Overview
Salesforce offers three native automation tools: Workflow Rules, Process Builder, and Flow. Most orgs use all three inconsistently, creating a tangled mess of automations that nobody fully understands. When something breaks—and it will—you're left hunting through decades of accumulated logic to find the culprit.
This guide breaks down each tool's strengths, limitations, and ideal use cases. More importantly, it explains why Flow should be your default choice going forward, and how to strategically migrate away from the legacy tools that Salesforce is phasing out.
If you're a GTM Engineer responsible for Salesforce field mapping and automation, understanding these distinctions isn't optional—it's essential for building systems that scale without creating technical debt.
Quick Comparison: All Three Tools at a Glance
| Feature | Workflow Rules | Process Builder | Flow |
|---|---|---|---|
| Status | Retired (no new creation) | Retiring (migrate to Flow) | Active (recommended) |
| Trigger Types | Record create/edit only | Record changes, platform events | All triggers + scheduled + screen |
| Actions Available | 4 basic actions | 10+ actions | Unlimited with Apex integration |
| Complexity Handling | Simple only | Moderate | Enterprise-grade |
| Debugging | Minimal | Limited | Full debug logs + Flow Debugger |
| Loops & Collections | No | No | Yes |
| Error Handling | None | Basic | Fault paths + custom error handling |
| Before-Save Updates | No | No | Yes (no DML consumption) |
As of Winter '23, Salesforce stopped allowing new Workflow Rule creation. Process Builder entered maintenance mode in Spring '24. Both tools will eventually be sunset entirely. Flow is the only automation tool receiving active development and new features.
Workflow Rules: The Legacy Foundation
Workflow Rules were Salesforce's original point-and-click automation tool, introduced over 15 years ago. They handle simple, single-object automations triggered by record creation or updates.
What Workflow Rules Can Do
Workflow Rules support exactly four actions:
- Field Updates: Modify field values on the triggering record or related parent records
- Email Alerts: Send template-based emails to specified recipients
- Tasks: Create task records assigned to users or roles
- Outbound Messages: Send SOAP messages to external endpoints
When Workflow Rules Made Sense
In their era, Workflow Rules were perfect for straightforward scenarios like auto-populating a region field based on state, sending a notification when a high-value opportunity closes, or creating follow-up tasks on lead conversion.
Why They're Being Retired
Workflow Rules can't handle multi-object updates, complex conditional logic, loops, or error handling. They also create order-of-execution headaches when multiple rules fire on the same object. Most critically, they're invisible to modern CRM hygiene strategies and nearly impossible to document systematically.
If you have existing Workflow Rules that work reliably and aren't causing issues, don't rush to migrate them. Focus migration efforts on rules that interact with other automations or need enhanced functionality. Salesforce provides a Migrate to Flow tool that handles straightforward conversions automatically.
Process Builder: The Middle Child
Process Builder arrived in 2015 as Salesforce's answer to Workflow Rules' limitations. It introduced a visual interface with more actions and the ability to evaluate multiple criteria in sequence.
Process Builder Capabilities
Beyond Workflow Rules' four actions, Process Builder added:
- Create, update, or delete any related record
- Launch Flows (calling Flow from Process Builder)
- Post to Chatter
- Submit records for approval
- Call Apex code
- Invoke Quick Actions
- Trigger platform events
The Process Builder Problem
Despite its expanded capabilities, Process Builder introduced serious performance and maintenance issues that became apparent at scale:
Performance Bottlenecks: Process Builder executes record-by-record, not in bulk. When you update 200 records, it runs 200 separate times. This quickly hits governor limits and causes timeout failures in batch operations.
Multiple Processes Per Object: Unlike Flow, you can have multiple active Process Builders on the same object. When they all fire, order of execution becomes unpredictable, and debugging becomes a nightmare.
No Error Handling: When a Process Builder fails, the entire transaction rolls back with minimal debugging information. There's no way to catch errors and handle them gracefully.
For teams managing complex data flows between CRM and other tools, Process Builder's limitations become deal-breakers quickly.
The Hidden Cost of Process Builder Sprawl
Many orgs accumulated dozens of Process Builders over the years, often with overlapping criteria and conflicting actions. This sprawl directly impacts CRM data quality and makes it nearly impossible to predict what happens when a record changes.
Flow: The Modern Standard
Flow (specifically Flow Builder, formerly Visual Flow) is Salesforce's current and future automation platform. It combines the simplicity of point-and-click tools with the power previously reserved for custom Apex development.
