TL;DR: Payflex is the simpler choice if you want a consistent, short-term pay-in-4 structure (typically 6 weeks) with strong API-led integrations. PayJustNow is better if you need pay-in-3 plus optional longer-term financing (up to 12 months) and a more app-led, QR-friendly in-store journey.

PayJustNowPayflexPayflex and PayJustNow are two of South Africa’s best-known buy now, pay later (BNPL) options. Both let consumers split purchases into instalments, typically interest-free when paid on time, while merchants pay a commission per transaction in exchange for higher conversion, larger basket sizes, and the BNPL provider taking on credit and fraud risk.
The main reason to compare them is that their instalment structures are meaningfully different. Payflex is best known for pay-in-4, usually 25% upfront and then three instalments every two weeks, completing in about 6 weeks. This shorter repayment window can suit everyday retail purchases where customers want quick, predictable repayment without long-term debt.
PayJustNow is best known for pay-in-3, typically one payment at checkout and two monthly payments. For higher-ticket purchases, PayJustNow also offers longer-term plans (up to 12 months) that are commonly interest-bearing, with terms that may vary by merchant. It also leans heavily into an app experience, including QR-based in-store payments and features like an instant-refund wallet at participating merchants.
From an Africa-wide perspective, both products are primarily South Africa focused, often requiring a South African ID and local card rails. That makes them most relevant to SA merchants and platforms selling to SA consumers, rather than pan-African checkout coverage.

Pricing
How transparent and competitive pricing is for both consumers and merchants, including instalment terms, interest, and typical fees or penalties.
Payflex
7Consumers typically pay 25% upfront then three fortnightly instalments over about 6 weeks, interest-free if paid on time. Late fees are often cited around R65 per missed instalment (capped near R195 per order), but these caps are not consistently published in an official tariff. Merchant pricing is not fully public, but gateway documents commonly indicate BNPL fees around 4.0% to 5.25% plus a fixed fee per transaction (ex VAT), suggesting moderate transparency compared to peers.
PayJustNow
6Pay in 3 is generally positioned as 0% interest with no hidden fees when paid on time. Pay in 12 (or similar extended plans) is typically interest-bearing and the rate can vary by merchant, which can complicate customer understanding and cost predictability. Merchant commission rates are usually negotiated and not publicly listed, so small merchants often need a quote to compare total cost.

Payflex
7Payflex’s core proposition is short-term pay-in-4 over about 6 weeks, which is easy to explain and keeps customers out of long repayment cycles. It also supports 2, 3, or 4 instalments in some contexts, but the flagship remains pay-in-4. For very high-ticket purchases, market guides cite typical caps (often referenced near R15,000), which may limit usefulness for premium categories depending on risk and merchant setup.
PayJustNow
8PayJustNow’s pay-in-3 can map neatly to monthly income cycles for many customers. The optional pay-in-12 style plan supports higher-ticket purchases, which can improve conversion for electronics, furniture, and larger retail baskets. The trade-off is that extended plans commonly add interest and merchant-specific terms, so the product is more flexible but less uniform.

Payflex
8Payflex is widely referenced as supporting direct API integrations (merchant, authentication, and order-style APIs) and also appears through multiple payment gateway partners in South Africa. This can reduce time-to-launch for merchants already using those gateways. Exact platform plugins (Shopify, WooCommerce, etc.) often depend on the gateway path, so merchants should confirm compatibility with their specific stack.
PayJustNow
7PayJustNow supports e-commerce integrations such as WooCommerce plugins and has visible partnerships with large South African retailers and platforms. It is also strongly oriented to in-store enablement through QR-based flows inside the consumer app. Public technical documentation for custom API builds is less visible than Payflex’s, so deeper integrations may require more sales or support engagement.

Payflex
7Payflex is used both online and in-store at participating merchants, and it includes a store directory that can drive discovery. The customer journey is typically card-based instalments with a short repayment schedule, which is straightforward at checkout. Compared to PayJustNow, fewer uniquely in-store features (like wallet refunds tied to app usage) are strongly documented publicly.
PayJustNow
9PayJustNow’s QR-based in-store payment flow is a clear differentiator for physical retail, especially where staff can present a QR and customers complete the transaction in-app. The instant-refund wallet feature can reduce friction from refund delays and encourages reuse across the partner network. This app-centric approach can be a strength for omnichannel, but it also means the customer experience depends heavily on the app.

