## How to Configure Rates Based on Quantity or Weight in Purchase?

 In this tutorial, we’ll guide you through the **“Rate Per”** option in **Logic ERP**, which allows you to define the unit of measurement for rate calculation in purchase transactions.

***

### Enable “Rate Per” Option in Configuration

* Navigate to the **Purchase Voucher Configuration**.
* Navigate to **Other Settings – 3**.
* Locate the option **“Rate Per”**.
* Select the **desired unit of measurement** (e.g., Unit, KG, Grm etc) from the dropdown list.
* Click **Save** to apply the configuration.

### Apply “Rate Per” in Purchase

* Navigate to the Purchase and create a new Purchase Voucher.
* Select or create the item for which you’ve set the “Rate Per” unit.
* Example:
  * The item **Chana Dal** is supplied in **bags**.
  * The total number of **bags received is 1**.
  * The system **automatically calculates the weight** (in KG) based on predefined conversion factors.

***

### Observe Column Behavior

* The **“Rate Per”** column now displays the unit selected during configuration (e.g., **KG**).
* This value is editable, allowing flexibility to modify the unit directly in the bill if needed.

***

### Rate Calculation Based on Unit

* Key pricing fields such as:
  * **Basic Rate**
  * **Purchase Price**
  * **Sale Price**
  * **MRP** — are calculated based on the selected **unit of measurement**.
* Complete and **save the transaction** after verifying the rate per unit.

***

### Stock Evaluation

* Navigate to the **Stock Report** section.
* Select the item (e.g., Chana Dal) and generate the report.
* **Observation**:
  * The stock is displayed in both **Bags** and **Kilograms**,
  * Allowing for **accurate inventory tracking and reporting**.

### Summary of Benefits

* Define item rates based on **practical units** (e.g., Unit, KG, Grm etc).
* Improve **accuracy** in rate application and **stock visibility**.
* Enable flexible billing by allowing changes directly on the transaction screen.
