Why smart routing is essential to combat card payment failure in South Africa

Stitch platform data from early 2026 shows that, particularly in the e-commerce space, nearly one in four online card payment attempts in South Africa don't convert into a successful transaction. Importantly, these failures are not due to bank or provider issues, but rather issues on the customer side that require precise and timely communication in order to resolve.

Card as a payment method is not broken; however, the online card checkout flow stacks several friction points on top of each other, and each one is a chance for a customer to drop off or hit a failure point before paying. Many of these are within the control of the customer, but something they may not be aware of when attempting the payment.

When a card payment fails for any reason, it’s critical to prompt the customer to retry or make it easy for them to make the payment via another method. Otherwise, it’s more likely than not that the customer won’t come back to complete the payment. 

The key reasons card payments fail

Looking at payments data from the Stitch platform in  Q1 2026, we see a few primary reasons for card payment failure:

• Insufficient funds: approximately 37%
• Invalid card details: approximately 27%
• Exceeds withdrawal limit: approximately 15%
• Bank declined: approximately 10%
• 3D Secure abandoned: approximately 5%
• Other, including errors, fraud checks and timeouts: approximately 6%

Most of these causes have nothing to do with fraud. They are often the result of friction, such as a mistyped card number, an expired card or a withdrawal limit the customer forgot about. Every one of these represents a moment where the customer wanted to pay, but the checkout process got in the way.

What a failed payment costs e-commerce businesses

Cart abandonment in South African e-commerce reached as high as 84% in 2025, according to ECDB benchmarking data, meaning that for every 100 shoppers who add an item to a cart, only 16 complete the purchase. The consequences extend well past that single lost sale. Around 62% of consumers who experience a payment failure don't return to complete the transaction at all, and Mastercard research found that declined card transactions are the single biggest cause of cart abandonment, responsible for approximately 52.2% of lost online sales. For a high volume enterprise business, that's a direct and recurring hit to revenue.

Why bank-native payment methods succeed where cards struggle

Bank native methods such as PayShap and Pay by bank sidestep most of the friction points that cause cards to fail. There are no card details to mistype, no expiry dates to track, no 3D Secure step to abandon, and the customer authorises the payment directly through an interface they already trust. 

Our research shows that around 30% of card failures are caused by friction that bank native methods eliminate entirely, which translates into success rates approximately 20 percentage points higher than card. One consumer told us in our 2026 report: "Capitec Pay just makes it easier. I don't have to enter my card and I trust my bank."

What this means for e-commerce finance and product teams

Offering bank native methods like PayShap Request, Capitec Pay, Pay by bank and Variable Recurring Payments (VRP) alongside card gives customers a reliable fallback when a card fails, rather than losing the sale outright. Smart routing through a payment orchestration layer can also retry a failed transaction through an alternative path automatically, before the customer ever sees a decline. Failure rates also aren't evenly spread across the month: insufficient funds failures cluster heavily around specific days tied to South Africa's income cycle, a pattern worth planning around separately.

The Stitch platform offers built-in redundancies and automated failovers in the event a bank or 3DS provider is down. That means before any issues with the payment even reach a customer, we’re able to try another route. This has a significant impact on the overall conversion for first payment attempts.

Stitch data shows that merchants who switched to the Stitch payment gateway saw an average improvement of 10% or more in payments conversion on a like-for-like basis. For enterprise businesses, the starting point is understanding your current failure rate by method, by provider and by checkout step. Without that visibility, it is difficult to intervene effectively. Stitch provides merchants with client-specific monitoring and benchmarking data, including payment performance comparisons across industries, to give teams the insight they need to act.
