The verdict in three sentences
A custom field service management web app is priced between 20,000 and 60,000 EUR excl. VAT in 2026, depending on technician count and modules. The benchmark gain is +30 % jobs handled per day thanks to fewer trips, less re-keying and fewer back-and-forths to the office. For a team of 8 to 25 technicians, the tool pays for itself in 6 to 12 months.
The functional building blocks of a field service tool
The typical cycle: a customer reports a fault, a ticket is created, a technician is assigned by location and skill, they carry out the job, get the customer's signature and trigger invoicing. Every step lost to phone calls or paper costs hours.
| Function | What it delivers | 2026 range (EUR excl. VAT) |
|---|---|---|
| Ticket management | Creation, prioritization, SLA | 4,000 - 8,000 |
| Technician scheduling | Assignment by skill/zone | 5,000 - 10,000 |
| Technician mobile app | Work order, photos, signature | 6,000 - 13,000 |
| Spare-parts stock | Tracking, reservation, alert thresholds | 4,000 - 9,000 |
| Customer signature | Electronic service report | 2,000 - 4,500 |
| Invoicing / quotes | Auto-generated post-job | 3,500 - 7,500 |
| Customer portal | Ticket tracking, history | 3,000 - 7,000 |
Typical quote by team size
The timeline is 4 to 6 months for a full V1. The number-one price driver is the number of mobile technicians and scheduling complexity (skills, zones, maintenance contracts).
| Profile | Technicians | Scope | 2026 quote (EUR excl. VAT) | Timeline |
|---|---|---|---|---|
| Micro service firm | 3-8 | Tickets + mobile app | 20,000 - 30,000 | 4 months |
| Maintenance SME | 8-25 | + stock + invoicing | 35,000 - 48,000 | 5 months |
| Multi-branch network | 25-60 | + customer portal + SLA | 50,000 - 60,000 | 6 months |
Mini case study
Sophie heads field service at an HVAC maintenance SME in Lyon and manages 14 technicians. Each does an average of 4 jobs/day. With a tool that optimizes routes and removes trips back to the office, she targets +30 %, i.e. just over 5 jobs/day per technician.
That means 14 x 1.2 extra jobs x 220 days = about 3,700 additional jobs/year. At an average margin of 60 EUR excl. VAT per job, gross gain approaches 222,000 EUR excl. VAT/year. The app, quoted at 42,000 EUR excl. VAT, is paid back in under 3 months of added capacity.

How is this different from an off-the-shelf field service tool?
Field service SaaS costs 25-65 EUR/technician/month but imposes its own logic. Custom is justified if you have maintenance contracts, specific SLAs or complex parts management: beyond 15 technicians, the price gap amortizes quickly.
Does an electronic signature have legal value?
Yes. A signature on a service report, timestamped and tied to the signer's identity, serves as proof of completion. It significantly cuts invoicing disputes and speeds up payment.
Can the tool connect to our accounting software?
Yes, via API or export. Common integrations (Sage, EBP, Cegid) cost 4,000 to 9,000 EUR excl. VAT depending on depth: invoicing, ledger entries, VAT.
How do we handle technicians with no network?
An offline-capable app stores work orders and reports, then syncs when the signal returns. Essential for jobs in basements, rural areas or industrial sites.
How long to train technicians?
Half a day is enough for the mobile app. Adoption exceeds 85 % within a month if the interface stays minimal: see your route, fill in the report, get the signature.
