Can this extension be signed electronically?

Yes. Under the ESIGN Act (15 U.S.C. §7001) and UETA (adopted by most states), electronic signatures are legally valid for commercial contracts unless a statutory exception applies.

Is notarization required to enforce it?

Generally no for private contract amendments; however, notarization may be required if the extension modifies a deed, power of attorney, or state-specific instrument. Check state notary rules.

Who must sign the extension?

An authorized representative listed in the master agreement or with express delegated authority should sign; mismatched signatory authority can create enforceability disputes.

How do I update a signed extension?

Execute a subsequent amendment or mutual written agreement referencing the original extension; do not alter a signed PDF without a new executed amendment to preserve chain of custody.

How do I store executed copies?

Keep a tamper-evident signed PDF and audit trail in a centralized contract repository and maintain backups per retention requirements such as IRC §6501(a) for tax records.

Can I revoke or cancel the extension?

Revocation depends on terms in the extension and master agreement; typically requires mutual written agreement or termination language; consult legal counsel for material changes.

What the Business Services WMS Extension Is

The Business Services WMS Extension is a contract amendment that extends or revises an existing Warehouse Management Services (WMS) agreement to cover additional scope, time, fees, or technical integrations. It documents agreed changes—such as new modules, data exchange requirements, service levels, or support terms—without replacing the original master services agreement. The extension is typically signed by authorized representatives of both parties and attached to the primary contract as an exhibit or amendment, creating a clear record of the modified commercial and operational obligations.

Why Use a Formal WMS Extension

A written extension preserves the original contract while adding or updating terms for WMS software, hardware, implementation milestones, pricing, or integrations. It limits ambiguity about responsibilities, supports auditability, and establishes clear dates and acceptance criteria for new features or services.

Who Typically Prepares and Signs This Extension

Several roles participate in preparing and approving a WMS Extension; responsibilities vary by organization and contract value.

Logistics Managers — Draft scope changes, confirm operational impacts and timelines with operations and IT.
Procurement or Contracts Teams — Review commercial terms, pricing adjustments, and legal consistency with the master agreement.
IT/Integration Leads — Validate technical requirements, API changes, data mapping, and cutover plans.

Signatures should come from persons authorized under the master agreement (contract signatories or delegated officers) to ensure enforceability and prevent execution disputes.

Core Components to Include in a Professional Extension

A clear, well-structured extension reduces implementation friction and legal exposure. Include concise clauses covering scope, term, pricing, responsibilities, acceptance, and exhibits such as technical specs or change orders.

Scope of Work

Define added modules, features, integration points, and exact deliverables so both parties share the same expectations and acceptance criteria.

Term and Renewal

State the effective date, end date, any automatic renewals, and conditions for early termination tied to the extension specifically.

Pricing and Payment

List fees, billing schedule, invoicing details, and whether pricing is one-time, recurring, or milestone-based.

Service Levels

Include any new SLAs or modifications to uptime, response times, maintenance windows, and remedies for SLA failures.

Integration Details

Attach technical exhibits: API endpoints, data format, security requirements, and acceptance testing procedures.

Signatures and Authority

Identify authorized signatories, signature blocks for each party, and whether notarization or witness is required.
