## How to Configure a Quantity based Discount % Scheme in Sale Bill?
In this Tutorial, we will learn how to configure a **Quantity Basis Cash Discount Scheme** in Logic ERP. Let’s get started.
***
### **Access to Scheme Campaign**
* Navigate to the **Configuration** menu and open the **Setup Scheme Campaign** window.
* Click **Refresh**.
* Enter the **Scheme Campaign Name** and define the **active date range** for the scheme.
* Save the scheme.
***
### **Configure Group Options**
* Open the **Group Options** tab.
* Select the **Scheme Campaign** you created.
* Enter the **Group Name**.
* In the **Scheme Group Type** column, press the **Space key** and choose the option on which the scheme will be applied (e.g., Company, Brand, Item Group, etc.).
* Save the changes.
***
### **Assign to Brand or Company**
* Go to the **Scheme Group** tab.
* Select the **Company or Brand** on which this scheme should be applicable.
* Click **Save**.
***
### **Define Slab Details**
* Open the **Scheme Campaign Slab Details** window.
* Select the relevant **Scheme Campaign**.
* Since this is a **Quantity-Based Slab Scheme**, enter **1** in the *Minimum Quantity/Value* field.
* Set the **Scheme Basis** to **Quantity**.
* Define the slab structure as follows:
* When **1 quantity** is transacted → **5% Cash Discount (CD)**
* When **2 quantities** are transacted → **10% CD**
* When **3 quantities** are transacted → **30% CD**
* After entering all slab details, **save** the configuration.
***
### **Implement in Scheme in Sale Bill**
* Open the **Sale Bill Touch Screen** window and create a new transaction.
* Select an item belonging to the brand on which the scheme is defined.
**Case 1: Quantity = 1**
* Enter quantity **1** and save the bill.
* The **Available Schemes** window will appear.
* Tick to apply the scheme, and a **5% CD** will be applied.
**Case 2: Quantity = 2**
* Increase the quantity to **2** (either by adding another item or updating the same item).
* Save the bill.
* Tick to apply the scheme, and a **10% CD** will be applied.
**Case 3: Quantity = 3**
* Increase the quantity to **3**.
* Save the bill and apply the scheme.
* A **30% CD** will be applied as per the configured slab.
***
### **Conclusion**
A quantity-based cash discount scheme helps automate discounts based on item quantities. Once configured, the system automatically applies the correct discount slab—5%, 10%, or 30%—depending on the total quantity selected in the bill. This ensures accurate and efficient billing without manual intervention.
