Two of these are filed by every company whatever it does. The rest depend on the trade. A reviewer reads each one before the company can answer a request of yours, which is a person doing a job rather than a checkbox somebody ticks on their own behalf.
Business registration is collected and read and gates nothing. It is worth saying plainly rather than letting it sit in a list that looks like a set of checks: holding it does not help a company answer you and lacking it does not stop them.
Two things this file never becomes are worth naming as well. It is not your purchase order system and it is not your contract file. It holds what a company carries, who read it, and the day it runs out.
Every document the rulebook holds
Read by a person
Auto liability

W-9
A signed W-9 carrying the company’s legal name and taxpayer number.
Workers’ compensation
The certificate covering the company’s own crew, with the date the policy runs out.
CPO certification
The card carries the date it expires.
Background check
The completed check, with the date it was run and the date it runs out.
Lifeguard certification
The certification carries the date it expires.
Pest control license
The state license to treat a building for termites, rodents and wood-destroying organisms, with the date it expires.
EPA 608 certification
The federal certification required to handle refrigerants under EPA Section 608. It carries no expiration date.
Electrical contractor license
The state license to perform electrical work as a company, with the date it expires.
Additional insured, said plainly
What the file holds is the certificate, the figure on each line, and the date the policy runs to.
Naming your agency as an additional insured is your carrier and their carrier extending a policy to cover you for what their work causes. It is agreed in your contract and evidenced by an endorsement form their agent issues. That form is not something this reads, checks or holds, and no sentence here will tell you it does. What is held, read and dated is the certificate. Everything past that stays where it already sits, between you, the company and its agent.