Risk handling, settlements, and merchant value
How the provider supports merchants through upfront settlement, fraud and credit risk handling, and overall commercial attractiveness.
Payflex
8Payflex is commonly described as settling merchants upfront (minus commission) and assuming credit and fraud risk, which is a core BNPL merchant value proposition. Daily settlement is often cited for merchant cash flow, though settlement timing can still vary by agreement and gateway. Merchant fees can be materially higher than card processing, so margin-sensitive categories should model the uplift needed to justify cost.
PayJustNow
8PayJustNow is positioned as a win-win model where customers get flexible payments and merchants pay a commission per sale. Its presence on major retail platforms can add network effects and consumer familiarity, which may improve adoption. However, because merchant pricing is generally not public, it is harder to quantify ROI without a direct quote and performance assumptions.

Payflex
5Payflex is primarily South Africa focused and commonly requires South African onboarding details (such as SA ID and local card rails). It is accessible to SA merchants via local gateways, which helps domestic availability. There is limited public evidence of meaningful expansion into other African countries, so it may not fit pan-African merchants unless SA is the primary market.
PayJustNow
5PayJustNow is widely described as a South African BNPL provider and typically requires SA-specific onboarding details. Its merchant network strength is mainly within South Africa, including large retail partnerships. As with Payflex, there is limited public confirmation of availability across other African markets or local payment method support outside SA.
Verdict: which should you choose?
The verdict weighs the criterion scores against who each product serves best.Choose Payflex if your priority is a straightforward, consistently short-term BNPL offer (most commonly pay-in-4 over roughly 6 weeks) and you want a provider that appears API-forward with broad availability through South African payment gateways. This tends to fit fashion, general retail, and mid-ticket baskets where customers can comfortably clear instalments within a month or two.
Choose PayJustNow if you want pay-in-3 as a default (often easier to explain for monthly pay cycles), plus the option to support higher-ticket purchases via longer-term plans (commonly up to 12 months, typically with interest). PayJustNow’s app-led, QR-friendly in-store experience and wallet-style refunds can be attractive for omnichannel retailers.
On total cost, neither provider publishes a complete public merchant rate card, but Payflex has more visible indicative pricing via gateway partners, while PayJustNow is more quote-driven. For most merchants, the decision comes down to repayment structure (short-term vs mixed-term) and how you want BNPL to work across online and physical stores.

PayJustNow vs Payflex FAQs
Which is better for short-term instalments, Payflex or PayJustNow?
▾
For short-term instalments with a consistent structure, Payflex is typically the more direct fit because it is best known for pay-in-4 over about 6 weeks (fortnightly repayments). PayJustNow can also be short-term via pay-in-3, but it is structured monthly rather than fortnightly.
Does PayJustNow charge interest like Payflex?
▾
Both generally market their standard short plans as interest-free when paid on time (Payflex pay-in-4; PayJustNow pay-in-3). The key difference is that PayJustNow’s longer-term options (up to 12 months) are typically interest-bearing, with rates and terms that can vary by merchant, while Payflex is primarily positioned around short, interest-free plans.
Which has more transparent merchant fees?
▾
Neither consistently publishes a full public merchant rate card, but Payflex has more visible indicative pricing via some payment gateway partner documents (often showing a percentage fee plus a fixed fee per transaction). PayJustNow merchant pricing is usually quote-driven, so benchmarking often requires speaking to sales or a payment partner.
Which is better for in-store QR payments?
▾
PayJustNow is typically stronger for in-store QR-based flows, as QR scanning in the app is a central part of its in-store experience. Payflex supports in-store usage too, but the QR-led in-store journey is less prominent in publicly documented positioning.
Are Payflex and PayJustNow available outside South Africa?
▾
Both are best treated as South Africa-first BNPL providers. Public information strongly emphasizes South African onboarding and merchant coverage, and there is limited verifiable evidence of broad, multi-country African availability for either product as of 2026.
