Devis

Devis is a term used in French-speaking business contexts to denote a document that outlines the estimated cost of goods or services proposed by a seller to a potential buyer. It serves to inform the client about the scope of work and the price, and it can become binding if accepted by the customer. In practice, a devis is usually issued after a request for quotation and before a sale or contract.

A typical devis includes several standard elements. It usually has a unique title or reference number, issue date, and the names and contact details of both parties. It provides a description of the proposed work or items, quantities if applicable, unit prices, any applicable taxes, and a total price. It also states the validity period, payment terms, delivery or completion timelines, and any conditions, exclusions, or assumptions. Some devises specify required site visits, dependencies, or approval steps, as well as procedures for changes, cancellations, or liability.

Legal effect and process. A devis is generally considered an offer rather than a binding contract. It becomes binding when the client accepts it, typically by signing the document or issuing a purchase order that references the devis. If the scope or price changes, a new devis or a formal amendment is usually required to maintain clarity and enforceability.

In translation and use elsewhere, the closest equivalents are “quote” or “estimate.” A devis differs from an invoice, which records payment for delivered goods or services, and from a contract, which formalizes the agreed terms in detail.
