Gartner defines business process as a service (BPaaS) as the delivery of business process outsourcing (BPO) services that are sourced from the cloud and constructed for multitenancy. Services are often automated, and where human process actors are required, there is no overtly dedicated labor pool per client. The pricing models are consumption-based or subscription-based commercial terms. As a cloud service, the BPaaS model is accessed via Internet-based technologies.
