OPOC Verified Customer Reviews (2026)

Onetrace is a connected workflow for subcontractors, bringing job planning, site evidence, and compliance sign-off into one place, from first visit through to handover. Rather than chasing spreadsheets, paper forms, and separate apps, teams get documentation that's ready for clients, main contractors, and regulators. It's construction management software built around how subcontractors actually work. Fire protection contractors use Onetrace as fire protection software, attaching photos, approval forms, and sign-offs to the relevant job and location, so proving a compliant installation takes minutes, not a search through old files. It's also used across drylining, roofing, and M&E work, with live oversight of projects, timesheets, and progress. Practical tools include customisable forms, drag-and-drop scheduling, GPS time-tracking, cost calculation, and drawing markups with photo evidence, all from a mobile device on site.
