B2B buying cost price VAT ex. and RRP VAT inc. double display

[Thomas Bk]

Hi all,

I'm actively searching for a module that could help me display the following: 

• B2B buying cost price VAT ex.
• B2C RRP VAT inc. double display

I'm selling products only to B2B shops therefore they need to see straight away their own purchasing price without VAT AND the RRP retail recommanded price that they will apply for their own end consumers. 

This double pricing display would need to be live in all "pricing blocks" (page list, product page, cart, invoice, etc).

Also, I saw on competitor B2B websites (using another solution than Prestashop I guess) the possibility to display or not the B2B buying cost price VAT ex. by just clicking a button placed in the header of their website. This allow my clients to show the products on their computer when in shops to end consumers without revealing their own purchasing price. Otherwise this could create some unconfortable situations... 

Spent quite some time looking for such a module but didn't find it! 

Could someone help?

Thanks and good day!

Thomas
