The verdict in three sentences
A fresh-produce distributor that does not monitor its cold chain loses 15 to 30 % of goods to breaks detected too late. An IoT-monitoring SaaS (sensors + subscription 45,000-120,000 FCFA/month) alerts in real time; a custom application (build 5,000,000-9,000,000 FCFA) integrates your sensors, HACCP register and proof of compliance for your retail clients. Loss falls to 3-6 %, paying back the investment very fast.
Monitoring SaaS or custom app: the comparison
IoT SaaS is quick to deploy and covers basic alerting. Once you must prove HACCP compliance to large retailers and cross-reference temperature, geolocation and batches, the dedicated app takes over.
| Criterion | IoT-monitoring SaaS | Custom application |
|---|---|---|
| Upfront cost | Sensors (variable) | 5,000,000 - 9,000,000 FCFA |
| Monthly cost | 45,000 - 120,000 FCFA | 70,000 - 130,000 FCFA (maintenance) |
| 3-year cost | 1,620,000 - 4,320,000 FCFA | 7,520,000 - 13,680,000 FCFA |
| Real-time temperature alert | Standard | Tailored by threshold |
| HACCP register | Generic | Digital and adapted |
| Refrigerated-truck geolocation | Plan-dependent | Native |
| Retail compliance proof | Limited | Exportable reports |
The loss numbers
The core of the calculation is goods saved. Here is the typical impact for a distributor in 2026 (order of magnitude).
| Indicator | Without monitoring | With the app |
|---|---|---|
| Goods loss | 15 - 30 % | 3 - 6 % |
| Cold-break detection | after the fact | real time |
| Temperature register | paper, incomplete | digital, timestamped |
| Product recalls | high risk | avoided by traceability |
| Refrigerated-truck tracking | none | geolocated |
| Cost of a quality officer | 220,000 FCFA/month | better leveraged |
Mini case study
Neema runs a fresh-produce distributor in Dar es Salaam with a monthly goods volume of 20,000,000 FCFA. At 20 % loss on the cold chain, she destroys about 4,000,000 FCFA/month of stock. By cutting loss to 5 % through real-time alerts, loss drops to 1,000,000 FCFA/month, saving 3,000,000 FCFA per month. An app at 7,000,000 FCFA plus sensors pays back in about 3 months, before counting the value of retail contracts secured by proof of compliance.

What is the difference between IoT SaaS and the custom app?
SaaS alerts when a sensor crosses a threshold. The custom app cross-references temperature, batches, geolocation and the HACCP register to produce exportable proof of compliance, essential for large retail clients in 2026.
How does the alert cut loss to 3-6 %?
As soon as a fridge drifts, the officer gets an alert and acts before the goods are lost. Real-time detection replaces after-the-fact discovery.
Is a digital HACCP register accepted in inspections?
Yes: each reading is timestamped and archived, providing a reliable history in audits, whereas a paper register is often incomplete.
Can refrigerated trucks be tracked?
Yes, geolocation shows the position and temperature of trucks on route, allowing you to anticipate an incident on a long trip.
How long to deploy?
An MVP (sensors, alerts, HACCP register) ships in 6 to 10 weeks depending on the number of sites and vehicles to equip.