Flow Types You Need to Know
| Flow Type | Trigger | Common Use Cases |
|---|---|---|
| Record-Triggered Flow | Record create, update, delete | Field updates, related record creation, validation |
| Schedule-Triggered Flow | Time-based (hourly, daily, weekly) | Batch updates, data refresh operations, cleanup jobs |
| Screen Flow | User interaction | Guided data entry, wizards, custom actions |
| Autolaunched Flow | Called by other automations | Reusable logic modules, subflows |
| Platform Event-Triggered | Platform event messages | Integration patterns, async processing |
Why Flow Should Be Your Default
Before-Save Updates: Record-Triggered Flows can run before the record saves, modifying field values without consuming DML operations. This is a massive performance improvement over Workflow Rules and Process Builder.
Bulk Processing: Flow handles collections natively. You can loop through related records, perform bulk updates, and process large datasets efficiently within governor limits.
Error Handling: Fault paths let you catch errors and handle them gracefully—logging issues, sending alerts, or taking corrective action instead of failing the entire transaction.
Debugging: Flow Debugger shows exactly what happened at each step, with variable values and decision outcomes. Combined with Debug Logs, you get complete visibility into automation execution.
Subflows: Build reusable automation components that can be called from multiple parent Flows. This promotes DRY principles and makes maintenance manageable.
Use one Record-Triggered Flow per object with entry conditions to handle different scenarios. This gives you complete control over order of execution and makes the automation logic discoverable by future administrators.
Decision Framework: Choosing the Right Approach
Given Salesforce's direction, the decision framework is straightforward:
Always Start with Flow
For any new automation requirement, Flow should be your first choice. It handles everything from simple field updates to complex multi-object orchestrations.
Assess Existing Automations
Audit your org's Workflow Rules and Process Builders. Prioritize migration for automations that cause performance issues, interact with external systems like Clay data syncs, or need enhanced functionality.
Use Salesforce's Migration Tools
The Migrate to Flow tool handles straightforward conversions automatically. For complex Process Builders with multiple criteria groups, manual recreation in Flow often produces cleaner results.
Consider Apex for Edge Cases
Some scenarios—like complex calculations, external API callouts with retry logic, or extreme bulk processing—still benefit from custom Apex. Flow can call Apex Invocable Actions to combine declarative simplicity with code-level power.
Common Scenarios and Recommended Approaches
| Scenario | Recommended Tool | Reasoning |
|---|---|---|
| Auto-populate fields on save | Before-Save Record-Triggered Flow | No DML consumption, immediate execution |
| Create related records | After-Save Record-Triggered Flow | Full control over creation logic and error handling |
| Send notification emails | Record-Triggered Flow with Email Action | Can include complex conditional logic |
| Sync data to external systems | Platform Event + Flow or Apex | Async processing prevents timeout issues |
| Nightly data cleanup | Schedule-Triggered Flow | Process records in batches, full debugging |
| Guided user data entry | Screen Flow | Dynamic forms with validation and branching |
Building a Migration Strategy
Migrating from legacy automation tools requires a systematic approach. Rushing migrations without proper planning leads to broken integrations and data issues—exactly what teams focused on CRM enrichment and data quality work hard to avoid.
Phase 1: Discovery and Documentation
Start by creating a complete inventory of existing automations. Salesforce Setup provides views for Workflow Rules and Process Builders, but you'll need to document:
- What each automation does (business logic)
- When it fires (trigger conditions)
- What it affects (objects and fields modified)
- Dependencies (other automations or integrations that rely on it)
Phase 2: Consolidation Planning
Before migrating individual automations, look for consolidation opportunities. Multiple Workflow Rules updating the same object can often become a single Flow with branching logic. This reduces complexity and improves performance.
Phase 3: Phased Migration
Migrate in waves based on risk and complexity:
- Wave 1: Simple, standalone automations with no dependencies
- Wave 2: Automations that interact with each other on the same object
- Wave 3: Automations that trigger external integrations or cross-object updates
Phase 4: Testing and Validation
Each migration requires testing in a sandbox environment that mirrors production data volumes. Bulk operations especially need validation—an automation that works for single records might fail when processing thousands.
If your Salesforce automations feed data to external platforms for prospect research automation or lead scoring, ensure your migration maintains the same data formats and timing. Tools like Octave can help validate that downstream systems continue receiving expected data structures after Flow migration.
