Mobile App for Site Teams

Empower your teams on the ground

Give your site teams the tools they need to stay connected and efficient with our integrated mobile app. Staff can raise purchase orders, submit goods received notes (GRNs), log timesheets and complete mobile forms – all from their phone or tablet. With data feeding directly into your central system, head office gains real-time visibility and costly delays due to paperwork or miscommunication are eliminated.

Integrated CVR Module

Stay on top of project profitability

With margins under constant pressure, accurate cost value reconciliation (CVR) is essential. The CVR module in Evolution Mx Enterprise gives commercial teams a powerful, structured tool to track cost performance, measure committed costs and compare actuals against budget, so you can catch potential issues early, maintain profitability and report with confidence.

Allowed us to support the company’s growth from £18m to circa £33m with little increase in staff.
