A company or a location that offers a multitude of services to a client or a customer. The idea is to provide convenient and efficient service and also to create the opportunity for the company to sell more products to clients and customers.

For example, a bank may be able to offer you not only personal banking services and loans, but also investment advice, investment vehicles and insurance policies. Compared to visiting a separate institution for each area of need, the "one-stop shop" saves the consumer a lot of time and effort.
