I had been looking at using BPMN and an implementation of Camunda as a reasonable goal, but I never found an implementation of running a BPMN service that I liked in the time I had allotted.

It also has timers to generate events so you can have that monthly event start and trigger some other actions, and it also includes failure paths.
