The verdict in three sentences
A supplier portal for a retail chain in Dakar costs 20 to 45 million FCFA excl. tax (about EUR 30,000 to 69,000) in 2026, rolled out in 5 months. With 25 stores and 400 suppliers, the return comes mainly from automatic order, delivery and invoice matching, which cuts disputes by about 30% and speeds up payments. The portal must work on 3G and on phones, because many local suppliers have neither an ERP nor a dedicated computer.
Functional scope and cost
In a Senegalese chain, purchasing mixes food multinationals, Dakar wholesalers and small producers (Niayes market gardeners, local cereal processors). The portal must serve all three profiles with the same rigor.
| Module | Content | Indicative cost excl. tax 2026 |
|---|---|---|
| Product onboarding | Item records, EAN codes, photos, prices, buyer approval | 3,000,000 to 6,500,000 FCFA |
| Digital purchase orders | Sent per store or warehouse, acknowledgment, quantity confirmation | 4,000,000 to 8,500,000 FCFA |
| Delivery notices and receiving | Delivery note, quantity gaps, breakage, expiry dates | 3,000,000 to 6,000,000 FCFA |
| Invoice matching (3-way) | Order, receipt, invoice, blocking of discrepancies | 4,000,000 to 9,000,000 FCFA |
| Supplier area: payments and disputes | Payment schedule, invoice status, dispute tickets | 2,500,000 to 5,500,000 FCFA |
| ERP integration and 3G degraded mode | ERP API, offline sync, SMS | 2,000,000 to 6,000,000 FCFA |
| Security, hosting, testing, training | Roles, backups, training for 400 suppliers | 1,500,000 to 3,500,000 FCFA |
Total: 20 million FCFA for onboarding, orders and basic matching; 45 million FCFA with full ERP integration, detailed handling of delivery gaps and an offline mobile portal. Maintenance and hosting: 3 to 6 million FCFA a year.
What the portal changes in the numbers
| Indicator (2026 order of magnitude) | Before (email, paper, WhatsApp) | With the portal |
|---|---|---|
| Invoices in dispute | 18% | 12 to 13% |
| Invoice processing time | 12 days | 4 days |
| Time to onboard a new item | 10 days | 3 days |
| Stock-outs from unconfirmed orders | 6% of lines | 2 to 3% |
| Supplier "where is my payment?" calls | 600 a month | 150 a month |
| Average supplier payment time | 75 days | 50 to 60 days |
Paying faster is not generosity: a supplier paid sooner accepts better commercial terms, often 1 to 2 extra discount points.
Constraints specific to the Senegalese market
The portal must run on a 1 Mbit/s 3G connection: light pages (under 300 KB), forms that save offline, SMS confirmations. Personal data of individual suppliers falls under Law 2008-12 and requires a declaration to the CDP. Also plan the link with the DGID standardized invoice if your ERP already issues it, and hosting with a continuity plan (replication in a second zone, local power cuts included).
Mini case study
Mamadou, purchasing director of a chain of 25 supermarkets in Dakar and Thiès, processes 9,000 supplier invoices a month, 18% of them disputed. Each dispute takes about 45 minutes of accountant and buyer time. Dropping to 12.6% disputes removes 486 disputes a month, or 365 hours saved. At a loaded cost of 4,000 FCFA per hour, the direct gain is 1.46 million FCFA a month, about 17.5 million FCFA a year, plus 1 discount point negotiated on 2 billion FCFA of annual purchases run through the portal, i.e. 20 million FCFA. For a 32 million FCFA project, payback comes in under a year.
