Guide

How to keep your site margin under control

A simple system to monitor costs and revenues project by project, without waiting until the end of the job.

Glossary

Construction site margin

The construction site margin is the difference between a project's revenues and the direct costs incurred to carry it out, expressed in absolute value or as a percentage.

Feature

Site accounting, simplified

Construction job costing tracks the costs and revenue of a single project: labour, materials, equipment hire and subcontractors, measured against the quote. With archim every hour, delivery note and invoice is attributed to the job automatically, so your margin is current every day instead of at handover.

Want to calculate margin in real time?

archim updates margin as hours, materials and invoices enter the system.
