The verdict in three sentences
For an agribusiness headquartered in London that runs an outgrower programme of 6,000 smallholders in West Africa, offline field software used by 40 extension officers costs 60,000 to 150,000 GBP and typically pays back within the first season. The main lever is simple: link every bag of fertiliser issued to a named farmer, then deduct it automatically from the crop payment. Cutting input loan defaults from 12% to 4% is worth hundreds of thousands of pounds a year.
What the solution costs in 2026
The head of sourcing at a London agribusiness usually inherits a patchwork: paper ledgers in the field, spreadsheets shared by WhatsApp, hand-written weights. Leaks come from duplicates, forgotten deductions and farmers served twice. Here are 2026 market ranges.
| Item | Indicative budget | Comment |
|---|---|---|
| Offline mobile app and back office | 60,000 to 150,000 GBP | Depends on modules and integrations |
| Rugged tablets for 40 officers | 6,000 to 10,000 GBP | 150 to 250 GBP each |
| Connected scales (optional) | 400 to 900 GBP per buying point | Weight captured without re-keying |
| Cloud hosting | 300 to 1,000 GBP per month | Daily backups, audit logs |
| Officer training | 5,000 to 12,000 GBP | 2 days per zone |
| Time to go live | 4 to 6 months | Ideally before input distribution |
For schemes supplying European buyers, the same data also supports EUDR and sustainability reporting (farm GPS, volumes per farmer), which often justifies the upper end of the budget.
The modules that cut defaults
Each module fixes a specific leak observed in West African cotton and cocoa outgrower schemes.
| Module | Leak fixed | Target metric |
|---|---|---|
| Farmer registry with photo and farm GPS | Ghost farmers, duplicates | 0 duplicates |
| Input distribution signed on tablet | Unassigned bags | 100% of bags linked |
| Credit calculation and ceiling per hectare | Over-indebtedness | Ceiling respected 100% |
| Weighing and collection records | Data entry errors | Weighing variance under 0.5% |
| Automatic loan deduction from payment | Forgotten deductions | Defaults from 12% to 4% |
| Traceable farmer payments (mobile money or cash) | Disputes over amounts | SMS receipt for every payment |
| Dashboard per farmer group | Flying blind | Real-time season status |
Offline mode is non-negotiable: in remote areas, the officer records distribution and weighing without signal, and everything syncs back in a covered zone.
Mini case study
Typical scenario: James, head of sourcing at a London agribusiness, oversees a scheme of 6,000 smallholders in Burkina Faso. Each receives on average 150,000 FCFA (about 200 GBP) of inputs on credit, i.e. roughly 1.2 million GBP advanced per season. At 12% defaults, the loss reaches 144,000 GBP.
At 4%, it drops to 48,000 GBP: 96,000 GBP preserved per season. Even assuming only half that effect (48,000 GBP), a total investment of 110,000 GBP (app at 90,000 GBP, tablets at 8,000 GBP, training at 12,000 GBP) pays back within about two seasons, and within one at full effect. With 25,000 tonnes collected, weighing traceability also secures farmer payments and buyer audits. These figures are illustrative orders of magnitude.

FAQ
Does the app work without network coverage?
Yes, every field operation is stored on the tablet and synced as soon as 2G, 3G or 4G is available. A tablet easily holds several thousand transactions.
Can farmers be paid by mobile money?
Yes, integration with Orange Money or Moov Money is possible through operator APIs. It usually adds 1,500 to 3,000 GBP to the budget and reduces cash handling.
What about farmers without a phone?
They are identified by a farmer card with a QR code and photo. Receipts can be printed on a Bluetooth printer costing around 90 GBP.
Can officers unused to tablets handle it?
Yes, the interface uses large icons with 5 to 6 screens maximum per operation. Two days of training per zone is usually enough.
When should the project start?
Ideally 6 months before input distribution, to pilot with 2 farmer groups during the previous season. A late start is still possible by limiting the pilot to collection.
