The verdict in three sentences
A harvest management app turns a paper ledger into precise tracking of yield per plot and post-harvest stock, which alone cuts losses from 20 % to about 9 % on a 40-hectare farm. The choice comes down to two options: an agri SaaS at 9,000 FCFA/month to start fast, or a custom app at 450,000 FCFA paid back in under two seasons once needs get specific. In both cases the real differentiator in the region is offline 3G mode: without it, no reliable field data entry.
What a modern harvest app tracks
The core is not accounting, it is plot-by-plot traceability. Each entry links a harvested quantity to a plot, a date and an input cost, making the real margin of every hectare visible. Here are the functions that matter in 2026 and their measured impact.
| Agri-tech function | What it measures | 2026 impact (order of magnitude) |
|---|---|---|
| Yield per plot | Tonnes/ha per zone | Gaps of 15 to 30 % detected between plots |
| Post-harvest stock | Silo in/out | Losses 20 % -> 9 % |
| Input cost per ha | Seed, fertilizer, labour | Net margin visible per plot |
| Real-time market price | Daily price entered | +8 to 12 % on sale price |
| Harvest forecasts | Pre-cut projection | Logistics planning at D-30 |
| Offline 3G mode | Entry without network | 100 % of data captured |
| Lot traceability | Origin per bag | Access to premium markets |
The difference between a farm that steers and one that endures lies in these seven lines. Cutting post-harvest losses by 11 points on 40 hectares means dozens of tonnes saved each season.
Custom build or agri SaaS: the real math
The SaaS at 9,000 FCFA/month costs 108,000 FCFA a year with no upfront investment. The custom app at 450,000 FCFA is an asset you own, adaptable to your crops and silos. Over three years the math flips quickly.
| Criterion | Agri SaaS (9,000 FCFA/mo) | Custom app (450,000 FCFA) |
|---|---|---|
| Year 1 cost | 108,000 FCFA | 450,000 FCFA |
| 3-year cost | 324,000 FCFA | 450,000 FCFA + hosting |
| Crop customization | Limited to templates | Total |
| Offline mode | Vendor-dependent | Guaranteed in spec |
| Data ownership | With the vendor | With you |
| Evolution | Vendor roadmap | On demand |
| Time to launch | 1 day | 3 to 5 weeks |
SaaS wins when you want to test fast and stay small. Custom wins once lot traceability opens premium markets that justify the investment.
Mini case study
Amadou farms 40 hectares of maize and millet near Kampala. Before the app, he estimated post-harvest losses at 20 %, about 24 tonnes lost out of 120 harvested. At an average 180 FCFA/kg, that was 4,320,000 FCFA gone each season. By cutting losses to 9 % through stock tracking and moisture alerts, he now loses only 10.8 tonnes, or 1,944,000 FCFA. Net gain: 2,376,000 FCFA per season. His 450,000 FCFA custom app pays for itself in a single harvest, margin included.

FAQ
How much does a harvest management app cost in 2026?
Budget around 450,000 FCFA for a custom offline app, or 9,000 FCFA/month for an agri SaaS. Custom becomes cheaper from the second year of intensive use.
Is offline mode really essential?
Yes. In rural areas 3G is intermittent: without offline entry, up to 40 % of field data never syncs. A well-built app syncs as soon as the network returns.
Can I track yield plot by plot?
That is the heart of the system. Gaps of 15 to 30 % between neighbouring plots are common, guiding input decisions and sometimes doubling a zone's margin.
How long does deployment take?
A SaaS launches in a day. A custom app takes 3 to 5 weeks, including spec and seasonal-worker training.
What return on investment can I expect?
On a 40-hectare farm, cutting losses from 20 % to 9 % often means over 2,000,000 FCFA per season, paying back the custom app in the first harvest.
