How to choose the best payment gateway - RFP guide

In today's global economy, companies of all sizes need to streamline their payment processes and diversify the payment methods they accept to improve the customer checkout experience. Central to this objective is understanding the roles of various parties within the digital transaction lifecycle, namely: customer, merchant or business, payment gateway, and payment processor.

The transaction process begins with the customer, who places an order and provides their payment details. These details are securely transmitted via a payment gateway to the payment processor, which plays an essential role in ensuring that sensitive data is securely handled and remains confidential. The payment processor then liaises with the card issuing bank while relying on card networks (e.g., MasterCard, Visa, American Express, etc.) to verify the payment details and confirm the transaction's authorization. Once authorized, the acquiring bank finalizes the transaction by settling the approved funds and transferring them from the card-issuing bank to the merchant's account.

Given the importance of these intricate steps to ensure payments are processed successfully, businesses must prioritize the selection of an efficient and reliable payment gateway. This decision is more than an operational matter; it directly shapes the customer's experience. A payment gateway simplifies the checkout process, providing a seamless and secure transaction environment through the deployment of robust encryption protocols and secure transmission of sensitive payment data. Furthermore, a flexible payment gateway gives merchants access to multiple payment methods and currencies. This capability enables businesses to cater to a global customer base and expand their market reach. Investing in the right payment gateway is strategically important to enhance customer satisfaction while driving sustainable business growth. 

When it comes to integrating a payment gateway, digital platforms often decide whether to develop their in-house payment infrastructure that connects directly to several payment processors and payment methods or partner with an established payment gateway provider. Developing an in-house payment infrastructure offers greater flexibility, but it demands significantly more resources, takes more time to launch, and also requires ongoing maintenance efforts. Alternatively, partnering with an existing payment gateway can save time and effort while still delivering essential features and capabilities. 

For merchants who opt to collaborate with a payment gateway, conducting an RFP (Request For Proposal) can help identify the most suitable partners that align with their specific needs. To create an effective RFP, it is essential to provide potential vendors with the necessary background information, including the following:

  • Reason(s) for conducting the RFP
  • Requested timeline for the vendor to follow
  • Evaluation criteria
  • Expected features and capabilities
  • Required integrations
