Vendor Agreement Law in the United States

A vendor agreement is a contract between a business and a supplier for goods or services. For most private agreements, you're free to negotiate terms. However, federal law requires specific clauses if you're dealing with consumers electronically, handling trade secrets, contracting with the government, or working in healthcare or financial services.

Does a vendor agreement have to be in writing?

A written contract is required for the sale of goods priced at $500 or more (U.C.C. § 2-201).

What should be included in a vendor agreement?

While most commercial terms are negotiable, federal law mandates specific clauses in certain situations.

What can't I include in a vendor agreement?

Federal law voids or restricts specific terms in certain contexts.

The Consumer Review Fairness Act voids provisions in form contracts that prohibit or restrict reviews, impose penalties for them, or transfer intellectual property rights in review content beyond a non-exclusive license (15 U.S.C. § 45b(b)(1)). Offering a contract containing such void provisions is itself unlawful (15 U.S.C. § 45b(c)).

Is my vendor agreement legally binding?

Basic Contract Formation

Standard contract principles apply: mutual assent, consideration, and lawful purpose. Electronic contracts are valid if the electronic agent's action is legally attributable to the person to be bound (15 U.S.C. § 7001(h)).

Statute of Frauds for Goods Contracts

Under U.C.C. § 2-201, contracts for the sale of goods priced at $500 or more require a signed record sufficient to indicate a contract was made. Between merchants, a confirming record satisfies the requirement unless objected to within ten days (U.C.C. § 2-201(2)). Exceptions apply for specially manufactured goods, judicial admissions, and part performance (U.C.C. § 2-201(3)). Electronic records with a signature block satisfy this requirement (Princeton Industrial Products, Inc. v. Precision Metals Corp., 87 U.C.C. Rep. Serv. 2d (West) 460, 120 F. Supp. 3d 812 (N.D. Ill. 2015)).

Predominant Purpose Test for Mixed Transactions

For contracts involving both goods and services, courts apply a predominant purpose test to determine if U.C.C. Article 2 applies. Factors include contract language, the supplier's business, the reason for the contract, and relative costs. The party seeking U.C.C. application bears the burden of proof (Max E. Pass, Sr. v. Shelby Aviation, Inc., No. W1999-00018-COA-R9-CV (Tenn. Ct. App. Apr. 13, 2000)).

Warranty Disclaimers

To disclaim the implied warranty of merchantability, the disclaimer must mention "merchantability" and be conspicuous. To disclaim fitness for a particular purpose, the disclaimer must be in writing and conspicuous. "Conspicuous" means presented so a reasonable person ought to have noticed it (U.C.C. § 1-201(b)(10)).

Indemnification Clarity

Under the express negligence rule, a contract must explicitly state intent to indemnify a party for its own negligence. General language is insufficient (Fina, Inc. v. ARCO, No. 98-41021 (5th Cir. Jan. 4, 2000)). Proportional indemnity—limiting indemnity to the indemnitor's allocable share while disclaiming liability for the indemnitee's own negligence—satisfies this rule (S&B Engineers & Constructors, Ltd. v. Scallon Controls, Inc., Texas Supreme Court).

Common Pitfalls

Inadequate trade secret immunity notice. Failure to include the 18 U.S.C. § 1833(b) notice eliminates rights to exemplary damages and attorney's fees in DTSA actions against employees.

Overbroad indemnification. Clauses purporting to cover a party's own negligence without explicit, conspicuous language are unenforceable in jurisdictions applying the express negligence rule.

Inconspicuous warranty disclaimers. Disclaimers buried in fine print or lacking the word "merchantability" fail to exclude implied warranties.

Consumer review restrictions. Even standard form contract language restricting reviews or imposing penalties for negative feedback is void and unlawful under federal law.

Unilateral change provisions in government contracts. GSAM 552.232-78 automatically deems such provisions unenforceable; bilateral modification is required.

Liquidated damages as penalties. Clauses stipulating damages without a reasonable relationship to anticipated harm risk being struck as unenforceable penalties (U.C.C. § 2-718).

"As is" sales with written warranties. Offering a written warranty while disclaiming implied warranties through "as is" language violates the Magnuson-Moss Warranty Act.
