## How to Configure a Separate Customer for Account Posting in Sales Bills?
In this tutorial, we will learn how to **link a Billing Account with an Entry Account for Sales Documents in Logic ERP**.\
This feature allows businesses to **generate sales bills under one customer while posting the accounting entry to another linked account automatically**.
***
### Open Customer Linking Setup
* Navigate to the **Main Menu**
* Open the **Setup Module**
* Expand **Set Other Account Details**
* Click **Customer Linking for Sale Documents A/c Entry**
* This will open the **Customer Linking configuration window**.

### Select Entry Account and Billing Account
Now define the accounts that will be linked together.
**Entry Account**
* Select the **Entry Account** where the accounting entry will be posted.
**Billing Account**
* Select the **Billing Account** that will be used while generating the sales bill.
**Example in this demonstration:**
* **Billing Account:** Logic ERP - Punjab
* **Entry Account:** Logic ERP - Delhi
> This means that whenever a **Sales Bill is created for ABC Mart Jaipur**, the **accounting entry will automatically be posted to ABC Mart Delhi**.
* Click **Save** to store the linking configuration.

### Enable Entry Account Display in Billing Window (Optional)
If you want to **view the entry posting account directly in the billing window**, enable the required column.
**Steps**

* Navigate to **Column Lock Options**
* Enable **Account Entry Customer Column**
* Click **Save** to apply the configuration.
**Refresh the Billing Window**

### Generate a Sales Bill Using the Linked Account
* Now create a sales transaction to observe how the linking works.
* In the **Billing Account field**
* Select: **Logic ERP - Punjab**
* As soon as the billing account is selected
* The **linked Entry Account (Logic ERP - Delhi)** will **automatically appear** in the **Account Entry Customer column**.
If required, this entry account can **also be changed manually**.
**Now:**
* Add the **item details**

* Click **Save**
The **Sales Bill will be generated successfully**.

* **Entry Account:** Logic ERP - Delhi
* Generate the report.
***
### Understanding the Ledger Result
