Your COI was rejected. Here is how to read the rejection and fix it.

A rejected certificate is usually not an insurance problem. It is a paperwork problem, and four of the five common reasons are a one-day fix with a phone call to your agent.

This is written for the vendor side. If you are a property manager, it is also the list your rejection notices should be naming, because "non-compliant" tells a vendor nothing they can act on.

1. Additional insured endorsement missing or wrong scope

The most common rejection by a wide margin.

The certificate has the ADDL INSD box checked, but no endorsement form was attached, or the endorsement covers ongoing operations only.

What to ask your agent for: the additional insured endorsement forms, specifically CG 20 10 for ongoing operations and CG 20 37 for completed operations, or the carrier's equivalent. Send the endorsement pages, not just the certificate.

Why they want both: ongoing operations covers liability while you are working. Completed operations covers liability arising from the work after you finish. A roof you repaired in March that leaks in November is a completed operations claim, and property managers have learned that the hard way.

Cost: usually small. Turnaround: often same day.

2. Named insured does not match the contract

The certificate says one entity, the master vendor agreement says another.

This happens constantly with small trades, because you may be insured as "Lone Star Plumbing LLC" and contracting as "Lone Star Plumbing & Heating, Inc." Functionally the same company. Legally two persons, and at claim time the carrier reads the named insured.

What to do: decide which entity is the real contracting party, then make the certificate and the agreement agree. Your agent can add the other entity as an additional named insured if you genuinely operate as both.

Cost: usually nothing. Turnaround: a day.

3. Policy expires before the work would finish

The certificate is current today and the policy expires in six weeks, and the job runs three months.

What to do: if renewal is imminent, ask your agent for a certificate reflecting the renewal once bound. If it is not, say so, and most managers will clear you with a note to re-verify at renewal.

4. Primary and non-contributory or waiver of subrogation missing

Neither has a box on the ACORD form. They go in the description of operations field, and if your agent did not know to add them they are simply absent.

What to ask for: "please add primary and non-contributory wording and a blanket waiver of subrogation, and note them in the description of operations." Ask about the workers compensation policy separately, because a comp waiver is a different endorsement.

Cost: often nothing, sometimes a small premium. Turnaround: a day or two.

5. Coverage genuinely below requirement

The only one that is not paperwork.

If a manager requires $1M per occurrence and $2M aggregate and you carry $500K, no amount of form-shuffling fixes it. Your options are to buy up, or to lose the work.

Buying up is usually cheaper than people assume, and cheaper than the jobs you lose while deciding. IDCore places coverage through InsurePro at roughly $99 per vendor per year in 49 states, often the same day, which exists precisely because this rejection used to end the conversation.

Some rejections are about the wrong document entirely

Two that are not insurance at all and get bundled into a compliance rejection.

W-9 missing. Nobody can pay you without EIN or SSN and tax classification. Send it before you are asked twice.

License not current. Pool and some trades are licensed at the state or county level, and a lapsed license is a compliance failure a certificate review will never catch because it is a different document.

Do it once instead of every time

The reason this is worth getting right rather than fixing per manager: with IDCore, one vendor profile works across every property management company in the network. Upload once, stay credentialed everywhere, and renewal reminders come 30 days out so you are not the one watching the calendar.

The alternative is emailing certificates to every manager individually, tracking four renewal dates yourself, and scrambling for coverage when a gap is found mid-job. Which is what most vendors are doing, and it is why compliance feels like an obstacle rather than a one-time setup.

Ask for the requirement set in writing. What does yours actually say?
