How to Prevent Use of Discount Coupons on Discounted Bills?

In this tutorial, we will explore a Logic ERP feature that prevents the use of discount coupons if any other discounts or schemes have already been applied to a bill.


Access Global Settings in Logic Admin

  • Open Logic Admin.

  • Navigate to Global Settings.

  • Under POS Options, go to the POS Options 1 section.

  • Locate and enable the option labeled as:

"Do not allow Discount Coupons in case of discounted bill"

  • Click Save and restart the software to apply the changes.


Implement the Functionality

  • Open the Sale Bill – Touch Screen window.

  • Add an item to the bill.

  • Apply a Trade Discount (e.g., 5%) while entering item details.

  • Now try to apply a discount coupon to the same bill.


System Response

When you attempt to save the voucher:

  • The system will restrict the entry.

  • An error message will appear stating:

    “Discount coupons are not allowed in case of other discounts or schemes.”


Use Case & Benefit

This setting helps:

  • Maintain billing discipline by avoiding overlapping discounts.

  • Ensure that discount rules are enforced consistently.

  • Prevent revenue loss from stacked discount misuse.
