Here’s the reality of eCommerce in South Africa: if you sell online, customers need a secure way to pay. Having a website and an optimised shopping cart alone cannot move money from the customer’s bank account to your business. That’s where a payment gateway comes in.
Payment gateways connect the checkout experience to the payment infrastructure involved in authorising and processing a transaction.
In this guide, you’ll discover what payment gateways are and how they work. It also explains what to consider when choosing a gateway and how to set one up step by step.
What is a payment gateway in South Africa?
In plain English, a payment gateway is the digital equivalent of a card payment terminal. It is a secure tool that facilitates the transfer of payment information between an online checkout and the banks that authorise a transaction. It makes sure funds are processed quickly and safely.
A gateway does not simply move money from the customer’s account into the merchant’s account. It plays a role in securely forwarding payment information and facilitating authorisation, while other parties and processes can be involved in processing and settling the transaction.
The exact flow can vary depending on the payment method, provider, and integration. This is why choosing a gateway is more than just comparing transaction fees. The payment methods, security, integrations, settlement, reporting, and support can all affect how suitable the gateway is for your business, making it crucial to pick the right gateway for processing online payments.
How do payment gateways in South Africa work?
The online payment gateway workflow may seem to take only seconds from the customer’s perspective, but in reality, several processes and security checks happen in the background.
The payment journey step by step (how the money actually moves)
A typical card payment follows a process similar to this:
- Payment initiation: The customer selects a payment method (e.g., card, EFT, digital wallet, etc) at checkout, enters the required details, and confirms the purchase.
- Secure transmission of payment information: The gateway captures relevant payment data and uses security measures such as encryption, SSL/TLS, tokenisation, and authentication tools like 3D Secure to protect it during transmission through the payment infrastructure. The exact technology used here can vary between providers and payment options.
- Sending transaction for authorisation: The payment information is routed through the relevant processing and payment-network infrastructure to the customer’s issuing bank or financial institution, which verifies whether the transaction can be approved.
- Transaction approval or decline: The issuing bank returns a response indicating whether the payment can proceed (some banks and payment gateways require in-app confirmation from the buyer). The result is then passed back through the payment infrastructure to the gateway and merchant’s checkout, where the customer can see whether the payment was successful.
- Transaction settlement: If authorised, the transaction proceeds through the applicable clearing and settlement process. This is the stage at which the funds are transferred through the relevant financial institutions and ultimately made available to the merchant according to the provider’s settlement arrangements.
Note: The process above is a simplified example of a card transaction. Other payment solutions can follow different processes, so make sure to check your payment provider’s documentation rather than assuming every online payment moves through exactly the same sequence.
What happens when payment fails?
A payment gateway does not guarantee successful transactions. A declined or unsuccessful payment can have several possible causes. These include issues with the customer’s payment method, authentication, available funds, risk controls, configuration, or the payment system.
It’s important to make a clear distinction between a declined transaction and a technical or integration problem, because you may otherwise treat every failed payment as the same issue.
Set up automated triggers to alert customers when a payment fails, without using confusing banking terms. Provide alternative payment options via a secure link, offer a retry option, or encourage customers to contact their financial institution directly for bank-related issues.
Payment gateway vs payment processor vs acquirer
The terms payment gateway, payment processor, and acquirer are often used interchangeably, but they refer to different functions within the payment ecosystem. Understanding the difference can help your business evaluate payment providers without getting lost in technical terminology.
How they work together
For a typical online card payment, these functions can work together as part of a single transaction. The gateway handles the checkout connection, the processor facilitates the transaction through the relevant payment infrastructure, and the acquirer represents the merchant side of the payment arrangement.
However, these functions do not necessarily belong to three separate companies. A payment provider may offer several of these services as part of a single solution. The exact arrangement can therefore differ between providers and online payment solutions.

