What is Payment Gateway?

A payment gateway is a software application that functions as a channel between an e-commerce vendor’s website and the bank that processes a buyer’s credit card payment. A payment gateway can also process payments using methods such as debit cards and eCheck (ACH) payments. The main work of the payment gateway is to securely transmit the buyer’s sensitive credit/debit card and bank account data to the issuing bank and other entities involved in the transaction. Start by checking our leader PayPal Payments Pro, and other recommended solutions in this category.

Payment gateways send transaction data to acquiring banks and get replies from issuing banks about whether a transaction is accepted or declined. In short, payment gateways assist in effective communication between banks.

This buyer’s guide helps you out by providing a list of features and factors you should consider to select a suitable payment gateway for your needs. 

Targeted Businesses

  • E-commerce stores use a payment gateway to receive payments from customers who buy their goods online.
  • Small and large businesses that have an online presence and perform sales on the internet use a gateway for secure payment services.
  • Individuals use payment gateways for online purchases and transactions.

What are Examples of Payment Gateway Software?

  • PayPal Payments: PayPal is a quick and secure way to send and receive money, make an online payment, and set up a merchant account. It also offers business solutions for users to get paid securely on their website, mobile apps, or directly through their email address.
  • Amazon Payments: A fast, easy, and safe way to accept payments online. Companies can enable Amazon customers to simply login and pay using their Amazon credentials.

Types of Payment Gateway Software

Hosted payment gateways

These take a customer off from your website’s checkout page. After a user clicks on the ‘pay now’ button on your website, they will be sent to the payment service provider page. Here the user needs to fill their payment details. After the payment, they will be redirected back to your website to complete the checkout process.

Pro / self hosted payment gateways

For this gateway, you need to ask the payment details from users at your own website. After getting the details, you need to send the gathered data to the payment gateway’s URL. Some gateways need the info in a specific format while others need a hash key or a specific security key.

API / non hosted payment gateways

This gateway allows customers to enter their information directly on the merchant’s checkout page and processes payments using their APIs or HTTPS queries.

Local bank integration

These are similar to hosted payment gateways. The user is redirected to the payment gateway’s website where they need to fill the payment and contact details. After making the payment they are redirected back to the e-commerce website and notification data is also sent with redirection.

Platform based payment gateway solutions

This type offers a platform to e-commerce merchants to sell goods directly from their server. Merchants need to create subscription or products in the provided platform and users are redirected via checkout button to this platform.

Key Features of Payment Gateway Software

International payments

Some payment gateways offer multi-currency and international payments as well as an interface supporting multiple languages. You need to check where there are added fees for international and multi-currency payments and whether you need to set up a merchant account in a particular country.


Data security is essential for safe online payments. Make sure the gateway is level 1 compliant with PCI DSS and offers security features such as tokenization. Most gateways also offer fraud protection tools to ensure safe transactions with new parties.

Customer support

Good quality payment gateways offer reliable support through multiple channels. Do some research and ensure you are able to easily access the support agents anytime. Find out if you need to pay extra for support. Read online reviews about the quality of support offered by various gateways.

Payment methods

Payment gateways usually accept MasterCard, Visa, American Express, and PayPal for online payments. For international payments, check whether the gateway accepts local credit cards beyond MasterCard, Visa, and Amex. Always make sure you check what the exact fees are. For example, you can examine our comparison of Stripe fees vs Paypal fees vs Adyen fees to get a better understanting of what’s the standard in the industry.

Benefits of Payment Gateway Software

You can use payment gateway software to do the following:

  • Accept online payments for your e-commerce business.
  • Accept multiple payment methods and currencies.
  • Process payments safely by ensuring the security of payment details.
  • Avoid unauthorized payments with fraud protection safeguards.
  • Quickly handle customer refunds and returns.

Latest Trends

Mobile apps are replacing countertop checkout

Consumers are using their mobile phones to access cloud apps to checkout inside the shop and to pay for things before they step inside the store. Savvy brands like Starbucks, Taco Bell, Domino’s Pizza, Target, and Kohl are utilizing this trend to offer mobile payment apps and have seen a boom in their sales.

Faster and safer payments  

Many countries have implemented systems to facilitate faster payments. Beyond speed, payment gateways and apps are becoming more efficient and flexible. They are ensuring their systems meet security, compliance, and risk management regulations for safe online transactions.

Contextualized commerce is driving payments innovation

Payments are enabling the different digital experiences consumers engage in every day. Consumers spend many hours on the internet every day for different tasks. Companies are tracking their online behavior and habits to influence and trigger purchases. They are payment-enabling impulse purchases in innovative ways.

Potential Issues

Chargebacks and fraud

Payment gateways need protection against data theft and fraudulent misuse to ensure secure transactions. They need to use fraud-monitoring tools like purchase tracking, validation services, and risk management to detect fraud before it happens. Chargebacks are expensive and can damage the reputation of a gateway. Therefore, they need to use effective customer service practices to reduce or eliminate chargebacks.

Technical integration

It can be difficult for some gateways to integrate with other platforms which can result in processing delays, expensive fees, and lost transactions. Payment gateways need to ensure smooth technical integration with other systems to offer easy and secure transactions.

International transactions

International payments can be slow, expensive, and inefficient. Payment systems need to tackle this challenge and ensure fast and secure cross-border transactions and payments by managing the costs and risk more effectively.
