The verdict in three sentences
A custom installer scheduling app costs CAD 37,000 to 74,000 (about EUR 25,000 to 50,000) in 2026 for a Toronto joinery company with 40 installers, delivered in 3 to 5 months. Its value lies in something generic SaaS tools handle poorly: tying every job to manufacturing and delivery dates for the windows, so a crew is never sent to install a unit that has not arrived. On 2,600 jobs a year, eliminating 8 to 12% of wasted trips is enough to pay the tool back in under two years.
Why the whiteboard costs half-days
The owner of an exterior windows and doors company schedules 40 installers on a magnetic board updated on Fridays. When the vinyl or aluminium supplier pushes a delivery by 3 days, the information reaches the site supervisor by phone, rarely the installer. Result: a crew of two drives out, finds no frames, and drives back. On a job 45 minutes from Toronto, that is half a day lost for two people and a truck.
| Source of loss | Observed 2026 frequency | Estimated unit cost | Annual cost (2,600 jobs) |
|---|---|---|---|
| Missing or incomplete delivery | 5% of jobs | CAD 560 | CAD 72,800 |
| Wrong measurements or product | 2% | CAD 770 | CAD 40,000 |
| Customer absent, no access | 2.5% | CAD 370 | CAD 24,000 |
| Sign-off sheet lost or unsigned | 4% | CAD 130 follow-up | CAD 13,500 |
| Poorly ordered daily routes | daily | 35 min per crew | about CAD 20,700 |
These are 2026 order-of-magnitude figures to recalculate with your own data, but they show the loss often exceeds CAD 150,000 a year for a business this size.
What the app does, and what it costs
The core is a schedule that only offers an install date once the supplier order is confirmed and delivery to the warehouse is validated. On the installer side, a mobile app shows the day's job, drawings and measurement photos, and lets the customer sign the completion sign-off sheet on screen, with photos of any snags.
| Module | Content | 2026 price (CAD) | Timeline |
|---|---|---|---|
| Supervisor schedule | Weekly view per crew, drag and drop, conflicts | 12,000 to 21,000 | 5 to 6 weeks |
| Manufacturing and delivery link | Supplier order status, install blocking | 7,500 to 15,000 | 3 to 4 weeks |
| Offline installer app | Day's job, drawings, photos, checklist | 9,000 to 18,000 | 4 to 5 weeks |
| Signed sign-off sheet | Signature, photographed snags, PDF sent | 4,500 to 9,000 | 2 weeks |
| Customer SMS D-2 and D-1 | Presence confirmation, one-click reschedule | 2,200 to 4,500 | 1 week |
| Quote or ERP connection | Import of sold jobs | 2,200 to 7,500 | 1 to 2 weeks |
A minimal scope (schedule, delivery link, installer app, sign-off) sits around CAD 37,000 to 47,000. The full version with SMS, route optimization and quoting software connection reaches CAD 67,000 to 74,000. Hosting and maintenance: CAD 600 to 1,350 per month.
Custom build or off-the-shelf SaaS?
Field scheduling software costs CAD 45 to 90 per installer per month, or CAD 21,600 to 43,200 a year for 40 installers. These tools handle appointments and signatures well, but few can block an install until delivery is confirmed at the warehouse. Over 5 years, SaaS costs CAD 108,000 to 216,000, against CAD 52,000 to 112,000 for a custom build including maintenance. SaaS remains relevant under 15 installers or if your suppliers never share reliable dates.

Marc, owner of a 40-installer joinery company in Toronto, completes 2,600 jobs a year. He picks a CAD 56,000 scope (schedule, delivery link, installer app, sign-off, customer SMS), plus CAD 900 per month of maintenance. Cautious assumption: about 250 wasted trips avoided among jobs hit by a missing delivery or an absent customer, at CAD 490 on average. Gain: CAD 122,500 a year, plus about CAD 10,000 of sign-off follow-ups avoided. First-year cost: CAD 66,800. Payback in 6 to 7 months, and installers save about an hour a week of phone calls.
FAQ
Does the app work without signal on site?
Yes, the installer app is built offline-first: the day's job downloads in the morning and the signed sheet syncs once signal returns. This represents about 15% of the mobile budget.
Can we pull delivery dates from suppliers automatically?
If suppliers send acknowledgements by email or portal, reading them can be automated in 60 to 80% of cases. Otherwise, the warehouse clerk confirms receipt in 10 seconds on a tablet.
Is an on-screen signed sign-off legally valid?
A simple electronic signature with timestamp, photos and instant PDF delivery to the customer is strong evidence of completion under Ontario practice. An advanced signature can be added for CAD 0.75 to 2 per document.
How long to train 40 installers?
A 45-minute session per crew is usually enough, with a month of support. Installers use only 4 screens: day, job, photos, sign-off.
Can we launch a first version faster?
Yes, an MVP with schedule, delivery link and sign-off can ship in 10 to 12 weeks for CAD 37,000 to 41,000, with SMS and route optimization in phase two.
