What Documents Does a Small Business Actually Need?

Most small business owners build their document library reactively: they create a document when someone asks for it, and discover gaps when something goes wrong. This reference covers the categories that matter from day one.

Formation and Governance

Operating agreement or bylaws
Articles of incorporation or organization
EIN confirmation letter
Business license (state and local, as applicable)
DBA registration if operating under a trade name

Contracts and Agreements

Standard client or customer agreement
Vendor agreements for recurring suppliers
Contractor agreements (separate from employee agreements)
Non-disclosure agreements
Partnership or shareholder agreements if applicable

Employment

Offer letters
Employee handbook
I-9 forms and W-4s for each employee
At-will or employment agreement (state-specific)
Confidentiality and IP assignment agreements

Insurance

General liability certificate
Workers compensation certificate (if required in your state)
Professional liability or E&O if applicable
D&O if you have a board

Compliance

Data privacy policy (required if you collect customer data)
Terms of service
Documented data retention and deletion policy

The list looks long but most documents are one-time setup. The ongoing work is tracking expiration dates on licenses, insurance, and contracts. That is the category where businesses most commonly fall behind.
