3. Taxes¶
As a general rule, the unit price of a product, shall always contain the net price. When our
products show up in the catalog, their method get_price(request)
is consulted by the framework.
Its here where you add tax, depending on the tax model to apply. See below.
3.2. Other considerations¶
Try to not reinvent the wheel: Other shop systems / frameworks will contain solutions to this problem. But also ERP-Systems will contain solutions to this problem.
Maybe it is wise to have a look at projects like Tryton (http://tryton.org).
