What most homeowners go through

Sound familiar?

"The tradesperson said 3 weeks. It's been 2 months."

And they've stopped answering messages. You don't know if they'll come back, what's left to do, or who to turn to.

"You got an invoice you don't understand."

For work that isn't finished. Or duplicating the original quote. You don't know what to refuse and what to accept.

"The plans are in a March email. The photos on WhatsApp."

The quote somewhere on the desk. The ten-year warranty in a drawer. When you need a document, it's an expedition.

"You never really know where your work stands."

Without calling. And when you call, you're told "it's coming along". You've invested your money in this project. You deserve to know.

What MonChantier changes

01

Real-time tracking

The tradesperson posts timestamped photos straight from the site. You receive them instantly. You see the progress without leaving home.

Available at launch

Milestone approval

Each step must be approved by you before the tradesperson can move to the next. Nothing moves forward without your agreement.

Available at launch

All your documents in one place

Quotes, invoices, plans, photos, warranties, insurance — all centralized in one space. Accessible in 2 seconds from your phone.

With SyneraBTP Pro

Is your tradesperson on SyneraBTP Pro?

If your tradesperson uses SyneraBTP Pro, all their updates flow automatically into MonChantier in real time — with nothing to do. You're in the loop the moment they post a photo, approve a step or upload a document.

Automatic synchronization

As soon as the tradesperson updates the project file, you see it instantly on MonChantier.

Invite in 30 seconds

Doesn't your tradesperson know SyneraBTP yet? Invite them straight from the app in a few clicks.

What only SyneraBTP does

Ordinary work-tracking apps show whatever the tradesperson chooses to report. With MonChantier, you view the same file they do, updated in real time — not a summary. And you're not a spectator: you ask for a progress update whenever you want, you approve the steps, you ask your questions in the right place. You manage your project the way you want.

And after the project?

The Home Passport: your home keeps its memory

When the work ends, your file doesn't disappear. It becomes your home's digital logbook — like a car's service book, but for your house. And it follows it for life.

1 · During the project

It builds itself

Photos, plans, quotes, invoices, approvals: everything that goes through MonChantier automatically feeds the Passport. At handover, the complete file for your project is already ready. Zero data entry.

2 · Through the life of the home

Your warranties, watched over

Completion (1 year), two-year, ten-year: your warranties are tracked, with an alert before each expiry. Tradespeople's insurance certificates archived, maintenance reminders at the right time.

3 · At resale

A documented property is a valued property

The full work history, ready to share with the notary or buyer. The Passport transfers to the new owner — your house changes hands, its memory stays.

Coming soon — the Passport will fill up from your very first MonChantier projects
