Difference from invoice and cart value with coupon

Hello, I'm using version 1.5.8 with Apply discounts before tax and price_with_tax set to no tax. I configured a 50% coupon.

In checkout I correctly get:
- product 100€
- coupon 50€
- vat (20%) 10€ - correctly (100-50) * 20/100
- total 60€

But order/invoice shows:
- product 100€
- coupon 60€ (!)
- vat (20%) 20€ (!)
- total 60€

Why is there this difference? If I choose Apply discounts after tax, the order/invoice doesn't change and the checkout works as expected.
I need order/invoice and administration to be like in the checkout, how can I do that?

Thanks!

I installed version 1.5.7, then upgraded to 1.5.8.
After that, I made a small customization in templates/mytheme/html/com_hikashop/order/show.php starting from 1.5.8 file version.
I didn't create administrator/templates/bluestork/html/com_hikashop/order/invoice.php and didn't changed the original file.
I made some test checkout, but the problem is still there.
Should the problem be fixed also for old orders or just the new ones?

Thank you!!

I made some more investigation, also using your online demo. I chose Apply discounts before tax, configured a tax for Black shoes and wheel, but I got a strange behaviour: in the cart/checkout, if Show taxed prices is set to both under System-Configuration-Display the coupon is calculated on price VAT included, if it's set to No tax the coupon is calculated on price VAT excluded. It should always be VAT excluded because of Apply discounts before tax. I couldn't finish the checkout, I don't know why (click on next simply refreshed the page), so I don't know about the order/invoice.
Anyway I attached some screenshot of my environment, I made small graphical changes but it shouldn't be a problem.

It looks like it has something related to line 1150 in components/com_hikashop/controllers/checkout.php

$discount_price=@$cart->coupon->total->prices[0]->price_value_without_discount_with_tax-@$cart->coupon->total->prices[0]->price_value_with_tax;

We have the coupon discount value showing the coupon amount plus the amount that accounts for shipping and tax savings.

The end total is correct when we use a coupon, but it is confusing to our customers to see a coupon value that is higher than they are expecting to see. Also makes accounting reports difficult to figure out.

For example:

If we have a product that normally sells for $100 and a coupon for 50% off, then we want to see the coupon value displayed as $50.

Instead it shows a higher value for the coupon in to account for tax and shipping savings.

The total is correct at $50, but it is really weird to see more than $50 for the coupon total value.

Is there a way to make it so the coupon value is just $50 on a 50% discount off a product that costs $100?
We don't want shipping and tax to be figured into the coupon value that is displayed, just the 50% off the order subtotal.

Thanks.

If you can't finish an order during the checkout, you should have an error message. If you don't it's probably because of your template:

Also, it means that you either have a problem with your shipping methods or with your payment methods setup:

Could you try with that line instead:
$discount_price=@$cart->coupon->total->prices[0]->price_value_without_discount-@$cart->coupon->total->prices[0]->price_value;

I'll try and I'll let your know if it works as expected.

Thanks again!

<?php echo $this->currencyHelper->format($this->order->order_subtotal,$this->order->order_currency_id); ?>

<?php $taxes = 0;
if (/*$this->config->get('detailed_tax_display') &&*/ !empty($this->order->order_tax_info)) {
   foreach ($this->order->order_tax_info as $tax) {
      $taxes += (double)str_replace(',', '.', $this->currencyHelper->format($tax->tax_amount,$this->order->order_currency_id));
   }
}
echo $this->currencyHelper->format($this->order->order_subtotal - $taxes,$this->order->order_currency_id); ?>

I still have some problem after this change.
If I order two items:
- 100 euro, full price
- 10 euro with a 50% discount coupon (Coupon percentage applies to product only to yes)
I get:
total: 110 euro
discount: 5 euro
vat (21%): 23.1 euro (=110*0.21 instead of 22.05=105*0.21)
final: 128.1 (=105+23.1 instead of 127.05=105+22.05)

It looks like

$discount_tax = $cart->coupon->total->prices[0]->price_value_with_tax-$cart->coupon->total->prices[0]->price_value;

I still have some problem with variants using a 50% coupon.

If I choose a category in the coupon configuration, it looks like the discount for variants are calculated with this formula: price_variant * 50% + price_product.
Product: 20, you buy variant a at 20, you get 20 discount (and not 10)
Product: 20, you buy variant b at 40, you get 30 discount (and not 20)
Product: 30, you but a variant c at 170, you get 150 discount (and not 135)

If I choose a product in the coupon configuration, it looks like the discount for variants are calculated only on the price of the product.
Product: 20, you buy a variant b at 20, you get 10 discount (it's correct but the two prices are the same)
Product: 20, you buy a variant b at 40, you get 10 discount (and not 20)
Product: 30, you buy a variant c at 170, you get 15 discount (and not 135)

In both cases, I'm checking "Coupon percentage applies to product only" to yes because the discount should be applied only to the product into the selected category or variant.

Am I missing something? Thanks!!

Thank you, now coupon works properly but only if a product or category is specified.
If a coupon is for all product, the discount value is correct but VAT and total are wrong.

Example: price 100, discount 50% = -50, vat is not displayed (it's a negative value, should be 10.5) and total is 47,79 (should be 50*1.21=60,5)
The same coupon works correctly if the same product is specified in the coupon.


Would it be possible in the future to assign a coupon to a variant? And what about multiple products/variants? It would be very useful!!


Thanks again.

So that we can try to reproduce the problem.

Did you find something strange? Should I provide you more details?

Thanks!
