==========================================================
How to do an inventory valuation? (Anglo-Saxon Accounting)
==========================================================
==========================================================
Costing Method
==============
Every year your inventory valuation has to be recorded in your
balance sheet. This implies two main choices:
- the way you compute the cost of your stored items
(Standard vs. Average vs. Real Price);
- the way you record the inventory value into your books
(periodic vs. Perpetual).

**Standard Price** means you estimate the cost price based
on direct materials, direct labor and manufacturing overhead
at the end of a specific period (usually once a year). You
enter this cost price in the product form.

The **Average Price** method recomputes the cost price as a
receipt order has been processed, based on prices defined in
tied purchase orders. This method is mainly justified in case
of huge purchase price variations and is quite unusual due to
its operational complexity. Your actually need a software like
Odoo to keep this cost up-to-date.
This method is dedicated to advanced users. It requires well
established business processes because the order in which you
process receipt orders matters in the cost computation. Moreover
if you mistakenly process such an order, there is no way to
reset the cost price at its initial value.
FIFO

For **Real Price** (FIFO, LIFO, FEFO, etc), the costing is
further refined by the removal strategy set on the warehouse
location or product's internal category. The default strategy
is FIFO. With such method, your inventory value is computed
from the real cost of your stored products (cfr. Quantitative
Valuation) and not from the cost price shown in the product
form. Whenever you ship items, the cost price is reset to the
cost of the last item(s) shipped. This cost price is used to
value any product not received from a purchase order (e.g.
inventory adjustments).
Such a method is advised if you manage all your workflow into
Odoo (Sales, Purchases, Inventory). It suits any kind of users.
LIFO (not accepted in IFRS)

Odoo allows any method. The default one is **Standard Price**.
To change it, check **Use a 'Fixed', 'Real' or 'Average' price
costing method** in Purchase settings. Then set the costing
method from products' internal categories. Categories show up
in the Inventory tab of the product form.
Whatever the method is, Odoo provides a full inventory valuation
in :menuselection:`Inventory --> Reports --> Inventory Valuation`
(i.e. current quantity in stock * cost price).
Periodic Inventory Valuation
============================
In a periodic inventory valuation, goods reception and
outgoing shipments have no direct impact in the accounting.
At the end of the month or year, the accountant posts one
journal entry representing the value of the physical inventory.
This is the default configuration in Odoo and it works
out-of-the-box. Check following operations and find out how
Odoo is managing the accounting postings.

============================= ===== ======
\ Debit Credit

Assets: Inventory 50
Assets: Deferred Tax Assets 4.68
Liabilities: Accounts Payable 54.68
============================= ===== ======
Configuration:
* Purchased Goods: defined on the product or on the internal category of related product
(Expense Account field)
* Deferred Tax Assets: defined on the tax used on the purchase order line
* Accounts Payable: defined on the vendor related to the bill
Goods Receptions

Configuration:
* Revenues: defined on the product or on the internal category of related
product (Income Account field)
* Deferred Tax Liabilities: defined on the tax used on the invoice line
* Accounts Receivable: defined on the customer (Receivable Account)
The fiscal position used on the invoice may have a rule that replaces the
Income Account or the tax defined on the product by another one.

At the end of the month/year, your company does a physical inventory
or just relies on the inventory in Odoo to value the stock into your books.
Then you need to break down the purchase balance into both the inventory and
the cost of goods sold using the following formula:
Cost of goods sold (COGS) = Starting inventory value + Purchases – Closing inventory value
To update the stock valuation in your books, record such an entry:
.. h:div:: doc-aside
.. rst-class:: values-table
===================================== ===== ======
\ Debit Credit
===================================== ===== ======
Assets: Inventory (closing value) X
Expenses: Cost of Good Sold X
Expenses: Purchased Goods X
Assets: Inventory (starting value) X
===================================== ===== ======
Perpetual Inventory Valuation
=============================
In a perpetual inventory valuation, goods receptions and
outgoing shipments are posted in your books in real time.
The books are therefore always up-to-date. This mode is
dedicated to expert accountants and advanced users only.
As opposed to periodic valuation, it requires some extra
configuration & testing.
Let's take the case of a reseller.

**Configuration:**
- Accounts Receivable/Payable: defined on the partner (Accounting tab)
- Deferred Tax Assets/Liabilities: defined on the tax used on the
invoice line
- Revenues/Expenses: defined by default on product's internal category
and can be set in product form (Accounting tab) as a specific replacement
value
- Goods Received Not Purchased: to set as Stock Input Account in product's
internal category
- Goods Issued Not Invoiced: to set as Stock Output Account in product's
internal category
- Inventory: to set as Stock Valuation Account in product's internal category
- Price Difference: to set in product's internal category or in product
form as a specific replacement value
