South African e-commerce has crossed a symbolic threshold.

According to the Online Retail in South Africa 2026 study, produced by World Wide Worx in partnership with Mastercard, Peach Payments and Ask Afrika, online sales are expected to reach about R159 billion in 2026, representing estimated annual growth of 22.5%.

For the first full calendar year, online commerce is expected to account for roughly 10% of South African retail turnover. A decade ago, its share was below 1%.

These figures need to be read carefully. R159 billion and the 10% share are full-year 2026 estimates, based on sources including retailer financial disclosures, Statistics South Africa data and Ask Afrika consumer research covering 23,910 interviews. They are not yet final annual results. (Mastercard)

But the 10% milestone matters for another reason: once a market becomes large enough, its priorities change.

Early on, the challenge is making online shopping possible. Then the focus shifts to customer acquisition, broader choice and better fulfilment.

Once digital commerce becomes a material part of retail, a different question becomes more important: of the customers who want to buy, how many actually complete the purchase?

That is when every point of friction starts to carry a larger economic cost.

R29 billion of additional online sales in one year

The study estimates that South African online retail will add about R29 billion in turnover during 2026.

For perspective, the country’s entire online retail market was worth about R30.2 billion in 2020. In one year, the market is therefore expected to add almost the equivalent of its total size only six years ago. (Mastercard)

Growth is also being accompanied by stronger economics at several major retailers.

Takealot Group recorded its first full-year trading profit fifteen years after launch, reporting adjusted EBIT of R171 million. Pick n Pay’s online operation was profitable for a second consecutive year, while online turnover increased 32.7%.

Checkers Sixty60 sales reached R25.5 billion, up 34.5%, while TFG Africa’s online sales grew 49.2%. (Mastercard)

The signal is clear.

Online retail is no longer only a channel in which companies invest to capture growth. For the most advanced players, it is becoming a business expected to deliver profitability, loyalty and operational efficiency.

As the market matures, payments take on a different role

At small scale, a merchant may feel the payment problem is solved as soon as a customer can enter card details and receive confirmation.

At scale, that view is too narrow.

Between a customer deciding to buy and the order actually being confirmed, several points can destroy a sale:

  • a page that performs poorly on mobile;
  • delivery fees appearing too late;
  • mandatory account creation;
  • a poorly handled authentication redirect;
  • an interrupted session;
  • an unfamiliar payment method;
  • a declined transaction;
  • an incomplete return from authentication;
  • an authorised payment that is not correctly translated into a confirmed order.

Payment therefore becomes less of a standalone feature and more of a commercial journey component.

Peach Payments, one of the study partners, notes that 57.9% of online shoppers use a smartphone, compared with 26% using laptops. It argues that checkout should be tested in realistic conditions, including entry-level devices, constrained connectivity and interruptions during authentication. (Peach Payments)

A checkout that performs perfectly on a flagship phone over office Wi-Fi may not represent the customer’s real experience.

A payment decline is not automatically a bad outcome

Improving conversion does not mean a merchant should try to approve every transaction.

Some declines are necessary.

A transaction may be rejected because the card is blocked, funds are insufficient, a security control identifies elevated risk, or the issuer determines that the transaction should not be approved.

The real objective is to distinguish legitimate declines from avoidable lost sales.

That requires merchants to measure the payment journey step by step.

A simple funnel could track:

Visits → baskets → checkout starts → payment attempts → successful authentication → approved authorisations → confirmed orders.

This creates better diagnostic questions.

If customers disappear before a payment attempt is even made, the issuer is unlikely to be the problem.

If abandonment increases during authentication, the 3-D Secure experience, connectivity or return journey may need investigation.

If authorisation requests reach issuers but decline rates are unusually high, merchants can examine response codes, card type, transaction amount, market, channel, risk controls and transaction profiles.

And if a payment is approved but the order is not successfully completed, the problem sits downstream of authorisation.

Revenue alone hides all of these stages.

More payment methods do not automatically mean more conversion

South Africa also illustrates how the checkout is becoming more diverse.

Cards remain the foundation of online payments, but pay-by-bank services, instant electronic transfers, digital wallets and Buy Now Pay Later solutions now carry meaningful checkout volume. (Mastercard)

Peach Payments says 40.8% of retailers offer Instant EFT or PayShap and that digital wallets grew by more than 34% year on year. Yet its own interpretation of the data carries an important warning: adding every available payment logo is not necessarily the best strategy. (Peach Payments)

A checkout can become harder to understand when choices are added without a clear purpose.

The useful question is not simply:

“How many payment methods do we offer?”

It is:

“Which payment method actually improves completion for which customer, on which device and for which basket?”

A mature merchant should be able to compare at least:

  • payment-method selection rates;
  • completion rates;
  • authorisation rates where applicable;
  • abandonment;
  • processing time;
  • cost;
  • refunds and disputes;
  • repeat purchasing after a successful first transaction.

The best payment mix is not the one with the most logos.

It is the one that most effectively turns purchase intent into a successful transaction without compromising security or customer experience.

The opportunity also lies with customers who never complete the purchase

Another figure from the report deserves attention.

Peach Payments states that 79.1% of South African adults have internet access, while 34.2% shop online. The online-shopping figure is actually down from 36.6% the previous year. (Peach Payments)

That means much of the current revenue growth is being generated by consumers who already shop online and are buying more frequently or across more categories.

This creates two different growth challenges.

The first is winning new online shoppers.

The second is converting and retaining people who are already sufficiently interested to reach a site, basket or checkout.

As a market matures, the second challenge becomes increasingly economic.

A few additional percentage points of conversion can represent significant revenue at scale. Conversely, small frictions become expensive when they are repeated across millions of customer journeys.

What African e-commerce merchants can learn from South Africa

The lesson is not to copy South Africa’s model.

African markets have very different structures.

In several Francophone markets, mobile money plays a much larger role. Banking penetration, card usage, fulfilment models, social commerce, connectivity and trust in online shopping vary considerably from one country to another.

It would therefore be wrong to assume that the same payment mix or growth trajectory will apply everywhere.

What can be adopted immediately is the discipline of measurement.

An e-commerce merchant does not need to wait until online retail reaches 10% of national retail to understand:

  • basket-to-checkout conversion;
  • payment-attempt rates;
  • successful authentication rates;
  • authorisation rates;
  • the main decline reasons;
  • completion after authorisation;
  • performance by device and payment method;
  • the proportion of customers who return after their first purchase.

This visibility allows merchants to identify friction before scale turns it into an expensive problem.

At 10%, payment becomes a commercial performance variable

South Africa’s milestone is therefore more interesting than the R159 billion headline alone.

It shows what happens when a digital channel becomes important enough to be managed with the same rigour as the rest of retail operations.

At that point, saying “payments work” is no longer enough.

Merchants need to know how many customers reach payment, how many attempt to pay, how many authenticate successfully, how many are approved, how many complete their order and how many return.

That is how payment data becomes a commercial management tool.

For African e-commerce businesses, the lesson is straightforward: build that discipline before volume makes it unavoidable.

As digital commerce grows, payment gradually stops being a technical feature. It becomes a commercial performance variable.
