In Marg 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 Masters > Marg Setups > Control Room.

• A 'Control Room' window will appear.

• The user will select ‘Search in all’.
