Hello Team

I need help configuring two sales taxes. **VAT** (19.25%) and **DOP** (Deduction on purchase)

**DOP** is apply on a specific activity where a certain percentage is added on the Price excluding Tax (just like the VAT).

The challenge is that the **DOP may take five (5) different values** (10%, 5%, 2.5%, 2% and 1%) depending on the customer type of company.

1. How to configure it for it to run automatically

We then want to the final amount All Tax Included (ATI) to be displayed in front of the product line. This ATI amount = Price excluding VAT x (1 + VAT + TSP). The final amount is therefore ATI.

1. How do I configure it?

Thank you for your kind help.
