The verdict in three sentences
For a structural contractor with 40 to 100 employees in Toronto, the choice is between a market tool (Procore, Fieldwire, Buildertrend type) at EUR 50 to 150 per user per month and custom software at EUR 30,000 to 70,000 (about CAD 45,000 to 105,000). Custom becomes relevant when your daily reports, photos and hours must feed your own budget tracking by trade package. The gain that justifies the investment is the margin recovered on overruns, around 5% of site revenue.
Paper logbooks and WhatsApp: where margin leaks
A project manager running 4 to 6 sites in parallel receives dozens of unsorted photos and voice notes on WhatsApp every day. Crew hours arrive on paper on Friday. By the time an overrun shows up, it is too late to react or to bill it as a change order.
| Source of loss | Typical 2026 situation | Estimated impact on an EUR 800,000 job | Software response |
|---|---|---|---|
| Hours not tracked by task | Weekly paper timesheets | 1.5 to 2% of margin | Mobile time entry by task and package |
| Unbilled extra work | Verbal request from the owner | 1 to 2% | Change order form with photo and tablet signature |
| Late material deliveries | Calls and texts | 0.5 to 1% | Shared procurement schedule |
| Undocumented deficiencies | Photos lost in WhatsApp | 0.5% | Geotagged photos linked to the drawing |
| Delay penalties | Spreadsheet schedule not updated | Variable, per contract liquidated damages | Progress alerts |
Market tool or custom: the costed comparison
The prices below are a 2026 order of magnitude. For a 60-employee company, count 15 to 25 active users (project managers, superintendents, foremen, office).
| Criterion | Market tool | Custom |
|---|---|---|
| Entry cost | EUR 0 to 3,000 of setup | EUR 30,000 to 70,000 |
| Recurring cost for 20 users | EUR 12,000 to 36,000 per year | EUR 5,000 to 12,000 per year of maintenance |
| 5-year cost | EUR 60,000 to 180,000 | EUR 55,000 to 130,000 |
| Daily reports with photos | Yes, standard format | Yes, your company's format |
| Budget tracking by package and task | Partial | Full, aligned with your takeoffs |
| Payroll and accounting link | Generic export | Dedicated connector (QuickBooks, Sage, payroll) |
| Offline mode on site | Variable | Built in from the start |
| Time to go-live | 2 to 4 weeks | 12 weeks |
A custom project breaks down as: offline mobile app for daily reports and time entry (EUR 12,000 to 20,000), budget tracking back office (EUR 10,000 to 25,000), change order and deficiency module (EUR 5,000 to 10,000), payroll and accounting connectors (EUR 3,000 to 15,000).
What a useful daily report contains
A good daily report takes 5 minutes on a phone, even without signal in a basement. It contains weather, headcount by trade, hours by task, deliveries received, photos linked to a zone of the drawing, safety incidents and requests from the architect or engineer. The software automatically derives progress and the gap between planned and used hours, package by package. That daily reconciliation, not the data entry itself, is what recovers margin.
Mini case study
Thomas, project manager at a 60-employee structural contractor in Toronto, oversees EUR 9 million of annual revenue. If the tool recovers only 1.5% of margin on overruns (the target potential being 5%), the gain reaches EUR 135,000 a year. The custom project costs EUR 55,000 plus EUR 8,000 of annual maintenance. Payback comes in 5 months. By comparison, a market tool at EUR 100 per month for 20 users costs EUR 24,000 a year, without the package-level budget tracking that generates most of the gain.

FAQ
Will crews really use the app?
Yes if entry takes under 2 minutes and works offline. Successful projects target 3 mandatory fields at most for daily time entry.
How long until go-live?
Allow 12 weeks for the mobile app, back office and a first connector, with a pilot on 2 sites during the last 3 weeks.
Can we keep our estimating and takeoff software?
Yes. The tool imports takeoffs and package budgets from your current software, which costs EUR 3,000 to 6,000 for the connector depending on the vendor.
Is the data usable in a dispute?
Photos are time-stamped and geotagged, and change orders are signed on a tablet. This evidence carries weight in a claim worth tens of thousands of euros.
Is it worthwhile for a 20-person company?
Rarely. Below EUR 3 million of revenue, a market tool at EUR 50 to 80 per user per month is the better fit.
