A supplier is a person or company that provides goods or services to another business. They play a crucial role in the supply chain by ensuring that products are available for retailers or manufacturers. For example, a furniture supplier might provide chairs and tables to a home goods store, helping the store keep its inventory stocked for customers. Suppliers can vary in size, from small local businesses to large corporations. They often have contracts with their clients to deliver products on time and at agreed prices. A reliable supplier is essential for a business's success, as they help maintain smooth operations and customer satisfaction.
