The verdict in three sentences
The static QR (free, amount typed by the customer) works for low volume but multiplies entry errors and disputes. The dynamic QR (pre-filled amount, unique reference, automatic reconciliation) costs a little integration but saves time and cuts disputes by about 70%. Above 50 transactions/day, dynamic is almost always worth it.
Static or dynamic: the concrete difference
A static QR is a printed sticker made once: the customer scans, types the amount themselves, confirms. A dynamic QR is generated per sale by a till or merchant app: the amount and a unique reference are already filled in, the customer only confirms.
| Criterion (2026 estimate) | Static QR | Dynamic QR |
|---|---|---|
| Setup cost | 0 FCFA | 0 to 150,000 FCFA (integration) |
| Amount entered by | The customer | Auto pre-filled |
| Checkout time | ~20 s | ~8 s |
| Amount error rate | 5 to 12% | < 1% |
| Reference/order | None | Unique per transaction |
| Reconciliation | Manual | Automatic |
| Fake-receipt risk | High | Low |
What it changes on a 80-transaction day
The real cost of static isn't the QR: it's the time lost checking each payment and fixing mismatches.
| Item (80 transactions/day) | Static QR | Dynamic QR |
|---|---|---|
| Total checkout time | ~27 min | ~11 min |
| Amount errors/day | 4 to 9 | 0 to 1 |
| "I paid" disputes/month | 8 to 15 | 2 to 4 |
| Till reconciliation/day | 30 to 45 min | ~5 min |
| Admin hours saved/month | — | 12 to 18 h |
Wave and Orange Money both offer merchant QRs: the static QR is instant from the app, the dynamic one goes through a till integration or merchant API.
Mini case study
Awa, who runs a cosmetics shop in Dakar, handles 80 sales/day with a static QR. She averages 6 amount errors/day: half underpaid by 500 FCFA, about 1,500 FCFA lost/day, roughly 39,000 FCFA/month. She also spends 40 min/day reconciling, about 20 h/month. Switching to a dynamic QR (integration ~120,000 FCFA), she removes nearly all errors and recovers 18 h/month. Payback in under 2 months.

Does a dynamic QR cost more per transaction?
No: Wave/OM merchant fees (order of magnitude ~1%) are the same. The extra cost is only the initial integration, not per-transaction.
Can I keep static for small amounts?
Yes, many shops keep a static QR as backup and use dynamic at the main till. It's a good compromise under 30 sales/day.
Does a dynamic QR work without a computerized till?
You need at least a merchant app or small till software to set the amount. An 80,000 FCFA tablet is enough to start.
How do you avoid fake payment receipts?
The dynamic QR's unique reference is verified on the merchant side: a fake screenshot matches no real transaction, unlike static.
At what volume should I move to dynamic?
From about 50 transactions/day, the reconciliation time saved exceeds the integration cost within a few weeks.
