Every startup interacts with two key categories of agreements: commercial contracts (with customers, partners, or resellers) and vendor contracts (with suppliers, service providers, or consultants). These agreements drive revenue on the one hand and support operations on the other. For a startup, getting them right is critical to protecting cash flow, brand reputation, and intellectual property.
Commercial Agreements
Commercial contracts govern how your company sells products or services to customers, or enters partnerships with other businesses. They are often the most visible and high-stakes agreements for a startup.
Common types of commercial agreements:
- Sales contracts – direct sales to customers.
- Licensing agreements – granting others rights to use your IP.
- Reseller or distribution agreements – authorizing third parties to sell your product.
- Partnership agreements – co-marketing, co-development, or joint ventures.
Key clauses to review carefully:
- Scope of services or products – what exactly is being provided.
- Payment terms – timing, method, late fees, and refund policies.
- Intellectual property – whether rights are licensed or assigned, and limitations on use.
- Warranties and liability – what guarantees are made, and what risks are capped.
- Termination – how either party can exit the relationship.
Founder tip: Avoid signing one-sided agreements drafted by large corporate customers without negotiation. While leverage may be limited, pushing for balanced terms on liability and IP ownership can prevent serious problems later.
Vendor Agreements
Startups rely heavily on vendors - from SaaS providers and marketing agencies to contract developers and manufacturers. Vendor contracts determine how you obtain essential services and technology.
Common pitfalls in vendor contracts:
- Hidden fees: Automatic renewals, price increases, or unclear billing practices.
- IP ownership gaps: Contractors may retain rights to work product unless explicitly assigned.
- Termination traps: Long lock-in periods or stiff penalties for early termination.
- Data security risks: Weak confidentiality or data protection provisions.
Best practices when reviewing vendor contracts:
- Ensure deliverables and responsibilities are clearly defined.
- Cap liability and require vendors to carry appropriate insurance.
- Confirm that all intellectual property created is assigned to your company.
- Negotiate termination rights for flexibility as the business grows.
Why These Agreements Matter
Commercial and vendor contracts directly affect two of the most important aspects of a startup: revenue and operations. Poorly drafted commercial agreements can lead to disputes with customers or lost revenue. Weak vendor agreements can result in IP leakage, unexpected costs, or operational disruptions.
Startups should view every contract not as boilerplate, but as an opportunity to define expectations, allocate risks, and protect the company.
The Takeaway
Commercial and vendor agreements are the lifeblood of a startup’s external relationships. By carefully reviewing key clauses, negotiating where possible, and ensuring clarity around scope, payment, and IP, founders can avoid common pitfalls and build stronger, more reliable partnerships.
