How Commitment Works
When a commitment amount is configured for a subscription:- Commitment Amount: The minimum amount a customer commits to paying per billing period (e.g., $1,000/month). This guarantees minimum revenue for the business.
- Overage Factor: A multiplier applied to usage costs that exceed the commitment amount (e.g., 1.5x). When a customer’s usage surpasses their commitment, the excess usage is charged at this higher rate.
-
Usage Calculation:
- If total usage cost ≤ commitment amount: All usage is charged at standard rates
- If total usage cost > commitment amount: The commitment amount is charged at standard rates, and the excess (overage) is charged at the overage factor rate
Steps to Add Commitments to a Subscription
- Click the Add Subscription button
- Scroll down to the Commitment & Overage section
- Define the commitment amount and overage factor

Understanding True-Up
True-up is a billing mechanism that ensures customers pay their full commitment amount even if their actual usage falls short. When enabled, if a customer’s usage doesn’t meet the minimum commitment amount, they are charged the difference as a “shortfall” or “true-up” fee.How True-Up Works
- During Billing Period: The system tracks all usage and calculates the total usage cost
- At Invoice Generation:
- If usage cost < commitment amount AND true-up is enabled: A true-up line item is added to charge the remaining commitment amount
- If usage cost ≥ commitment amount: No true-up is needed (standard commitment and overage logic applies)
Steps to Add True-Up
You can enable true-up for a subscription during the subscription creation process:- Click the Add Subscription button
- Scroll down to the Commitment & Overage section
- Define the commitment amount and overage factor
- Enable true-up using the toggle switch
