The verdict in three sentences
The static QR is free, instant and perfect for low volume, but it forces manual amount entry and complicates reconciliation. The dynamic QR generates a unique identifier per transaction, which cuts reconciliation errors by around 60% and automates accounting. In 2026, 70% of Dakar merchants stay on static for simplicity, but dynamic becomes essential the moment you track stock or run multiple tills.
Static vs dynamic: the comparison
The static QR is a single code tied to your Wave Business account: the customer scans, enters the amount, pays. The dynamic QR is generated on the fly by your POS for each order, with amount and reference pre-filled.
| Criterion | Static QR | Dynamic QR |
|---|---|---|
| Number of codes | 1 account | 1 ID per transaction |
| Amount entry | Manual (customer) | Automatic |
| Setup cost | Free | 150,000 – 300,000 FCFA (dev) |
| Reconciliation | Manual | Automatic |
| Reconciliation errors | Baseline | −60% |
| Dakar adoption 2026 | ~70% of merchants | Growing |
Static wins on cost and speed to start. Dynamic wins as soon as each payment must map to a specific order without human intervention.
When to switch to dynamic
The trigger is not gross revenue but the number of transactions and points of sale. A solo artisan with 20 sales a day is perfectly served by a displayed static QR. A three-till shop managing shared stock spends hours reconciling payments: dynamic pays off fast.
| Merchant profile | 2026 recommendation |
|---|---|
| Solo seller, low volume | Free static QR |
| Single-till shop, light stock | Static + manual tracking |
| Multi-till or e-commerce | Dynamic QR per order |
| Franchise / multiple outlets | Dynamic + central dashboard |
| Frequent till errors | Dynamic (−60% errors) |
Dynamic usually connects through the Wave API — the same one used for online Checkout: a 150,000 to 300,000 FCFA investment that serves both counter and web.
Mini case study
Fatou, who runs a grocery in Dakar with two tills, handles 900 Wave payments a month on a static QR. She sees about 5% reconciliation gaps — 45 transactions to trace by hand each month, two hours of weekly work. Switching to dynamic QR (250,000 FCFA dev cost), she cuts gaps by 60%, drops to 18 transactions to check and recovers over an hour a week — the investment is absorbed within a few months of time saved.

FAQ
Is the Wave static QR really free?
Yes, a Wave Business account provides a static QR with no setup fee. You only pay the merchant cash-in commission (ballpark ~1% in 2026) on payments received.
Why does dynamic reduce errors?
Because the amount and an order reference are pre-filled: the customer cannot enter the wrong sum, and each payment auto-maps to its order. The result is about 60% fewer reconciliation errors.
How much does a dynamic QR cost?
Integration development runs between 150,000 and 300,000 FCFA depending on your POS. Generating the codes itself adds no Wave fee beyond the usual commission.
What do most merchants use in 2026?
About 70% of Dakar merchants stay on the static QR for its simplicity. Dynamic grows mainly among multi-till shops and sellers tracking stock.
Can I use both?
Yes. Many keep a static QR as a counter backup and use dynamic for tracked orders and e-commerce. The same Wave API powers both uses.
