Can i use flow designer instead of business rules

[samadam]

Is using a flow designer a good idea to use instead of using business rules? Are there any restrictions or implications?

Flows cannot run in the before sequence. So if yo need to create a before business rule, that is not possible. Flows can only run in the after sequence or asynchronously.

Thank you, Are there any performance implications on using flows?

I am sure Flows are heavier on the system than business rules, though ServiceNow says otherwise. I don't see how that could be, given that by adding a Flow one "imports" the Flow engine and any overhead that that entails. Plus it has limitations with regards to how many steps the Flow can contain before it becomes bad performing. The OOB box limit is 50 and while it can be increased, it is not recommended.
