Hi Community,
While working on a personal ServiceNow project in my Personal Developer Instance, I spent time deciding when to use Business Rules and when to use Flow Designer. This turned out to be one of the most important design decisions.
Here are a few practical lessons I learned:
• Flow Designer worked best for orchestration, approvals, notifications, and integrations
• Business Rules were useful only when logic truly needed to run close to the database
• Overusing Business Rules made troubleshooting harder and increased technical debt
• Flows were easier to read, explain, and maintain over time
• Mixing both without clear intent created confusion later
This was a self-initiated learning project, but it helped me better understand how to build maintainable and upgrade-safe solutions in ServiceNow.
I’m sharing this in case it helps others making similar decisions.
Question to the community:
How do you decide between Business Rules and Flow Designer in your implementations?
Looking forward to hearing different perspectives.
