# Serving the portion

| Having different portion sizes is very important for restaurants. Options such as **0.5, 1, and 1.5 portions** allow customers to choose according to their **appetite and budget**. This not only **improves customer satisfaction** but also **reduces food waste**. Offering different portion sizes also helps restaurants **serve a wider range of customers**.


## Assigning Portions to Products
To sell products by portion, go to the **Back Office (admin panel)**. From the menu, select the product you want to sell by portion and click **Edit** to modify it. Enable the **Portion** option and click **Save**.
After this feature is activated for the product, it will be possible to **sell the product by portion in the terminal**.
If you want to apply this setting to **multiple products at once**, you can use the **Bulk Operation** feature.

## Applying Portions
To be able to sell a product by portion, the **Portion** function must be enabled.

After this section is activated (if the product allows portion selection), a new window will appear. In this window, you can choose one of the **standard portion options** or enter a **custom portion amount** and proceed with the sale.

If you do not want the **portion selection window** to appear, you can **disable the Portion feature** from the same section.


## Applying a Portion to a Product Later
If a product has been added to the **receipt without selecting a portion**, it can be changed later.
Find the product in the **receipt** and click on it. Then select the desired **portion** from the **Portion** section.

## Portions for Products with Modifiers
Portions can also be enabled for **technical cards (recipes) with modifiers**.
If the **products inside the modifier have the portion feature enabled**, they can be sold by portion. However, if a **product inside the modifier does not have the portion feature enabled**, it will **not be divided into portions**, even if the portion feature is enabled in the main technical card.
In this case, the **portion setting of the product inside the modifier is the determining factor**.
To divide a **technical card with modifiers into portions**, you need to **enable the Portion option in the technical card** and set **“Adapt to Portion” to Yes** in the modifier settings.
