Document background
A Sales Addendum is a legal instrument used to modify or supplement an existing sales agreement without having to draft an entirely new contract. This document type is particularly relevant when parties need to update specific terms such as pricing, product specifications, delivery schedules, or service levels while keeping the main agreement intact. Under Irish law, such addenda must comply with the Sale of Goods and Supply of Services Act 1980 and related commercial legislation. The document is commonly used in business-to-business transactions where changing market conditions, business requirements, or commercial terms necessitate updates to existing agreements. It provides a streamlined approach to contract modification while ensuring legal certainty and continued enforceability of the original agreement's terms.
