Wrong tax calculation in point of sale (POS)

[Similys]

In the point os sale, the calculated tax is wrong.

By default, a class of tax has an option to say if it's calculation implies that the base price is including tax, or excluding tax.

When I create a sale order from the normal sale screen, I buy a PC1 with 21 of VAT, the total price is 544,50 EUR, with 94,50 EUR of VAT.

When I do the same order from the point of sale, I get a total price of 450 EUR, with 78,10 EUR of VAT !

Of course, all reports are wrong too.

In the code, module point_of_sale -> pos.py
 in class pos_order, the method _amount_tax

=> the code calls compute_inv method from account.py, which computes prices just like the base price is always VAT included.

A quick question / guess:
Have you tried to install the extras module 'sale_tax_include'? The tax included option only works for sale orders when it is installed.

[Similys (openerp-similys)]

point_of_sale has a dependency on sale_tax_include, so the module has it already by default.

Hello Similys,

There are quite a few issues with the 'certified' Point of Sale module. It doesnt work as you would expect and I personally never advice the use of the module because it creates a different object other than sale to record sales.

And this object unfortunately is rarely handled in other parts of the system like 'sale' is.

If i remember there are quite a few issues with accounts postings and invice conversions too.

Try the sale_simple_pos module (http://doc.openerp.com/technical_guide/sale_simple_pos.html) if what you are looking for is simplification of sales process

You can't try also POS_extension from extra-addons. We've got a couple of implementations and it's working as it should be.

Hello Similys,

I have tested your scenario in updates code. And it works fine in both module sale and point_of_sale.and you need to give the tax in product while making a sale order in point_of_sale module.I have attached the screen shots of both sale orders.

Thanks.

In trunk : Total and Subtotal(Order Lines) is not calculate properly If the tax is included in price.

Thanks.
