In Marg ERP Software, if in the sale bill, the user needs to calculate the Bill Discount after Tax, then it can be done easily.

Suppose the user creates a Sale Bill, in which Qty is '1', Rate is '100' and tax is '12%'.

Bill Discount is '10%'.

• (Rate*Qty) - Bill Discount * Tax Rate.
• (100*1) - 10% * 21%
• 90 * 12% = 10.80
• Gst is calculated after deducting the Bill Discount.

In order to Calculate Bill discount After Tax, the user needs to follow the below steps:

• Go to Master > Marg Setup > Control Room. 

• The user will select the 'Search in All' option.

• The user will search 'Bill Discount' and click on the 'Accept' button.

• In 'Bill Discount AfterTax in Sale/Purc/Both-[B] Type #7%' option, the user will type '#7%'.

• Now, the user will select whether the bill discount needs to be calculated on Sale/Purchase or both.
• Suppose select 'S'.

• Press 'Esc' key.
