Cost Management

Understand workflow costs and learn strategies to optimize spending while maintaining performance.

Understanding Workflow Costs

Workflows consume AI credits based on what they do. The main cost drivers are:

AI Agent Nodes

The biggest expense in most workflows. Costs depend on:

• Model used: Larger models cost more than smaller ones
• Input length: How much data you send to the agent
• Output length: How much the agent generates
• Tool usage: Web searches, code execution, and integrations add costs

Other Nodes

• Web Search nodes: Small fee per search
• Action nodes: Usually free (no AI involved)
• Code/Condition/Loop nodes: Free (just logic)
• HTTP requests and notifications: Free

Monitoring Costs

Per-Node Costs

After a workflow run, each node shows a cost badge in its footer. Hover over it to see:

• Total cost for that node
• Per-model breakdown with input/output tokens
• Cost per model used

Per-Run Costs

View run costs in the Runs tab:

1. Click on any run in the history
2. See total execution cost
3. Click individual nodes to see their cost breakdown

Workflow-Level Costs

The history panel shows aggregate stats:

• Total runs
• Nodes executed
• Total cost (all-time)
• Average cost per run

Setting Cost Limits

Protect yourself from unexpected charges in the workflow Settings panel:

Monthly Limit

Set a maximum spending cap for the workflow per month:

1. Go to workflow settings
2. Set Monthly Limit (e.g., $100)
3. Workflow pauses when limit is reached
4. Progress bar shows current spend vs limit

Per-Execution Limit

Prevent runaway costs from a single run:

1. Set Execution Limit (e.g., $5 per run)
2. Run stops if it exceeds this amount
3. Useful for catching issues with loops or large data

Hourly Rate Limit

Control how often the workflow can run:

1. Set Max Executions Per Hour
2. Prevents trigger floods from overwhelming your budget
3. Useful for webhook-triggered workflows

Alert Thresholds

Get notified before hitting limits:

1. Add custom alert amounts (e.g., $25,$50)
2. Receive email notifications when crossing each threshold
3. Built-in alerts at 50% and 90% of monthly limit

When a workflow hits its spending limit, it pauses automatically. Increase the limit or wait until the next billing period to resume.

Cost Limits Hierarchy

Cost limits are enforced at multiple levels. Higher-level limits take precedence:

Workspace-Level Limits (Admin)

Admins can set workspace-wide limits in Settings → Products → Workflows:

Setting	Description
Workspace Spend Cap	Maximum total spend across all workflows (default: €500/month)
Max Monthly Limit Per Workflow	Caps what users can set as their workflow’s monthly limit
Monthly Run Limit	Maximum workflow executions per month (based on plan)

When a workspace-level limit is reached, all workflows pause regardless of their individual settings.

Workflow-Level Limits (User)

Users can set limits per workflow (within admin constraints):

Setting	Description
Monthly Limit	Capped by admin’s “Max Monthly Limit Per Workflow” setting
Per-Execution Limit	Stops a single run if it exceeds this amount
Hourly Rate Limit	Maximum executions per hour

The workflow monthly limit cannot exceed the admin-configured maximum. If an admin sets the max at $50, users cannot set their workflow limit higher than$50.

Optimization Strategies

Choose the Right Model

Don’t use premium models for simple tasks:

Task	Model Choice
Extract email from text	Smaller/faster model ✅
Complex reasoning	Larger model ✅
Date formatting	Code node (free) ✅

Optimize Agent Prompts

Shorter, clearer prompts cost less and work better:

Analyze this feedback. Return:
- Sentiment: positive/neutral/negative
- Urgency: low/medium/high
- Key issue (1 sentence)

Feedback: {{trigger.output.message}}

Use structured outputs. They’re more reliable and prevent the model from generating unnecessary explanatory text.

Use Code for Simple Transformations

Don’t use AI for tasks that code can handle:

Free with Code Node:

const date = new Date(trigger.output.date);
return {
  formatted: date.toISOString().split('T')[0]  // YYYY-MM-DD
};

When to use code instead of AI:

• Date/time formatting
• Mathematical calculations
• Data filtering and sorting
• String manipulation
• JSON parsing/formatting

Cost-Effective Patterns

Smart Filtering

Filter data before sending to AI:

Trigger (100 items) → Code: Filter relevant items (20 items)
                    → Agent: Process 20 items (not 100)

Progressive Enhancement

Start cheap, escalate only if needed:

Data → Quick check (code) → [SIMPLE] → Done
                          → [COMPLEX] → AI analysis

Estimating Costs Before Launch

1. Count Expected Runs

• Forms: Expected submissions per month
• Scheduled: Runs per day × 30
• Webhooks: Events per month from integration

2. Test with Real Data

Run 5-10 tests and check the cost badges:

Average cost per run: $0.13
Expected monthly runs: 1,000
Estimated monthly cost: $130
Add 20% buffer: $156

3. Set Appropriate Limits

Monthly limit: $200 (includes buffer)
Per-run limit: $1.00 (catches anomalies)
Hourly rate: Based on expected trigger frequency