What should you look for in an online payment gateway?
Choosing an online payment gateway in South Africa should start with how your business operates and how your customers prefer to pay, not how much it costs. A gateway should fit your current setup while providing the payment options, security, and support you need as your business grows.
1. Payment methods
Not all customers like to pay the same way. A gateway can therefore be more useful when it supports a range of relevant payment methods rather than limiting customers to one option.
Netcash currently offers more than 20 payment solutions, including cards, Instant EFT, Capitec Pay, Bank EFT, Scan to Pay, Payflex and voucher and retail payment options. Merchants can select which available payment options they want to offer, subject to applicable requirements.
The right selection depends on your customers and business model, so avoid enabling every available option simply because it exists. Instead, choose those relevant to your target market.
2. eCommerce integrations
Your payment gateway should seamlessly work with the platform powering your online store.
For example, businesses using WooCommerce can integrate the Netcash Payment Gateway via the Pay Now service and the WooCommerce plugin. Netcash also offers a Shopify integration, but check current availability and setup requirements before implementation.
Businesses using custom-built websites may need a different integration approach, so check the provider’s current technical documentation or reach out to them before choosing a gateway.
3. Security and compliance
Check the provider’s security credentials and payment-security features before signing up.
Look for information about PCI DSS compliance, 3D Secure, encryption, fraud controls, and other safeguards. Also establish which security and compliance responsibilities remain with your business; while gateways do most of the heavy lifting, some features are still in your control.
Avoid relying solely on statements such as “secure” or “PCI compliant”. Look for specific, verifiable information about the provider’s security standards and the scope of its compliance.
4. Settlement and reconciliation
A gateway should make it practical for your business to understand which payments have been received, when funds are settled, and how transactions correspond with your financial records.
Good reporting and reconciliation become increasingly important as transaction volumes grow. They can help you identify discrepancies, track payments, and maintain accurate records.
Check exactly what reports, statements, and reconciliation tools the provider offers and whether they can integrate with your existing accounting processes.
5. Customer support
Payment problems can affect both your customers and your sales, so support should be part of your gateway evaluation, not an afterthought when something goes wrong.
Check which support channels are available, whether technical documentation is provided and what assistance is available during integration and troubleshooting. Avoid choosing a provider based solely on advertised support claims. Consider whether the available support aligns with your business’s technical expertise and requirements.
6. Scalability
Your payment requirements may change as your business grows. The gateway you choose should therefore be evaluated against both your current needs and the payment services you may need as your business grows.
Consider whether the solution can support increased transaction volumes, additional payment methods, subscriptions, payment requests, new sales channels, or eCommerce integrations where relevant. This does not mean you need every feature immediately.
Instead, choosing a gateway with relevant capabilities can reduce the need to change payment infrastructure as your requirements evolve.
How to get started with Netcash
If you have decided that a payment gateway fits your business, the next step is choosing a solution that works with your existing systems and customer payment preferences.
Netcash’s Payment Gateway allows South African businesses to accept multiple payment options through one centralised solution. The current offering includes card payments, Instant EFT, QR-based payments, BNPL options, vouchers, and other popular payment methods.
1. Decide on the payment methods you would like to accept
First, decide which payment methods you want to offer your customers. Consider how your customers prefer to pay, the types of transactions you process, and whether you need options such as cards, EFT, instant payments, QR payments or buy-now-pay-later solutions.
2. Connect your existing store
Netcash provides integration for several platforms including WooCommerce. Its WooCommerce setup requires an active Netcash account, Pay Now, and a service key, and it uses the Netcash Payment Gateway plugin. For Shopify, Netcash currently offers an integration that connects Shopify stores to its Payment Gateway. Sign up for the latest Netcash Shopify information for current availability and onboarding requirements before recommending it to merchants.

Managing payments across multiple systems can make reconciliation more difficult as your business grows. Through the Netcash Payment Gateway, payments can be received and settled into the merchant account, with multiple clients and platforms reconciled on a single statement.
This can give you a central point for reviewing payment activity. It’s still best to confirm which reporting and reconciliation features are included in their specific service arrangement.

Before implementing a gateway, make sure you understand the activation, integration and testing requirements for your chosen eCommerce platform.
Netcash provides setup and integration documentation for supported services, including WooCommerce. Businesses can also contact Netcash about their payment gateway requirements and account setup.

A payment gateway is more than a button that lets customers pay online. It sits between your checkout and the wider payment infrastructure, helping facilitate transactions while supporting the payment methods, security and integrations your business depends on.
When comparing gateways, look beyond the transaction fee. Consider the payment methods your customers need, security and compliance requirements, eCommerce integrations, settlement and reconciliation, customer support, and whether the solution can accommodate your future needs.
