The verdict in three sentences
For a project collecting data in 50 to 500 villages in Burkina Faso or elsewhere in West Africa, KoboToolbox and ODK remain the best starting point as long as you run one-off surveys with stable forms. A custom offline-first web app with deferred synchronisation and monitoring dashboards costs 8 to 25 million FCFA (about 12,200 to 38,100 EUR) and ships in 12 to 16 weeks in 2026. It becomes the right choice once you track the same beneficiaries, plots or water points over time, with several validation levels and indicators your donors expect.
Field conditions set the constraints
Between Ouagadougou, the Centre-Nord provinces and rural areas of the Boucle du Mouhoun, 4G coverage is patchy and power cuts are frequent. An enumerator can spend 3 to 7 days without usable network. The tool must save locally, compress photos, geolocate offline and sync within minutes as soon as one bar of signal appears, without losing a single form.
Paper costs more than people think: printing, shipping notebooks back to the capital, data entry clerks, transcription errors (5 to 12% of forms on average) and 4 to 8 weeks before the first analysis.
KoboToolbox, ODK or custom: the 2026 comparison
| Criterion | KoboToolbox | Self-hosted ODK Central | Custom app |
|---|---|---|---|
| Licence cost | Free for humanitarian actors (quotas) | Free, hosting 15,000 to 60,000 FCFA per month | Included in the project |
| Setup cost | 0 to 1.5 M FCFA of configuration | 1 to 3 M FCFA | 8 to 25 M FCFA |
| Offline mode | Yes, form by form | Yes | Yes, with reference data and history |
| Longitudinal tracking (same beneficiaries) | Limited | Limited, via entities | Native |
| Multi-level validation | Basic | Basic | Supervisor, coordinator, head office |
| Donor dashboards | Export to Excel or Power BI | Export | Built in, real time |
| Implementation time | 1 to 3 weeks | 3 to 6 weeks | 12 to 16 weeks |
Custom development does not replace Kobo for a one-off baseline survey. It takes over for 2 to 5 year programmes where data drives daily management and quarterly reporting.
What drives the budget
| Component | 2026 range (FCFA) |
|---|---|
| Scoping, data model, mock-ups | 1,000,000 to 2,500,000 |
| Offline app (PWA), dynamic forms, GPS, photos | 3,000,000 to 8,000,000 |
| Deferred sync and conflict handling | 1,500,000 to 4,000,000 |
| Multi-level validation and roles | 800,000 to 2,500,000 |
| Dashboards and donor exports | 1,200,000 to 4,500,000 |
| Training for enumerators and supervisors | 500,000 to 1,500,000 |
| Annual hosting and maintenance | 1,200,000 to 3,600,000 |
A PWA runs on entry-level Android smartphones (40,000 to 70,000 FCFA each), so there is no need to buy tablets. Donors often require documented hosting and a data protection policy compliant with Burkina Faso's law no. 001-2021: plan it from scoping.
Mini case study
Issouf, project manager at a consultancy in Ouagadougou, follows 6,000 households in 180 villages for a food security programme, with 4 rounds a year, or 24,000 forms. On paper, each form costs about 2,400 FCFA (printing, transport, data entry, corrections), 57.6 million FCFA a year. He invests 16 million FCFA in an offline app and 2.4 million a year in maintenance. Cost per form drops to about 800 FCFA (amortised smartphones, data bundles, supervision), 19.2 million a year. First-year saving: 57.6 - 19.2 - 16 - 2.4 = 20 million FCFA (about 30,500 EUR), and quarterly reports come out in 3 days instead of 5 weeks.

FAQ
How long can a phone stay offline?
As long as needed: a well-built PWA stores several thousand forms and compressed photos. We usually test 15 days without network before going live.
What if two enumerators edit the same record?
Sync detects the conflict and the supervisor resolves it from the dashboard. This affects under 1% of records when areas are well allocated.
Can we migrate our KoboToolbox data?
Yes, Kobo exports are migrated in 1 to 2 weeks. Your XLSForm files also serve as a scoping base, which cuts cost by 10 to 15%.
Is the data secure?
Encryption on the phone and in transit, role-based access, change log. Hosting can be on a cloud provider or on the organisation's own server.
Can the budget go into a funding proposal?
Yes, we provide a quote broken down by lot (development, training, maintenance) compatible with major donor formats, with a maintenance line for the programme's duration.
