Certificate of Insurance for Vendors in Texas
Short answer: a vendor certificate of insurance reports coverage already provided by the policy. In Texas, it cannot create a higher limit, a new coverage line, or additional insured rights. Compare the customer's written insurance requirements with your policies and endorsements first; then request a certificate that accurately reports the result.
That sequence explains a common vendor onboarding delay. A supplier uploads a certificate, the customer asks for different wording, and the agent must check whether the underlying policy supports it. Texas Insurance Code Chapter 1811 restricts what a certificate may say; changing the document alone cannot change insurance coverage.
This guide covers how to review a vendor packet, what a Texas certificate can report, and how to investigate a portal rejection without assuming every customer uses the same requirements.
What a vendor onboarding packet usually asks for
Requirements vary enormously by customer size and industry, but the shape is consistent.
Commercial general liability. Many customers ask for it, sometimes with $1,000,000 per occurrence and $2,000,000 aggregate limits. Those figures are examples of contract terms, not statewide minimums. Check products and completed operations where the work involves goods or finished work.
Commercial auto. A customer may require it when vendors drive, deliver, or haul. Read the exact limit and whether the contract asks for owned, hired, or non-owned vehicles; a personal auto policy should not be assumed to satisfy a business requirement.
Workers compensation and employers liability. TDI explains that most Texas private employers may choose whether to carry workers compensation, but a particular contract can require it. A nonsubscriber also has state notice and reporting duties. Check the customer's exact requirement and the Texas workers comp guide.
Umbrella or excess liability. Usually stated as a total: $2,000,000, $5,000,000, or more, satisfied by primary plus excess.
Professional liability. For consultants, designers, engineers, IT vendors, staffing firms, and anyone whose deliverable is advice or a work product rather than a physical thing.
Cyber liability. Some customers require it when vendors access data, systems, or payment information.
Crime or fidelity bonding. For vendors with access to cash, inventory, or customer premises.
The customer may also ask for policy terms that need endorsement review:
- Additional insured status for the customer, and frequently its parents, subsidiaries, affiliates, officers, and employees.
- Waiver of subrogation in the customer's favor.
- Primary and non-contributory wording, meaning your policy pays first and their policy does not contribute.
- Notice of cancellation, often stated as 30 days.
- Severability or cross-liability language.
Those terms must be supported by the actual policy or applicable endorsements. A certificate cannot add them on its own.
What Texas law lets a certificate say
Chapter 1811 of the Texas Insurance Code governs property and casualty certificates for risks located in Texas. The Texas Department of Insurance guidance is unusually specific, and it is worth knowing the actual rules rather than arguing about them with a procurement analyst.
A certificate cannot say more than the policy. Section 1811.051. This is the governing principle and everything else follows from it.
Blanket endorsements are described, not converted. If the policy carries a blanket additional insured endorsement, the certificate may state that the blanket endorsement exists. It may not name the holder as an additional insured on that basis. The same principle applies to a blanket waiver of subrogation. If a customer requires its name on the certificate, ask whether it will accept the blanket endorsement itself or whether a scheduled endorsement is available and needed.
A certificate cannot reference another contract's insurance requirements. Section 1811.154. A job number or contract number for identification is fine. Language like "coverage is provided in accordance with the terms of contract number X" is not.
Notice of cancellation follows the policy. Section 1811.155 allows a legal right to notice only where the person is named in the policy or an endorsement and the policy, endorsement, or Texas law requires that notice. A certificate cannot alter those terms. So a blanket demand for 30 days notice on the certificate does not create 30 days notice.
Supplemental questionnaires and affidavits are not substitutes. Where a form falls within the statutory definition of a certificate, Chapter 1811 applies. TDI says an agent may show relevant policy language or provide a copy of the policy or endorsements instead. The customer still decides whether that evidence satisfies its contract.
The certificate holder box cannot manufacture rights. Section 1811.153. Listing a customer's officers, employees, subsidiaries, affiliates, and assigns in the holder box does not confer additional insured status on any of them.
