Hello I need to modify my admin side product pricing.. I need two different prices to calculate my product's selling price. the default price panel has those; Pre-tax wholesale price Pre-tax retail price Tax rule: Retail price with tax Unit price what i need here; Pre-tax wholesale price: 250 Pre-tax retail price: 400
Pre-tax custom price: 100 Tax rule: %18
Custom price with tax: 118
Retail price with tax= "Pre-tax retail price" + "Custom price with tax" : 518 Unit price
So i need to apply tax for only custom price and sum it with retail price that doesn't have tax included. Also need to show that pricing on invoice, too.
How could i modify my site's tpl files or what do i need for that customization?
