## How to Apply Net Rate and Free Units Scheme as Value in Sale Bill?

In this tutorial, we’ll learn how to **apply schemes manually at runtime** while billing in Logic ERP.

***

### Configure the Net Rate Position

* Go to **Sale Voucher Configuration** and select the relevant **Billing Series**.
* Open **Calculation Mode**.
* **Count the fields** step by step until you reach the field you want to include in the net rate.
  * In our example, we count up to **Tax-3**, which means all fields up to Tax-3 will be considered while calculating the net rate.

* Next, go to **Print Options**.
* Define the **Net Rate Position** by adding **1** to the counted field.
  * For example, if you counted up to 8, the net rate position will be 9.
* Select **All Net Rates** for the net rate application.

### Apply Schemes at Runtime – Method 1 (Net Rate Adjustment)

* Open the **Billing Screen** and start a new transaction.
* In the **Sale Rate** column, press **F7** to open the **Net Rate Window**.
* Enter the desired **Net Rate** at which you want to sell the item.
  * For example, if you enter **₹70**, the software automatically adjusts the sale rate to **₹66.67** because it calculates the tax component included in the entered net rate.

**Tip:**\
You only need to enter the net rate; the system takes care of the rest.\
You can also adjust the **Net Rate Position** for individual sale bills if required.

### Apply Schemes at Runtime – Method 2 (Free Units)

* Transact an item on the billing screen.
* Press **F7** on the **Sale Rate** field.
* Enter the quantity including the free units.
  * For example: **10 + 1** or **15 + 1**.

* Observe how the **Scheme per Unit** and **Rate** fields change:
  * As you increase the number of free units, the **rate decreases** while the **scheme per unit increases**.

* Conversely, reducing the free units increases the rate.
* The value of the free units is displayed under the **Scheme per Unit** field.

### Final Outcome

* You can now easily apply manual schemes in two ways:
  * By **entering the net rate directly**.
  * Or by **adding free units to adjust the effective rate**.
* The system automatically handles all underlying tax calculations and scheme adjustments.
