# What is a needs product and how to use it

**What is a needs product and how to use it**

If you need to **charge an amount for each diaper change**, you can use the **needs product** to automatically calculate the costs to apply to family members based on the records made by educators in the logbook.

**How to create a needs product**

1. **Access product management**

• Go to **Administration → Products**.

• Click on the **”+ New”** button at the top right.

2. **Fill in the product fields**

• **Product type**: Select **“Needs”**.

• **Internal product name**: Enter a name useful for identifying the product (e.g. *Diaper change €2*). This name is visible only internally.

• **Short name**: Enter the name that the parent will see on the invoice (e.g. *Diaper change*).

• **Description** *(optional)*: You can enter additional details or use **student variables**, selectable by clicking on the available light blue buttons.

• **Amount**: Indicate the cost for **single change** or **single diaper**.

• **VAT rate**: Select the VAT rate to apply and specify whether the amount is **VAT included** or **VAT excluded**.

3. **Set the reference period**

• You can choose whether to **display or not the reference period**.

• By selecting **“Previous”**, the system will automatically insert the **start and end date of the previous month** relative to the document date.

4. **Define the types of changes to charge**

• You can choose to charge the cost for a logbook record related to:

• **Pee**

• **Poop**

• **Both types**

5. **Save the product**

• After completing the setup, click the **“Save”** button at the top right.

• You will be redirected to the **Product List** page, where you can:

• **Edit** the product by clicking **on the pencil icon**.

• **Duplicate** it by clicking **on the gray “Duplicate” icon** to create a variant with different prices.

• **Delete** it by clicking **on the red “Delete” icon**.

**How to use the needs product**

The **needs product** can be used in two ways:

1. **Manual**: Entering it manually during invoice creation.

2. **Automatic**: Including it in a **package** to automatically generate the charge based on the data recorded in the logbook.

We recommend consulting the guides related to **packages** for more efficient management of automatic invoicing.
