Flow vs Apex: A Practical Decision Criteria

Flow and Apex are not enemies. The real question is maintainability: who owns the process, how complex the logic is, and how much testing or reuse the behavior needs.

• Use Flow for transparent business automation that admins can own.
• Use Apex for complex branching, reusable services, integrations and heavy data processing.
• Use both when Flow orchestrates and Apex encapsulates a complex operation.
