Is an electronic signature legally enforceable?

Yes. Under the ESIGN Act (15 U.S.C. ch. 96) and UETA (adopted in most states), electronic signatures are legally equivalent to handwritten signatures for most transactions, provided intent, consent, attribution, and record retention requirements are met.

When is a paper signature or notarization necessary?

Certain exceptions such as wills, court orders, and some real estate filings may require handwritten notarization. Review state law and transaction type; remote notarization (RON) rules also vary by state.

What type of e-signature should we use?

A simple electronic signature with an audit trail suffices for many commercial contracts. Use PKI/digital signatures for higher non-repudiation requirements or regulated records (e.g., FDA 21 CFR Part 11).

How do we verify signer authority for a vendor?

Collect a printed name, title, and, when practical, an authorization document or certificate of incumbency. For corporate vendors, confirm signatory authority against formation documents or a board resolution.

What records should we retain after signing?

Retain the fully executed agreement, audit trail, and supporting tax forms for at least three years for IRS purposes (IRC §6501(a)); industry rules may require longer retention.

What if a vendor refuses to sign electronically?

You may accept a paper-signed agreement, but ensure the paper copy is retained and scanned into your records. Note that consumer-facing financial or health forms may require a consumer disclosure under 15 U.S.C. §7001(c).

What an E-Commerce Vendor Agreement Is and Why It Matters

An E-Commerce Vendor Agreement is a written contract that defines the commercial relationship between an online marketplace or platform and a third‑party vendor. It sets out the services or products to be supplied, pricing and payment terms, responsibilities for shipping and returns, data protection and intellectual property rights, dispute resolution, and termination mechanics. For U.S. transactions the agreement should also address tax documentation, compliance with ESIGN and UETA where electronic execution is used, and whether any notarization or witness acknowledgment is required for particular clauses.

Why a Clear Vendor Agreement Reduces Risk

A well-drafted E-Commerce Vendor Agreement clarifies each party’s obligations, limits liability exposure, and establishes dispute resolution and payment processes to reduce operational friction and legal uncertainty.

Who Typically Prepares and Signs This Agreement

Platform operators, procurement and vendor management teams, and legal counsel commonly prepare or review vendor agreements before onboarding third-party sellers.

Marketplace operators and vendor managers responsible for onboarding and compliance
Small business owners and individual sellers supplying products or services online
Corporate legal and finance teams approving commercial and tax provisions

Core Sections to Include in a Professional Agreement

A complete E-Commerce Vendor Agreement groups expectations into logical sections to reduce ambiguity and support operational enforcement across listings, payments, returns, data handling, and disputes.

Parties

Identify the contracting legal entities and include DBA names, state of formation, and primary contact details to ensure contractual attribution and tax reporting align.

Scope

Define permitted products/services, listing responsibilities, pricing controls, approved territories, and any prohibited items or category restrictions to prevent downstream disputes.

Payment Terms

Specify payment schedule, invoice timing, chargebacks, fees retained by the platform, currency, and any required tax documentation such as W-9 or IRS forms.

Term & Termination

State the initial term, renewal rules, termination for convenience or cause, cure periods, and post-termination obligations such as inventory removal or settlement.

IP & Data

Allocate intellectual property rights, license grants for product content and images, and data handling obligations including consumer personal data and analytics feeds.

Liability & Indemnity

Limit liability, set indemnity scope for third-party claims, and clarify insurance requirements and caps on recoverable damages where permitted by law.
