The starting point

In many companies, cost control doesn't keep pace with the complexity of the works

Budgeting and control still rely on fragmented tools and obsolete technology. The result isn't just disorder: it's profitability discovered when it can no longer be corrected.

Scattered, disconnected spreadsheets

Someone built the unit price analysis in Excel, the latest version lives on their laptop, and every new project starts by copying the previous file.

Duplicated information

Physical progress is entered by hand, progress billing is redone in another system, and material purchases never hit the work item cost.

Knowledge that depends on one person

The budget logic lives in the head of whoever builds it. If that person leaves, the company's costing criteria leave with them.

Little real-time control

When actual cost exceeds budget nobody finds out until month-end close — or until the project has already lost money.

The solution

Real control of budgets and costs on a single platform

A single engine connects the approved budget with actual costs and site progress — on odoo 20, integrated with your ERP.

Real, connected control

Direct connection between the budget and site execution.

Full integration

Approved budget, actual costs and site progress in real time.

The flexibility of Excel, without the errors

All the ease of building your budget, with the safety of a tamper-proof, auditable database and no broken formulas.