Texas risk means a Texas-approved form. Regardless of where the certificate holder sits, a certificate for a risk located in Texas must use a form filed with and approved by TDI. Standard ACORD, AAIS, and ISO forms are deemed approved on filing. Where the risk is in another state and the holder is in that state, the Texas requirement does not apply.
False certificate wording has consequences. Chapter 1811 provides enforcement and penalty mechanisms that can apply to people who issue or demand a certificate that violates the law. Ask the agent to resolve a disputed request using the policy and TDI guidance.
Why portals reject certificates
Vendor portals apply the customer's review rules, sometimes with automated checks. Ask for the rejection reason and compare it with the written insurance exhibit before revising anything.
Entity name mismatch. The customer may expect a particular legal entity and address. Compare the certificate holder information with the contract and portal instructions.
Limit below requirement. Often because the contract states a total that requires an umbrella and the vendor only carries primary.
Missing endorsement evidence. Per TDI's guidance, an additional insured or waiver box should be checked when an endorsement names the holder. If the policy has only blanket endorsements, describe those accurately and ask whether the reviewer accepts a copy of the endorsement.
Expired policy or renewal concern. A current annual policy may be acceptable for a longer contract if the customer requires updated evidence at renewal. Ask how the portal handles renewal certificates rather than assuming the current policy must run for the full contract term.
Wrong holder address. Portals frequently match the remit-to or legal notice address from the contract, not the site address.
Description box problems. If a customer requests wording that imports the contract's insurance requirements into the certificate, Section 1811.154 prohibits that. A job or contract number can identify the work without asserting that the policy fulfills every contract term.
Missing aggregate breakouts. Some portals want products and completed operations aggregate stated separately from general aggregate.
Workers compensation gap. If the contract requires this coverage, a nonsubscriber explanation may not satisfy it. Ask the customer whether it accepts an alternative before signing.
The sequence that works
Following this order reduces avoidable revisions, though endorsements and customer reviews still have their own timelines.
Step 1. Get the insurance exhibit before you sign. Request the insurance requirements attached to the master service agreement or purchase order, including any referenced amendments. A summary email may omit conditions that affect coverage.
Step 2. Send the exhibit to your agent, not the certificate request. The agent's job at this stage is to compare the exhibit line by line against your policies and tell you what is missing. That comparison is the deliverable, not the certificate.
Step 3. Resolve what is missing. A limit increase, new coverage, or endorsement may need a carrier quote and approval. Ask what the insurer can provide, at what cost, and when it becomes effective before promising compliance to the customer.
Step 4. Confirm the exact legal entity names. Yours and the customer's, spelled as the contract spells them.
Step 5. Then request the certificate. Once coverage is confirmed, provide the holder name, address, requirements, and deadline through Argo's COI request page. The same-day certificate guide explains why a request involving existing coverage can differ from a carrier endorsement request.
Step 6. Calendar the renewal. Ask when the customer needs updated evidence, and set your own reminder before the policy expires. Portal consequences depend on the customer's process.
The endorsement questions worth asking
When your agent reviews the exhibit, these are the specifics that decide whether the certificate clears.
Is the additional insured endorsement blanket or scheduled? A blanket endorsement may apply when its stated conditions are met. Under TDI's certificate guidance, the certificate cannot name the holder as additional insured based only on the blanket form. Ask whether the customer accepts the endorsement itself; if it requires a named endorsement, ask the insurer whether one is available.
Does the additional insured endorsement include completed operations? Ongoing and completed operations can be treated differently. Check both the endorsement and the contract for how long the customer expects protection after work ends.
Is primary and non-contributory wording present? Check the policy and endorsements rather than assuming a standard general liability form provides the wording the customer requested.
Is the waiver of subrogation on every line the contract names? Waivers on general liability, auto, and workers compensation are separate endorsements on separate policies. A contract requiring all three and a certificate showing one fails.
Does anything in the policy conflict with the work? Ask about operation-specific exclusions or conditions, such as residential construction, height, subcontracted work, or professional services, where relevant to the job.
Do the limits survive other jobs? Aggregates are annual and shared across every customer you serve. Satisfying a $2,000,000 aggregate for one customer does not reserve that aggregate for them.
