The verdict in three sentences
The Wave QR code spares you a bank POS rental at 15,000–25,000 FCFA/month and collects in person with no hardware. The static QR is free but forces manual reconciliation and carries an amount-entry risk; the dynamic QR via API shows the exact amount and behaves like a modern till. For a shop at 320,000 FCFA/day, the right choice depends on your volume and your need for accounting traceability.
Three ways to collect with Wave in-store
Wave offers several in-person payment mechanics. All rely on the customer's smartphone, but they differ sharply in delay, error rate and accounting effort.
| Criterion | Static QR | Dynamic QR (API) | Payment link |
|---|---|---|---|
| Monthly cost | 0 FCFA | Integration + ~1% | ~1% |
| Amount pre-filled | No (customer types) | Yes | Yes |
| Collection delay | Instant | Instant | Instant |
| Amount error rate | ~3–5% | < 0.5% | < 0.5% |
| Reconciliation | Manual | Automatic | Automatic |
| Best for | Small shop | High-volume till | Remote sales |
The static QR is perfect to start: you print the code, the customer scans, types the amount and pays. But at 40 transactions/day, a 3–5% entry error means 1 to 2 wrong payments daily to fix by hand.
The real cost versus a bank POS
| Item | Bank POS | Wave static QR | Dynamic QR API |
|---|---|---|---|
| Hardware rental | 15,000–25,000 FCFA/month | 0 FCFA | 0 FCFA |
| Transaction commission | 1.5–2.5% | ~1% | ~1% |
| Fixed fee/transaction | 50–100 FCFA | 0 FCFA | 0 FCFA |
| Payout delay | T+1 to T+3 | Instant | Instant |
| Reconciliation | Automatic | Manual | Automatic |
On 320,000 FCFA/day, about 8,000,000 FCFA/month collected, a POS at 2% would cost 160,000 FCFA/month in commission plus rental. The Wave QR at 1% costs 80,000 FCFA with no rental — a monthly saving of roughly 95,000 to 105,000 FCFA.
Mini case study
Ibrahim runs a hardware store in Dakar: 40 transactions/day at 8,000 FCFA average, i.e. 320,000 FCFA/day and about 8,000,000 FCFA/month. With a static QR, he pays 80,000 FCFA in Wave fees and zero rental, but spends 30 minutes/day reconciling amount errors. Switching to a dynamic QR via API (wired to his till), his error rate drops below 0.5%, he recovers 10 hours/month of admin work, at almost identical fees.

FAQ
Is the Wave static QR really free?
The QR itself costs nothing to generate and display. You only pay the collection commission (~1%) on amounts received, with no hardware rental.
Why move to dynamic QR if static works?
The dynamic QR pre-fills the amount, dropping the error rate from ~3–5% to under 0.5% and automating accounting reconciliation. At high volume, the time saved is decisive.
How much does dynamic QR API integration cost?
As a 2026 ballpark, plan a few days of development depending on your till system. The investment pays off quickly beyond 30 transactions/day.
Can I keep the static QR as backup?
Yes. Many shops display a static QR as a fallback to the dynamic system, useful during a network outage or till failure.
