As answered by people managing Moz and SubDoc.
SubDoc's answer:
SubDoc offers a self-service compliance platform with zero setup friction. Instead of forcing subcontractors to register accounts and create logins (the leading cause of collection delays), SubDoc sends a secure, passwordless magic link where vendors can upload certificates in seconds. It also features built-in AI-powered OCR that automatically scans uploaded documents to extract policy numbers, limits, dates, and endorsement compliance status (Additional Insured, Waiver of Subrogation) instantly.
SubDoc's answer:
Traditional compliance tracking platforms (like TrustLayer, myCOI, or Certificial) are sales-led, expensive, and introduce high friction for vendors. Operations teams choose SubDoc because it is fully self-service, publishes flat and affordable pricing transparently, supports international multi-currency tracking out-of-the-box, and eliminates subcontractor login friction entirely.
SubDoc's answer:
SubDoc's primary audience includes commercial general contractors, subcontractors, property managers, compliance administrators, and mid-market operations teams who need to track insurance certificates (COIs), W-9s, and licensing requirements across 5 to 500+ vendors without enterprise complexity or cost.
SubDoc's answer:
Tracking contractor insurance compliance is notoriously painful. Teams are usually stuck between chaotic manual spreadsheets or bloated, expensive enterprise software. SubDoc was created to fill this gap: providing a simple, modern, self-service tracker that automates the chasing via magic links and uses smart AI extraction to speed up verification, giving operations teams their time back.
