In this paper we describe PBroker, a web-based external service which supports the procurement and administration of freelancer services. Based on a description of the freelancer market, the functionalities of the PBroker platform are described. We discuss the business model of and present experiences with the system. One of the tasks supported by the PBroker system is the management of freelancer contracts. This contract management module has recently been enlarged to a system called „ConTracker“ which supports the management of all types of contracts by structured documentation of contractual issues and alert mechanisms for time-dependent events.B2B platformcase studiescontract managementfreelancerhuman resource managementinnovative productsintermediariesoutsourcingText/Journal Article1861-8936
