Separate VAT for attributes and main product

[digital]

I am looking for someone that can help me to modify Prestashop according to the following descripton:

 

I am selling products with many different attributes. I want to be able to set different VAT levels for each of the attributes and the main product separately.

 

The main product should have one VAT level (shop default, e.g. 20%), and all the attributes should have either the same VAT or 0% VAT.

 

The correct total VAT needs to be specified on the invoice.

 

Example:

 

Product A cost 100 euro, plus 20% VAT.

The added attributes cost 100 euro extra, but 0% VAT.

Total price is 100*1.2+100 = 220 euro. 200 excl VAT plus 20 euro VAT.

 

The reason for this is that the attributes are tax free but the main product is our service charge, which must be taxed.

 

Prestashop version is 1.5.6.2.

 

Time frame: Within two weeks

 

The modification must be compatible and work together with our addon modules, such as payment modules etc.

 

Please feel free to ask me anything if you have any questions about this job.

Attributes are meant to slightly specify the product, like color, size, and so on. The core of the product must stay and tax rate is deeply rooted to the product itself.

 

I think you should find a different approach, because it is almost impossible to do what you want.
