According to The McKinsey 2022 Global Payments Report, the payments services industry is rapidly growing, uniting banks and technology providers to create similar seamless and convenient digital experiences. For instance, banks are optimizing their core systems and updating their payment infrastructure, largely in response to the continued rise of online payments, open-banking requirements, and cloud technology.

That’s why you have to choose what type of service you want to provide. Some payment processors serve only as gateways while others become acquirer banks and are partners with Visa or Mastercard.

For online payments, MPGS (Mastercard Payment Gateway Service) enables businesses to integrate payment processing into their websites and mobile applications.

Starting a payment processing business can be a complex process, but we will outline the steps to help you get started.

Building the payment processing software: start from scratch or get it off the shelf?

Building payment processing software from scratch can be a daunting task, as it requires a lot of your resources and may take a few years to complete. You will also need server infrastructure and robust security measures in place, and an expert development team capable of handling a complex fintech project (and plenty of time to implement your project from the ground up).

If you’re into cost- and time-efficiency, using a pre-developed white-label solution might be a more beneficial way to go. It enables you to brand and customize the ready software according to your product needs and seriously accelerate the release. In addition, working with a reliable vendor can help save your team resources, and costs, plus reduce CAPEX.

If you’d like to start earning revenue as soon as possible rather than spending months or years on a from-scratch project, let us guide you through the process of building a payment processing system using Platform as a foundation. With our payment acceptance solution, you can start growing your revenue by providing a complete stack of online and offline payment acceptance services for merchants faster.
