The business events feature is based on the event-driven architecture pattern and has the following benefits:

• Business events are produced in near real time, which means they enable faster notifications and integration scenarios.
• Consumers of business events are decoupled from Finance and Operations.
• No point-to point-integrations. It's easy to add new consumers to the system.
• Highly scalable and distributed.

At a high level, business events are most suitable for business events notifications, third-party integration, and automating business processes through the workflow. The Microsoft product team is doing a tremendous job in documenting various potential use cases for business events in detail.
