Every business relationship should start with a written contract. Whether you are hiring a freelancer, renting a property, engaging a consultant, or protecting confidential information, the right contract eliminates ambiguity and gives both parties enforceable expectations.
This guide covers the most common contract types, what each one needs to include, and how to create customized, jurisdiction-aware contracts without spending hours on formatting and legal research.
The 5 Contracts Every Business Needs
1. Non-Disclosure Agreement (NDA)
What it does: Protects confidential information shared between parties.
When you need it:
- Before sharing business plans, financials, or product roadmaps with potential partners or investors
- When hiring contractors or employees who will access proprietary systems
- During merger or acquisition discussions
- Before licensing negotiations
Essential clauses:
- Definition of confidential information (specific categories, not generic language)
- Obligations of the receiving party
- Standard exclusions (public information, independently developed, etc.)
- Term and survival period
- Governing law and remedies

What Every Contract Must Include
Regardless of type, every enforceable contract needs these foundational elements:
Parties
Full legal names of all parties. For businesses, include the legal entity name (not just a trade name) and the state or country of incorporation.
Recitals (Background)
A brief section explaining why the parties are entering the agreement. Recitals are not legally binding on their own, but they provide context that courts use to interpret ambiguous terms.
Definitions
Define any terms that could be misinterpreted. "Confidential Information," "Deliverables," "Services," "Work Product" — these should all have precise definitions, not assumed meanings.
Obligations
What each party must do. This is the core of the contract and should be specific enough that a third party (a judge, an arbitrator) could determine whether obligations were met.
Payment
How much, when, how, and what happens if payment is late. Include the fee structure, invoice timing, payment method, late fees, and suspension-of-work rights for non-payment.
Term and Termination
When the contract starts, when it ends, and how either party can exit. Cover termination for convenience (with notice period) and termination for cause (material breach, non-payment).
Governing Law
Which jurisdiction's laws apply. This is critical for cross-state and cross-border agreements where different laws could lead to different outcomes.
Signatures
Signed by authorized representatives of each party with printed names, titles, and dates. Electronic signatures (DocuSign, Adobe Sign, or similar) are legally valid in most jurisdictions under the ESIGN Act and UETA.
Common Contract Mistakes to Avoid
Using templates without customization. A template is a starting point. Every clause should be reviewed and adjusted for your specific situation, jurisdiction, and counterparty.
Vague scope language. "Consulting services as needed" is not a scope. Specify what is included, what is excluded, and the process for adding scope.
Missing termination clause. Without a clear exit strategy, either party can be trapped in a contract that no longer serves them.
No governing law. If a dispute arises, which state's law applies? Without this clause, you could end up in an unfavorable jurisdiction.
Oral modifications. Include a clause requiring all modifications to be in writing and signed by both parties. This prevents "but we agreed to change that on a phone call" disputes.
Ignoring state-specific requirements. Employment contracts, lease agreements, and non-compete clauses all have state-specific rules that override generic template language. Using a jurisdiction-aware contract builder prevents this.
