A concierge service is unique in that it can be defined in different ways. Depending on the level and types of services provided, a concierge service can be classified as an errand or personal assistance service. Typically, this type of service limits itself to specific services, like personal shopping or running errands as needed.
By contrast, a concierge service outsourced by a corporation or residential property takes on different and often additional responsibilities than would be expected by an errand service, such as event coordination. Nonetheless, a privately-owned concierge service is nothing short of a one-stop shop to assist people with practically any and everything.
