The verdict in three sentences
An unanticipated stock-out costs 5 to 12 % of revenue in lost sales and disappointed customers, and a simple alert threshold prevents it. Setting a WhatsApp or email notification as soon as a product drops below 5 units lets you restock in time and automatically hide sold-out products. The setup costs 100,000 to 300,000 FCFA in 2026 and pays for itself on the first avoided stock-out of a bestseller.
What an alert system really prevents
Without alerts, you discover the stock-out when a customer complains or an order can't be fulfilled. Here is the 2026 order of magnitude of avoided losses.
| Situation | Without alert | With threshold alert |
|---|---|---|
| Bestseller stock-outs / month | 3 to 5 | 0 to 1 |
| Revenue lost per bestseller stock-out | 40,000 to 80,000 FCFA | avoided |
| Undeliverable orders taken | 4 to 6/month | 0 (auto-hide) |
| Mobile money refund fees | 1.5 % / order | near zero |
| Average restock delay | 6 days | 2 days |
Automatically hiding a zero-stock product removes the worst scenario: taking a Wave payment for an item you can't deliver.
Configuring your alerts in 2026
A good system combines a configurable threshold, a notification channel and restock triggering. Here are the tiers and their estimated costs.
| Tier | Functions | Setup cost | Maintenance/month |
|---|---|---|---|
| Basic | Fixed threshold + email | 100,000 FCFA | 15,000 FCFA |
| Standard | Per-product threshold + WhatsApp + auto-hide | 200,000 FCFA | 30,000 FCFA |
| Advanced | + restock forecasting + SMS + dashboard | 300,000 FCFA | 45,000 FCFA |
| Custom | + automatic supplier purchase order | 500,000 FCFA+ | 65,000 FCFA |
The threshold must account for supplier lead time: if restocking takes 5 days and you sell 2 units/day, set the alert at 10 units, not 5.
Mini case study
Moussa runs an electronics store in Dakar with a bestseller sold at 25,000 FCFA, 60 sales/month. He suffered 4 stock-outs/month of that product, each costing about 3 days of lost sales, i.e. 6 units × 25,000 = 150,000 FCFA/month. He installs Standard alerts at 200,000 FCFA (maintenance 30,000 FCFA/month), threshold set at 10 units. Stock-outs fall below one per month: he recovers about 120,000 FCFA/month. Net of maintenance: 90,000 FCFA/month, system paid back in just over 2 months.

FAQ
What threshold should I set for the stock alert?
The level that covers your restock delay. Simple formula: daily sales × supplier lead time in days, plus a safety margin. For 2 sales/day and 5 days' delay, set it at 10-12 units.
Is automatic hiding really useful?
Yes. It prevents taking an undeliverable order, avoiding the refund, the negative review and the loss of trust. It's the most profitable function of the setup.
Which notification channel should I choose?
WhatsApp is most effective in Anglophone Africa because it's read immediately. Email serves as archive and SMS as backup when data connectivity is missing.
How much do stock alerts cost in 2026?
From 100,000 FCFA for a basic email version to 300,000 FCFA for an advanced version with forecasting and SMS, plus 15,000 to 45,000 FCFA in monthly maintenance.
Can I automate the supplier purchase order?
Yes, at the custom tier. As soon as the threshold is hit, the system generates a pre-filled purchase order to send to the supplier, further shortening the restock delay.
