The verdict in three sentences
A subscription box smooths revenue and makes it predictable: 200 subscribers at 20,000 FCFA/month = 4M FCFA of MRR. The make-or-break metric is churn: at 6 %/month a subscriber stays 16 months on average, giving a 320,000 FCFA LTV. The major technical blocker remains recurring mobile money billing: without an automatic mandate, you chase payment by hand every month and churn explodes.
The box economic model
A box lives and dies on three numbers: price, margin per box and churn. Set the price between 15,000 and 30,000 FCFA depending on perceived value and contents.
| Line item | Entry box (15,000) | Premium box (30,000) |
|---|---|---|
| Subscriber price/month | 15,000 FCFA | 30,000 FCFA |
| Product cost | 6,000 FCFA | 12,000 FCFA |
| Packaging + shipping | 2,500 FCFA | 3,500 FCFA |
| Payment fees (~2 %) | 300 FCFA | 600 FCFA |
| Gross margin/box | 6,200 FCFA | 13,900 FCFA |
| Margin % | 41 % | 46 % |
MRR, churn and the LTV/CAC ratio
At 200 subscribers the model becomes a recurring-revenue machine. The key is keeping CAC (acquisition cost) well below LTV.
| Metric | Conservative scenario | Target scenario |
|---|---|---|
| Subscribers | 200 | 200 |
| Average price/month | 20,000 FCFA | 20,000 FCFA |
| MRR | 4,000,000 FCFA | 4,000,000 FCFA |
| Monthly churn | 8 % | 5 % |
| Average lifetime | 12.5 months | 20 months |
| LTV (margin x lifetime) | 100,000 FCFA | 160,000 FCFA |
| CAC | 35,000 FCFA | 35,000 FCFA |
| LTV/CAC ratio | 2.9 | 4.6 |
An LTV/CAC ratio above 3 is healthy; above 4, you can safely accelerate acquisition.

Mini case study
Ibrahim launches a coffee-and-spice box in Nairobi, priced 20,000 FCFA/month, gross margin 8,000 FCFA/box. He reaches 200 subscribers in 8 months at a 35,000 FCFA CAC. Churn starts at 9 % (manual reminders), then drops to 5 % after switching to a recurring mobile money mandate. Lifetime rises from 11 to 20 months: LTV climbs from 88,000 to 160,000 FCFA per subscriber. Across his base of 200, that is 14.4M FCFA of future value created by the switch to automatic billing alone.
FAQ
How should I price a box? Between 15,000 and 30,000 FCFA/month depending on contents and perceived value. Aim for at least 40 % gross margin after products, packaging and shipping; below that, normal churn makes the model unprofitable.
How do I handle recurring mobile money billing? Use a recurring mandate with Wave or Orange Money where available, otherwise an automated WhatsApp payment reminder 3 days before renewal. Automatic billing cuts churn by 3-4 points.
What churn should I target? 5-8 %/month is the norm for a consumer box. Every point of churn removed adds several months of lifetime and thus LTV; work on surprise, delivery reliability and contents.
How many subscribers to live off the box? At 8,000 FCFA margin/box, 200 subscribers generate 1.6M FCFA gross margin monthly. Deduct fixed logistics and acquisition: count on 250-300 subscribers for a comfortable net founder income.
Should I offer 3/6/12-month commitments? Yes: a prepaid 3-month commitment cuts churn and improves cash flow. Offer a free box or -15 % on the annual plan to push long-term subscriptions.
