Buy Now, Pay Later has gone from novelty to default expectation on South African checkouts in about four years. The local market is now worth somewhere around R15 billion a year in transaction value and growing at double digits annually, and the big retailers have piled in — Shoprite and Checkers launched a BNPL option through PayJustNow in early 2026. For an online store, the pitch is irresistible: offer it and you’ll convert more browsers, recover abandoned carts, and lift your average order value. A lot of that is true.

But the pitch hides the part that matters to you, the merchant: you pay for it, the fee is meaningfully higher than a normal card gateway, and the seven main providers actually run three completely different models — one of which isn’t really “buy now” at all. Pick the wrong one for your products and you’ll pay a premium for installs that don’t convert. Pick the right one and it genuinely pays for itself.

We integrate these on Shopify and WooCommerce stores every week. This is the honest merchant’s-eye view of the whole market in 2026, the trade-offs nobody mentions, and how to choose. If you want the deep-dive on one of the more misunderstood options, we’ve also written a full LayUp review separately.

How BNPL actually works (and who pays for it)

The mechanics are simple and the same across most providers. Your customer chooses the pay-later option at checkout and splits the cost into interest-free instalments. The BNPL provider pays you — usually in full, usually within a day or a few days — and then takes on the job (and the risk) of collecting the instalments from the customer. If the customer defaults, that’s the provider’s problem, not yours.

In exchange, the provider charges you a merchant fee on every BNPL sale. This is the bit that gets glossed over: that fee is typically several percent of the order — noticeably more than the 2–3.5% you’d pay a normal card gateway like PayFast or Yoco. Most providers don’t publish a fixed rate; they quote per merchant based on your volume and category. So the real question isn’t “should I offer BNPL” — it’s “does the conversion and basket-size lift more than cover the extra fee for my products?” For low-margin, low-value items, often it doesn’t. For considered, higher-value purchases, it usually does.

Before you sign anything, run the extra fee through your margins. Our Shopify Profit Margin Calculator shows what an extra few percent does to what you actually keep, and the Payment Gateway Comparator sets the baseline of what your normal card processing already costs.

The three models hiding under one label

This is the single most useful thing to understand, and almost no comparison article mentions it. “Pay later” in South Africa actually covers three fundamentally different products:

• 1. Credit-style BNPL (get the goods now, pay in instalments). The classic model. The customer receives the product immediately and pays it off over a few weeks or months, interest-free if they’re on time. PayJustNow, Payflex, MoreTyme and HappyPay all work this way. Maximum instant gratification, which is why it converts.
• 2. Card-linked instalments (use your existing credit card, no new credit). Float pioneered this in SA. It doesn’t issue new credit — it sits on top of the customer’s existing Visa or Mastercard credit limit and splits the purchase into interest-free monthly instalments. The customer gets the goods now and keeps their card rewards. Built for bigger-ticket buys.
• 3. Digital lay-by (pay first, get the goods after). LayUp’s model, and the odd one out. The customer pays off the purchase in interest-free instalments but only receives the product once it’s fully paid. No credit, no credit check, zero default risk for anyone. It’s the modern, automated version of the old shop lay-by.

Why does this matter? Because the model determines who it suits. A customer with no credit card and a tight budget can use LayUp but not Float. A customer who wants the item today wants a credit-style option, not lay-by. Mobicred, meanwhile, is a fourth thing entirely — an actual revolving credit account that charges interest — so we’ll treat it separately.

The providers, one by one

PayJustNow

The most widely recognised BNPL brand in South Africa, owned by Weaver Fintech (part of the HomeChoice group) since 2022. The core product is Pay in 3: the customer pays one-third at checkout and the remaining two thirds on their following two paydays, interest-free if paid on time. For online orders, you ship once the first instalment clears. There’s now also a Pay in 12 option for bigger purchases, which does carry interest. Huge consumer network, strong brand trust, instant refunds to the customer’s wallet, and easy Shopify/WooCommerce/Magento integration. The Shoprite and Checkers rollout in 2026 has only grown its reach. If you want the option your customers already know by name, this is it.

Payflex

The original SA pay-in-4. The customer pays 25% upfront and the remaining 75% in three instalments over six weeks, interest-free. Acquired by Australia’s Zip Co in 2021. It suits smaller, more impulsive baskets — fashion, beauty, accessories — where a six-week, four-payment structure feels light. Quick checkout, well-established plugins. A solid choice if your average order value is on the lower side and you want fast, frictionless splits.

