The verdict in three sentences
In Dar es Salaam in 2026, WhatsApp Business Catalog + a payment link are enough to sell without a website. Conversational conversion hits 9 % versus 2 % on a classic site, because the human touch reassures. But beyond 150 orders/month, manual handling saturates: that's when to migrate to a real site.
WhatsApp-only: what it really allows
The WhatsApp catalog shows products, prices and photos. The customer orders in the conversation and pays via a mobile-money link. Simple, but volume-limited.
| Criterion | WhatsApp-only | E-commerce site | WhatsApp + site |
|---|---|---|---|
| Startup cost | ~0 FCFA | 1,000,000 FCFA | 1,000,000 FCFA |
| Conversion | 9 % | 2 % | 6 % (mix) |
| Viable orders/month | up to 150 | unlimited | unlimited |
| Admin time/order | 6-9 min | 1-2 min | 2-3 min |
| Payment | Wave/OM link | Integrated checkout | Both |
| Analytics | Near zero | Full | Full |
Cost and switch-over
The order chatbot automates frequent questions (price, stock, delivery) and pre-fills the cart before handing off to a human to close.
| Item | 2026 cost | Effect |
|---|---|---|
| WhatsApp Business (app) | Free | Basic catalog |
| WhatsApp Business API | ~25 FCFA/message | Automation + volume |
| Order chatbot | 150,000 - 400,000 FCFA setup | -50 % admin time |
| Wave/OM payment link | 1-2 % commission | Instant collection |
| E-commerce site (switch) | from 1,000,000 FCFA | Scalability |
When each order takes 8 minutes of manual handling, 150 orders = 20 hours/month just in messaging. Beyond that, the site becomes profitable.
Mini case study
Nadia, a jewelry maker in Dar es Salaam, sells only on WhatsApp: 90 orders/month, average basket 22,000 FCFA, 9 % conversion. She spends about 12 hours/month replying.
Her sales climb to 160 orders/month: manual handling explodes to 21 hours. She invests in a chatbot (250,000 FCFA) + a site connected to WhatsApp. Admin time drops to 2.5 min/order, i.e. 7 hours. She recovers 14 hours/month and absorbs the growth without hiring. The mixed conversion settles at 6 % but on far higher volume.

FAQ
Is WhatsApp enough to start?
Yes. In 2026, a store can start at 0 FCFA with WhatsApp Business Catalog and a payment link. It's the best way to validate demand before investing in a site.
When should I migrate to a real site?
Beyond 150 orders/month, or once manual handling exceeds 15-20 hours. A site cuts admin time per order from 8 min to 1-2 min.
Does the chatbot replace the human?
No: it handles repetitive questions (price, stock, delivery) and pre-fills the order. The human steps in to reassure and close, keeping conversion high.
How much does a WhatsApp payment link cost?
Wave/Orange Money links charge 1 to 2 % commission. On a 22,000 FCFA basket, that's 220 to 440 FCFA, with no fixed fee.
Can I keep WhatsApp after getting a site?
Yes, and it's recommended: the WhatsApp + site mix captures both audiences and keeps conversational conversion on big baskets.
