The verdict in three sentences
Dispatching your technicians by phone and WhatsApp costs you wasted trips, jobs with no proof, and invoices that drag on. A field service app centralizes work orders, scheduling, an on-site signed job report and invoicing, moving a technician from 4 to 6 jobs per day and the invoicing delay from 15 to 2 days. Custom-built (2,000,000 to 5,000,000 FCFA) or SaaS (25,000 to 70,000 FCFA/month per technician): the choice depends on your headcount and business rules.
What a dispatch app changes
The core problem isn't lack of work, it's the time lost between jobs and the lack of proof when a client disputes. A signed report with photos removes disputes and unlocks same-day Mobile Money collection.
| Metric | Without app (2026) | With field service app |
|---|---|---|
| Jobs / technician / day | 4 | 6 |
| Average invoicing delay | 15 days | 2 days |
| First-time fix rate | 62% | 84% |
| Optimized travel (km/day) | 90 km | 60 km |
| Job disputes | 9% | 2% |
| Reports signed on site | 0% | 95% |
One hour saved per technician per day is one extra billable job: across 6 technicians, the app pays for itself within months.
Custom or SaaS: the real math
| Criterion | Custom app | Field service SaaS |
|---|---|---|
| Upfront cost | 2,000,000 - 5,000,000 FCFA | 0 - 150,000 FCFA (setup) |
| Monthly cost | Hosting 15,000 - 40,000 FCFA | 25,000 - 70,000 FCFA / technician |
| Year 1 cost (6 technicians) | ~3,500,000 FCFA | ~2,700,000 - 5,000,000 FCFA |
| Specific business rules | Fully custom | Limited to standard |
| Built-in Mobile Money invoicing | Yes, native | Often via external module |
| Data ownership | You | Vendor |
From 5-6 technicians and with your own business rules (contracts, SLAs, zone pricing), custom becomes more cost-effective over 2 years and keeps you the owner of your data.
Mini case study
Mamadou runs a refrigeration company in Accra with 6 technicians. Before: 4 jobs/day, invoice sent 15 days later. At 45,000 FCFA per average job, moving to 6 jobs/day adds 2 x 6 = 12 jobs/day, i.e. 540,000 FCFA/day of potential extra revenue. Even converting only half, he gains ~270,000 FCFA/day. The app at 3,500,000 FCFA pays back in under three weeks of net gain.

FAQ
How much does a custom field service app cost in 2026?
Budget 2,000,000 to 5,000,000 FCFA depending on modules (scheduling, parts stock, invoicing, client portal). Hosting runs 15,000 to 40,000 FCFA/month, with no per-technician fee.
Does the app work offline in the field?
Yes. Offline mode stores the report, photos and signature locally, then syncs once the network returns. Essential in areas where 4G is patchy outside main roads.
How does the signed report speed up collection?
The client signs on the phone at the end of the job, the report generates the invoice, and Mobile Money payment (MTN, etc.) is offered instantly. The average delay drops from 15 days to 2 days.
Can routes be optimized automatically?
Yes, the app groups jobs by zone and proposes the shortest order, cutting travel from ~90 to ~60 km/day and freeing up billable time.
What if I only have 2 technicians?
At small scale, a SaaS at 25,000 FCFA/month/technician can be enough to start. Custom becomes worthwhile from 5-6 technicians or when you have specific business rules.
