prestashop税收行为,如何申请纳税?

I have problem to add taxes in my project..

I want to add first excise duty as 12% to my product.

And then Apply vat as 5% on total amount.

In product pries we can apply only one tax. How should i do this ?

I tried one after another Behavior but applying one tax who should i can apply another tax.

i promise you you can apply tax calculations on a certain amount multiple times. if i am selling an item that cost me $100 to make and I add tax of 20% for profits the price would then be $120.If I then include 5% vat it would be 120*(100+5)/100 which is 126. Good luck
