At an institutional account, vendor approval is a gated process. Know how each gate works and you clear them instead of stalling at them.
A RocketLevel playbook for restoration owners, ops, and commercial sales leads, backed by decades of experience in the trade. About a 10-minute read.
Plenty of contractors picture vendor approval as a moment: a property manager likes you, shakes your hand, and adds you to the list. At a small owner, it can work that way. At a hospital system, a national property manager, a real estate investment trust (REIT), or a large industrial site, approval is a process, run by people you may never meet, enforced by software, and gated at several points before a human ever weighs your reputation.
This is where good contractors stall. They build a real relationship with one champion, assume that is the approval, and then go quiet when a COI form, a prequalification invite, or a procurement step lands in the inbox. The work feels stuck for reasons no one explains, and more charm will not move it. Knowing how the process works will.
Insurance, safety scores, prequalification status, and procurement rules each run on their own track, and any one of them can hold you without anyone telling you why. The four gates below show how each one works.
Gate one: the certificate of insurance, and the endorsements that actually matter
Everyone knows commercial decision makers want a certificate of insurance (COI). What trips contractors up is that the decision maker is checking more than whether you have insurance: they want your policy endorsed to protect them in the specific ways their contract requires. A COI that lists healthy limits but is missing the required endorsements gets bounced back, and the clock keeps running.
Three endorsements show up again and again on commercial requirements:
- Additional insured. The client (and often the property owner and the manager) wants to be named as an additional insured on your general liability policy, usually for both ongoing and completed operations. This extends your coverage to defend them if a claim arises from your work. Decision makers frequently specify the Insurance Services Office (ISO) endorsement forms by name and ask for a copy of the endorsement page attached to the certificate, not just a checkbox on the COI.
- Primary and non-contributory. This says your policy pays first and does not ask the client's own insurance to chip in. Without it, your carrier can try to share the loss with theirs, which is exactly what the client wrote the requirement to prevent.
- Waiver of subrogation. This stops your insurer from turning around and suing the client to recover what it paid out on a claim tied to your work. Decision makers require it so that hiring you does not create a new way for them to get billed. Two things about it bite contractors. Whether your policy honors a waiver is set by its own wording, so have your agent confirm it, and plan on agreeing to it in writing before any loss occurs, because a waiver you promise after something has already happened may be worth nothing to the client and does not fix the contract breach. And a waiver on the workers' compensation policy is a separate endorsement from the one on general liability, often carries its own premium charge, and whether it is restricted or unavailable is set by your state's workers' compensation rules, so look up yours. Send your agent the client's exact wording and get confirmation of what was actually endorsed on which policy.
A few practical points that save weeks:
- Watch the limits. The most common ask in commercial Master Service Agreements (MSAs) and vendor packets is general liability around $1M per occurrence and $2M aggregate, with auto liability, workers' compensation at statutory limits, and an umbrella or excess policy stacked on top. Larger institutions often ask for $2M per occurrence and higher umbrellas. The exact numbers are the decision maker's call, so read each requirement rather than assuming your standard policy clears it.
- "Available upon request" is not coverage. A certificate that says a waiver or additional-insured status "may apply" or is "available upon request" reads, to a risk reviewer, as protection you do not currently carry. The endorsement has to actually be on the policy.
- A lapsed COI auto-suspends you. This is the part contractors underestimate. In most modern vendor systems, the day your certificate expires, your status flips and open work orders can be hard-blocked until a current certificate is uploaded and verified. No one calls to warn you. You simply stop being eligible, often in the middle of an active relationship, and have to climb back to current before work resumes.
- The certificate itself is not coverage, and it does not create any. This is the misunderstanding that costs contractors the most. A certificate of insurance is an informational summary issued for convenience. Standard ACORD certificate forms say so on their face (ACORD 25), in the notice stating that the certificate confers no rights on the holder and does not amend, extend, or alter the coverage the policies provide. If the endorsement is not on the policy, the client is not an additional insured, no matter what the certificate says or who filled it out. That cuts both ways. It means a clean-looking certificate will not save you in a claim, and it means the client's risk reviewer is right to demand the endorsement pages. Ask your agent for copies of the actual endorsements and keep them with the certificate.

⚠️
Reviewed October 2026. Policy forms and state insurance rules vary. Use this page to know what to ask, then confirm with your insurance agent or a construction attorney before you rely on it.
Do not sign a contract that promises a waiver of subrogation until your carrier has issued the endorsement. If the endorsement is not in force on the day of the loss, the gap lands on your balance sheet, and your policy may limit what you can waive without the insurer's consent. Before your name goes on it, run it past a lawyer who handles construction work in your state.
