Enterprise fraud detection software costs hundreds of thousands per year. For SA SMEs, that's out of reach. But lighter-weight AI-powered fraud checks have become affordable — and in specific situations they pay for themselves many times over.
Where SME fraud usually happens
- E-commerce: stolen card payments, chargebacks, triangulation fraud
- Invoice fraud: a fake supplier email redirects payment details
- CEO / payment fraud: attackers impersonate executives to authorise payments
- Account takeover: customer accounts compromised and used for unauthorised purchases
What AI fraud tools actually do
- Cross-check transactions against behavioural patterns (time, location, velocity)
- Flag emails with payment-detail changes for human review
- Detect unusual login patterns and suggest MFA challenges
- Classify transactions into risk bands for automated or manual handling
What they cost for SMEs
Integrated payment-gateway fraud layers: free to a few hundred rand/month (Stripe, Peach, Yoco all include baseline ML fraud checks). Standalone fraud tools: R2 000–R8 000/month. Custom SME fraud layers: R4 000–R15 000/month.
Is it worth it?
If your business processes more than roughly R200 000/month in card payments, or you handle more than 20 invoices per month, yes. Below that threshold, POPIA-aligned internal process (dual-approval for payments over a threshold, separate comms channels for payment changes) gets you 80% of the benefit at 0% of the cost.
SME fraud isn't rare. It's just unreported. Most small businesses discover it only after the money is gone — at which point AI has limited value.
