You fit by the square metre, so quote by the minute
Partitions, suspended ceilings, insulated linings, jointing: the same works come back on every job, only the surfaces change. MaitreChantier keeps your rates per square metre and turns a take-off into a quote without retyping it.
Your day-to-day, point by point
The situations that eat your evenings — and what the platform does about each of them.
Today
The same three works, retyped on every quote
With MaitreChantier
Partition on rails, suspended ceiling, jointing: they live in your library with your rate. You change the surface, nothing else.
Today
The main contractor pays per progress statement
With MaitreChantier
Invoice a share of the signed quote as the work advances: the platform deducts what was already invoiced and keeps the numbering right.
Today
The surfaces move once you are on site
With MaitreChantier
Adjust the quantities, resend the quote for signature: the invoices that follow are based on the amount actually agreed.
Today
At what price per square metre do you stop earning?
With MaitreChantier
Each work carries its cost price: the margin of the quote is displayed while you are still free to change the price.
What you gain, every week
Quoted in square metres
Partitions, ceilings, jointing: enter the surface, the line prices itself — including insulation when it is part of the work.
Progress invoices for contractors
Invoice what is done, when it is done, on a job that runs for months — with the previous invoices deducted.
Your rates, not a catalogue's
Your library holds your selling price and your cost price, so two similar jobs are quoted the same way.
Margin per job, not per year
Boards, rails and hours are booked against the job: you know which site paid and which one ran long.
Crews on the right site
Assign your fitters per week and shift a site when the trade before you is late.
Take-off on the phone
Measure, enter, send: the quote leaves from the site rather than from the kitchen table at midnight.
What a drywall quote looks like
An extract from an interior fit-out: three works, three surfaces, totals computed as you type.
| Description | Qty | Unit price | VAT | Total excl. VAT |
|---|---|---|---|---|
| BA13 partition on rails, insulation included | 48 m² | €52.00 | 10 % | €2,496.00 |
| BA13 suspended ceiling | 32 m² | €58.00 | 10 % | €1,856.00 |
| Jointing and taping | 140 m² | €14.00 | 10 % | €1,960.00 |
| Total excl. VAT | €6,312.00 | |||
The same quote carries the progress invoices: 40 % at the end of the first phase, the rest on completion.

The monthly statement for the main contractor
You work per square metre for a main contractor who pays on progress. Each month the statement picks up the signed quote, declares the progress and deducts the previous statements — retention money included.
How it goes, from quote to payment
The take-off becomes a quote
Pick the works, type the surfaces, add a section per level or per flat. The PDF goes out the same day.
Fit, and log as you go
Boards ordered, hours worked, extras agreed: everything is attached to the job while it is still fresh.
Invoice the phases
A progress invoice per phase, the balance at the end, and a clear view of what is still owed.
Frequently asked questions
- I subcontract for main contractors — is that supported?
- Yes: companies are clients like any other, with progress invoices, their own payment terms and their document history.
- Can I quote per square metre and per linear metre on the same document?
- Each line carries its own unit and rate, so a quote can mix square metres, linear metres, pieces and fixed prices.
- Do I see the margin before sending the quote?
- The estimated margin updates as you price, based on the cost price stored with each work.
