How to Develop a Payment Gateway – in 4 Stages

Online marketplaces are complex systems. This complexity is reflected in the Payment Gateway needed for such platforms.

As a marketplace owner, you always have the option to integrate payment systems, offered by external Payment Service Providers. Depending on your business strategy, that might suffice. But using an off-the-shelf PSP will also limit your opportunities. You can’t evolve your marketplace to your preferences if the PSP doesn’t move along with you:

  • You want to offer payment methods, according to customer demand? The PSP must support them.
  • You want to scale up your business and move to new markets? The PSP must be set up to handle higher transaction numbers and adapt quickly to local financial regulations.
  • You want to enable customers to pay via a prepaid e-money balance and securely store their payment instruments? The PSP must offer an electronic wallet.
  • And so on…

Thus, ambitious marketplace owners might decide to build a custom Payment Gateway and remain in control over payments. As the company behind CoreWallet, the flexible software foundation for payment and e-wallet applications, we are familiar with creating Payment Gateways. It’s important to approach the development process with a clear plan. To help you master the technical challenges, we have compiled the common stages of such a Payment Gateway project for you.