Float

The most interesting of the bunch and the one most merchants overlook. Float is card-linked: it splits a purchase into up to 24 interest-free monthly instalments using the customer’s existing credit card limit. No new credit, no application, no credit check, and the customer still earns their card rewards. Because it targets the roughly 6.5 million South Africans who already hold credit cards, its average order value is around R10,000 — nearly ten times the typical BNPL basket — with electronics, furniture and appliances leading. If you sell big-ticket items, Float is often the highest-impact option you can add, and merchants report materially higher basket sizes. You choose your settlement terms and the number of instalments you offer.

MoreTyme

TymeBank’s BNPL product, riding on one of South Africa’s fastest-growing digital banks. It splits a purchase into interest-free instalments and plugs into the TymeBank ecosystem and its large customer base, including a strong footprint among customers the traditional banks underserve. Worth offering if you want reach into TymeBank’s audience; availability and integration depend on your payment setup.

HappyPay

A growing BNPL option whose standout feature for merchants is how easy it is to switch on if you use Stitch: HappyPay can be enabled directly from a Stitch Express dashboard, removing most of the integration work. Interest-free instalments for the customer, simple activation for you. If you’re already in the Stitch ecosystem, it’s the lowest-effort BNPL to add.

Mobicred

The honest outlier. Mobicred is not interest-free BNPL — it’s a revolving credit facility backed by RCS, regulated under the National Credit Act, that customers use like a store credit card across many online retailers. They pay it off monthly with interest, like any credit account. It requires a proper credit application and affordability check. It’s a legitimate and useful option for customers who want an ongoing credit line, but don’t market it to your customers as “interest-free” — it isn’t. Treat it as a credit facility, not a 0% instalment plan.

LayUp

The digital lay-by option: interest-free instalments, no credit, no credit check, and the customer receives the goods only once they’ve paid in full. Because nobody is extending credit, there’s zero default risk and it reaches customers with no credit card at all — including cash payers, via a network of hundreds of thousands of physical payment points. Best for big-ticket items and budget-conscious or underbanked customers. We’ve written the full LayUp review here, including how it works for merchants and where it does and doesn’t fit.

The quick comparison

Which one should your store actually offer?

You don’t need all of them — a cluttered checkout with six pay-later logos hurts more than it helps. Match the option to what you sell and who buys from you:

• Lower-value, everyday or impulse products (under ~R1,500): PayJustNow or Payflex. The short, interest-free splits suit the basket size, and PayJustNow’s brand recognition reduces checkout hesitation.
• Big-ticket items (electronics, furniture, appliances, R5,000+): Float for your credit-card customers, and LayUp for those without credit. This pairing covers both ends of the market on exactly the products where a single payment causes the most cart abandonment.
• Customers who are budget-conscious or have no credit card: LayUp. It’s the only model that serves them, and it carries zero default risk for you.
• You’re already on Stitch: HappyPay is the lowest-effort add.
• You want maximum reach: PayJustNow has the broadest consumer network and now the big-retailer association too.

A sensible default for most SA stores is one credit-style option your customers recognise (usually PayJustNow), plus one that fits your price point — Float if you sell big-ticket, Payflex if you sell low-ticket, LayUp if you serve customers without cards. Two well-chosen options beat six.

The part nobody likes to mention: risk and regulation

BNPL is good for your conversion rate. It’s worth being clear-eyed about the rest. South African BNPL currently sits largely outside the National Credit Act, which is precisely why it can skip the affordability checks that normal credit requires — and why regulators are paying closer attention. Industry voices, including Float’s own founders, have flagged that interest-free BNPL doesn’t show up on credit records, which makes it easy for consumers to stack multiple plans across stores until small payments quietly add up. And while the instalments are interest-free, missed payments on credit-style BNPL can attract late fees that are steep relative to the purchase.

For you as a merchant this is mostly a reputational consideration: offer flexible payment, but don’t push customers toward debt they can’t manage. It’s also a reason the lay-by and card-linked models are interesting — LayUp extends no credit at all, and Float uses credit the customer already has rather than creating new debt. Expect the regulatory picture to tighten over the next year or two; pick providers who are transparent and well-backed.

Frequently asked questions

The bottom line

BNPL is no longer optional on a serious South African checkout, but “offer everything” is the wrong instinct. Understand the three models — credit-style, card-linked, and lay-by — match one or two to your price point and customers, and weigh the higher merchant fee against the lift it actually delivers for your products. Done deliberately, it’s one of the highest-impact additions you can make to a store. Done carelessly, it’s an expensive logo on your checkout.
