What it does

Where does the structure price come from?
From three mid-range homes in the studio's history. Average: €233/m² built. history · 3 projects · 2024–2026

Your prices, not a generic database

The price per square meter for each range comes from the studio's history, and the system tells you which projects it used.

PEC · VAT included €267,245

From PEM to PEC, in plain view

From base cost (PEM) to final total (PEC): overheads, contractor's profit and VAT, each on its own line. No figure in the summary comes out of nowhere.

You correct it by talking

Say “drop this line item” or “upgrade the bathroom finish” and it recalculates the total. If something isn't in your history, it says so.

Runs on your server

The prices and the history stay at the studio. No personal data is involved: just measurements and construction prices.

Questions before you start

Does it work with my current price database?

Yes. Setup starts by gathering what you already have: past estimates, measurements and the price database you use today. That's where the prices it proposes come from. You don't need to switch estimating software.

What about a line item I've never done?

It says so. If a line item isn't in your history, it doesn't make up a price: it flags it for you to fill in. Next time, it already knows it.

Can I correct the estimate by hand?

Yes, by talking or by editing the table. Every change recalculates the PEM, overheads, contractor's profit, VAT and PEC, and the PDF comes out with the corrected version.

Where are my prices stored?

On the studio's server. Neither the prices nor the history ever leave it, and if you stop the service one day, they stay where they were: they're yours.
