Key Takeaways
Why Written Contracts Matter for Small Businesses
Verbal agreements feel straightforward in the moment — but they are notoriously difficult to enforce when a disagreement surfaces. Verbal agreements create legal headaches precisely because they leave critical terms open to interpretation. Written contracts create a shared, enforceable record of what both parties agreed to, reducing the likelihood of costly disputes and providing a clear path to resolution when conflicts do occur.
For small businesses in particular, legal exposure from missing or poorly drafted contracts is a common and avoidable risk. The following contracts represent the core agreements most small businesses should have reviewed, customized, and ready to use — not downloaded and used as-is from generic templates.
These Contracts Are Starting Points
The contracts described here represent common categories, not a definitive checklist for every business. The specific agreements a business needs depend on its industry, structure, size, and the nature of its client and vendor relationships. Contract requirements also vary by state. A licensed business attorney can help identify gaps and ensure that any agreement used is enforceable under applicable law.
The Core Contracts Small Businesses Need
Client Service Agreement
A client service agreement — sometimes called a service contract or master services agreement — defines the scope of work, payment terms, deadlines, and deliverables for every client engagement. Without one, disputes over what was promised, when it was due, or how much it should cost have no written reference point to fall back on.
This contract should specify payment schedules, late payment consequences, revision limits, and termination clauses. It also establishes what happens if the scope of work changes, protecting both the business and the client from misaligned expectations.
Without a service agreement, scope disputes have no written reference point to resolve them.
Non-Disclosure Agreement (NDA)
A non-disclosure agreement (NDA) protects confidential business information — trade secrets, proprietary processes, client lists, and unreleased product details — from being shared with unauthorized parties. Small businesses often overlook NDAs until after sensitive information has already been disclosed.
NDAs are relevant in multiple contexts: before sharing information with a potential partner, when onboarding contractors or vendors, and during merger or acquisition discussions. Mutual NDAs protect both parties; one-way NDAs protect only the disclosing party. The appropriate structure depends on the relationship.
NDAs are relevant long before a deal closes — they protect information during early conversations.
Employment or Contractor Agreement
Whether a business hires full-time employees or engages independent contractors, written agreements are essential. An employment agreement sets out compensation, job responsibilities, benefits, termination terms, and any non-compete or confidentiality provisions applicable to the role.
Contractor agreements serve a different purpose: they help establish the nature of the working relationship and reduce the risk of worker misclassification, which carries tax and labor law penalties. The IRS and Department of Labor each apply tests to determine whether a worker is an employee or an independent contractor — classification errors can be costly. For a broader view of employer obligations, see employment law basics that apply to most businesses.
Misclassifying a contractor as an employee — or vice versa — can trigger costly tax and labor penalties.
Partnership Agreement
Any business with more than one owner should have a partnership agreement or equivalent governance document, such as an operating agreement for an LLC. These agreements define each partner's ownership stake, decision-making authority, capital contributions, profit-sharing arrangements, and exit procedures.
Without this document, state default laws govern how disputes are resolved and how profits are split — and those defaults may not reflect what the partners actually intended. A well-structured agreement is especially critical when partners have unequal contributions or different roles. Setting up a partnership agreement that holds up covers the core provisions worth addressing before signing.
Without a partnership agreement, state default rules govern your business — not your intentions.
Vendor and Supplier Contract
Vendor contracts govern the terms under which a business purchases goods or services from third-party suppliers. These agreements should address pricing, delivery timelines, quality standards, liability for defective goods, and termination rights.
Small businesses often accept vendor-supplied contract templates without negotiation, which can leave them exposed to unfavorable liability clauses or automatic renewal terms. It is worth having legal counsel review any vendor agreement that involves significant spend or operational dependency. Note that some vendor contracts contain indemnification clauses that can affect your insurance obligations — contractual liability and insurance obligations explains how these provisions interact.
Vendor-supplied contract templates often contain terms that heavily favor the supplier — review carefully.
Terms and Conditions / Terms of Use
For businesses that operate a website, e-commerce platform, or software product, terms and conditions (T&Cs) establish the rules governing how users interact with the service. They typically address intellectual property ownership, acceptable use, limitation of liability, dispute resolution, and governing law.
T&Cs are not just legal formalities — they can limit a business's exposure to user-generated content claims or product liability disputes when drafted correctly. A privacy policy, often required under applicable state and federal law, should accompany T&Cs wherever personal data is collected. Businesses operating across state lines should be aware that legal requirements vary by jurisdiction.
Terms and conditions limit liability exposure and establish the legal rules governing your platform.
Review Contracts Before You Need Them
The best time to review a contract is before a dispute arises, not after. Establish a routine of having standard agreements reviewed by legal counsel when your business model changes, when you enter new markets, or when you significantly scale your workforce or vendor relationships. Proactive review is far less costly than litigation.
Putting Contracts to Work in Your Business
Having the right contracts in place is only part of the picture. Businesses also need to understand how those agreements interact with other operational realities — including financing arrangements and insurance coverage. If your business takes on debt, understanding the terms you are signing is equally important; business loan terminology you should know before signing any lending agreement. Similarly, some contracts create insurance obligations that are easy to miss — reviewing your business coverage needs alongside your contracts is sound risk management practice.
