Account tax amount per product variant
32+
======================================
33+
34+
While managing fixed tax amount, sometime we want to use a differnt
35+
amount for each variant of a product. To handle this, we use the amount
36+
type ``fixed`` and add a new setting **use product amount** to tell the
37+
system to use the amount from the product variant. If not set (equals to
38+
0), the tax amount is computed as usual taking information from the tax.
39+
40+
Features:
41+
42+
- multiple tax amount per product variant (one per tax)
43+
- multi-company support
44+
- compatible with sale, purchase, invoicing, website sale
45+
46+
..
47+
48+
**Note**: This module can be use to handle ecotax that differs from
49+
other modules in this repository:
50+
51+
- ``account_ecotax``: which do not rely on tax wich is hard to use
52+
differnt accounts and requires an odoo module for sale,purchase,
53+
account, pos, etc.
54+
- ``account_ecotax_tax``: which rely on ``account_tax_python`` but do
55+
not allow to use multiple tax amount for a single variant and also
56+
depends on the ``account_ecotax`` modules which makes the whole
57+
module less flexible.

Configuration
65+
=============
66+
67+
To configure this module, you need to:
68+
69+
- Setup specific accounts for your taxes or decide which account will be
70+
used for all taxes.
71+
72+
- Create a tax with amount type ``fixed`` and set the
73+
``use_product_amount`` to ``True``. Other settings behave as usual.
74+
75+
- Configure the tax on product template this will generate all the tax
76+
amount for each product variant using default values set on the tax.
77+
78+
- Configure the tax on product variant form view or in the Accounting >
79+
Configuration > Accounting > Tax > Product Amounts menu.
80+
81+
**EcoTax example :**
82+
83+
In france eco tax is a fixed tax amount that depends on product variant
84+
caractersistics.
85+
86+
If you are selling sofa that contains electronics, you will have two
87+
different tax amount for the same product variant: one for the sofa and
88+
one for the electronics.
89+
90+
While you purchase goods eco tax is not computed as VAT this are expense
91+
that are added to the price. So we advise you to use a dedicated account
92+
in ``607`` for each tax collector to properly follow and manage your eco
93+
taxes.
94+
95+
Same for sale, you can use a dedicated account in ``707`` as the ecotax
96+
is part of your income.
97+
98+
Also the VAT amount is computed on the product variant base price plus
99+
the ecotax amount so you needs to tick the
100+
``Affect Base of Subsequent Taxes`` to ``True`` and ensure the tax is
101+
properly sorted in the tax sequence.
102+
103+
So when you sell a product variant with a base price of 10.00€ with an
104+
ecotax amount of 1.50 and a VAT of 20%. The final price will be 10.00€
105+
(base price) + 1.50€ (ecotax) + 2.30€ (VAT: 11.50€ \* 20%) = 13.80€
106+
107+
You could get the following journal items:
108+
109+
- credit 10.00€ (base price) -> 7070 (income)
110+
- credit 1.50€ (ecotax) -> 7071 (eco tax income)
111+
- credit 2.30€ (VAT) -> 445 (VAT tax)
112+
- debit 13.80€ (total to pay) -> 411 (partners receivable account)
113+
114+
Usage
115+
=====
116+
117+
Once you have setup account, tax and product, you can use product
118+
variant as usual in invoice, sale, purchase, etc.
119+
120+
Known issues / Roadmap
121+
======================
122+
123+
- Allow to set the tax amount from the product template view when there
124+
is only one variant.
125+
- implement account_tax.js to handle the tax amount in pos and create a
126+
glue module (such as ``pos_tax_product_amount``) to handle tax product
127+
amount in pos.
128+
