The verdict in three sentences
For a developer marketing 3 off-plan projects in Dakar and Diamniadio and selling 40% of its units to the diaspora (Dubai, Paris, Montreal, New York), an off-plan sales website costs 4 to 9 million FCFA (about EUR 6,100 to 13,700) in 2026, delivered in 8 to 10 weeks. The three features that sell are a live unit availability grid, a 3D tour (about 600,000 FCFA, EUR 915, per project) and video appointment booking across time zones. Done right, the site brings the cost of a diaspora reservation down to 2 to 3 times less than a stand at a property fair abroad.
What an overseas buyer wants to see before paying a deposit
A buyer living in Dubai or Milan will not visit the site before signing. They look for proof: construction progress, land title, guarantees, payment schedule. Each block of the website answers a specific objection.
| Feature | Objection removed | Indicative 2026 cost |
|---|---|---|
| Live unit grid (available, on hold, sold) | "Maybe nothing is left" | 800,000 to 1,500,000 FCFA |
| 3D tour per project | "I can't picture the space" | 600,000 FCFA per project |
| Monthly photo and video site log | "Is construction really moving?" | 300,000 to 600,000 FCFA |
| Legal page (land title, permit, off-plan contract, notary) | "Is the land secured?" | 250,000 to 500,000 FCFA |
| Payment schedule and mortgage simulator | "How much per month, and until when?" | 400,000 to 800,000 FCFA |
| Multi-time-zone video booking | "Nobody answers during my hours" | 200,000 to 450,000 FCFA |
| Buyer portal (contracts, payment calls, receipts) | "I want to track my file remotely" | 900,000 to 1,800,000 FCFA |
The unit grid must be connected to the sales tool (CRM or shared spreadsheet): a sold unit still shown as "available" costs more in credibility than it earns in leads.
Three budget levels
| Level | Budget FCFA | Projects | Key features | Timeline |
|---|---|---|---|---|
| Essential | 4,000,000 to 5,500,000 | 1 to 3 | Project pages, unit grid, forms, WhatsApp | 8 weeks |
| Advanced | 5,500,000 to 7,500,000 | 3 to 5 | + 3D tour, simulator, video calls, FR/EN | 9 weeks |
| Premium | 7,500,000 to 9,000,000 | 5 or more | + buyer portal, reservation fees paid by Wave or card, CRM | 10 weeks |
Add 150,000 to 300,000 FCFA (EUR 230 to 460) per month for hosting, maintenance and unit updates, plus a Meta and Google ads budget of 1,000,000 to 2,500,000 FCFA per month targeting the diaspora in France, Italy, Spain, the UAE and the United States.
Cost per reservation: website and ads versus diaspora property fairs
Diaspora property fairs in Paris or Dubai are useful for awareness, but expensive per signed reservation. Order of magnitude for a mid-sized developer in 2026:
| Channel | Spend | Qualified contacts | Reservations | Cost per reservation |
|---|---|---|---|---|
| Diaspora fair abroad (stand, flights, hotel, 3 days) | 12,000,000 FCFA | 180 | 6 | 2,000,000 FCFA |
| Website + targeted ads (3 months) | 4,500,000 FCFA ads + 1,500,000 FCFA site amortisation | 260 | 8 | 750,000 FCFA |
| Website + video calls + WhatsApp follow-up (3 months) | 6,000,000 FCFA | 320 | 11 | 545,000 FCFA |
| Diaspora referral agents only | 3% of unit price | 60 | 4 | 1,050,000 FCFA on a 35,000,000 FCFA unit |
| Word of mouth, no website | Low | Not measurable | 2 to 3 | Not measurable |
The best result usually comes from combining them: the fair collects names, the website and video calls turn those contacts into reservations in the following weeks.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Modou, sales director of a Dakar developer, markets 3 projects, 180 units at an average 35,000,000 FCFA. The diaspora buys 40% of the units, with a growing share from the Gulf. He invests 7,200,000 FCFA in an Advanced website and 2,000,000 FCFA per month in targeted ads.
Over 12 months, the website generates 34 diaspora reservations, against 14 the previous year with two fairs abroad. Total cost: 7,200,000 + 24,000,000 = 31,200,000 FCFA, about 920,000 FCFA (EUR 1,400) per reservation, against 1,700,000 FCFA before. The 20 extra reservations represent 700,000,000 FCFA of secured revenue, and the website pays for itself with the first sale.
FAQ
How much does an off-plan developer website cost in 2026?
Budget 4 to 9 million FCFA (EUR 6,100 to 13,700) depending on the number of projects and features. An Essential site for 1 to 3 projects starts around 4,000,000 FCFA, delivered in 8 weeks.
Is a 3D tour essential for off-plan sales?
For overseas buyers it replaces the impossible physical visit. Budget about 600,000 FCFA per project; it often extends time on page by 2 to 4 minutes.
Can reservation fees be collected online?
Yes, by Wave, Orange Money or card through Stripe, with an automatic receipt. The main deposit usually goes through the notary, as set out in the reservation contract.
How do we keep the unit grid up to date?
By connecting it to the CRM or a spreadsheet shared with the sales team. An update within 24 hours of each hold avoids double bookings.
Do we need one website per project?
Rarely. A single site with a rich page per project costs 30 to 40% less and concentrates search visibility on the developer's brand.
