I find no way to have pricelist based on cost when having prices with taxes included.

I have a product:

• price 25,

• cost 10,

• tax: 21% (included in price)

Pricelist set to Based on Cost  and the rest is left to default

I Create a Quotation and set this Pricelist, add a line with the product and get:

• unit price: 10

• cost: 10

• subtotal: 8.26

So in fact I am selling it not for cost price but for less (21% less)

What I tried is creating a Fiscal Position replacing the Tax 21% incl to Tax 21% excl

Now what I get is:

• unit price: 8.26

• cost: 10

• subtotal: 8.26

What I want is to sell it for cost price and then add the taxes on top. The standard_price in product must be tax excluded and so pricelist based on cost should behave accordingly.

How can I set my pricelist in this scenario?
