+
+The *Account Product Module* mainly extends existing accounting and product
+concepts.
+
+.. _concept-product:
+
+Product
+=======
+
+The *Product* concept is extended with a set of methods that allow access to
+the product's accounting related properties.
+
+Many of these properties are set in the product's accounting category.
+The accounting category is a special type of
+`Product Category <model-product.category>`.
+Unlike standard product categories, each product can only have a single
+accounting category.
+
+.. seealso::
+
+   The `Product <product:concept-product>` concept is introduced by the
+   :doc:`Product Module <product:index>`.
+
+.. _model-product.category:
+
+Product Category
+================
+
+The *Account Product Module* allows some *Product Categories* to be marked as
+accounting categories.
+These product categories can have accounting properties such as
+`Taxes <account:model-account.tax>`, and revenue and expense
+`Accounts <account:model-account.account>` associated with them.
+
+When placing categories into a structure all the categories in the structure
+must be either standard categories or accounting categories.
+This means an accounting category cannot have a standard category as its
+parent or as any of its subcategories.
+
+.. seealso::
+
+   The `Product Category <product:model-product.category>` concept is
+   introduced by the :doc:`Product Module <product:index>`.
+
+.. _model-analytic_account.rule:
+
+Analytic Account Rule
+=====================
+
+The *Account Product Module* extends the *Analytic Account Rules* allowing
+`Products <concept-product>` and `Categories <model-product.category>` to be
+used as criteria by the analytic rule engine.
+
+.. note::
+
+   This feature is only available when the *Analytic Account Module* is
+   activated.
+
+.. seealso::
+
+   The `Analytic Account Rule <analytic_account:model-analytic_account.rule>`
+   concept is introduced by the
+   :doc:`Analytic Account Module <analytic_account:index>`.

 Account Product Module
 ######################
 
-The account product module adds accounting on product and category.
+The *Account Product Module* allows products to be associated with accounting
+properties such as taxes and expense or revenue accounts.
+It allows these properties to be easily managed using accounting categories.
 
-.. note::
-    If the analytic account module is activated, it also adds the product and
-    category as criteria for the analytic rule engine.

+Usage
+*****
+
+.. _Using product accounting categories:
+
+Using product accounting categories
+===================================
+
+You set the accounting properties of a `Product <concept-product>` in the
+product's accounting `Category <model-product.category>`.
+You can only use product categories that have been specifically marked as
+accounting categories for this.
+
+How you decide to structure your accounting categories is very dependent on
+what your products are, and how you want to group and manage them.
+
+In a clothes company you may have some accounting categories for::
+
+   Clothes
+      Shirts
+         Children
+         Adults
+   Shoes
+      Children
+      Adults
+
+If you were using this structure then you could define different rates of
+:abbr:`VAT (Value Added Tax)`, or :abbr:`GST (Goods and Services Tax)`,
+for children's and adults' items.
+It would also allow you to define different revenue
+`Accounts <account:model-account.account>` for the revenue generated from the
+sales of clothes and the revenue generated by selling shoes.
