The verdict in three sentences
A client comparing three construction firms picks the one whose work they can see: a portfolio of costed projects weighs more than a smooth pitch. A proof-driven construction site (projects, references, certifications, tender area) costs 700,000 to 1,600,000 FCFA in 2026 and can make the difference on a contract worth over 50,000,000 FCFA. The golden rule: each project shown with budget, deadline, area and before/after photos is worth ten sales arguments.
Site cost and proof-driven structure
Construction needs no spectacular animations but a credible portfolio and a qualifying form. Here are the 2026 ranges.
| Package | Price FCFA | Price EUR | Key content | Lead time |
|---|---|---|---|---|
| Construction showcase | 700,000 | 1,070 | 5 pages, services, contact, 5 references | 8-12 d |
| Growth portfolio | 1,100,000 | 1,680 | + filterable project portfolio, team, quotes | 2-3 wk |
| Premium tenders | 1,600,000 | 2,440 | + tender area, downloadable docs, FR/EN | 3-4 wk |
| Maintenance option | 75,000/mo | 115/mo | hosting, project additions, support | ongoing |
The standard project sheet must show: structure type, client (or sector), budget, area, delivered lead time, photos. That level of detail reassures a decision-maker.
How the portfolio drives B2B conversion
A visual portfolio acts as a competence guarantee. Let us compare the effect of different proof levels on a client's decision.
| Proof level on the site | Matchmaking rate | Perceived trust | Effect on tenders |
|---|---|---|---|
| No site / Facebook page only | 3-6 % | low | often dropped |
| Showcase site without projects | 8-12 % | medium | rare shortlist |
| Portfolio of 10-20 costed projects | 18-25 % | high | frequent shortlist |
| Portfolio + references + certifications | 25-35 % | very high | credible finalist |
On an 80,000,000 FCFA tender, moving from 8 % to 25 % shortlist odds radically changes the expected win: a single won contract pays off the site dozens of times.

Mini case study
Cheikh's firm does structural work in Thies. Without a site, it answered 6 tenders a year and won 1. It invests 1,400,000 FCFA in a Growth site with a portfolio of 14 costed projects and a certifications page. In one year it is shortlisted on 5 of 9 tenders (versus 2 of 6 before) and wins 2 contracts, one worth 62,000,000 FCFA. At an 18 % margin, that contract alone yields 11,160,000 FCFA: the site pays for itself nearly 8 times over in the year.
FAQ
Which projects go in the portfolio? Your most representative and varied: one per type (housing, office, roads, renovation). 10 to 20 well-documented projects beat 50 thumbnails with no details.
Should I name the clients? With their consent, ideally yes. Otherwise state the sector ("banking group", "real estate developer") and structure type: credibility stays strong without breaching confidentiality.
Is the tender area really useful? For firms that bid often, yes. It lets them download brochure, attestations, references and certificates in one click, saving time when assembling a bid.
How long to build the portfolio? The longest part is gathering photos and figures. Allow 1 to 2 weeks of collection on the firm's side, in parallel with development.
Is bilingual useful in construction? Yes for projects funded by international donors or foreign groups, who often require documentation in English.
Let's talk about your project. A proof-driven construction site, with a portfolio of costed projects and a tender area, can move you from finalist to winner. WhatsApp +221 77 596 93 33.
