Certificate of insurance for vendor and client contracts

Selling to larger companies means passing procurement review, and insurance is one of the checkboxes. Knowing the usual asks keeps a deal from stalling on paperwork.

What insurance do clients require from vendors?

Enterprise clients commonly require vendors to carry commercial general liability, professional liability or tech errors and omissions, cyber liability and workers compensation, and sometimes umbrella coverage, at limits stated in the contract. They ask for a certificate as proof and may require additional insured status and a waiver of subrogation.

Why procurement teams ask

A large client takes on risk every time it brings in a vendor. If your service fails or your systems are breached, the loss can land on them first, and insurance is the way they check that you can stand behind your work. The requirement is rarely personal. It is a standard step in vendor onboarding, and it often has to be completed before the first invoice is paid.

The lines that technology vendors usually need

For software, data and services companies, the most scrutinized coverage is not general liability. It is the policy that responds when your product or service causes a client financial loss, and the policy that responds when you suffer a data breach.

  • Technology errors and omissions or professional liability, for claims that your work failed or was negligent.
  • Cyber liability, for breach response costs and liability from a security incident.
  • Commercial general liability, for bodily injury and property damage.
  • Workers compensation, where you have employees on site or as required by state law.

Limits and endorsements

Contracts state minimum limits for each line, and larger clients often ask for more than a new company carries. If the required limit exceeds your current program, discuss it with your broker before you sign, since raising limits is a policy change and not something a certificate can fix. The same applies to endorsements such as additional insured status, which the client may require for general liability.

Keeping the certificate current

Client risk teams usually track expiration dates and will request updated certificates at renewal. Make a habit of asking your broker to send fresh certificates to major customers as soon as a renewal binds, so that a lapse on paper never interrupts a contract.

Vendor certificate questions

Can a customer require higher limits than my policy has?

Yes, a contract can require any limits it chooses. If your policy falls short, the limits must be increased on the policy before a compliant certificate can be issued.

Do I need tech E&O if I only provide consulting?

Many clients require professional liability or tech errors and omissions for consulting work, because general liability does not cover financial loss from advice or services.
