The verdict in three sentences
For a physical shop in Senegal in 2026, the mobile money QR (Wave, Orange Money) beats the card POS on nearly every axis: near-zero acquisition cost, lower commission and instant settlement. The POS only matters if a meaningful share of your customers pay with international cards (tourists, expats, large accounts). For 95 % of neighbourhood shops the QR is enough, and till reconciliation becomes the only real project.
Acquisition cost and commission: the match-up
The QR has no hardware to buy: a printed sticker or the cashier's phone screen is enough. The POS stacks purchase or rental, setup fees and a higher card commission.
| Criterion (2026 estimate) | Wave/OM QR | Card POS |
|---|---|---|
| Acquisition cost | 0 FCFA (sticker/screen) | 50,000 – 150,000 FCFA |
| Monthly rental | 0 FCFA | 5,000 – 15,000 FCFA/mo |
| Commission/transaction | ~1 % (often 0 % customer side) | 1.5 – 3 % |
| Settlement delay | Instant | T+1 to T+2 |
| Equipped customers | >70 % own a wallet | <30 % own a card |
| Outage / connection | Light GSM network | Bank link required |
On 100 transactions of 5,000 FCFA, i.e. 500,000 FCFA collected, the QR at 1 % costs ~5,000 FCFA, the POS at 2.5 % costs ~12,500 FCFA, before rental.
Cash flow and till reconciliation
The QR's instant settlement changes cash flow: money is available the same evening, not at T+1. In return, without a process, a cashier can validate an order before the payment lands. The fix: show the merchant confirmation (notification or dashboard) before handing over the product, and reconcile the daily till total against the wallet statement every evening.
| Reconciliation item | Risk | Best practice |
|---|---|---|
| Announced but unreceived payment | Dead loss | Wait for merchant notif |
| Customer duplicate | Dispute | Unique reference per ticket |
| Fees deducted at source | Accounting gap | Book the commission |
| Refund | Till shortfall | Reversal log |
Mini case study
Fatou runs a grocery in Pikine and takes about 900,000 FCFA/month. With a POS rented at 10,000 FCFA/month and 2.5 % commission she pays 10,000 + 22,500 = 32,500 FCFA/month. Switching to Wave QR at ~1 % she drops to ~9,000 FCFA/month, saving 23,500 FCFA/month (282,000 FCFA/year) while getting paid the same day.

FAQ
Does the QR work without the customer's mobile data?
The customer needs their app or a code; if data is down, USSD steps in on most wallets. The merchant gets the confirmation within seconds over the GSM network.
Can I keep the POS and add a QR?
Yes, and it's often smart: QR by default (cheaper) and POS for foreign cards. You optimise commission on 90 % of payments.
What is the real merchant commission in 2026?
Order of magnitude: around 1 % on Wave depending on profile, variable on OM. Ask for your grid as it depends on negotiated monthly volume.
How do I avoid fake payments?
Never hand over goods on a mere screenshot: require the notification on the merchant account or a real-time till dashboard.
