Buy Now Pay Later (BNPL) has changed how South Africans buy tech. Instead of saving for 3 months to buy a R3,000 GPU or a R5,000 gaming headset, you can take it home today and spread the cost. But not all BNPL options are equal — and choosing the wrong one can cost you more than you expect.
Here’s an honest, side-by-side breakdown of South Africa’s three biggest BNPL players: PayJustNow, Payflex, and Mobicred.
At CellularFin you can pay later with PayJustNow (3 interest-free payments) or Mobicred (choose it in our card checkout). We don’t offer Payflex, but it’s included below so you can compare all three.

| Late fee | R120/month | R75 once-off | Standard interest |
PayJustNow — Best for Most Tech Purchases
PayJustNow splits your purchase into 3 equal payments: one at checkout, one 30 days later, one 60 days later. Zero interest, zero fees if you pay on time. The application takes about 60 seconds — you need a SA ID, a bank account, and a debit or credit card.
The key advantage: monthly payment cadence matches how most South Africans get paid. One payment per salary cycle feels manageable in a way that fortnightly payments (Payflex’s model) sometimes doesn’t.
Best for: Most tech purchases: gaming PCs, GPUs, headphones, sim racing wheels and laptops. How much you can spend is set by the limit PayJustNow approves for you, not a fixed store cap.
Watch out for: The R120/month late fee is steep compared to Payflex’s R75 once-off. If your debit order bounces, it adds up. Set a reminder or use a card with the funds available.

Payflex — Best for Smaller Purchases, Fortnightly Payers
Payflex splits into 4 payments over 6 weeks — 25% today, then 25% every two weeks. Zero interest on the base plan. The R8,000 cap is the main limitation for tech buyers, and the fortnightly cadence doesn’t suit everyone’s pay cycle.
Best for: Smaller tech items — phone cases, earbuds, accessories, peripherals. Anything under R2,000 where you want to spread across two paydays rather than three months.
Watch out for: The R8,000 cap rules it out for GPUs, gaming PCs, and most high-end headphones. If your purchase is above that, you need PayJustNow or Mobicred.
Mobicred — Best for High Spend, Long-Term Purchases
Mobicred is a revolving credit account, not a per-purchase split. You apply for a credit limit (up to R50,000), get approved via full credit check, and your limit is available across any Mobicred-accepting store. You pay a monthly minimum — and interest accrues on the outstanding balance.
Best for: Large purchases such as a full gaming PC build, or buyers who want a revolving credit line they can use across multiple stores without re-applying each time.
Watch out for: Interest. Mobicred charges interest on your balance — unlike pay-in-3 with PayJustNow or pay-in-4 with Payflex, which are genuinely 0% if you pay on time. If you carry a balance for 3+ months, you’ll pay meaningfully more than the purchase price. Treat it like a credit card, not a free loan.
Which Should You Use for Buying Tech in South Africa?
For most tech purchases, PayJustNow is the default choice. Zero interest, monthly payments, 60-second approval, and a spend limit that’s set when you’re approved. It’s what CellularFin offers at checkout, and it’s how you can take home a R2,649 sim racing wheel for 3 payments of R883 instead of paying the full amount upfront.
Payflex suits small purchases if you get paid fortnightly (it isn’t available at CellularFin). Use Mobicred when you want a revolving limit to use across multiple stores — but only if you’re confident you’ll pay it off quickly to avoid interest.
