees – Check the cost per transaction and any monthly fees.
- Contract terms – Some providers have long-term contracts, look for flexible deals.
- Customer support – Good support is important if payment issues arise.
- Security features – Check if the provider offers other security features in addition to PCI DSS compliance.
- Payment options – The provider should support online and mobile payments.
Ensuring PCI Compliance is crucial for preventing fraud and maintaining secure transactions. Businesses must meet these security standards to avoid penalties and protect customer data. Learn more about PCI Compliance and how to stay compliant with industry regulations.
By comparing credit card payment processing merchant services, businesses can get the best deal.
Furthermore, businesses should check the payment processing technology a provider offers. Some merchant service providers have advanced payment systems with fraud protection and real-time reporting.
Common Merchant Account Problems and How to Avoid Them
Many businesses face problems with their merchant accounts. Here are some common issues and ways to avoid them:
- High fees – Some providers have hidden fees. Read the contract carefully.
- Fraud & chargebacks – Customers may dispute transactions, causing refunds and extra fees. Using fraud protection tools can help.
- Frozen or closed accounts – Some businesses face sudden account terminations because of high-risk transactions. Choosing a provider that understands your industry lowers this risk.
