Every scope change, documented and billable.

Decisum builds your variation register automatically from project email.

You know these projects.

The layout change

The customer asked for it over email. Engineering did the work. Nobody raised a variation, and it was never billed.

The delay claim

A supplier was six weeks late and the schedule slipped. The claim was real. The paper trail was thin, and the claim went nowhere.

The inbox that left

The project manager who knew the history moved on. The history was in his inbox. So was your evidence.

How it works

1
Capture. Forward or CC project mail to your project's capture address.
2
AI proposes. Decisum reads the mail and proposes events: changes, delays, site instructions.
3
You confirm. You confirm what's real and dismiss what's not.
4
Notice or dossier. When you need a notice or an evidence dossier, it's one click.

Who it's for

Decisum is built for machine builders, system integrators, and installation contractors who deliver projects under contract.

It is not for general document management, and it is not a legal tool. The register helps you get paid for real work; you decide what to send, and to whom.

Pilot offer

Eight weeks, on one live project, for €150 per month. We set it up with you, and you work directly with the founder.
