wholesale and retail definition is a useful concept in both traditional commerce and online selling, helping distinguish between business-to-business and business-to-consumer models. The wholesale and retail definition lies in transaction volume and pricing structure: wholesalers sell in bulk at lower prices to retailers, who then resell to end customers at marked-up prices. Understanding this distinction is critical for setting pricing strategies, negotiating supplier contracts, and managing inventory flow. Clear knowledge of wholesale and retail definition supports better business planning and market positioning.