The contract-type requirements guide covers how these demands differ across construction, service, and supply agreements, and the additional insured versus certificate holder explainer covers why the distinction matters more than vendors expect.
A vendor onboarding checklist
- Do you have the written insurance exhibit, not a summary?
- Does every required limit already exist, including any umbrella needed to reach a stated total?
- Is additional insured status endorsed, and does it include completed operations if required?
- Is the additional insured endorsement blanket or scheduled, and does the customer require being named?
- Is waiver of subrogation endorsed on each line the contract names?
- Is primary and non-contributory endorsed?
- Do you carry workers compensation, or do you have a documented nonsubscriber position and a plan for how procurement will treat it?
- Is the policy current, and when must you send updated evidence at renewal?
- Is the customer's exact legal entity name, in the exact form the contract uses, in hand?
- Does any exclusion in your policy conflict with the scope of work?
- Is your annual aggregate realistic across all the customers relying on it?
- Have you resolved any coverage gaps before asking the certificate to report compliance?
Three vendors, three different problems
A janitorial company onboarding with a property management firm. The sample exhibit asks for general liability, auto, workers compensation, and crime coverage because crews hold keys. A Texas nonsubscriber should ask whether the customer requires a workers compensation policy and whether the other limits and endorsements are available before accepting the contract.
An IT consultancy onboarding with a manufacturer. The customer may focus on professional liability for the work product and cyber coverage for system access, in addition to general liability. Check the requested limits and exclusions against the actual services.
A specialty fabricator supplying parts to a contractor. Products and completed operations, the scope of additional insured coverage, and the annual aggregate may matter after delivery. Ask how a claim from one customer could affect the remaining aggregate and whether any policy condition applies to subcontracted work.
Each example starts with the same step: read the written requirement and compare it with the policy before producing evidence.
Frequently asked questions
What does a vendor certificate of insurance usually have to show?
The customer's written requirements control what it asks to see. A packet may call for general liability, auto, workers compensation, umbrella, professional liability, or cyber coverage, plus stated limits and endorsement evidence. The certificate must accurately report the policy and applicable endorsements; it cannot add missing coverage.
Can my agent just add the customer as an additional insured on the certificate?
No. The policy must provide additional insured status under its terms or an endorsement. Under TDI's certificate guidance, a certificate may describe an existing blanket endorsement, but it may not name the holder as an additional insured based only on that blanket endorsement. Ask the customer whether it accepts the endorsement itself or requires a scheduled endorsement.
Why did the vendor portal reject my certificate?
Compare the rejection notice with the written insurance exhibit. Check the legal entity and holder details, limits, coverage lines, endorsement evidence, policy dates, and upload instructions. Ask the reviewer which requirement failed before requesting different certificate wording.
Can a customer require my agent to complete a vendor insurance questionnaire or affidavit?
TDI says a supplemental questionnaire or insurance affidavit that meets Chapter 1811's definition of a certificate cannot replace an approved certificate. The agent can provide relevant policy language or copies of the policy or endorsements when appropriate. Ask the customer what evidence it will accept.
Does a certificate give my customer the right to 30 days notice of cancellation?
No, unless the policy or endorsement already gives that person the applicable right to notice, or Texas law requires it. A certificate cannot change the policy's notice terms. Have the agent check the actual notice provision before promising a particular period.
My customer is out of state but the work is in Texas. Which certificate form applies?
For a risk located in Texas, TDI says the certificate must use a form filed with and approved by the department, regardless of where the holder is located. If the risk and holder are in another state, ask the agent which state's form rules apply.
Where Argo fits
Argo Insurance can review a Texas vendor's insurance exhibit against available policy information and identify questions about limits, coverage lines, and endorsements. Send the requirements through the appropriate agency intake process before the customer deadline.
Start with a COI request if you have an active policy, or a business insurance review if you need to compare coverage with a new contract. The agent can explain what the policy supports and which requests need carrier action.
Coverage descriptions here are general. Limits, exclusions, endorsements, and eligibility vary by carrier, and the policy issued controls.
