# Invoice Auto Consumption

The **Invoice Auto Consumption** feature simplifies tracking and managing items (services, drugs, consumables, etc...) by automating quantity updates. This feature minimizes repetitive billing tasks, enhances accuracy, and optimizes ongoing item management for subsequent patient visits, improving efficiency for healthcare facilities and patients.

***

### Steps to Enable Auto Consumption

*  Use the standard [**Invoice Creation Steps**](/uniteemr/application-modules/billing/invoice/create-invoice.md) to invoice the item. While creating the invoice: 
  * Enable the **Invoice Auto Consumption** checkbox in the **Patient Invoice(s)** section.
  * Enter the quantity for auto consumption in the **Quantity (Qty)** field in the **Invoice Details** section.

* After creating the Auto Consumption invoice, the front desk staff must create an [**Auto Consumption Appointment**](/uniteemr/application-modules/scheduler/appointment-booking/auto-consumption.md). Once the appointment transitions to the patient queue, the item will be automatically consumed.
