Why is it not possible to add tax? Is that not a demand for every contry?, when deling with b2b customers it is requried that the orderform is showing the taxes as a seperat line.
At least here in denmark
previous versions had a plugin for tax, but not version 3.0?
we have a law in here, that all prices for the customers must be displayed as full price, tax already included -- that's why it is generally not neccessary to have two prices displayed with your product.
However, if you really need to display the price with and without tax, I am able to implement it for you into QC 3.0, for a small fee. The editing is quite elaborating, so I prefer to do it myself, instead of just selling you my notes on how to do it (you will get the notes too, though). The neccessary changes include editing styles, templates, JavaScript and also QC code -- it's not a "plugin" style type of thing.
Peterfam, if you're interested, go here http://www.nlp.sk/antispam/ and write to my e-mail address displayed on that site. I'll then show you a demo of what you can get and we'll work out the exact solution for you. I think I already have done what you need, that's why my programming fee will be minimal, all you need is just to set it up.
