What it is

Site Samurai is construction management software for UK contractors, combining commercial, safety and operational workflows. Commercial tools cover tender management, applications for payment, valuations and variations, early warning notices, final accounts and budget-versus-actual reporting. Safety features include RAMS templates, AI-generated risk assessments, toolbox talks with sign-off, incident reporting, policy management and audit trails. Its AI can also parse BOQs, identify leads from Contracts Finder, analyse safety trends and flag hazards. Xero and Sage Business Cloud connect for two-way invoice, payment and contact synchronisation; Sage 50 desktop and Sage 200 are not supported. CIS checks take place on the HMRC portal, with results and deduction rates recorded in the product. The companion app works offline on iOS 16+ and Android 10+, syncing when connected again. Plans start at £99/mo, with a 14-day trial and no free plan. The service is available on Android, iOS and web.
