The verdict in three sentences
WhatsApp Business turns a simple chat into a mini-store: catalog, cart and Wave payment link at 0 FCFA cost and 1 % fees. With a 70-90 % response rate and an 8-15 % conversational conversion, the channel converts far better than a site visited once then forgotten. The key isn't technology but the journey: message → catalog → Wave link → confirmation, never leaving the app.
The conversational sales journey
| Step | Action | Tool | Friction removed |
|---|---|---|---|
| 1. Contact | Customer messages or replies to a status | No app to install | |
| 2. Discovery | Send the product catalog | WhatsApp catalog | No website needed |
| 3. Selection | Customer adds to cart | WhatsApp cart | Instant clear quote |
| 4. Payment | Wave link with pre-filled amount | Wave link (1 %) | Zero amount error |
| 5. Confirmation | Notification + order recap | Proof and tracking |
Every step stays inside WhatsApp, where the customer already spends their day. The catalog avoids copy-pasting photos, the cart generates a clean quote, and the Wave link closes the sale without renegotiation.
The channel's key figures
| Indicator | 2026 ballpark | Comment |
|---|---|---|
| Message response rate | 70-90 % | Far above email |
| Conversational conversion | 8-15 % | 3 to 5x a cold site |
| Wave payment fee | ~1 % | Link at 0 FCFA |
| Payment-link cost | 0 FCFA | Unlimited generation |
| Average basket | ~12,000 FCFA | Varies by niche |
| Expected reply time | < 15 min | Beyond that, lost sale |
The 8-15 % conversion is the decisive figure: on WhatsApp the customer is already engaged and the Wave link removes payment friction.
Monthly revenue calculation
Take a seller with 300 active contacts pushing one offer a month. At a 10 % conversion, that's 30 orders. At a 12,000 FCFA average basket: 360,000 FCFA monthly revenue. Wave fees at 1 %: 3,600 FCFA. Acquisition cost is near zero since the contacts are already there.
Mini case study
Aïssatou sells jewelry in Dakar via WhatsApp with 300 active contacts. Before, she sent photos one by one and noted orders by hand, losing sales for lack of a clear recap.
By structuring a WhatsApp catalog + a Wave link per order, she moves from an estimated 6 % conversion (18 sales, 216,000 FCFA) to 10 % (30 sales, 360,000 FCFA). Gain: +144,000 FCFA/month = +1,728,000 FCFA/year, for 0 FCFA of tooling and 3,600 FCFA of Wave fees. The only investment: structuring the catalog and replying within 15 minutes.

FAQ
Is the WhatsApp catalog free?
Yes, the WhatsApp Business catalog and cart are free. You only pay Wave fees of about 1 % at collection, the payment link costing 0 FCFA.
Why does WhatsApp convert better than a site?
Response rate reaches 70 to 90 % and conversational conversion 8 to 15 %, because the customer is already engaged in a chat. A site visited once with no follow-up converts far lower.
How do I collect without amount errors?
Generate a Wave link with the amount pre-filled from the cart: the customer just confirms. That brings the data-entry error rate to zero and speeds the sale.
What reply time should I target?
Under 15 minutes ideally. Beyond that the customer cools off or buys elsewhere; speed is the top conversion factor on this channel.
Do I need a site on top of WhatsApp?
WhatsApp is enough to start and collect, but a mini catalog site boosts credibility, SEO and reassurance for new customers. The two complement each other.
