# Minimum Commitment App Logic

> The Minimum Commitment App Logic automates the calculation and application of True Up Charges on invoices that do not meet the minimum commitment during Bill Runs.

The Minimum Commitment App Logic automates the calculation and application of True Up Charges on invoices that do not meet the minimum commitment during Bill Runs.

Bill Runs automatically create invoices on a set schedule, and upon completion, a callout to the Minimum Commitment app on Connect is sent. The app will then run against those created invoices and calculate any needed True Up Charges that must be added to the invoices.

For any invoices that need a True Up Charge, because they do not meet the minimum commitment, the app will cancel the invoice, add usage for the appropriate amount and regenerate the invoice. This process will be shown by the created invoice being canceled and in the customer account under **Transactions**. The regenerated invoice with the True Up charge will be displayed. Review of the new (minimum commitment regenerated) invoice, will show one invoice item for the original invoice amount and one invoice item for the True Up Charge.
