The verdict in three sentences
The Senegalese fish wholesaler operates in a world of cash, prices that shift with every landing and sanitary paperwork for export. A vertical platform digitizes the auction, pays fishermen via mobile money and traces the cold chain through to the EU sanitary certificate. The result: a better-secured margin, reassured export buyers and fewer cold-chain losses.
Prices, margin and volatility: the orders of magnitude
The price per kilo varies sharply by species and daily abundance. The wholesaler buys at landing and resells with a margin covering transport, ice and risk. Here is the 2026 order of magnitude.
| Species | Landing buy price | Resale price | Indicative gross margin |
|---|---|---|---|
| Thiof (grouper) | 3,000 - 5,000 FCFA/kg | 4,500 - 7,000 FCFA/kg | 25 - 40 % |
| Sardinella | 400 - 800 FCFA/kg | 600 - 1,200 FCFA/kg | 30 - 50 % |
| Export shrimp | 4,000 - 7,000 FCFA/kg | 6,000 - 10,000 FCFA/kg | 30 - 45 % |
| Export octopus | 2,500 - 4,500 FCFA/kg | 4,000 - 6,500 FCFA/kg | 30 - 45 % |
| Sea bream | 1,500 - 2,500 FCFA/kg | 2,200 - 3,800 FCFA/kg | 25 - 40 % |
Volatility is the enemy of margin: a digital auction that shows real-time prices and logs transactions helps the wholesaler buy at the right moment.
Functions along each link of the chain
A wholesaler platform is only useful if it covers every link, from landing to export buyer. Here is the breakdown of functions.
| Link | Platform function | Benefit |
|---|---|---|
| Fisherman | Instant mobile money payment | End of cash, loyalty |
| Auction | Real-time bids/prices | Optimized buying, transparency |
| Storage | Cold-chain temperature tracking | Fewer losses |
| Lots | Origin traceability + timestamp | Sanitary compliance |
| Export | EU sanitary certificate generation | European market access |
| Buyer | Order tracking + invoice | Trust, loyalty |
| Management | Margin and volume dashboard | Fast decisions |
End-to-end traceability is the condition for accessing demanding export markets, where an untraced lot is simply rejected.
Mini case study
Modou is a wholesaler at the Dakar port handling 2,000 kg of octopus a week, bought at 3,500 FCFA/kg and resold for export at 5,500 FCFA/kg, i.e. a 4,000,000 FCFA weekly gross margin. Before the platform, he lost about 8 % of stock on the cold chain and missed export sales for lack of timely certificates. With temperature tracking and automatic certificate generation, his losses drop to 3 %, i.e. 100,000 FCFA recovered per week, and he lands two extra European buyers thanks to proven traceability.

FAQ
Why pay fishermen via mobile money?
It eliminates cash, secures transactions and builds loyalty as fishermen are paid instantly. The wholesaler keeps a precise history to steer purchasing.
Is traceability mandatory to export to the EU?
Yes, European markets require traceability and sanitary certificates. An untraced lot is rejected: the platform generates these documents automatically and secures market access.
How does the digital auction optimize margin?
By showing real-time prices and per-species history, the wholesaler buys at the best moment. On volatile products like shrimp, this protects a 30 to 45 % margin.
How much does such a platform cost?
A wholesaler vertical platform with traceability and payments ranges from 3,000,000 to 7,000,000 FCFA depending on modules. It is an advanced e-commerce investment backed by real margin gains.
Does it work on weak connections at the port?
Yes, it is mobile-optimized and runs on 3G with caching. Data syncs as soon as the connection returns.
