Do you want to develop your own payment gateway and become a payment service provider? Or maybe you have an innovative payment model (such as one based on QR code payments), and none of the available payment gateways meets your requirements.
Developing a custom payment gateway is the logical solution in both cases, but it’s dangerous to embark on payment gateway development without knowing all the details that could make or break your project.
At Relevant, custom web development is just one of the things we do well. With over ten years of experience under our belt and a team of professional app developers for hire, we know all the ins, outs, and “throughs” of payment gateway software development. Our developers are ready to build a custom solution for your company’s needs.
In this article, we’ll run you through all you need to know on the topic—from must-have features through legislation and security to the costs to expect if you decide to outsource your payment processing software development.

Before answering this, let’s clarify what we’re dealing with. What is a payment gateway?
From a business standpoint, a payment gateway is an intermediary between a customer (and an issuing bank acting on their behalf) and a merchant (and the acquiring bank acting on their behalf). A gateway enables secure online payment from one bank account to another. Two important aspects of payment gateway operations are fraud prevention and ensuring PCI DSS compliance. We will cover these in more detail below.
From a technical standpoint, a payment gateway is a system that accepts a customer’s billing details, encrypts them in a format understandable by a payment processor, and carries them across the payment network. It also sends notifications about approved or declined payments to the merchant’s web or mobile app.
There are two reasons you might want to create a custom payment gateway:
Either way, you’ll have to build and integrate a payment processing module that complies with regulations and meets your functional needs.
Let’s take a closer look at the features a payment gateway should provide.
Building a custom payment gateway can be a complex task, as you need to strike a delicate balance between your company’s requirements, the available tech capabilities, and security and legal compliance.
Determining the full list of features to implement will require conducting research and consulting with your chosen development team. To get you started, here’s a list of common features you’ll need in order to interact with payment systems and meet security requirements.
This is just the tip of the iceberg, as your full feature list will depend on your project specifics. Still, these are the must-have features of an efficient payment solution.
As you can see, cybersecurity and regulatory compliance are important requirements for payment gateways, so that’s where we’ll head next.
Secure payment gateways win consumer trust and help protect merchants from fraudulent chargebacks. Here’s a list of the cybersecurity standards and regulations your payment gateway solution will need to comply with in order to be registered.
Every business that has access to the cardholder information of its clients must meet the requirements of the Payment Card Industry Data Security Standard (PCI DSS). Failing to comply with PCI DSS opens the way to insecure transactions, a high risk of fraudulent chargebacks, increased payment processing fees, and even closure of the merchant’s account. You should also check the legal requirements of the countries you’ll be accepting transactions from, though PCI compliance is mandatory.
There are four PCI DSS compliance levels. The levels that you need to meet depend on how you handle your transactions.
To fully comply with PCI DSS requirements, you’ll also need to consider the cybersecurity standards and processes listed below.

EMV stands for EuroPay, Mastercard, and Visa and is a global standard for credit card transactions. It uses chip technology to prevent card-present fraud by exchanging dozens of different pieces of data between the card and the POS terminal.
EMV 3-D Secure means “three-domain” secure, so each transaction is secured by three domains: the card issuer’s domain, the payment acquirer’s domain, and the interoperability domain—the infrastructure used to deliver the payment data. Protected by SSL (TLS) communication and XML messaging, EMV 3-D Secure enables liability shift for chargebacks, meaning that when a fraudulent chargeback occurs, liability shifts from the merchant to the card issuer.
As mentioned above, replacing sensitive credit card details with tokens is a best practice for keeping potential attack scope minimal and protecting a customer’s payment data.
Peer-to-peer encryption (P2PE) allows organizations to build secure communication channels between particular devices to avoid transmitting secure data over an open network. This is yet another best practice recommendation to decrease the potential attack scope.
Now that we’ve covered security and compliance, it’s time to take a closer look at how to develop a payment gateway and integrate it with your systems.
There are three ways to get a payment gateway: by buying an off-the-shelf product, by developing it yourself, or by outsourcing the task to a reliable payment gateway software development company.
Relevant has extensive expertise in mobile and web development of payment gateways. Our payment solution development services include:
If you’re considering the outsourcing route, the budget is obviously a big factor. How much does payment gateway development cost, and which factors affect it?
Let’s set you straight.
The total cost of a solution depends on the number of features you need to implement and the complexity of integration with the rest of the systems you use. That said, manpower will be a large part of your project.
The cost of talent varies widely according to your outsourcing country. If you decide to hire a software development team in Ukraine (one of the best software outsourcing locations), these are the hourly rates you can expect in 2021:
These are ballpark rates: the final cost of developers will depend on things such as the technical seniority of the talent you hire, the technology stack you choose to build the product, and your project engagement model. For example, Relevant provides professional payment gateway developers that can build an end-to-end solution for your business or just be a temporary reinforcement of your capacities.
For a payment gateway development project, you’ll generally need the following roles at each project stage:
If you also need post-launch support or help with platform management, Relevant can help.
If you decide to develop your own payment gateway, your main challenges are:
Unsurprisingly, mistakes at any stage cost. To guarantee the best outcome, you need access to people who know how to develop a payment gateway system from scratch. At Relevant, we can provide web and mobile app development services to help you achieve this goal.
