What’s Shown on a Certificate of Insurance?

A Certificate of Insurance serves as proof of insurance—think of it like an insurance “ID card” for your business. The standard form used to provide evidence of insurance is an ACORD Form, also known as ACORD 25. This document outlines essential coverage details, including:

  • Named Insured: The business or individual covered by the policy.

  • Types of Coverage: Policies listed on the COI can include:

    • General Liability Insurance

    • Commercial Auto Insurance

    • Commercial Umbrella Insurance

    • Workers' Compensation Insurance

  • Policy Start and End Dates: Shows when coverage begins and expires.

  • Coverage Limits: The maximum amount the policy will pay for claims.

  • Additional Insureds: Other parties, like a client or project owner, who are also covered under the policy.

  • Certificate Holder: The entity requesting proof of insurance. Their name and details appear on the document.

Many clients want to ensure you comply with Texas insurance requirements before working with you. Providing them with a valid **COI—especially an ACORD 25 form—**can help you earn trust, secure contracts, and demonstrate professionalism.

 

Why You Need a Certificate of Insurance

Having a COI is essential for small business owners, because many companies and clients won’t even consider hiring you if you can’t show proof of coverage. Meeting Texas insurance requirements helps you:

  1. Win More Business: Stand out among competitors by presenting valid coverage.
  2. Stay Protected: Avoid paying out of pocket for unexpected losses or accidents.
  3. Build Credibility: Demonstrate professionalism, reassuring clients that you take your responsibilities seriously.
  4. Meet Industry Requirements: Certain trades require a COI for compliance—this is especially relevant if you’re working under Texas contractor insurance guidelines.
