The 84% problem: how payment reliability can be a growth lever for e-commerce businesses
Cart abandonment in South Africa reached 84% in 2025, and most of that loss traces back to one cause: payment failure. This article breaks down what the Stitch 2026 Consumer Payments Report shows about why checkouts fail, the specific signals that make consumers walk away, and a practical framework for auditing your own payment reliability before it costs you further.
South Africa's cart abandonment rate reached 84% in 2025, according to ECDB data cited in the Stitch 2026 Consumer Payments Report. For every 100 shoppers who add an item to a cart, only 16 complete the purchase. Critically, 62% of consumers who experienced a payment failure did not return to complete the transaction.
A Mastercard study found that declined card transactions are the single biggest cause of cart abandonment, accounting for approximately 52.2% of lost online sales. Payment reliability therefore is much more than a backend infrastructure concern.
Most enterprise teams already treat checkout optimisation as a priority, but the investment case tends to focus on the wrong end of the journey, including things like button placement, form fields and page load speed. Those improvements matter, but if a customer reaches checkout and the payment itself fails, no amount of interface polish recovers that sale.
What the data shows about failed payments
Stitch surveyed 3,000 South African consumers for the 2026 Consumer Payments Report and ran qualitative interviews to understand the real drivers impacting checkout abandonment.
When a payment fails, the immediate loss is the incomplete transaction. Longer term, a customer who hits a failure forms a broken mental model of the platform itself, not of the bank or network sitting behind it. That association impacts trust and is a large part of why 62% never come back.
Trust dynamics specific to South African consumers compound this further. Our research found that 45% of consumers would not feel safe paying online if they did not recognise the payment provider. A failed payment, particularly one that surfaces a confusing error message or an unexpected redirect, does more than lose a sale. It erodes the trust that future marketing spend is trying to build in the first place.
The specific red flags that kill transactions
Consumer research shows how checkout experiences can go wrong, and South African consumers have developed fairly precise mental models for detecting payment risk. When those signals fire, they disengage almost immediately.
The red flags that consistently break confidence at checkout:
- Unexpected pop-ups or redirects, cited by 57% of consumers as a fraud signal
- Unfamiliar payment providers, with 45% of consumers unwilling to pay if they do not recognise the provider
- Repeated data entry across sessions, where consumers expect their details to be remembered
- No visible two-factor authentication or biometric verification, which 59% treat as a safety signal, making its absence a negative cue
- Unclear refund processes, which weigh on first-purchase decisions even before a refund is ever needed
A consumer who encounters two or three of these signals at once is unlikely to complete the transaction, and reasonably likely to mention the experience to someone else. Word of mouth runs in both directions: a smooth checkout creates an advocate, and a broken one creates a detractor.
Why first-attempt success rate is the metric that matters most
Most payments reporting focuses on overall success rate, the proportion of transactions that eventually complete, sometimes after several retries. That number is useful for system health, but it hides the conversion picture. What matters for revenue is first-attempt success rate, because consumers who fail on the first try are disproportionately likely to abandon rather than retry.
That means the gap between a checkout with a 78% first-attempt success rate and one at 90% is not a 12-percentage-point difference in conversion. Once the customers who leave and never return are accounted for, the real gap is larger.
Stitch client data supports this directly. Businesses that switched to the Stitch payment gateway saw an average conversion improvement of 10% or more on a like-for-like basis against their previous provider. Apple Pay transactions processed through Stitch achieve a conversion rate consistently above 90%, with 50% of transactions completing in under three seconds, against roughly 80% success rates for card-based checkout. This leads to more consistent repeat customers as well as further trust built with the site or platform where they’re looking to pay.
A practical framework for auditing your checkout experience
Teams looking to assess where they stand can work through a structured audit across three areas: payment method coverage, checkout flow design and failure recovery logic.
- Payment method coverage. The 2026 Stitch report found that 93.3% of South African consumers tried a new payment method in the past 12 months. One-click wallets, including Apple Pay, Google Pay and Samsung Pay, led adoption at 57.5%, followed by Buy Now Pay Later at 38.9% and bank-specific apps at 38.6%. Capitec Pay alone has grown to 24.6% preference for online purchases. A checkout that does not offer these methods is losing customers at the method-selection step, before a payment ever attempts to process.
- Checkout flow design. Review the flow against the specific red flags consumers cite: unexpected redirects, unfamiliar provider branding, repeated data entry and the absence of visible security signals. Each has a direct fix. Redirects can be removed or made visually seamless. Branding can be whitelabelled so the merchant, not the payment provider, stays visible. Saved card details and biometric authentication cut re-entry friction. Two-factor authentication can be built into the flow as a visible feature rather than triggered only when risk is flagged.
- Failure recovery logic. When a payment fails, the platform should surface a clear explanation, offer an alternative method immediately and let the customer retry without re-entering every field. These recovery mechanics can meaningfully reduce the share of failures that turn into permanent abandonments. A decline does not need to be a lost sale.
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.
The investment case, in plain terms
A platform processing R100 million in online transactions a year with an 80% first-attempt success rate stands to gain materially from a 10-percentage-point improvement. Add the compounding effect of not permanently losing 62% of customers who hit a failed payment, and the case for treating payment reliability as a strategic investment rather than a line item becomes straightforward.
FAQs
What is South Africa's cart abandonment rate?
South Africa's cart abandonment rate reached 84% in 2025, according to ECDB data cited in Stitch's 2026 Consumer Payments Report, meaning only 16 in every 100 shoppers who add an item to a cart complete the purchase.
What causes most payment failures at checkout?
Declined card transactions are the largest single driver, accounting for approximately 52.2% of lost online sales, according to a Mastercard study. Beyond that, consumer research points to unexpected redirects, unfamiliar payment providers, repeated data entry and a lack of visible security signals as the most common triggers for abandonment.
How does Apple Pay compare with card payments for conversion?
Card-based checkout typically converts around 80% of attempts. Apple Pay transactions processed through Stitch convert at a rate consistently above 90%, with half of transactions completing in under three seconds.
What can merchants do to reduce payment-related cart abandonment?
The highest-impact actions are expanding payment method coverage to include one-click wallets, Capitec Pay and other bank-native methods, removing unnecessary checkout redirects, adding visible two-factor authentication and building failure recovery flows that offer alternatives instead of dead ends. Implementing a payments provider that enables the above while also offering built-in redundancies is the most reliable way to increase payments conversion.
