The job is done. Not almost done — actually done. The inspection passed, the client walked through this morning, and the keys were handed over at noon. Six months of work, finished.

The site trailer needs to be back at the yard by Friday. There's a folding table covered in paper: timesheets, delivery slips, a signed change order from July, inspection reports, photos from the foundation pour. Everyone's already thinking about the next job.

So he loads it all into a banker's box, writes the project name on the side with a marker, and puts it in the back of the truck.

It'll make it to the office. Eventually. The box will sit on a shelf until the accountant calls, or there's a labour complaint, or a client claims something wasn't done right. And then he'll open it and realize half of what's in there has no context anymore.

The right time to organize a project's documents is the day it closes.

Why waiting costs more than an hour

When you're still on a project, you know what everything means. You know why there are two versions of the July 15th delivery slip. You remember that the foreman's absence in week three was a documented injury, not an unexplained gap.

Wait two months and you're guessing. Wait six months and you're reconstructing from memory.

Payroll audits, contractor disputes, and warranty claims don't always arrive quickly. In Quebec, the prescription period for certain construction defects runs for years. If your documents aren't in order when the call comes, you'll be sorting under pressure — and some of it won't be findable.

An hour at project close is worth a day of scrambling later. Sometimes more.

Payroll documents: everything, together

For every project, hold on to:

Signed timesheets. Not the drafts — the final versions, signed by the employee and validated by the foreman. If a timesheet was corrected, keep both the original and the corrected version with a note explaining why.

Pay stubs or equivalent records for every employee who worked on the project. If you use a tool like Heuro, your payroll data is already structured by site and exportable — you don't need to dig through spreadsheets or call your office manager.

Premium calculations. Travel, remote-site, elevation — whatever applied to this project. If a worker questions his pay from this job a year from now, this is where you find the answer. Not in your memory.

Absence and leave records. Who was off, when, and why. This matters for tax audits and for explaining gaps if someone disputes their paid days.

Quebec's tax laws and employment standards legislation set specific retention periods. Your accountant can tell you exactly how many years apply to your situation — but think in terms of years, not months. Don't sort too fast.

Site documents worth keeping

Signed delivery receipts. For significant materials, a signed receipt is your proof you received what you paid for. It also protects you if a supplier disputes quantities six months down the road.

Purchase orders. Especially for anything with significant cost or specific specifications.

Signed change orders. Every extra your client approved, with their signature. Without the client's sign-off, you have a conversation. With it, you have a document. This is your protection if a client disputes scope months after you've moved on.

Dated site photos. Especially for concealed work — foundations, in-wall plumbing, structure before drywall — and site condition at handover. A photo with a timestamp can close a dispute faster than any formal report.

Inspection reports. Municipal inspections, engineer sign-offs, any formal certification the building received.

What you can let go

Unsigned drafts. Obvious duplicates. Internal memos with no legal or operational value. Keeping everything without sorting makes the box unusable when you actually need it.

A system that doesn't live in one person's head

The real problem with the banker's box isn't that it's disorganized. It's that only one person understands it.

Your office manager knows what's in there. She knows what each document represents. But the day she's on vacation, between jobs, or simply not at her desk when someone needs something — you're the one digging.

A simple structure: one folder per project, same sub-folders every time. Payroll. Site documents. Client correspondence. Change orders. Whether it's physical or digital matters less than whether it's consistent. Anyone on your team should be able to find a document without calling anyone.

The 18-employee contractor in Montérégie we describe in our case study largely eliminated the end-of-project reconstruction problem because his payroll data is organized by site by default in Heuro. His office manager spends the close-out hour on the operational documents — not on reassembling timesheet history.

It only works at the right moment

The banker's box in the back of the truck becomes a problem around March. The folder created on the last day of the project stays useful for years.

One hour. The same checklist every time. Before the trailer leaves the lot.

Keep all signed timesheets, payroll records, and premium calculations for every project
Signed change orders, delivery receipts, and dated photos are your protection against disputes
A consistent folder structure — same sub-folders every project — is worth more than anyone's memory
Retention periods are measured in years; check with your accountant before discarding anything
