Looking for module (Product Cost + Price For customer groups)

Hi all

i am looking for a module that can do this

Product Cost-----> Customer Group %----->(Including tax) Rounding to 0,05----->Customer Price

Customer Group 1 +25%
Customer Group 2 +40%
Customer Group 3 +60%
etc.


so if product cost is 50,45 (ex tax) and Customer Group is 2 the price ex tax is 70,63 in my country we have 6% or 21% tax so i use 21% the price wil be 85,4623 now are including the rounding the product price wil be 85,50


Who can help me to make this work or now's a module that does this

Best Regards Sijmen

As per my understanding you need like this functionality:
1. if you have a product abc and product price is 100$
2. you some customer group like customer group 1, customer group2
customer group 1 have 20 % tax
customer group 2 have 25 % tax
3. When the customer is loged-in that have the customer group 1 then the product price should be 125$

I can do like this functionality but for this functionality I need to create a module and also I need to use the vqmod or OCMOD. So kindly update me which overwrite method I use for this. I can manage by anyone.

no not tax but a reduction on price for lets say wholesale customer and normal customer

ocmod or vqmod is no problem i have both
