Hi,

I am wondering on how the system is calculating the values in Sales Invoice. Here is the invoice data:

Item Qty: 6

Item Rate: 362.75

Net Amount: 2,176.5

There is as:

Type: On Net Total

Rate: 10%

Is Tax Included in the Base Rate: Yes (ticked)

There is Additional Discount as:

10% On Net Total

I would like to show all the details in the invoice printout as below:

**Items Table**

Item, Qty, Rate, Amount

**Summary**

(a) Total Amount Excluding Tax: xxx (Sum of amounts in Items Table)

(b) GST 10%: xxx

© Subtotal: xxx (a+b)

(d) Discount 10%: xxx

(e) Net Amount: (c-d)

Currently, there is no print format to show properly and I couldn’t figure out how the discounts are calculated in this scenario. I have the following figures showing in the system:

Total: 2,176.5

Net Total: 1,780.772

GST: 178.077

Discount: 197.864

I couldn’t figure out how the system is calculating the discounts and GST as 10% doesn’t make up the values. I have attached the screenshots of the same.
