Tax Calculation after discount

Seyi,

Thanks for your AWO Coupon, which works great! But I have a client who wants things to look differently in the cart view. It is for a winery and they wanted to have a 10% automatic discount taken when a customer orders a case (12 bottles or more), so I have that set up and working. Originally, I had the tax calculating after discount, which is what they wanted, but they want the the 10% discount to display exactly as 10%, so for instance, $19 on $190.00, a subtotal ($171, for instance) and the Tax display below at 6% of the $171 (which would be $10.26), the shipping total (let's say 25), and then a final total, which would be $206.26.

Right now if I set up the discount after tax, it adds it to the discount, making a discount of $20.14 and a tax of $11.40 rather than subtract it from the total tax. It calculates perfectly correct to $206.26, of course, but the client prefers it to display like this.

Product prices result $190
Case Discount -$19
Subtotal $171
Shipping $25
Tax $10.26
Total $206.26

Is this possible?

Sorry, should have said...working with Joomla 2.5.9 and Virtuemart 2.0.18a

Hello,

I believe what you want is actually discount before tax. Discount after tax does not discount the tax. Discount before tax does. The total will not make a difference on percentage discount, but it will on amount discounts.

That was my solution, but that's not what my client wants. With the "Calculate the discount before tax" checked to "yes" it reads:

Product prices result $119.88
Case Discount -$12.71
Shipping $27.56
Tax (6%) $7.19
Total $141.92

With the "Calculate the discount before tax" checked to "no" it reads:

Product prices result $119.88
Case Discount -$11.99
Shipping $27.56
Tax (6%) $7.19
Total $142.64

What the client wants is this:

Product prices result $119.88
Case Discount -$11.99
Subtotal $107.89
Shipping $27.56
Tax (6%) $6.47
Total $141.92

So essentially this tax is calculated off the subtotal. The total is perfectly right when it Calculates before tax...I'm just not sure how to make it display as the client wants.

Hello,

You will need to update the template to have the numbers display as you want.

The virtuemart core file is located here:
www/components/com_virtuemart/views/cart/tmpl/default_pricelist.php

If there is a template override, then it would be calling this file instead:
www/templates/[your_template]/html/com_virtuemart/cart/default_pricelist.php

You would have to update the totals to subtract as you need. You can access the coupon discounts with and without tax, like such:

Seyi,

Is this code that I could put into the default_pricelist.php or just a "for instance"? This has been the file that I've been messing about with, and I was pretty sure this is where I needed to make the changes, but being a complete and utter novice I was truly afraid I would break all calculation rules in doing so...

The code I wrote just shows you how to get access to the coupon amounts/tax. You would need to for instance, on the subtotal line, subtract the coupon without tax ($coupon_sess['product_discount_notax').
