The verdict in three sentences
A static QR (customer types the amount) is free and instant to display, but produces 5 to 12 % entry errors and an end-of-day reconciliation nightmare. A dynamic QR (amount pre-filled, unique reference) drops below 1 % error, cuts checkout time from 25 to 9 seconds and auto-matches 95 %+ of payments. For a high-volume store the dynamic QR wins; for an occasional small stall the static one is enough.
Static vs dynamic: what happens at the counter
A static QR is just a sticker at the till: the customer scans, types the amount themselves, confirms. Fast to set up, but every manual entry is an error source — wrong amount, wrong reference, forgotten payment. A dynamic QR is generated on the fly for each sale: the amount and a unique reference are already encoded, so the customer only confirms.
| Metric | Static QR | Dynamic QR |
|---|---|---|
| Amount entered by | The buyer | Pre-filled |
| Amount error rate | 5-12 % | < 1 % |
| Checkout time | ~25 s | ~9 s |
| Auto-reconciliation | 40-60 % | 95 %+ |
| Order reference | None | Unique per sale |
| Setup cost | Near zero | Terminal/API required |
| Best for | Stall, low volume | Store, high volume |
The channels: M-Pesa Till, MoMo Pay and Wave
Every mobile-money solution offers both formats. In East Africa (M-Pesa Till/Buy Goods, MoMo Pay), the dynamic Till is standard for structured retailers. In Francophone West Africa (Wave, Orange Money), the static merchant QR is very common for small shops.
| Channel | Dominant type | Merchant fee | Auto-match | Settlement speed |
|---|---|---|---|---|
| M-Pesa Buy Goods (Till) | Dynamic | 0.5-1.5 % | High | Near instant |
| MoMo Pay | Dynamic | 1.0-2.0 % | High | Instant |
| Wave (static QR) | Static | 1.0-1.5 % | Medium | Instant |
| Wave (dynamic QR) | Dynamic | 1.0-1.5 % | High | Instant |
| Orange Money (Merchant) | Both | 1.5-2.0 % | Medium-high | Instant |
Merchant fees are comparable; what truly separates the two formats is the auto-reconciliation rate in accounting. A static QR forces you to manually match each payment against each sale — several hours a week.
Mini case study
Ibrahim runs a grocery in Abidjan: 120 checkouts/day, average ticket 4,500 FCFA. With a static QR, 8 % of payments have a mis-typed amount — about 10 payments/day to correct or refund. On checkout time, 25 s per transaction vs 9 s dynamic: across 120 sales he loses (25-9) × 120 = 1,920 seconds/day, i.e. 32 minutes of avoidable queueing.
Switching to dynamic QR, he eliminates ~9 errors/day and reclaims 32 minutes of flow. Over a 26-day month that's ~14 hours of staff time and 260 corrections avoided — more than enough to justify an 80,000 FCFA terminal.

FAQ
How many payments are mis-entered with a static QR?
Between 5 and 12 % depending on amount and footfall. At 100 sales/day that's 5 to 12 daily corrections, each costing time and sometimes a refund.
Is the dynamic QR really faster?
Yes: checkout time drops from about 25 seconds to 9 seconds, since the customer just confirms a pre-filled amount. In a queue the difference is very visible.
Do I need a special terminal for dynamic QR?
Not always: a till connected to the provider's API is enough to generate a QR per sale. Hardware cost is around 50,000 to 100,000 FCFA as a 2026 order of magnitude.
Which format makes accounting easiest?
Dynamic, with 95 %+ auto-reconciliation vs 40-60 % for static. Each payment carries a unique reference tied to the sale, removing manual matching.
Does static QR still have a use?
Yes, for a small stall, a market or occasional use: free, instant, no hardware. Below 20-30 sales/day the error stays manageable manually.
