How to Become a Credit Card Processing Company

In the ever-evolving world of e-commerce, seizing control of your business operations is crucial. If you're an entrepreneur who craves autonomy, building your own payment gateway from scratch might be the way to go. This offers unparalleled customization, but it's vital to be realistic about the challenges involved. Let's embark on the journey of crafting your payment gateway, along with some essential tips. Before delving into this endeavor, let's understand the fundamental function of a payment gateway.

Crafting Your Payment Gateway: The Fundamentals

A payment gateway is the backbone of your online business. It empowers your website to collect payments via credit and debit cards seamlessly. Additionally, it serves as the intermediary between your customers, your business, and the payment processor. The payment gateway provides a secure platform for customers to input their payment details, encrypts this sensitive data, and forwards it to the payment processor or bank. When you decide to create your payment gateway, it's imperative to adhere to specific qualifications and ensure compliance with PCI requirements and the latest anti-fraud regulations.

Effective Approaches to Building a Payment Gateway

So, who should consider crafting their payment gateway? Typically, this endeavor appeals to larger businesses seeking independence from third-party providers or those experiencing rapid growth, requiring a tailored solution to meet their unique needs. The steps involved in creating a payment gateway vary depending on your business requirements, but most companies follow a process similar to the following:

Set Up Your Payment Gateway Infrastructure: To get started, you'll need a server to host your gateway. Whether you choose to host it on your own or through a third-party provider, you must consider maintenance and support for any associated data centers.

Select a Payment Processor & CRM System: Your payment gateway works in tandem with a processor to facilitate online transactions. This processor can be a financial institution, a credit card company, or an independent processor. You'll need to request the processor's API documentation and adhere to their implementation guidelines. Additionally, you'll have to develop an external API that facilitates the exchange of customer payment data. A robust Customer Relationship Management (CRM) system is essential for centralizing customer information, including their preferred payment methods and contact details.

Security Features and Necessary Certifications

When you embark on the journey to create your payment gateway, you assume responsibility for safeguarding cardholder data. To ensure data security, you must implement tools like tokenization, which replaces credit card numbers with anonymous tokens. Furthermore, compliance with Payment Card Industry Data Security Standard (PCI DSS) regulations is mandatory when handling credit card data. Apart from PCI compliance, you'll need to acquire a 3DS certificate from EMV (Euro-pay, Mastercard, Visa) to handle customer cards with chip technology.

Alternative Options for Building a Payment Gateway

If you're short on time, resources, or technical expertise, an alternative solution might be more suitable than building your payment gateway from scratch. Consider using a payment gateway provider like GoCardless, which offers a robust Direct Debit solution. This alternative eliminates the high per-transaction fees and failure rates associated with card payments. GoCardless also provides a convenient Instant Bank Pay service, ensuring instant payment confirmation and cost savings, being on average 54% cheaper than equivalent card transactions.

In the competitive realm of commerce, having a skilled merchant sales representative on your team can be a game-changer. These professionals possess the expertise to analyze market trends, devise effective sales strategies, and cultivate strong client relationships. With a merchant sales representative by your side, you're well-positioned for sustainable growth and success.


Creating your payment gateway can be a rewarding venture, offering complete control over your e-commerce operations. However, it comes with significant responsibilities, including data security and compliance. If you seek a quicker and cost-effective solution, partnering with a reputable payment gateway provider like GoCardless is a viable option. Their services can streamline your payment processing and help you save money in the competitive online marketplace.