Flow Development Best Practices
Once you've committed to Flow as your standard, follow these patterns to build maintainable automations:
Naming Conventions
Adopt a consistent naming scheme: [Object]_[Trigger]_[Purpose]. For example: Opportunity_AfterSave_UpdateAccountRollups. This makes Flows discoverable and self-documenting.
One Flow Per Object Per Trigger Type
Consolidate all before-save logic for an object into one Flow, and all after-save logic into another. Use entry conditions to handle different scenarios within the Flow. This eliminates order-of-execution ambiguity.
Use Subflows for Reusable Logic
When the same logic appears in multiple Flows, extract it into an Autolaunched Flow that can be called as a subflow. Update once, propagate everywhere.
Implement Proper Error Handling
Every Flow that creates or updates records should have fault paths. At minimum, log errors to a custom object for review. For critical processes, trigger alerts to administrators.
Document with Description Fields
Flow Builder allows descriptions on Flows and individual elements. Use them. Future you (or your replacement) will thank you.
Connecting Flow to Your GTM Stack
Salesforce automation rarely exists in isolation. Modern GTM teams connect Salesforce to enrichment tools, sequencers, and AI-powered outbound systems. Flow provides multiple integration patterns:
Platform Events for Async Communication
Instead of making synchronous callouts from Flow (which risk timeouts and governor limits), publish platform events that external systems can subscribe to. This decouples Salesforce automation from integration timing.
External Services for REST APIs
Flow's External Services feature generates Apex classes from OpenAPI specifications, letting you call external APIs directly from Flow without custom code.
Outbound Messages for Legacy Integrations
Some older integrations still expect Workflow Rule-style outbound messages. Flow can trigger these via Workflow Actions for backward compatibility during migration periods.
For teams building sophisticated GTM orchestrations, tools like Octave provide a context layer that complements Salesforce automation. While Flow handles the CRM-side logic, a context engine ensures that enrichment data, scoring outputs, and field mappings stay synchronized across your entire stack.
Common Pitfalls to Avoid
Recursive Triggers
A Flow that updates a record can trigger another Flow on that same object, which updates again, which triggers again. Use static variables or custom settings to track execution context and prevent infinite loops.
Governor Limit Violations
Even with Flow's bulk handling, you can still hit limits. Queries inside loops, excessive record creation, and too many DML operations will fail. Always test with realistic data volumes.
Mixing Automation Tools
Having Workflow Rules, Process Builders, and Flows all active on the same object creates unpredictable behavior. The order of execution isn't obvious, and debugging becomes extremely difficult.
Ignoring Error Paths
The default behavior when a Flow fails is to roll back the entire transaction. For user-facing Screen Flows, this creates a terrible experience. For backend automations, it can leave data in inconsistent states.
Frequently Asked Questions
Yes, existing Workflow Rules continue to function. However, you can no longer create new ones, and Salesforce strongly encourages migration to Flow. Plan to migrate before Salesforce eventually sunsets the feature entirely.
Process Builder is in maintenance mode. You can still create and edit Process Builders, but no new features are being added. Salesforce recommends migrating to Flow for all new automations and gradually converting existing Process Builders.
Salesforce provides a Migrate to Flow tool that handles straightforward conversions. For complex Process Builders with multiple criteria groups or scheduled actions, manual recreation in Flow often produces cleaner, more maintainable results.
Consider Apex when you need complex calculations that Flow can't handle efficiently, external API callouts with sophisticated retry logic, processing volumes that push Flow to its limits, or tight integration with other Apex code. Even then, Flow can call Apex Invocable Actions to combine both approaches.
Flow's platform event and external service capabilities actually improve integration options. However, during migration, test thoroughly to ensure timing and data formats remain consistent for downstream systems like enrichment platforms and lead qualification tools.
Moving Forward with Flow
The automation landscape in Salesforce has consolidated. Flow is no longer one option among many—it's the platform's strategic direction. GTM Engineers who master Flow position themselves to build scalable, maintainable automation that supports sophisticated revenue operations.
Start by auditing your current automation inventory. Identify quick wins for migration, consolidate overlapping logic, and establish Flow development standards for your team. The investment pays dividends in reduced debugging time, improved performance, and systems that can evolve with your GTM strategy.
For teams orchestrating complex GTM workflows across Salesforce and external tools, consider how a context engine like Octave complements your CRM automation. While Flow handles Salesforce-side logic, maintaining consistent context across your enrichment, scoring, and engagement tools requires purpose-built infrastructure.
