The verdict in three sentences
A merchant QR code is the fastest way to collect in person with no hardware: zero cost versus 15,000-30,000 FCFA/month for a bank POS terminal. The real decision is static vs dynamic: static is free and instant but forces the customer to type the amount, while dynamic pre-fills the amount and a unique reference, making reconciliation automatic. In 2026, a dynamic QR with an encoded reference cuts accounting reconciliation errors roughly tenfold.
Static QR vs dynamic QR
The two formats meet different needs. Static suits a small low-ticket shop; dynamic wins the moment you want traceability and automatic reconciliation.
| Criterion | Static QR | Dynamic QR |
|---|---|---|
| Amount | Typed by customer | Pre-filled |
| Order reference | None | Unique, encoded |
| Reconciliation | Manual | Automatic |
| Reconciliation error rate | 3-8 % | 0.3-0.8 % |
| Cost | Free | Free (via API) |
| Best for | Market stall, corner shop | E-commerce, restaurant, invoice |
The real cost: QR versus POS terminal
QR does not just replace a gesture, it removes a structural cost line. Let's compare over one year for a merchant collecting the equivalent of 6,000,000 FCFA/month.
| Item | Bank POS terminal | Mobile money QR |
|---|---|---|
| Hardware rental | 15,000-30,000 FCFA/month | 0 |
| Fee per transaction | 1.5-2.5 % | 0-1 % (by plan) |
| Settlement delay | 24-72 h | Instant to next day |
| Annual hardware cost | 180,000-360,000 FCFA | 0 |
| Outage / bank-network dependency | Yes | Mobile network only |
| Reconciliation | Bank statement | Per-transaction reference |
Mini case study
Awa runs a ready-to-wear shop, average ticket ~25,000 FCFA, 240 sales/month. She rented a POS at 20,000 FCFA/month plus 2 % fees, i.e. 20,000 + 120,000 = 140,000 FCFA/month in collection costs. Switching to a dynamic QR with an encoded reference, she removes the rental and drops to about 1 % fees: 60,000 FCFA/month, i.e. 80,000 FCFA/month saved, nearly 960,000 FCFA/year, plus automatic reconciliation by reference.

What is the difference between static and dynamic QR?
A static QR is a fixed code where the customer types the amount: free but with no reference, so reconciliation is manual. A dynamic QR pre-fills the amount and a unique per-order reference, automating matching and cutting the error rate from 3-8 % to under 1 %.
Does a QR code cost anything?
Generating a QR is free with major mobile money providers; you only pay a per-transaction fee (often 0 to 1 %). That is the key advantage over a bank POS, rented at 15,000-30,000 FCFA/month with 1.5-2.5 % fees.
How do you reconcile QR payments automatically?
By encoding a unique reference in each dynamic QR. Your system receives the webhook carrying that reference, matches it to the order and marks the payment confirmed, with no manual intervention.
Does QR work without a terminal or complex merchant app?
Yes: a simple printed display (static) or a screen (dynamic) is enough. The customer scans with their mobile money app and confirms. No dedicated hardware is required, only a connection to receive the confirmation.
Can I refer a QR collection solution to other merchants?
Yes, through the Kolonell referral program. Every merchant you introduce who deploys a shop or e-commerce with QR collection earns you a commission: 15 % + 5 % recurring on showcase, 12 % on e-commerce.
