Questions to ask before you switch
What is construction software for subcontractors?
Construction software for subcontractors is a digital platform that helps specialist trade firms plan work, manage site teams, and prove compliance. Onetrace is built specifically for this, serving high-compliance trades like fire protection, dry lining, insulation, and roof access
What is Onetrace and who is it for?
Onetrace is construction management software built specifically for subcontractors. It replaces paper forms, spreadsheets, and disconnected apps with one platform. Over 1,000 subcontractors use it, including passive fire protection, dry lining, insulation, roofing, M&E, and other high-compliance trades.
How does Onetrace help subcontractors manage compliance and site documentation?
Onetrace turns site compliance into a live digital record instead of paperwork assembled after the fact. Site teams capture timestamped photo evidence, complete custom forms with mandatory fields, and collect digital signatures for RAMS and toolbox talks, all linked to the exact project location.
Is Onetrace suitable for fire protection, dry lining, insulation, and other high-compliance trades?
Yes. Onetrace started in passive fire protection, one of construction's most compliance-heavy trades, then expanded to other specialist trades with the same evidencing needs.
Does Onetrace help subcontractors meet Building Safety Act 2022 requirements?
Onetrace doesn't certify compliance with the Building Safety Act, but it gives subcontractors the tools to build the records the Act requires. The platform captures a complete record that supports Gateway 2 and Gateway 3 submissions with organised evidence tied to a point on the building.
Can Onetrace work for the "golden thread of information"?
Onetrace helps subcontractors build a continuous record the golden thread calls for. It links every photo, form, approval, and signature to the exact project, location, and installation as work happens. That gives contracts managers a searchable digital history to hand over at each stage of a project.

Onetrace is rated 5.0 on Google Reviews
I've been using Onetrace for a year now, and it has been incredibly handy for generating reports and easily sharing them with clients. But beyond that, the customer service is outstanding.

Our clients and staff are very happy, its useability for our site team and back office is great and the reports produced for our clients are informative and professional. I wouldn't hesitate to recommend this to other business's looking for great software.

I am so pleased with Onetrace, it allows me to do everything i need from a firestopping point of view and a building company when it comes to reporting. The team are constantly updating and improving their features, forever pushing the limits of what the app is capable of.

Absolute game changer for photographic reporting. I use this for fire protection seals. The set up is easily customised to individual requirements and saves having to upload photographs and information manually.
