Today, one project lives in five different places.
The notebook in the van, the photos in WhatsApp, the hours on a scrap of paper, the quotes in Excel. OpenChantier brings it all together, per project.
The project is scattered
Every piece of information lives in a different tool — and nobody can find anything three months later.
Photos get lost in WhatsApp
No way to find the photo of the wall before the repair when a client disputes it.
Hours end up in a notebook
Copied out on Sunday night, often approximate, never tied to the real cost.
Quotes get retyped in Excel
The same template rewritten every time, VAT errors, numbering done by hand.
Payment chasers slip through
You realise three months later that an invoice was never paid.
The client calls to ask where things stand
Three calls a week to repeat what you already said yesterday.
Everything together, per project
One app, filled in from the site, viewable by your client.
Time-stamped photos, filed by project
Taken on your phone, sorted automatically, found in two seconds.
Hours logged in two taps
Timer or quick entry, per person and per project, cost calculated automatically.
Quote turned into an invoice in one click
Price catalogue, correct VAT rates, automatic numbering, compliant PDF.
Payment reminders sent on their own
D+1, D+8, D+30 — with the online payment link in the email.
Your client follows the project live
One link to send, no account to create: they see progress and photos.
