## How to Configure Item Merging in Sale Bill?
This tutorial covers how to **merge or manage duplicate item entries** during billing using the *Merge Items* option in Logic ERP’s Sale Voucher Configuration.
***
### Access Configuration
* Navigate to **Sale Voucher Configuration**.
* Select the **relevant billing series**.
* Click to **Other Settings-3**.
* Locate the option labeled "**Merge Items"**.
* From the dropdown, select either:
* Merge Similar Items
* Do Not Merge Similar Items
* Prompt for Duplicate Item
As mentioned above, follow the given steps and select the appropriate option from the dropdown as per your requirement.
***
### Exploring Each Option in Detail
The **Merge Items** dropdown offers multiple parameters that control how duplicate items are handled during billing.
### **Merge Similar Items**
* Purpose: Automatically **"Merge"** quantities of the same item entered multiple times.
* Useful for cleaner bills and consolidated item totals.
**Example:**
If you enter the same item twice:
* **Before**: Two separate lines
* **After**: One line with **combined quantity**
***
### **Do Not Merge Similar Items**
* Purpose: Keeps each item entry **separate**, even if it’s the same product.
* Ideal when item-level notes or batch details need to be retained.
**Example:**
Enter the same item twice:
* Each entry is recorded as a separate line in the bill.
***
### **Prompt for Duplicate Item**
* Purpose: Displays a **confirmation prompt** when a duplicate item is entered.
* Allows billing personnel to decide whether to merge or cancel.
**Example:**
When you try to enter a duplicate item:
* A prompt appears: *“This item already exists in the voucher. Do you want to proceed?”*
***
### Summary of Merge Options
| Option | Behavior |
| -------------------------- | ----------------------------------------- |
| Merge Similar Items | Combines duplicate entries into one line |
| Do Not Merge Similar Items | Keeps all duplicate entries separate |
| Prompt for Duplicate Item | Asks for user confirmation before merging |
***
Using the correct *Merge Items* setting helps streamline billing processes, reduce clutter, and maintain control over inventory representation in invoices.
