A supplier is an entity—such as a company or organization—that provides goods or services to another party. In the context of procurement, “the supplier” is specifically the entity that submits a bid, offers a quote, or enters into a contract to supply the required goods, services, or works.
Within procurement frameworks, the term supplier is synonymous with other roles such as vendor, economic operator, bidder (when competing in a tender), and contractor (once selected and engaged under a contract). These terms reflect the supplier’s evolving relationship with the contracting authority throughout the procurement lifecycle.
Practically speaking, the supplier plays a central role in public procurement—from shaping the procurement competition to delivering the agreed products or services. Understanding the terminology helps all stakeholders correctly interpret contractual obligations, bidding opportunities, and responsibilities at each stage of the process.
