Inventory valuation configuration
=================================

Inventory valuation refers to how you value your stock. It’s a very
important aspect of a business as the inventory can be the biggest asset
of a company.

Inventory valuation implies two main choices:

-  The cost method you use to value your goods (standard, fifo, avco)
-  The way you record this value into your accounting books (manually or automatically)

Those two concepts are explained in the sections below.

Costing Methods: Standard, FIFO, AVCO
=====================================

The costing method is defined in the product category. There are three
options available. Each of them is explained in detail below.

       - €40

  In **Standard Price**, any product will be valued at the cost that you defined
  manually on the product form. Usually, this cost is an estimation based
  on the material and labor needed to obtain the product. This cost must
  be reviewed periodically.

       - €9
       - 4
       - +2*€6
       - €36

  In **AVCO (Average Cost)**, each product has the same value and this 
  value is the average purchase cost of the product. With this costing method, the
  cost of the product is recomputed as each receipt.

  The average cost does not change when products leave the warehouse.

  In **FIFO (First In First Out)**, the products are valued at their
  purchase cost. When a product leaves the stock, that’s the “First in, 
  first out” rule that applies.
  
  Pay attention, that this is a financial FIFO. The first value “in” 
  is the first value “out”, no matter the storage location, warehouse
  or serial number.

  FIFO is advised if you manage all your workflows into Odoo (Sales, 
  Purchases, Inventory). It suits any kind of users.

Inventory Valuation: Manual or Automated
========================================

There are two ways to record your inventory valuation in your accounting
books. As the costing method, this is defined in your product category.
Those two methods are detailed below.

It is important to also note that the accounting entries will depend on
your accounting mode: it can be continental or anglo-saxon. In
continental accounting, the cost of a good is taken into account as soon
as the product is received in stock. In anglo-saxon accounting, the cost
of a good is only recorded as an expense when this good is invoiced to a
final customer. In the tables below, you can easily compare those two 
accounting modes.

Usually, based on your country, the correct accounting mode will be
chosen by default. If you want to verify your accounting mode, activate
the developer mode and open your accounting settings.

Manual Inventory Valuation
--------------------------

In this case, goods receipts and deliveries won’t have any direct impact
on your accounting books. Periodically, you create a manual journal
entry representing the value of what you have in stock. To know that
value, go in Inventory > Reporting > Inventory Valuation.

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.

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.

Create a journal entry to move the stock variation value from your 
Profit&Loss section to your assets.

  If the stock value decreased, the **Inventory** account is credited
  and te **Inventory Variations** debited.

Automated Inventory Valuation
-----------------------------

In that case, when a product enters or leaves your stock, an accounting
entry will be automatically created. This means your accounting books
are 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.

First, you need to define the accounts that will be used for those
accounting entries. This is done on the product category.
