Frequently asked questions
Is PlanRadar good for small contractors?
PlanRadar can work for smaller teams, but its per-user pricing model and configuration requirements may represent more overhead than necessary for UK SME contractors. Site Samurai offers flat pricing with unlimited users, making it more accessible for growing teams.
Can PlanRadar handle payment applications?
PlanRadar is focused on field quality management and does not include native commercial workflows such as applications for payment, valuations, or retention tracking. These processes would typically need to be managed in a separate system.
How does PlanRadar pricing work?
PlanRadar typically uses a per-user licensing model, which means costs increase as your team grows. Site Samurai uses flat pricing with unlimited users, so your costs remain predictable regardless of how many people need access.
Can I use PlanRadar for RAMS?
PlanRadar does not include native RAMS generation or CDM 2015 compliance workflows. UK contractors needing RAMS capability would need additional tooling. Site Samurai includes RAMS as a core feature integrated into project delivery workflows.
What is the difference between PlanRadar and Site Samurai?
PlanRadar specialises in field quality management, defect tracking, and photo documentation. Site Samurai is a broader operational platform combining field workflows with UK compliance (RAMS, CIS, CDM), commercial controls (payment applications, valuations), and subcontractor management in one integrated stack.
