Salesforce Flow is one of the most powerful automation tools on the platform — but also one of the easiest to misuse. These 12 best practices will save you from governor limits, debugging nightmares, and un-maintainable flows.
1. Bulkify Your Flows
Always design flows to process records in bulk. Avoid DML operations inside loops — use collection variables and perform DML after the loop exits.
2. Use Decision Elements Over Multiple Flows
One well-structured flow with Decision elements is easier to maintain than three separate flows on the same trigger. Consolidate where possible.
3. Name Everything Meaningfully
Use descriptive API names and labels. "Flow_2" means nothing in six months. "Account_AfterSave_SyncOpportunityStage" tells the whole story.
4. Handle Null Values Explicitly
Always check for null before using a variable. A null check decision prevents cryptic runtime errors from reaching your users.
5. Store Complex Logic in Apex
Complex conditional logic, large data operations, or anything requiring transaction control belongs in Apex — not a nested flow with 40 branches.
6. Use Scheduled Paths for Per-Record Timing
Scheduled Paths in Record-Triggered Flows outperform standalone Scheduled Flows for most per-record timing requirements.
7. Always Test with Bulk Records
Run your flow test with 200 records simultaneously. If it's bulk-safe, it will pass without hitting governor limits.
8. Deactivate, Don't Delete Old Flows
Keep old flow versions inactive rather than deleting — you may need the history for debugging or rollback reference.
9. Avoid SOQL Lookups Inside Loops
SOQL inside a loop burns your query limit. Query before the loop, store results in a collection, then reference the collection inside.
10. Document With Description Fields
Use the Description field on every flow and its elements. Future admins will be grateful — and so will you in six months.
11. Use Fault Paths
Add a Fault Path to every DML or Apex action element. At minimum, create a task or send an email when something fails.
12. Version Control Your Flows
Export your flow metadata to a git repository. Salesforce doesn't have built-in version history useful enough for complex flow changes.
