Shield your construction projects from unreliable subcontractors with instant reliability scores.
Independent construction operators suffer massive profitability losses and mental exhaustion from unreliable subcontractors and uncontrolled scope creep in freelance projects.
SubShield vets subcontractors through a community-driven rating system and provides real-time alerts for red flags like delays or no-shows. Operators can track sub performance across projects and blacklist unreliable ones instantly. This eliminates guesswork, reduces losses from bad hires, and restores peace of mind.
