Abstract: An online software platform (OSP) electronically receives a selection of a workflow framework of a plurality of workflow frameworks. Each workflow framework includes a configuration to embed software-as-a-service (SaaS) functionality provided by the OSP into an application that uses the SaaS functionality. The OSP electronically provides services for determining respective resources for individual relationship instances between different entities. In response to receiving the selection, the OSP causes a remote system that hosts the application to implement the selected workflow framework. This is performed by transmitting a software package to the remote system, in which the software package exposes a set of pre-defined integration points with the SaaS provided by the OSP to provision the steps in one or more of the workflows of the selected workflow framework or defines a specific set of requests and responses with the SaaS provided by the OSP.
