Round TAXES on total products and not on each product

Hi,

You can do that by turning off the "Round prices during calculations" setting of the HikaShop configuration page.

I can see that you're using PayPal Checkout on your website.
In that case, you need to make sure you turn off the "send order details" setting of your payment method.
Otherwise, when PayPal calculates the total, it won't match with the total calculated by HikaShop as PayPal always calculates the total the same way as when the "Round prices during calculations" setting is turned on. And if the totals don't match, the payment won't work and the customer will get an error at the end of the checkout.
Turning off the "send order details" setting will mean that the plugin will only send to PayPal the calculated total, and not the information of each product in the order. This way, PayPal won't have to calculate anything, and no error will happen due to a total mismatch.
