The Subcontractor Onboarding Checklist

Onboarding a new subcontractor is the least glamorous part of running a project and one of the most consequential. Do it well and the sub starts on schedule with everything in order. Do it in a rush — because the crew is already booked and the clock is running — and you inherit whatever gaps you didn’t catch: an expired policy, a missing endorsement, a misclassified worker. Here is the checklist we’d hand any general contractor, built from the same requirements we automated into TradeGuard Pro.

This is a general operational guide, not legal or insurance advice — your contracts and local regulations set the real requirements. Use it as a starting framework and confirm specifics with your broker or attorney.

1. Company & Legal Identity

Before anything else, confirm you are hiring who you think you are hiring.

• Legal business name, DBA, and business structure (LLC, corporation, sole proprietor)
• Federal EIN / tax ID and a completed W-9 for tax reporting
• Active contractor’s license for the trade and jurisdiction — verified against the state license board, not just a number on a form
• Business address, primary contact, and after-hours contact

2. Insurance & Risk Transfer

This is the section that protects your company when something goes wrong. A missing item here is not a paperwork gap — it’s an uninsured loss waiting to land on your policy.

• Certificate of Insurance (COI) showing active general liability, workers’ compensation, and auto coverage
• Coverage limits that meet or exceed your contract and the project owner’s requirements
• Additional insured endorsement naming your company — ongoing and completed operations
• Waiver of subrogation and primary & non-contributory wording
• The policy expiration dates, recorded so you’re alerted before they lapse mid-project

If any of those terms are unfamiliar, they’re worth ten minutes: we broke them down in the COI clauses that actually protect you.

3. Contract & Scope

• Signed subcontractor agreement with a clear scope of work
• Payment terms, retention, and lien-waiver process defined up front
• Indemnification and insurance requirements written into the contract — not just assumed from the COI
• Schedule, milestones, and change-order procedure agreed before mobilization

4. Compliance & Safety

• Safety program and any required certifications (OSHA training, site-specific orientation)
• Worker classification confirmed — employees vs. 1099, to avoid misclassification liability
• Any jurisdiction-specific requirements: local business registration, prevailing-wage documentation on public work, permits tied to the trade
• Emergency contacts and incident-reporting procedure shared with the sub’s foreman

5. Payment & Records Setup

• Banking / payment details and preferred invoicing method
• A single file (digital, not a desk drawer) holding every document above
• A renewal calendar for anything that expires — licenses and COIs especially

Where Onboarding Actually Breaks

The checklist is the easy part. The failure mode is that onboarding is a one-time event but compliance is continuous. You verify everything on day one, the sub starts, and then — three months in — their insurance quietly lapses and nobody notices, because the folder that said “compliant” in March never updated itself. The onboarding was perfect; the ongoing tracking is what failed.

That’s the reason a static checklist eventually needs a system behind it: something that stores each sub’s documents, watches the expiration dates, lets subs upload their own renewals through a portal, and flags anyone who has slipped out of compliance — without you re-running this whole checklist by hand every quarter.

That’s exactly what we built TradeGuard Pro to do: turn this checklist into an always-on system with a self-serve sub portal and automatic expiry alerts. Want it, or a compliance tool shaped around your own process? Talk to us at Rebel Studios.
