39 Types of Business Contracts Every Organization Should Know About

As Gordon Thompson, Executive Vice President, Siron explains:

“Contracts are no longer just a document at the end of a long negotiation. Contracts are the starting point for long-term B2B relationships that are the lifeblood of any organization.”

The following sections outline the most common types of business contracts used by organizations across industries.

1. Purchase Order

A Purchase Order (PO) is a commercial document issued by a buyer to a supplier that authorizes the purchase of goods or services. It specifies quantities, pricing, delivery schedules, payment terms, and other purchasing conditions. Once accepted by the supplier, a purchase order often becomes a legally binding agreement that helps reduce procurement disputes.

2. Order Form

An Order Form documents the products or services a customer agrees to purchase under an existing contract or master agreement. It typically captures pricing, subscription terms, quantities, renewal details, and other transaction-specific information without requiring parties to renegotiate the broader contractual relationship.

3. Statement of Work (SOW)

A Statement of Work (SOW) defines the specific scope, deliverables, milestones, timelines, responsibilities, and acceptance criteria for a project or service engagement. It is commonly used alongside a Master Service Agreement (MSA) to govern individual projects while relying on the broader commercial terms established in the master agreement.

4. Non-Compete Agreement

A Non-Compete Agreement restricts an employee, contractor, or business partner from competing with an organization for a specified period, geographic area, or market after the relationship ends. Because enforceability varies by jurisdiction, these agreements should be carefully drafted to comply with applicable laws.

5. Security and Privacy Addendum

A Security and Privacy Addendum establishes the technical, organizational, and compliance obligations required to protect confidential information and personal data. Organizations commonly include these addenda in technology and SaaS agreements to address cybersecurity requirements and privacy regulations such as GDPR or other applicable laws.

6.  Request for Proposal (RFP)

A Request for Proposal (RFP) is a procurement document that invites suppliers to submit detailed proposals for a product, service, or project. While not a contract itself, an RFP forms the foundation for vendor evaluation and often leads to subsequent commercial agreements with the selected supplier.

7. Terms of Use Agreement

A Terms of Use Agreement establishes the rules governing how users may access and use a website, software application, or digital platform. It outlines acceptable use, intellectual property rights, prohibited activities, limitations of liability, and dispute resolution procedures to protect both the service provider and its users.

8. Warranty Agreement

A Warranty Agreement defines the quality standards, performance commitments, and remedies available if a product or service fails to meet agreed specifications. These agreements help establish customer expectations while reducing disputes over defects, repairs, replacements, or service performance.

9. Security Agreement

A Security Agreement grants a lender or creditor a legal interest in specified collateral to secure repayment of a loan or other financial obligation. If the borrower defaults, the agreement provides the lender with defined rights to recover or enforce the pledged assets in accordance with applicable law.

10. Memorandum of Understanding (MOU)

A Memorandum of Understanding (MOU) records the parties’ intent to collaborate before entering into a formal contract. Although many MOUs are non-binding, they establish shared objectives, responsibilities, and commercial expectations that often serve as the foundation for future legally enforceable agreements.

11. Amendment Agreement

An Amendment Agreement formally modifies an existing contract without replacing the original agreement. Organizations use amendments to update pricing, extend timelines, revise deliverables, change responsibilities, or introduce new contractual terms while preserving the remainder of the original contract.

12. Influencer Agreement

An Influencer Agreement governs the relationship between a brand and a content creator. It defines campaign deliverables, content ownership, payment terms, disclosure obligations, usage rights, performance expectations, and termination provisions to ensure both parties clearly understand their responsibilities.

13. Sponsorship Agreement

A Sponsorship Agreement outlines the commercial relationship between a sponsor and an individual, organization, or event. It specifies financial contributions, promotional rights, branding obligations, exclusivity provisions, deliverables, and performance expectations, ensuring both parties receive the agreed value from the sponsorship arrangement.

14. Fixed-Price Contract

A fixed-price contract sets a total cost for the project or service upfront, regardless of actual expenses incurred. This model transfers most cost risk to the provider and is commonly used when scope and requirements are clearly defined, making budgeting and financial forecasting more predictable.

15. Cost-Plus Contract

A cost-plus contract reimburses the provider for actual project costs and adds a predetermined fee or margin. It is often used when project scope is uncertain or evolving, ensuring transparency while allowing flexibility in complex or research-driven engagements.

17. Unit Price Contract

A unit price contract sets a fixed rate per unit of work, product, or service delivered. Payments are calculated based on the number of units completed, making this model suitable for construction, manufacturing, and volume-based delivery arrangements.

18. Indemnity Agreement

An indemnity agreement allocates liability between parties by requiring one party to compensate the other for specific losses, damages, or claims. These agreements are commonly used to manage legal and financial exposure in high-risk transactions.

19. Employment Contract

20. Service Contract / Master Service Agreement (MSA)

An MSA establishes the governing terms for an ongoing services relationship, while individual Statements of Work (SOWs) define specific deliverables, pricing, and timelines. This structure simplifies repeat engagements and ensures consistent contractual governance.

21. Sales Contract / Bill of Sale

A sales contract formalizes the exchange of goods or services for payment by defining pricing, delivery terms, warranties, and payment obligations. It provides legal clarity and protects both buyer and seller in commercial transactions.

25. Lease Contract

A lease contract governs the use of property, equipment, or assets for a specified period in exchange for payment. It defines rent terms, maintenance responsibilities, and usage restrictions for both lessor and lessee.

30. Franchise Agreement

A settlement agreement resolves disputes by defining payment terms, releases, confidentiality, and future obligations. It allows parties to avoid litigation and close legal matters in a controlled and enforceable manner.
