*** Bad Bad Bad. Serious bugs. UNUSABLE ***

it's incredible that a component as an ecommerce mistakes to calculate the amounts. It may be good for websites amateur but for professional use, the problem is very serious.

I'm really disappointed because I really believe in the quality of this component and I left JOOMSHOPPING (which has many more variables and is very versatile - but I don't like the layout).
I was thinking to use HIKASHOP which is a good component, but in some cases there is much to be improved.

Returning to the topic, I have a mini shopping cart showing 170 eur

In checkout I have:
Product: 160 eur
shipping 12.60 eur
VAT (8%): 10 euro
Total amount: 182.60 (??)

In this last days I have open other discussion but are still with any answer and I don't think good.

How can I decide to buy Hikashop (Essentia/Business) if free version doesn't work fine?

Sorry but It's from 2 day ago that I'm trying to setup the component and I have don't reached any result

I set the multi-currency, but the change is correct.
I know it is a free support and no one is obliged to answer, but if I have to evaluate the purchase, you understand that it's not nice.

I didn't think having to spending so much time (because the backend is very clean and intuitive) and I'm still testing

Tax Configuration: VAT 8%
Configuration multi-currency: chf = 1 // eur = 0.84

in checkout
Unit cost: 0,16 euro
Q.ty. = 1001
Tot: 160,16 euro
Shipment: 12,60 euro
VAT: 10,01
Tot. Amount: 182,77

In minicart there is: 170,17 (seems incl. the product price + vat) but:

(160,16 + 12,60)+ VAT 8% = 186,58 and not 182,77.

I have check again. But it's wrong
I set VAT to the shipping. You wrote:
If you want the VAT to be rounded only after the price without VAT of all the products is summed, you will have to install and publish That plugin and turn off the "Display detailed tax" option in the Display tab of the configuration.

In display tab I turn off display tax display. Here the new result:

Unit price: 0.19
Q.ty: 1001

Shipment excl. VAT: 15
TAX 8%: 11.21

Total amount: 216.40

I don't understand because I really difficult to make a simple calculation.
Your result is: 216.40

My calculate is:
(0.19 x 1001)= 190,19

190,19 + 15 shipment = 205,19 + VAT 8% = 221,61

221,61 is different from your 216,40. Why?

I usually always multiplied the unit cost for the Q,ty and the tax applied only at the end. Why it's different with you?

I did as you said but I still don't understand why your component gets the wrong results.
If the tax is calculated on the unit cost or total cost, the result should not change and instead here is different.

It's incredible to discuss about this ((additions and multiplications). Calculations should be very simple and obvius.

ok ...
Can you explain me this calculation?

Unit cost: 0,19 (excl vat 8%)
Q.ty: 1002
Total: 190,38
Shipment 15 (excl. vat 8%)
VAT 8% = 11,22 (calculated on amount?)

TOTAL = 216,60

Because to me results = 221,81

Why would you immediately suspect there is an issue with Hikashop? it works fine for thousands of other people!. It seems to me that you have just not setup your shop correctly

I consider the objective facts. The amount is not correct and there is no much to configure. Only the tax and shipping charges. Nothing more.
I asked if someone can explain to me why the system returns the result above.

Unfortunately, I never thought of being stuck for nearly a week on wrong amounts. If I made a mistake, tell me where. I don't know where and what to look for ....

Surely you are just seeing the rounding of buying many thousands of products.

A single product costing 0.16 Euros at 8% VAT gives 0.0128. This is rounded to 0.01. This gives a total of 10.02 Euros and is correct under that method.

When considered against the total it is not correct due to that rounding.

Guess it depends on the accounting rules of your country and what your order quantity for small value item will typically be.

You can change to calculate on the total value of the cart which is what I would do in the UK in such a case.

However a title of ***Bad Bad Bad. Serious bugs. Unusable *** is hardly appropriate. Why not just ask how to change the calc based on total cart value?

0,16 + 8% = 0,1728
0,1728 x 1002 = 173,1456 (approx. 173,15)

About the screenshot, how is possibile that with different currency, VAT amount is always the same? Wrong ..but the same.
Is there a solution?
Usually VAT is applied at the end, as layout of checkout

Anyway this is a big problem because a customer might complain if he check the same calculation with a calculator. The amount is different.

Mathematical calculus has only one result
