## How to Apply Party -wise Billing locks, Credit limits and Bill limits?
In this tutorial, we will learn how to **configure and apply party-wise billing locks in Logic ERP**. Party-wise billing locks help organizations control billing behavior by restricting transactions based on customer rules such as outstanding dues, rate protection, discount control, bill limits, and credit limits.
***
### **Access the Party-Wise Billing Locks Setup**
* Navigate to **Main Menu**
* Open the **Setup Module**
* Go to the **Party Wise Settings** section
* Click on **Party-Wise Billing Locks**
This window allows you to define multiple billing restrictions for selected customers.
***
### **Define the Lock Scope**
* Select the **Lock Type**
* Define whether the lock should apply:
* **Series-wise**, or
* **Agent-wise**
* Under **Batch Mode Only**:
* Select the required **Customer**
* Choose the **Series** on which the billing locks should apply
***
### **Apply “Stop Billing” Lock**
* Enable the **Stop Billing** option
* Save the changes
#### **Result**
* When you open the **Sales Bill** window and select this customer:
* The system immediately displays an error message
* Billing is completely blocked before item entry
* You cannot proceed further with the transaction
This lock is useful when billing needs to be completely halted for a customer.
***
### **Apply Field-Level Locks (CD, TD, Rate)**
* Enable locks for:
* **CD (Cash Discount)**
* **TD (Trade Discount)**
* **Rate**
#### **Result**
* These fields become **non-editable during billing**
* Users cannot manually override or modify the values at runtime
**Example**
* Apply the **Rate Lock**
* Open a Sale Bill and enter items
* The **Rate field remains locked**, preventing any manual changes
***
### **Apply “Allow Billing Only If No Dues” Lock**
* Enable **Allow Billing Only If No Dues**
* Save the changes
#### **How It Works**
* Create and save a **Credit Sale Bill** for the customer
* The bill amount becomes outstanding
* When you try to initiate a **new transaction** for the same customer:
* The system displays a warning message
* Billing is blocked due to **pending dues**
Billing will only be allowed once all outstanding amounts are cleared.
***
### **Apply Bill Limit and Credit Limit Locks**
These limits help control customer exposure.
#### **Bill Limit**
* Restricts billing if a **single bill amount exceeds the defined limit**
#### **Credit Limit**
* Restricts billing if **total outstanding exceeds the allowed credit limit**
**Example**
* Bill Limit defined: **₹12,000**
* Create a sale bill exceeding this amount
* On saving, the system displays an error:
> *“*Bill Limit for Party + Series is Set to 12000.00... Cannot Proceed*.”*
The bill will not be saved until the amount falls within the allowed limit.
***
### **Conclusion**
Party-wise billing locks in Logic ERP provide powerful control over sales transactions by:
* Preventing unauthorized billing
* Enforcing rate and discount discipline
* Managing credit exposure
* Ensuring billing compliance based on dues and limits
By configuring these locks effectively, businesses can **reduce financial risk, enforce policies, and maintain strong credit control** across customers.
