The verdict in three sentences
A cooperative of 2,300 farmers growing groundnuts and mangoes, whether around Accra or Thiès, can deploy an offline collection app for USD 12,000 to 25,000 excl. VAT (7 to 15 million FCFA), including weighing, advances and export traceability. The first visible gain is an 80% drop in weighing disputes, because every weighing is photographed, time-stamped and sent to the farmer by SMS. The second is financial: farmers are paid in 3 days instead of 3 weeks, which keeps their deliveries away from informal buyers.
Detailed budget for a collection app
Harvest season leaves no room for improvisation: thousands of weighings in a few weeks, often in villages without network. The software must keep up. 2026 order of magnitude for a cooperative of this size:
| Module | Scope | Budget excl. VAT (USD) | Timeline |
|---|---|---|---|
| Farmer registry | Profiles, GPS plots, photos, ID documents | 1,700 to 3,300 | 2 to 3 weeks |
| Offline collection and weighing | Smartphone capture, Bluetooth scale, SMS receipt | 3,300 to 6,700 | 4 to 6 weeks |
| Advances and inputs | Pre-harvest advances, seeds, fertiliser, deductions | 1,700 to 4,200 | 3 weeks |
| Farmer payments | Bulk MTN MoMo, Wave or Orange Money transfers | 1,700 to 4,200 | 2 to 3 weeks |
| Export traceability | Lots, warehouses, certificates, EU buyer requirements | 2,500 to 5,000 | 3 to 4 weeks |
| Dashboard | Volumes by village, quality, cash position | 800 to 1,700 | 1 to 2 weeks |
| Total | Full scope | 12,000 to 25,000 | 3 to 5 months |
Also budget for hardware: a rugged smartphone at around USD 200 per collection point and, if needed, a connected scale at USD 250 to 500. Annual maintenance is 10 to 15% of the project.
Paper ledger, spreadsheet or app: what changes
| Criterion | Paper ledger | Shared spreadsheet | Custom app |
|---|---|---|---|
| Weighing disputes per season | 150 to 250 | 80 to 120 | 30 to 50 |
| Farmer payment delay | 3 weeks | 2 weeks | 3 days |
| Works without network | Yes | No | Yes, deferred sync |
| Automatic advance calculation | No | Partial | Yes |
| Lot traceability for export | Impossible | Fragile | Complete |
| Season closing time | 4 weeks | 2 weeks | 3 days |
| Upfront cost | Almost zero | Almost zero | USD 12,000 to 25,000 |
Spreadsheets fail mainly in the field: without network, agents copy data in the evening and errors pile up. The app stores everything locally and syncs when back in coverage.
Mobile payment and traceability: the two commercial levers
Bulk mobile money payment removes trips with bags of cash. Fees stay low, around 1% for transfers, and each farmer receives a detailed statement: weight, price per kilo, advance deducted. For mangoes bound for Europe, buyers increasingly ask for proof of origin by plot. A traceable lot often sells for 5 to 10% more than an anonymous one, which alone funds a large share of the tool.
Mini case study
Kwame, chairman of a cooperative near Accra, collects 3,200 tonnes of groundnuts per season. Weighing disputes cost on average 0.5% of volume in goodwill gestures, i.e. 16 tonnes at USD 0.50 per kilo: USD 8,000. An 80% reduction saves USD 6,400. Add a 5% premium on 400 tonnes of export mangoes sold at USD 0.42 per kilo, i.e. USD 8,400. A USD 18,000 project pays back in just over one season.

FAQ
Do collectors need strong literacy to use the app?
No, the interface relies on icons, photos and little text. Half a day of training is enough for most of a cooperative's 40 to 60 collectors.
What if a phone breaks mid-season?
Data syncs every time the device is in coverage. At worst, only that day's weighings need re-entering from receipts.
Can we pay farmers without a mobile money account?
Yes, the software supports a mixed mode: mobile money for 80 to 90% of farmers and a signed cash payment sheet for the rest.
Does the tool help with organic or fair trade certification?
It provides plot registries, volumes per farmer and lot history, which halves audit preparation time.
How much does hosting cost?
Between USD 40 and 125 per month depending on photo volume and number of users.
