## How to Set Rate per Different Units of Measurement in Sale Bill?

This tutorial explains how to configure and use the **"Rate Per"** option to define item pricing based on a specific **unit of measurement** (e.g., kg, bag, liter) in **Logic ERP**.

***

### Access Sale Voucher Configuration

* Go to **Sale Voucher Configuration**.
* Select the relevant **Billing Series**.
* Navigate to **Other Settings 2**.

* Click **Save** to apply changes.

***

* Ensure the following fields are enabled:
  * **Weight**
  * **Rate Per**
  * **Rate Per In**

> These columns must be visible for correct calculation and display during billing.

***

### **Verify Item Setup**

* Go to the **Item Setup** screen.
* Open the details of the item you intend to transact (e.g., *Chana*).
* Confirm:
  * **Weight per unit** is defined (e.g., 1 bag = 10 kg).
  * **Base unit of measurement** is properly set.

***

### **Process a Sale Transaction**

* Open the **Sale Voucher** window.
* Select the configured **Billing Series**.
* Add the item (e.g., *Chana* sold in bags).
* Since the **Rate Per** is set to **kg**, the rate will be interpreted **per kilogram**, not per bag.

> **Example**:
>
> * 1 bag = 10 kg
> * Rate per kg = ₹400
> * Total = 10 kg × ₹400 = ₹4,000
