购销 (gòuxiāo) is a compound noun meaning 'purchase and sale'—a standard business term referring collectively to the two core activities of buying goods from suppliers and selling them to customers. The first character 购 means 'to purchase' or 'to buy', while 销 means 'to sell' or 'to market'. Together, they form a concise, formal term commonly used in commerce, economics, and official documents to describe the full transaction cycle.

This word is typically found in institutional or professional contexts—not in casual speech—and often appears in phrases like 购销合同 (purchase and sales contract), 购销渠道 (distribution channels), or 购销差价 (markup). It emphasizes the interdependence of buying and selling as a unified commercial process, rather than treating them separately. While not limited to any specific industry, it’s especially frequent in discussions about wholesale trade, supply chain management, and state-owned enterprise operations.
