SUPPLY CHAIN
SIMPLIFIED

The problem:

Chasing documents by email, verifying CIS status manually, and tracking insurance expiries in spreadsheets means compliance gaps are only discovered when it is too late — during an HMRC check or when an unverified subcontractor is already on site.

The fix:

One onboarding link per subcontractor. Self-service document collection, HMRC CIS verification, compliance dashboards, and automated expiry alerts — all in one place.

WHY TEAMS SWITCH TO SITE SAMURAI FOR SUPPLY CHAIN

The issue is not finding subcontractors. It is onboarding them quickly, verifying CIS status, and knowing when documents lapse — before it becomes a compliance problem.

Self-Service Onboarding

One onboarding link per subcontractor replaces email chasing entirely. Subcontractors submit CIS details, insurances and qualifications through a self-serve portal. Your team reviews and approves from a single compliance dashboard.

CIS Verification

Run HMRC CIS verification workflows and store the outcome with timestamps against every subcontractor record. Status changes and lapses are flagged automatically so your team can act before incorrect deductions become a compliance issue.

Compliance Tracking

Track insurance certificates, qualifications, training records, and CIS status with automated expiry alerts. Compliance dashboards show exactly who is approved, who is pending, and who has lapsed.

Whereabouts & Performance

Weekly whereabouts logging shows where your subcontractors are working across all projects. Performance scoring helps you build a reliable approved list based on actual track record.
