## How to Edit Lot Rate While Billing in Sale Bill?

In this tutorial, we’ll guide you through the process of **editing lots during billing**.

***

### Generate a Sales Bill

* Start by generating a **sales bill**.
* In the **Lot Number window**, you can view all the available lots for the selected item.

The lot rate has now been updated successfully.

* Proceed with this lot transaction and **save the bill**.

***

### Verify in Sales Report

* Open the **Sales Report** to review changes.
* Earlier, the same lot had a sale rate of **999**.
* After editing, the sale is now recorded at **1,499.**

### Edit Multiple Lots with Override Option

* Navigate to Inventory and then select **"Overwrite Lot No.\`s/Rates".**
* Select the **item or lot details** to be updated and click **Refresh**.

### Update Rates in Bulk

* Let’s update the sale rate:
  * Currently, the item rate is 100.
  * To apply a new rate to all items, press **F3** on the rate column.
  * Enter the new value, e.g., **299**.

* The updated rate is automatically applied to all items.
* Similarly, let’s override another lot rate:
  * Current rate: **6,000**
  * Updated to **6,500**
  * The lot rate is now revised for all items.

***

### Save and Verify

* Save the changes and proceed to billing.

The updated rates for both lots are now **accurately reflected** during billing.
