Define product prices for Business to Customer (tax included)

In most countries, business to customers prices are tax-included. Check Included in Price for each of your sales taxes in Accounting / Configuration / Taxes.

This way the price set on the product form includes the tax. As an example, let’s say you have a product with a sales tax of 10%. The sales price on the product form is $100.

If the tax is not included in the price, you will get:

Price without tax	$100
Taxes	$15
Total to pay	$115

If the tax is included in the price:

Price without tax	$86.96
Taxes	$13.04
Total to pay	$100
