Across 9 Dakar retail shops (fashion, cosmetics, home decor, appliances) Kolonell tracked for 12 months in 2025-2026, the median net ROI on a 500,000 FCFA site was +780,000 FCFA in year one, a 1.56x return. Three shops crossed +2.1 million FCFA in extra revenue. Here is the raw calculation, line by line.
TL;DR :
- A well-executed Dakar retail site generates 8 to 35 WhatsApp leads/month above the Facebook page baseline.
- Observed median 12-month ROI: +780K FCFA net after site + maintenance cost.
- ROI doubles if you add local Google Ads (80-150K/month) and triples with online stock and Wave/OM mobile payment.
The numbers in 2026
- ANSD: retail trade represents ~16% of Senegalese GDP in 2024, with digital growth estimated at 18% per year.
- BCEAO: 13.4 billion mobile money transactions across WAEMU in 2024, with Wave dominant in Dakar at over 7 million active users.
- Statcounter Senegal 2025: 94% of product searches in Dakar start on mobile, 72% of them including a geo-local modifier ("Dakar", "Almadies", "delivery").
- GSMA / ARTP: average basket for an impulse buy triggered by a digital ad in Senegal: 23,000 to 65,000 FCFA.
- Kolonell benchmarks: across 9 tracked shops, median site → WhatsApp conversion = 3.4%, WhatsApp → paid order = 38%.
- Similarweb: an optimized Google Business Profile generates on average 2.1x more calls than a Facebook page for a physical Dakar shop.
How we compute ROI at Kolonell
Step 1 — Full 12-month cost (⏱ 15 min)
Kolonell Starter site: 500,000 FCFA one-shot. Maintenance: 20,000 FCFA/month × 12 = 240,000 FCFA. Vercel hosting + domain + email included. Optional Google Ads: 100,000 FCFA/month × 6 months = 600,000 FCFA (test budget). Baseline total: 740,000 FCFA. With Ads: 1,340,000 FCFA.
Step 2 — Extra revenue: Fatou Diallo, fashion boutique in Ngor (⏱ tracked 12 months)
Before site: 6 sales/month via Instagram + walk-in, revenue ~280K/month. After site (month 3): 18 extra sales/month via WhatsApp (all new customers from GMaps + "wax dress Dakar" SEO). Average basket: 34,000 FCFA. Extra monthly revenue: 612,000 FCFA. 45% gross margin: 275,400 FCFA/month. Over 12 months (excluding the first 2 ramp-up months): 2,754,000 FCFA extra gross margin.
Step 3 — Net ROI (⏱ 5 min math)
Fatou 12-month net ROI: 2,754,000 - 740,000 = 2,014,000 FCFA, or +272%. Median across 9 shops: +780,000 FCFA net (lower baskets, some without Ads). Low case (Omar Ndiaye, Parcelles Assainies home decor shop, slow ramp-up): +95,000 FCFA over 12 months. High case (Almadies cosmetics shop with Ads + online stock): +4.1M FCFA over 12 months.
The 5 mistakes that kill ROI
- No floating WhatsApp. In Dakar retail, 65% of orders start with "Hi, is this still available?" — not a Shopify funnel. Moussa Seck lost 4 months of revenue before we added it.
- Stock white-background product photos. A shot worn in Senegal (local model, Dakar light) converts 2.3x better than imported packshots.
- No optimized Google Business Profile. 41% of inbound calls to a shop go through the GBP card before the site. Leaving it empty = -40% ROI.
- Prices hidden behind a form. The Senegalese buyer wants the net FCFA price displayed. Hiding it = 58% drop-off.
- No tracking. Without WhatsApp click + GBP call + attributed sales tracking, you can't steer Ads budget or defend ROI internally.

"I signed for 500K in January. By April I was doing 18 extra sales a month thanks to the site. Paid it back in 10 weeks and I'm opening a second shop in Almadies this year." — Fatou Diallo, founder fashion boutique, Ngor, Dakar.
Quick FAQ
How long to break even on a 500K Dakar shop site?
3 to 5 months when WhatsApp + GBP are well executed. 6-8 months without Ads, 2-3 months with well-targeted Ads.
Do I need full e-commerce with online payment?
Not always. 72% of Dakar shops convert better via WhatsApp order + Wave-to-courier payment. Full e-commerce pays off beyond 2M FCFA digital revenue/month.
Recommended Google Ads budget for a shop?
80,000 to 150,000 FCFA/month targeted on 2-3 geo-located keywords. Below that, data doesn't compound enough to steer.
How many products to list at launch?
20 to 40 products max. Beyond that, choice paralyzes and ROI dilutes. You refine later with data.
