Hi,
I have installed the Edit orders mod and have basically 2 tax classes at 4% and 12.5%.
When I click on the details button and then update the order. The order total is affected as now the 2 differnt tax amounts calculated at 4% and 12.5% for different items get added up and I basically get 2 tax amounts equal to 4+12.5=16.5% whereby making the order total incorrect. The pics below show the actual invoice and then the invoice after I update. Please help
Unfortunately, edit orders does not support multiple taxes. You can lump your two taxes together and it will work fine. Otherwise, edit orders is not for you.

ferid -- I've read the post over several times now that you made, and I must admit, I still don't get it. How is it possible that you subtotal is less than one of your items? Did you use a coupon or something? But...usually coupons happen after the subtotal and are reflected in the total....I just don't get it.
Anyway, regardless, I think I can clear up how taxes work:
Each item is assigned its own tax rate for an order. So, each item is calculated for that tax rate. The subtotal is completely ignored as far as taxes are concerned. Something is causing your subtotal to be less than the cost of the item. Hence, edit orders is calculating the tax based on your item NOT the subtotal. It does this so that you can charge different tax rates for different items. (Of course, the total tax is lumped together as one tax below the subtotal no matter how many tax rates you have. Hence the earlier problem in this thread where someone wanted to separate taxes into two line items instead of one.) I believe that is the problem you are having. This is how the mod was designed to work -- v1 and v2 both do this.
I think this example will help many people who are having tax issues. There is no perfect way to deal with taxes when editing an order -- so sacrifices have to be made. The way Zen Cart was designed orders were not meant to be edited, so edit orders has to take some liberties. Here's an example of how this works:
Notice that the two taxes take the same value -- the total tax for the order. Also notice that the coupon and subtotal have no effect on taxes. If you want this scenario to work, you'd need to do the following:
Item A $85 @ 15% Tax = $12.75 Tax (Instead of coupon, subtract $15 from item. Then, it applies taxes based on that tax rate!)
Item B $200 @ 20% Tax = $40 Tax
Subtotal: $285 (Subtotal changes because price of item changed.)
Coupon NONE
Tax: $10 @ 10% Tax = $1 Tax
Tax All VAT Combined: $53.75 (Only one tax type is defined that combines all taxes, no matter what rate, together.)
Notice, this works much better because the coupon is folded into an item, and then takes that items tax rate. Plus, only one tax is defined that acts as a catch all for ALL taxes.
You can easily see the dilemmas with edit orders --- which items fall under what tax rates? Where do these taxes go, the first or second tax type? What tax rate do coupons take? Etc.... Much of this data is not stored in the database once an order is placed -- Zen Cart is really not designed to edit orders. Hence, there is no perfect solution. Edit orders strives to do its best, but it will not work correctly in all situations. The more conventional and simple you situation is, the more likely everything will work fine with tax calculations. If not, you may have to figure workarounds out like I did here if you want to use edit orders. If you have more than one tax line for an order -- it simply won't work at all. Edit orders was designed for one tax line per order. Hope this explanation helps!
Thank you for your reply.
I don't use coupons and only one tax rate (19%).
The item total you see in all three cases is inc. tax. The subtotal in the first case is also inc. tax. But the other two examples, where the subtotal is lower than the item total, the subtotal shows ex tax. This happens as soon as I edit a order. I don't know why.
If you calculate 0,85*1,19=1,01
The shipping costs (standaard), €1,00 is show inc. tax. The module shouldn't calculate 19% over the €1,00 (1*0,19) but should calculate the tax that is in €1,00: 1/1,19*0,19
Maybe I am seeing this all wrong or I just don't get it...
If you go to my store-> configuration, there is an option called display prices with tax. If you set it to false, product prices, sub-total and shipping rate will be shown without tax. If you set it to true (in my case) al these prices will be shown with tax. So looks like this is normal.
Can someone confirm this?
OK, well you've answered your question then! I'm always amazed by the different features I discover in Zen Cart.
This mod was designed to work in the default way with Zen Cart, which is to set the setting you just described to false. You'll need to set it to false for this mod to work right.
