Choosing a Payment Gateway: 4 Major Factors

When choosing a payment gateway, there are four major factors you need to consider: transaction fees, card types, on-form payments, and recurring billing. These factors will vary by processor, so make sure you choose one that meets your needs and budget.

transaction fees

Transaction Fees

When you process a payment, some gateways will keep a small part of the charge for letting you use their app. You will either pay a flat fee per each transaction, an established percentage from each purchase or a combination of both charges.


credit card types

Card Types

It's important to know what types of credit or debit cards are accepted by your chosen payment gateway. Additionally, some processors require users to link their bank accounts rather than entering a card.


accept payments

On-Form Payments

If you use a pre-built form integrated with a payment gateway to collect your funds, pay attention to this factor. Some gateways will collect the payment right on the form, while others will direct users to another page to complete the purchase.


recurring billing

Recurring Billing

Recurring billing gives you the ability to set up a payment that reoccurs over a set period of time. If you need to bill your customers on a monthly basis without having to worry about performing this action manually, then you need a payment gateway that supports recurring billing. Examples of companies that might need this feature include subscription-based companies or nonprofits who have repeat donors.

Payment Gateway Comparison: Know Your Fees

So many payment gateways have different cost structures, but you will encounter a few standard charges during your research. Read on to learn about the different charges you must account for.

monthly fees

Monthly Fees

Some payment gateways will charge a subscription fee to let you collect money with their app. This monthly charge might vary based on the volume of payments being processed or the number of bank accounts where the payments are going.


setup fees

Setup Fees

Setup fees include any costs that might be associated with setting up your payment gateway account. You will only need to pay this fee once.

Merchant Account vs. Payment Gateway

Merchant accounts and payment gateways both provide ways to collect money from your customers, but they do it in very different ways. It's important to know the difference between the two as you assess the ways to manage your company's funds.

Payment Gateways

For every credit card transaction online and in-store, a service must communicate with the customer's credit card company to check for sufficient funds. In-store, typically, a POS (point of sale) machine performs this action. For online transactions, a payment gateway verifies the funds.

Merchant Accounts

A merchant account is a lot like a bank account, but its purpose is to collect funds from credit card payments until they are transferred to a normal business bank account.
