The verdict in three sentences
With 25 technicians run from a shared spreadsheet, a manufacturer loses on average 1 to 2 service calls per technician per week to re-keying, phone calls and badly sequenced trips. Market FSM software (Field Service Management) costs 60 to 135 CAD per technician per month (about 40 to 90 EUR), while a custom application is priced at 52,000 to 135,000 CAD (35,000 to 90,000 EUR) for 3 to 5 months of development. Custom becomes worthwhile when your maintenance contracts, spare parts and compliance reports do not fit the standard model.
What the shared spreadsheet costs you today
In after-sales service for commercial kitchen equipment (combi ovens, walk-in coolers, hood dishwashers), one technician covers Montreal, Laval and the South Shore. The spreadsheet knows nothing about technician location, van stock or machine history. The result: return trips for a missing part and paper reports re-typed in the evening.
| Loss item (2026 order of magnitude) | With shared spreadsheet | With dedicated app | Gain per technician |
|---|---|---|---|
| Service calls completed per week | 12 to 14 | 14 to 16 | +1 to +2 |
| Return trips for a missing part | 1.5 per week | 0.5 per week | 1 trip avoided |
| Re-typing reports | 3 h per week | 0 h (report signed on mobile) | 3 h |
| Time to invoice after a call | 8 to 15 days | 1 to 2 days | Faster cash flow |
| Unnecessary kilometres | 120 km per week | 70 km per week | 50 km |
| Disputes over unsigned reports | 4 % of calls | Under 1 % | Fewer credit notes |
Market FSM or custom application
Market FSM tools handle scheduling, the mobile app and signatures well. They struggle with a manufacturer's specifics: manufacturer warranties, serial numbers, parts bills of materials and preventive maintenance contracts with variable frequencies.
| Criterion (2026 market estimate) | Market FSM software | Custom application |
|---|---|---|
| Entry cost | 3,000 to 12,000 CAD setup | 52,000 to 135,000 CAD |
| Recurring cost for 25 technicians | 1,500 to 3,375 CAD/month | 600 to 1,800 CAD/month (hosting + maintenance) |
| Time to go live | 4 to 8 weeks | 3 to 5 months |
| Service report signed on mobile | Yes, standard template | Yes, matching your forms and clients |
| Warranty and serial number tracking | Partial | Native, linked to your ERP |
| Parts stock per van | Paid optional module | Built into scheduling |
| Cumulative 5-year cost | 93,000 to 214,500 CAD | 88,000 to 243,000 CAD |
| Ownership of code and data | No | Yes |
Over 5 years the two options cross. The decision therefore rests on business fit, not on price alone.
Scope of an effective first release
To hold 3 months and a budget near 67,000 CAD, limit the first release to four building blocks:
- Scheduling by zone, skill and urgency, with a map view.
- Offline technician mobile app (restaurant basements without signal), with photos and machine history.
- Signed service report on mobile, emailed to the client as a PDF automatically.
- Export to invoicing in your existing ERP.
Van stock, a client portal and automated preventive maintenance come in release two, for an extra 22,000 to 45,000 CAD.

Julie, after-sales director at a commercial oven manufacturer in Laval, manages 25 technicians. A service call is billed on average 270 CAD, labour and travel included. If the app gains 1 call per technician per week over 45 working weeks, that is 25 x 45 = 1,125 extra calls, or 303,750 CAD of additional revenue. At a 35 % margin per call, the gain is about 106,300 CAD a year. A custom app at 90,000 CAD plus 14,400 CAD of annual maintenance pays for itself in just under 12 months, not counting the 3 hours of re-typing saved per technician each week.
FAQ
How much does a custom field service app cost for 25 technicians?
As a 2026 order of magnitude, plan 52,000 to 135,000 CAD depending on scope. A first release limited to scheduling, mobile and signed reports sits around 60,000 to 75,000 CAD.
How long does it take to go live?
Three to five months, including 2 to 3 weeks of scoping and a 3-week pilot with 3 or 4 technicians before full rollout.
Does the app work without mobile signal?
Yes, if it is designed offline-first: data syncs as soon as the signal returns. Insist on this, because 10 to 20 % of kitchen service calls happen in basements.
Is a report signed on a phone legally valid?
A scanned handwritten signature, time-stamped and attached to the PDF report, is admissible evidence in most commercial disputes. For high-stakes contracts, an advanced e-signature costs 1.50 to 4.50 CAD per document.
Should the app connect to the ERP from day one?
An export to invoicing is enough for release one. Full sync of items and customers adds 7,500 to 22,000 CAD depending on the ERP.
