The verdict in three sentences
A payment QR code at the counter removes manual number entry: the customer scans, confirms, done. The result: -90 % till errors and collection time falling from 40 seconds to 8 seconds. MoMo fees 1 to 1.5 %, QR sticker cost 0 FCFA, reconciliation automatic by reference, and merchant adoption up 25 % in 3 months.
Static QR vs dynamic QR
A static QR is a single sticker on the counter; the customer types the amount. A dynamic QR is generated per receipt with the amount pre-filled, removing the last source of error.
| Criterion | Static QR | Dynamic QR |
|---|---|---|
| Amount | typed by customer | pre-filled per receipt |
| Reference | shared | unique per sale |
| Cost | 0 FCFA (1 sticker) | terminal / till app |
| Amount error | possible | near zero |
| Reconciliation | by batch | line-by-line auto |
| Best for | small counter | volume, multiple tills |
For a small shop, a static QR is enough and costs nothing. Once volume rises or there are several tills, the per-receipt dynamic QR makes everything reliable.
The counter gains, in numbers
QR changes not just speed but the reliability of your till and your bookkeeping.
| Metric | Without QR (number entry) | With QR |
|---|---|---|
| Collection time | 40 s | 8 s |
| Entry errors | frequent | -90 % |
| Transaction fee | 1 to 1.5 % | 1 to 1.5 % |
| Hardware cost | 0 FCFA | 0 FCFA (sticker) |
| Reconciliation | manual | auto by reference |
| Queue | longer | smooth |
At a counter serving 120 customers/day, saving 32 seconds per transaction frees more than an hour of till time per day, with far fewer errors to fix in the evening.

Kofi runs a mini-market in Kumasi, 120 transactions/day, ~3,000/month. Without QR, manual entry generates about 3 % till errors, i.e. 90 errors/month to fix, each costing ~5 minutes of checking, or 7.5 hours/month lost. Switching to QR (errors -90 %), he drops to 9 errors/month, or 45 minutes. Gain: ~6.75 hours/month of admin time, plus a smoother queue that cuts peak-hour walk-aways. Static QR cost: 0 FCFA. The return is immediate.

FAQ
Does a static QR really cost 0 FCFA? Yes, a printed sticker with your merchant QR is enough. The only cost is the 1 to 1.5 % transaction fee, the same as any payment.
Static or dynamic for a small shop? Static: one sticker on the counter, the customer types the amount. Dynamic (amount pre-filled per receipt) becomes useful at higher volume or with several tills.
How much do errors really drop? By about 90 %. The main error source, manual entry of number and amount, disappears in favour of the scan.
How much time is saved per transaction? Collection drops from about 40 seconds to 8 seconds, ~32 seconds saved. At 120 customers/day, that is over an hour of till time freed.
Is reconciliation automatic? With a dynamic QR carrying a unique reference, yes: each payment reconciles itself against the sale. With a static QR, matching is done by batch.
