business service provider (BSP) - Business Solution Provider
business service provider (BSP) is one of several categories of service provider in the business world.
As opposed to an application service provider which provides application components over a computer network, the services provided by a BSP are more in the area of infrastructure: mail delivery, building security, finance, administration, and human resources.
Unlike an ASP, a BSP provides business processes as services, providing partial or full business process outsourcing. They are often subdivided into two types: "back office" and "front office" BSPs.
