The verdict in three sentences
A B2B matchmaking platform between buyer SMEs and approved suppliers in West Africa lives or dies on trust: verified profiles, serious quote requests and fast replies. The realistic budget is 12,000,000 to 25,000,000 FCFA before tax (about 18,300 to 38,100 EUR), for 16 weeks of development and about 150,000 FCFA per month of hosting (around 230 EUR). The business model relies on supplier subscriptions of 15,000 to 50,000 FCFA per month (23 to 76 EUR): 300 paying subscribers comfortably cover operating costs.
Functional architecture: what to build
The core flow is simple: an SME posts a request for quotation (product, quantity, deadline, city), relevant verified suppliers are notified, they reply with a price, and the buyer compares and chooses. Everything else supports that flow.
| Module | Role | Launch version | Estimated effort |
|---|---|---|---|
| Verified company profiles | Tax ID, trade register, certificates, verified badge | Manual check by the team | 2 weeks |
| Supplier directory | Categories, areas served, capacity | 40 categories, 8 WAEMU countries | 2 weeks |
| Quote requests | Posting, targeting, priced replies | Offer comparison | 3 weeks |
| Secure messaging | Buyer and supplier exchanges | Text and attachments | 1.5 weeks |
| Supplier subscriptions | Plans, recurring payment | Wave, Orange Money, card | 2 weeks |
| Notifications | New request alerts | Email, SMS, WhatsApp | 1 week |
| Back office | Moderation, approval, statistics | Admin dashboard | 2.5 weeks |
Technically, a modular monolith (Next.js, PostgreSQL, object storage for documents, a job queue for notifications) is more than enough for the first 5,000 companies. Microservices do not belong in the launch: they double the cost with no benefit at that volume.
Budget per tier and running costs
Figures are 2026 estimates for a Dakar-based team.
| Item | Launch | Growth | Regional |
|---|---|---|---|
| Scope | Quotes, profiles, subscriptions | + messaging, ratings, API | + multilingual, public tenders |
| Countries covered | Senegal | Senegal, Côte d'Ivoire, Mali | 8 WAEMU countries |
| Payments | Wave, Orange Money | + bank card | + transfer and company invoicing |
| Budget before tax | 12,000,000 FCFA (18,300 EUR) | 18,000,000 FCFA (27,440 EUR) | 25,000,000 FCFA (38,110 EUR) |
| Lead time | 12 weeks | 16 weeks | 20 weeks |
| Monthly hosting | 90,000 FCFA | 150,000 FCFA | 250,000 FCFA |
| Monthly maintenance | 150,000 FCFA | 250,000 FCFA | 400,000 FCFA |
Add mobile money fees (1 to 2% depending on operator and volume), SMS (about 15 to 25 FCFA each) and the human cost of profile verification, often a full-time role from 300 suppliers.
The supplier business model
Three plans cover most cases: free Discovery (3 quote replies per month), Pro at 15,000 FCFA (unlimited replies, verified badge) and Premium at 50,000 FCFA (featured listing, statistics, multiple users). Buyers stay free: they create the value for suppliers, and any entry friction drains the platform of requests.
Mini case study
Moussa, an entrepreneur in Dakar, launches the Growth tier at 18,000,000 FCFA before tax. His monthly costs reach 400,000 FCFA (hosting and maintenance) plus 350,000 FCFA for a verification officer, or 750,000 FCFA.

After 12 months, he targets 250 paying suppliers: 200 on Pro at 15,000 FCFA and 50 on Premium at 50,000 FCFA, or 5,500,000 FCFA of monthly revenue. After operating costs, the margin is 4,750,000 FCFA per month. The initial investment is repaid in under 4 months once that level is reached, but the real challenge remains how fast he acquires the first 100 active buyers.
FAQ
What budget for a B2B matchmaking platform in West Africa in 2026?
From 12,000,000 to 25,000,000 FCFA before tax depending on scope and number of countries. A version covering Senegal, Côte d'Ivoire and Mali lands around 18,000,000 FCFA (27,440 EUR).
How do you verify suppliers?
By checking the tax ID or trade register, tax certificates and a validation call. Count 20 to 30 minutes per file, so a dedicated role beyond 300 suppliers.
Can subscriptions be collected through Wave and Orange Money?
Yes, both are integrated from the Launch tier, with fees of 1 to 2%. Bank cards are added for international suppliers.
Which technical architecture should we choose?
A modular monolith with PostgreSQL, hosted for 90,000 to 150,000 FCFA per month, handles several thousand companies. Splitting into services only makes sense beyond that.
How long until launch?
Sixteen weeks for the Growth tier, including two weeks of beta with 30 suppliers and 10 pilot buyers.
