How DEUNA Helps You Build a Customizable Payment Infrastructure to Boost Revenue

DEUNA

More than ever, consumers are choosing credit and debit cards to make their online purchases. But while checkout flows might feel seamless to shoppers, the reality behind the scenes is far from frictionless. In Mexico, 4 out of 10 online transactions are rejected, with only 62% of card payments being approved. That’s a massive gap—and a massive opportunity—for e-commerce businesses looking to grow.

So what’s going wrong? And more importantly, how can it be fixed? To answer that, let’s start by understanding the payment infrastructure powering every transaction.

How Do Card Processing Networks Actually Work?

Every time a customer enters their card details and clicks "Pay," a series of complex operations take place in seconds. These operations are handled by what’s known as card processing networks—the digital rails that connect issuing banks (the customer’s bank) and acquiring banks (the merchant’s bank).

Payment processors act as intermediaries, securely transmitting the transaction data and ensuring compliance with security protocols like PCI-DSS. The card networks—like Visa, Mastercard, and American Express—route the payment request and return the response. If approved, the funds move from the issuing bank to the acquiring bank, and finally to the merchant.

This invisible choreography must be seamless, but the reality is that many businesses only integrate with a single processor or bank, limiting their reach and performance.

Why Are So Many Online Card Payments Rejected?

Payment rejections happen for several reasons, many of which are outside the merchant’s direct control:

  • The issuing bank declines the transaction without a clear explanation
  • The purchase is flagged as suspicious or unusual
  • The user’s bank requires an extra step for approval, which isn’t completed
  • The customer abandons the transaction when their preferred payment method isn’t available

Each failed transaction represents more than lost revenue—it’s a broken experience that can prevent customers from returning.

Turning Complexity Into Conversion: DEUNA’s Orchestration Platform

This is where DEUNA comes in. Our payment orchestration platform simplifies the entire payment experience, allowing businesses to:

  • Integrate with multiple processors to increase approval chances
  • Automate dynamic routing, so declined transactions are retried instantly with alternative providers

With this orchestration layer, DEUNA enables merchants to recover failed payments, reduce chargebacks, and unlock new revenue streams—without adding technical complexity to their stack.

More importantly, this unified view gives them the clarity to act.
