With the rise of e-commerce, the payment gateway market is thriving and expected to reach $106.4 billion by 2030. However, did you know that nearly 70% of online shopping carts are abandoned before checkout? This translates to billions of dollars in lost revenue for e-commerce businesses every year. Reasons for this may include mandatory sign-ups, unsatisfactory payment methods, high commissions, complex checkout processes, or inadequate security.

One solution to increase the number of completed transactions is by integrating a user-friendly and dependable payment gateway. A smooth checkout experience can help improve conversion rates and customer satisfaction. Which ones are worth considering, though? Let’s compare top payment gateways to give some insights into which might be the best payment solution for your business.

What are payment gateways?

Payment gateways are secure services that act as middlemen, processing transactions between customers, businesses, and financial institutions. They enable businesses to accept credit and other payment methods securely and efficiently across websites, mobile apps, and even physical stores. Also, gateways offer data insights for smarter business decisions. There are various payment systems available that cater to different business needs, making it crucial to choose the right one for specific requirements.

Payment gateways handle different tasks e.g.:

  • Checking funds (authorization): Before finalizing a sale, the gateway verifies if a customer has enough funds to pay for an ordered item. It’s used for orders that might take some time to ship or manufacture.

  • Capturing funds: After confirming the order, the gateway collects the payment from the customer and sends it to the merchant’s account.

  • Regular payments (sale): This combines both checks: verifying funds and then collecting them right away. It’s a regular payment for immediate purchases.

  • Refunds: If a purchase needs to be canceled, the gateway returns the funds.

  • Cancellations before transfer (void): It’s similar to a refund but can be done if the funds haven’t been processed yet.


Main types of payment gateways

There are four main types of payment gateways. Each of them offers different levels of control and integration complexity.

Hosted payment gateway

In this case, customers are taken away from the merchant’s checkout page. When they click the gateway’s link, they’re redirected to the Payment Service Provider (PSP) page to enter their payment details. While offering a simple setup, hosted payment gateways provide fewer options for customizing the checkout experience. The most well-known examples include PayPal and Amazon Pay.

API-hosted payment gateway

This method provides greater control compared to hosted gateways. Here, customers enter their payment details directly on the merchant’s checkout page. Payments are processed using an API or HTTPS queries. With API-hosted payment gateways, businesses can create a tailored checkout process. But, it requires greater technical know-how for implementation. Stripe is an example of this type of gateway.

Self-hosted payment gateway

With this option, businesses have the highest level of control and customization. They can handle the entire payment process on their own server. This gives brands maximum flexibility. However, it demands considerable technical expertise, security measures, and PCI compliance to ensure safe transactions.

Local bank integration payment gateway

It’s region-specific and directly links with a local bank’s system, skipping the usual payment gateway process. While efficient for busy businesses, it may lack global reach and functionality. Some examples include Klarna in Europe, UnionPay in China, and Rede in Brazil. These gateways also support multi-currency options, which helps businesses expand globally.

How do payment gateways work?

Payment gateways serve as secure intermediaries in online transactions. They manage the exchange of information and funds between merchants and customers. Here’s a simplified breakdown of this process:

  1. Customer checkout: At checkout, customers proceed to the payment page. Here, they enter their payment information, including the 16-digit card number, cardholder name, expiration date, and CVV number.
  2. Encryption and transmission: The payment gateway securely encrypts the customer’s card details and conducts a security check before forwarding them to the payment processor.
  3. Authorization request: The payment processor acts as a bridge between the gateway and the customer’s bank. It sends an authorization request to the issuing bank to verify if the customer has sufficient funds and if the card is valid.
  4. Authorization response: The issuing bank checks the customer’s account and sends an authorization response back to the processor. This response indicates whether the transaction is approved or declined.
  5. Transaction processing and fund transfer: If approved, the processor sends a signal to the gateway to capture the funds from the customer’s account. The funds are then transferred from the customer’s bank to a merchant account held by the payment processor.
  6. Confirmation and completion: Once the transfer is complete, the payment processor sends confirmation messages to both the merchant and the customer, finalizing the transaction. Typically, this entire procedure takes less than three seconds to complete.

Payment gateway integration: What to start with?

How can you integrate a payment gateway into the website or application? Well, there are a few steps to follow

First, do online payment providers comparison and choose a payment gateway that aligns with your business needs. Consider aspects like transaction fees, supported payment types, security measures, and compatibility with your e-commerce platform. 

Depending on the payment gateway, you might also need to set up a merchant account. However, some payment gateway providers offer both payment gateway and merchant account functionalities for simplified payment processing.

After signing up with the payment gateway, you’ll need API keys. These keys connect the website to the gateway securely, allowing communication between them. Then comes a decision point: you’ll need to choose between a hosted payment page or custom integration

Once you’ve made a decision, develop the technical connection between the website and the gateway. For a hosted page, you might simply embed a button provided by the gateway. For custom integration, you’ll need to develop code that securely transmits payment information to the gateway using API credentials.

Before you unleash the payment gateway on the world, thorough testing is essential. Use test data to simulate transactions and ensure everything works smoothly, including handling failed payments. Finally, with everything tested and ready, it’s time to launch the integration on the live website. 

Choosing a payment gateway provider

When doing payment processor comparison there are some important things to consider before choosing a provider. This involves prioritizing the business owner’s specific needs and understanding customers’ requirements. A well-chosen payment gateway can drive business growth by enhancing the customer experience, increasing conversion rates, and reducing cart abandonment.

Transaction fees are a major consideration, as they involve multiple financial entities. Like any service, a payment gateway comes with fees for using third-party tools to approve transactions. These fees vary based on factors like transaction amount, location, and product type. Payment solution providers, on the other hand, have their own terms and costs, covering setup, monthly gateway, merchant account setup, and transaction processing. Compare payment gateways and their fee structures to fit your budget and transaction volume.

  • Supported payment methods: Not all payment gateways support every payment method. Consider the methods most popular with your target audience. Will they need credit cards, debit cards, mobile wallets, or maybe buy-now-pay-later options? Ensure a chosen gateway offers the options your customers expect.
  • Security is paramount when handling sensitive financial information. Thus, look for a payment gateway that prioritizes security features like PCI compliance, data encryption, and fraud prevention tools. Don’t compromise on the safety of customers’ data.
  • Global reach: Do you plan to sell internationally? If so, choose a gateway that supports international currencies and payment methods relevant to target markets. This can be crucial for expanding customer base.
  • Ease of integration: Consider technical expertise. Some gateways offer user-friendly hosted payment pages that require minimal coding. For custom integrations, evaluate the complexity of the provider’s API and available resources for developers.
  • Customer support: Another important factor is the support team. Ensure that the payment gateway provider offers reliable customer assistance to handle any issues quickly, especially when dealing with sensitive data.
