WooCommerce Payments in South Africa: Cards, Instant EFT, QR & Payment Links
January 16, 2026Failed payments, especially during the holiday season, are not just an inconvenience to customers and businesses. They also carry a significant cost to repair the damage. Prevention is therefore the best path forward for customer retention.
But in this rapidly changing landscape, it can be tricky to know where to focus your attention and which approach is best for each payment failure. From card and EFT payments to Buy-Now-Pay-Later and Scan-to-Pay, there are a range of reasons for payment failures unique to each channel.
This guide explains the most common failure types that happen in December and the solutions.
Don’t let the holiday rush slow your business down.
We’ll help you keep payments flowing smoothly—even during peak seasons.
Why online payments fail so often in December in South Africa
The holiday season in South Africa is a lively time often spent with family and friends. End-of-year bonuses fuel spending sprees around Black Friday, Cyber Monday, and Christmas.
But why do so many payments fail?
In short, it’s a mix of cart-filling peak periods and bank downtime that leads to more payment failures. Fraud spikes and viral sale waves only amplify the chaos, hitting SMEs hardest.
Why your online payment failed: Peak-season failure patterns
Payment failures aren't just declined cards. There are multiple possible issues blocking funds from reaching your account. Here are the main ones:
System overload
Christmas is a period of giving, so expect a high volume of transactions (especially after Black Friday). But now, with viral social media posts, your business can sometimes see sales blow up at any time of year. This influx of buyers can overwhelm payment gateway systems and sites, leading to timeouts, slow processing, or even crashes.
Legacy infrastructure can also cause bottlenecks in the process. Rigid central bank systems from decades ago can't handle real-time peaks, and siloed banks lack API integration, which can hinder smooth scaling.
Tips on how to improve this
- Get ahead of potential errors by using trusted partners like Netcash’s Payment Gateway
- Monitor your system performance to ensure it stays up to date and able to handle a surge in sales when the time comes.
3D Secure timeouts and One-Time PIN (OTP) issues
According to 2024 SABRIC stats, digital banking fraud remains a major problem, with over 65% of reported incidents. These figures are only increasing as AI tools become more widespread. That is why security protocols like 3D Secure and OTPs are so important.
With this, customers have between a few seconds and several minutes to approve or decline payments. But, sometimes this system works a little too well and times them out too fast, resulting in payment failures.
Tips on how to improve this
- Make sure you are providing clear communication to your customers about the 3D Secure process.
- Optimise your systems for mobile so they work fluidly across all devices.
- Work alongside payment providers to maintain support and offer insights during the process.
Limited bank windows
Many banks do not process payments over weekends and public holidays. And, unfortunately, South Africa has three public holidays in one month, which could cause payment delays or failures.
Typically, payments to the same bank provider are processed the same day, but transfers to another bank require a little patience and can take up to 3 business days to reflect.
Tips on how to improve this
- Ask customers to provide proof of payment as soon as they make a purchase to avoid further delays.
- Communicate to customers about possible delays or bank cut-off times that may affect payment delays.
Fraud attempts
Sometimes payments fail because of suspicious activity. BNPL fraud is becoming a growing issue for businesses, with estimates reaching $4.95 billion in 2025. But that’s not the only way people are trying to commit fraud.
That is why businesses should stay informed about payment fraud trends and how to protect their assets.
Tips on how to improve this
- The best way to prevent fraud attempts is to improve your site's security, from strong passwords to multi-factor authentication (MFA) for your employees and customers.
- Use tokenisation to replace sensitive data with a unique, unexploitable token.
Cart abandonment
We’ve done the math and seen that cart abandonment rates reach up to 75% in South Africa. During one of the most profitable times of the year, that could translate to a loss of millions of rands for your business.
There are several reasons for this, including high shipping costs, a poor user experience, and a lack of preferred payment methods.
Tips on how to improve this
- Find out where the blockage is in your customer journey and why. Typically, the most common pain points are inconvenient payment methods and slow delivery.
- Offer live chat support through AI bots or a team of people to answer any concerns or questions customers may have about making purchases.
- Use retargeting ads for the products in your customers’ carts on other websites to serve as a reminder.
Customer-driven errors and soft declines
Sometimes payment errors are not due to system failures but to customer errors. Things like insufficient funds, outdated cards, or accidentally entering incorrect data when making payments are all it takes. Luckily, these are easy and fast fixes.
Sometimes, banks may also issue a soft decline if a customer has reached their daily spending limit or if the payments are suspected of being fraudulent. In this case, the client would need to contact their bank to resolve the payment failure.
Tips on how to improve this
- Implement real-time validation on the payment page to highlight which fields contain incorrect details (e.g., an incorrect name, too few digits in the bank account number field, etc.).
- Send a reminder that you will hold their cart and that they can resume payment once the issue with their bank is resolved.
- Offer alternative payment methods and easy access to them if the primary card fails, so you don't lose the sale.
