Our co-founder Greg McClelland joined a panel on the Fire Safety Stage—Bridging the gap between subcontractors and main contractors—to talk about how better communication, clearer data standards and smarter technology can transform project delivery.
Key takeaways
Standardising data capture so everyone can see what’s been done, by whom and when delivers consistency
Subcontractors need tools to help them improve the quality of their work, that integrate with other systems.
Handovers require robust reports. Just because the record is digital, doesn’t make it good.

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.

I have had an incredible experience overall working with the team at Onetrace. Not only has their app helped us streamline and customise our services but also their team have always been helpful and open to ideas for features while valuing us as clients and what is important to us.

From day one, the service has been nothing short of amazing. Daniela, Natasha, and Fatah don’t just help — they genuinely go above and beyond every single time. Any issue or question I’ve had was handled instantly, with care and professionalism. I switched from another software, and there truly is no comparison. They’ve set the bar incredibly high.

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.

Brilliant software and excellent customer service. Easy to use and caters for all of our needs. Any time we have had any questions or issues we have been able to resolve over the phone without any delays or problems. Highly recommended.

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.

I have found Onetrace to be an extremely useful software but most importantly the support and speed of response by the team within the software is second to none. Their willingness to listen to and act on customer feedback is so refreshing.

Excellent system/App. Flexible enough to accommodate to our needs and well thought through. The online help in particular deserves a 6th star.
