Understanding every part of the payment flow may seem difficult as it consists of multiple steps and parties. We’ve made it easy for you by narrowing it down and focusing on the first step of the flow: the payment gateway.
If you’re wondering what a payment gateway is, you’ve come to the right place. This article will give you a better understanding of what a payment gateway is and what to consider when choosing one for your business.
What is a payment gateway?
A payment gateway is a service that helps businesses initiate and accept payments. It’s typically a web server to which a business’s website or POS system is connected, providing different channels to accept payments, such as online, in-app, or in-person.
You can either choose a payment gateway that is provided by a bank or one from a provider that can connect to one or more payment processors.
Types of payment gateway
Online payment gateways often offer services for both websites and apps. Although they have the same function (initiating payments), they can differ in the functionalities, features, and channels they support. It’s essential to choose one that works best for your business.
For example, subscription businesses often need a gateway that supports recurring payments. SaaS or marketplaces might require one that can offer embedded payments. Businesses in industries like airlines and gambling might need a high-risk payment gateway with a high-risk appetite.
Where the payment gateway sits in the transaction flow
Even though payments are completed in a matter of seconds, quite a few steps happen in the background. Since the payment gateway initiates the payment, it’s the first step of the transaction flow.
Below is the payment flow (in simple terms):
When a customer makes a purchase, the business sends the customer's payment information to the payment gateway.
The payment gateway shares it with the payment processor, which shares it with the card scheme.
The card scheme shares it with the issuer, which performs checks to determine if the transaction should be approved or declined.
The decision regarding the transaction flows through the card scheme, payment processor, and gateway to the business and customer.
Choosing the best payment gateway for your business
There are several factors to be aware of when choosing a payment gateway. Some may be more important to your business than others.
Different gateways have different pricing models. Saving costs is often a priority for businesses, which makes it important to choose a gateway with a pricing model that suits your business needs.
Some gateways charge a percentage-based fee, and some a fixed fee per transaction. If your transactions involve a high number, a fixed fee could be more cost-friendly.
When calculating the potential costs, it’s also important to remember that some gateways are for one-off costs like setup or integration fees. They might also offer services like 3D Secure, protection against payment fraud, or authorization optimization, which may affect the cost but add value to your business.
Security and compliance
Security and compliance are central to protecting your business and customers. The payment gateway should hold specific certificates and conform to measures to protect payment information. The ones you should expect are:
Payment Card Industry Data Security Standard (PCI): This is crucial for businesses that accept credit card payments. Businesses must adhere to 12 security standards when handling credit card data, including accepting, transmitting, processing, and storing it.
Payment Services Directive 3 (PSD3): The gateway needs to follow these new regulations on payment authentication if you accept payments in the European Union (EU). However, they haven’t been implemented yet, which means that Payment Services Directive 2 (PSD2) and Strong Customer Authentication (SCA) still apply.
General Data Protection Regulation (GDPR): This regulation ensures that personal data is only used for purposes for which the customer has consented. Businesses must follow the GDPR to accept payments in the EU.
There are a few things to keep in mind if you accept international payments. First, it's essential to ensure your gateway can accommodate this. You can accept international payments through cross-border transactions or local acquiring, which tends to offer higher authorization rates.
Another critical aspect of accepting international payments is offering your customers' preferred payment methods. That's why you need to make sure your gateway provides the payment methods you need. It could also be relevant to check if the gateway can accept foreign currencies and the associated fees for your international payments.
Different countries have different regulations. For instance, in Australia, there are specific rules on authentication and in Japan, new 3DS regulations will be implemented by 2025. Your payment gateway must comply with all the local regulations where you plan to accept payments.
Different gateways offer different levels of flexibility when it comes to integration options. You can either integrate with the gateway directly through one or multiple APIs, or with your ecommerce platforms through plugins, if the partnership exists.
