The verdict in three sentences
In Saint-Louis, an online shop doing 2,000,000 FCFA in monthly sales (about 3,050 EUR) can easily lose money if it ignores acquisition cost, delivery fees and returns. Managing by net margin per order is the skill that separates sellers who grow from those who burn out. A 40-hour course at 200,000 FCFA pays off as soon as it adds 2 to 3 margin points.
The real maths of an order in Saint-Louis
Take an average basket of 15,000 FCFA, typical for ready-to-wear, cosmetics or accessories sold via Instagram, Facebook and WhatsApp across Sor, the island and Ndar Toute.
| Cost per order | 2026 order of magnitude | % of a 15,000 FCFA basket |
|---|---|---|
| Cost of goods | 6,750 FCFA | 45% |
| Meta customer acquisition cost (1,500 to 5,000 FCFA) | 3,000 FCFA | 20% |
| Delivery (1,000 to 2,500 FCFA per parcel) | 1,500 FCFA | 10% |
| Wave or Orange Money fees (about 1%) | 150 FCFA | 1% |
| Cost of returns (5 to 12% of orders) | 750 FCFA | 5% |
| Packaging and small costs | 400 FCFA | 2.7% |
| Net margin before fixed costs | 2,450 FCFA | 16.3% |
On 150 orders a month (2,250,000 FCFA in sales), the margin before fixed costs is about 367,500 FCFA. Subtract an assistant at 100,000 FCFA, internet and storage, and little remains. A CAC rising from 3,000 to 5,000 FCFA pushes the margin down to 3%.
The levers that move the margin
| Lever | Concrete action | Estimated gain per order |
|---|---|---|
| Lower CAC | Retargeting, lookalike audiences, organic content | 500 to 1,500 FCFA |
| Raise average basket | Bundles, free delivery from 25,000 FCFA | 1,000 to 3,000 FCFA extra margin |
| Bring customers back | WhatsApp list, repurchase offers at D+30 | CAC near 0 on the 2nd order |
| Limit returns | Size guide, phone confirmation before shipping | 300 to 600 FCFA |
| Negotiate delivery | Volume deal with a courier, grouped rounds | 200 to 500 FCFA |
| Deposit at order | 30% by Wave before shipping | Fewer refusals at delivery |
None of these levers is spectacular alone. Combined, they can lift net margin from 10 to 20%, doubling profit without selling a single extra order.

Mini case study
Learn this skill with Kolonell Academy
Short, practical online courses (taught in French), graded exercises, certificate. Pay with Wave or Orange Money.
Fatou, 31, runs an online ready-to-wear shop in Saint-Louis: 2,800,000 FCFA in sales a month, 180 orders, average CAC of 4,200 FCFA and 10% returns. Her net margin before fixed costs is around 8%, about 224,000 FCFA.
After setting up a WhatsApp repurchase list and a 25,000 FCFA bundle, her average CAC drops to 3,000 FCFA (gain of 1,200 FCFA × 180 = 216,000 FCFA) and returns fall to 6% thanks to phone confirmation (gain of about 100,000 FCFA). Estimated monthly margin: about 540,000 FCFA (about 820 EUR), i.e. +316,000 FCFA. The 200,000 FCFA course is covered in under a month. These figures are an illustration; your results will depend on your product and execution.
FAQ
From what revenue is this level useful?
From 1,000,000 FCFA in monthly sales, management pays off. Below that, levels 1 to 3 of the track, starting at 25,000 FCFA, are a better fit.
What CAC should I target on Meta in 2026?
As a rough guide, 1,500 to 3,000 FCFA for a 15,000 FCFA basket remains healthy. Above 20% of the basket, profitability becomes fragile.
Does the course cover team management?
Yes, one module covers hiring an assistant or courier, pay (often 75,000 to 150,000 FCFA a month in Saint-Louis) and the indicators to track weekly.
How long does it take to finish?
The 40 hours fit into 8 weeks at 5 hours a week. You apply the margin tables directly to your own sales.
