Construction management software in Québec: the guide to choosing well

GST/QST, CCQ payroll, CNESST, RBQ, Law 25: 7 criteria for choosing construction software built for Québec — and the traps of American tools.

Searching for "construction software" is easy — there are hundreds. Searching for software that understands that a Québec estimate carries GST and QST, that a CCQ worker does not have the same rate depending on trade and sector, that a serious accident must be reported to the CNESST within legal deadlines, and that your employee files fall under Law 25 — that is another story. This guide gives concrete criteria, without jargon, to decide.

Why generic tools get stuck in Québec

The big American platforms are excellent products — for their market. What they don't do, and what you will therefore do "on the side" in Excel or at the accountant's:

• Taxes: GST 5% + QST 9.975%, computed line by line, with the special case of the holdback (tax follows precise rules at the time of the holdback and its release).
• CCQ payroll: rates by trade and by sector, premiums, vacation (the famous 13% remitted to the CCQ — which is NOT net pay), overtime under the collective agreement.
• The CNESST: a serious event must be reported fast, with deadlines in hours — not "when we have time". A dated incident register makes the difference during an inspection.
• The RBQ: your licence number must appear on your estimates and your website; its expiry must be watched.
• Law 25: as soon as you hold personal information (clients, employees, SINs), you have obligations — and your software is your main data subcontractor. We wrote a dedicated article.
• French: your employees on the job site work in French. A tool the crew doesn't use is worth nothing, whatever its features.

The 7 criteria that really separate them

1. The complete cycle, not pieces

The real gain comes from the chain: the signed estimate becomes a project, the project tracks its costs by category (job costing), the hours clocked on the job site feed payroll preparation, progress triggers invoicing with holdback. Every retyping between two tools is an error waiting for its moment.

2. Native Québec taxes and holdbacks

Test it in a demo: create an invoice with a 10% holdback, then release the holdback. If the taxes don't follow correctly, everything else is cosmetic.

3. CCQ payroll — prepared, honestly

Nobody serious "transmits" your CCQ payroll for you in $100/month management software. The right standard: accurate indicative calculations (rates, deductions, CCQ vacation outside the net), and clean exports for your accountant or your payroll software. Be wary of promises bigger than that.

4. The field first

Your foremen have a phone, not a desk. Demand an app that works offline (job sites in dead zones exist), with clock-in, daily reports, photos and incident reports — synced when the network returns.

5. The legal electronic signature (LCCJTI)

An image of a signature pasted into a PDF proves nothing. The LCCJTI requires the integrity of the document and the identification of the signer: cryptographic fingerprint, timestamp, recorded consent.

6. Your data: where, and exportable

Two questions for the vendor: "Where is my data hosted?" and "How do I leave with it?". The right answers: a precise location (not "in the cloud"), and CSV/PDF exports available at any time — even after cancellation.

7. A price you understand

In Canadian dollars, published, without a "call us" to know the amount. Beware of the "per user" model in US dollars: multiplied by a team and the exchange rate, the $199 shown quickly becomes double.

The questions to ask in a demo (copy and paste)

• "Show me an invoice with a 10% holdback: what happens to GST and QST at the release?"
• "A CCQ worker, carpenter-joiner in the light residential sector: where do the rates come from, and is the 13% vacation in the net or outside the net?"
• "Where is my data hosted, and who are your subcontractors?" (Law 25 — the list must be public.)
• "Cut the Wi-Fi: show me a clock-in and a job-site report offline."
• "I cancel tomorrow: how do I get my clients, invoices and documents back?"
