COIs for One-Time Jobs and Short-Term Vendors: A Fast Process That Still Protects You

By SubCover HQ · Updated Oct 29, 2026 · 2 min read

The riskiest certificates are often the ones that feel too small to bother with: a tree crew for one afternoon, a sub filling in for two days, a handyman fixing a gate at one property. Short jobs get skipped because collecting a COI feels slower than the work. But an injury or property damage claim is just as expensive on day one as on day ninety. Here's a process that's fast enough for one-off work.

Why short jobs slip through

Set a short-job standard in advance

Write one simple requirement list for low-risk, one-time work and a stricter one for higher-risk work like roofing, tree removal, electrical, or anything at heights. A typical short-job list covers:

Our COI requirements by trade pages are a good starting point for tiers, and you should confirm the right limits with your broker.

A same-day process

  1. Make "no certificate, no start" the rule, and say it when you book the job, not when the crew shows up.
  2. Email the vendor's insurance agent directly with your exact certificate holder name and additional insured wording. Most agencies can issue a certificate within hours, often the same day. Our COI request letter generator drafts the email.
  3. Check the basics before work starts: the named insured matches the vendor, the dates cover the job, the limits meet your list, and the right entity is the certificate holder. The free COI compliance checker takes a couple of minutes.
  4. Keep it on file even after the job ends. A claim can come months later, and you'll want the certificate that was current on the work dates.
  5. Reuse vendors you've already approved. A small list of pre-cleared vendors with current certificates removes most of the same-day scramble.

When a vendor can't produce a certificate

If a vendor has no insurance, or can't get proof before the job, the safest answer is to use someone else. Before you make any exception, talk with your broker and attorney about the risk, and write down who approved it and why. Don't accept a photo of an old certificate or a promise that coverage is "in the truck."

Key takeaways

Short jobs need a short process, not no process: a simple requirement list, a request to the agent when the job is booked, a two-minute check before work starts, and a certificate kept on file afterward. SubCover HQ handles requests, checks, and follow-ups for one-time vendors as well as your regular subs.

This guide is general information, not insurance or legal advice. Your contracts, insurance professional, and attorney determine what you should require.
