Total amount and tax amount wrong, how could this be?
« on: October 10, 2013, 16:34:18 pm »
Hello,
We have a website selling martial arts stuff. We have a problem on the total amount of the orders. Here is an example of an purchase order (the Coupon Discount = 15% on all products. Tax rate is 19.6% on all products) :


QtyProductPriceTotal
50xxx€12.00€600.00
1yyy€95.68€95.68
SubTotal€695.68
Coupon Discount-€104.35
Shipping and Handling Fee€5.98
Tax Total€97.89
Total€580.21


The Coupon Discount is right : 15% form €695.68 = €104.352
Total amount left to pay after Coupon Discount : €695.68 - €104.352 = €591.328
Shipping and Handling Fee is €5.98

So total should be €591.328 + €5.98 = €597.308 but... the purchase order indicates €580.21 !!!
The tax rate in our country is 19.6% of the total so it should be €597.308 * 19.6% = €117.07 but... the purchase order indicates €97.89 !!!

Does anybody have any idea what could be wrong here? Is it the use of a Coupon Discount that makes this mess? Am i doing something wrong somewhere?

Thanks for any help!
