# How to handle Consumables when completing a Service

In the course of giving a service to a Patient, you may need to use some Inventory to complete the service. Such usage of Inventory items is also referred to as **Consumables**. You can setup Clinicea such that it auto deducts inventory item used, whenever a service is given to a Patient.

_For Example: Let us assume you are an Aesthetic Clinic and provides a Service called “Acne Treatment”. When this service is given to the patient, small amounts of AVEDERM Acne Treatment cream and AVEDERM Soothing Face Cleanser is used. These products are not sold to the Patient but it is consumed during the treatment. You will need to manage and account for these products, even though small amounts of them are being consumed._

Let us have a look at how to handle Consumables when completing a Service:

**1.** Go to **Tools** | **Services** | **+Add New.**

**2**. A **Service Item** window will open | **Service Name**, enter the name of the service. For example, _Acne Treatment._ Enter all relevant details (_For more info, please click on [How to add and edit Services](https://help.clinicea.com/en/article/how-to-add-and-edit-services-pfldzq/)_)

**3**. Now scroll down to **Consumables Inventory** | click on **+button** beside **Consumable** **Products**| a **Consumable Products** list will open on the right-hand side of the page.

Click on the **+button** beside the Inventory Item that will be used during the treatment.  
_For example, AVEDERM Acne Treatment cream and AVEDERM Soothing Face Cleanser_

Once added, under **Add New Consumables Inventory** enter the approximate quantity of the products that will be used for the treatment. _For Example, 0.50_ units | **Save**.

**4**. Done! You have successfully added Consumable Inventories to the Service it will be used in. Therefore, when the Patient is billed for the Service, _Acne Treatment, 0.5 of AVEDERM Acne Treatment cream and AVEDERM Soothing Face Cleanser_ will get auto-deducted from Inventory.

**In case you want to charge your Patients for the Consumables used in a Service, Clinicea gives you the option to do so by setting up the following Prerequisite:**

**1**. Go to **Tools** | **Organisation** | **Preferences** | **Financial.**

**2**. Switch on **Auto add Consumable used in a Service to a Bill.**

**3**. This preference will auto-add Consumables of a Service to the Invoice as a billable item when that Service is billed. _Example: Service Acne Treatment is added as a Bill Item and the linked consumables AVEDERM Acne Treatment cream and AVEDERM Soothing Face Cleanser get auto-added to the Bill._
