How can Products be added including/excluding tax?

How can Products be added including/excluding tax?

Hello,

I want to add several products to Zoho CRM and I already did define some tax rates for the products.

All products should have a tax rate of 2.5%, but the product price of all products do already include the tax (i.e. the product costs CHF 100.00 including 2.5% tax. So the product price without the tax is CHF 97.5).

So I will enter prices inclusive of tax.

Do I have to enter the product price in Zoho CRM without the tax or is there a setting, where I can say that I will enter the price inclusive of tax?

Thanks for help.
