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.
The Quick Comparison
| PayJustNow | Payflex | Mobicred | |
|---|---|---|---|
| Model | Pay in 3 | Pay in 4 | Revolving credit |
| Interest | 0% | 0% | Interest charged |
| Payments | 3 × monthly | 4 × fortnightly | Monthly minimum |
| Credit check | Soft check | Soft check | Full credit check |
| Approval time | ~60 seconds | ~2 minutes | Up to 24–48h |
| Max purchase | R30,000 | R8,000 | Up to R50,000 |
| First payment | At purchase | At purchase | First statement |
| Late fee | R120/month | R75 once-off | Standard interest |
PayJustNow — Best for Tech Purchases Under R30,000
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: Tech purchases between R500 and R30,000. Gaming PCs, GPUs, headphones, sim racing wheels, TVs, laptops. The R30,000 cap covers almost everything on a tech wishlist.
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 (R15,000+ gaming PC builds) where you need more than R30k, 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 PayJustNow and 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 R30,000 cap that covers the vast majority of what South African tech buyers need. It’s what CellularFin offers at checkout — and it’s the reason you can buy a R2,699 sim racing wheel for R883/month instead of laying out the full amount upfront.
Use Payflex when your purchase is under R2,000 and you get paid fortnightly. Use Mobicred when your purchase exceeds R30,000 or 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.
