+================
+Price management
+================
+
+Odoo offers multiple options to select the price displayed on your website, as well as
+condition-specific prices based on set criteria.
+
+Taxes
+=====
+
+Tax configuration
+-----------------
+
+To add a tax on a product, you can either set a tax in the :guilabel:`Customer Taxes` field of the
+**product template** or use
+:doc:`fiscal positions </applications/finance/accounting/taxation/taxes/fiscal_positions>`.
+
+.. seealso::
+   - :doc:`/applications/finance/accounting/taxation/taxes/taxes`
+   - :doc:`/applications/finance/accounting/taxation/taxes/avatax`
+   - :doc:`/applications/finance/accounting/taxation/taxes/taxcloud`
+   - :doc:`/applications/finance/accounting/taxation/taxes/fiscal_positions`
+
+Tax display
+-----------
+
+Choosing the displayed price tax usually depends on a country's regulations or the type of customers
+**(B2B vs. B2C)**. To select the type of price displayed, go to :menuselection:`Website -->
+Configuration --> Settings`, scroll down to the :guilabel:`Shop - Products` category, and select
+:guilabel:`Tax Excluded` or :guilabel:`Tax Included`.
+
+- :guilabel:`Tax Excluded`: the price displayed on the website is **tax-excluded**, and the tax is
+  computed at the cart-review step;
+- :guilabel:`Tax Included`: the price displayed on the website is **tax-included**.
+
+.. note::
+   This setting is **global**, and the tax-display type is the same for (all of) your website(s). It
+   is, therefore, not possible to select different tax displays for different websites. This may be
+   a significant point of consideration when implementing a database with multiple ecommerce
+   websites aimed at varying customer types (i.e., B2B and B2C).
+
+You can choose to display the type of pricing next to the product price by going to
+:menuselection:`Website --> Site --> Homepage --> Shop`, selecting a product, and then
+:menuselection:`Edit --> Customize tab` and enabling :guilabel:`Tax Indication`.

+
+Price per unit
+==============
+
+It is possible to display a
+:doc:`price per unit </applications/inventory_and_mrp/inventory/management/products/uom>` on the
+product page. To do that, go to :menuselection:`Website --> Configuration --> Settings` and enable
+:guilabel:`Product Reference Price` under the :guilabel:`Shop - Products` section. When enabled,
+ensure an amount is set in the :guilabel:`Base Unit Count` field of the **product template**, and in
+the :guilabel:`Sales Price`.
+
+.. image:: price_management/price-cost-per-unit.png
+   :align: center
+   :alt: Cost per unit pricing on the product template
+
+The price per unit of measure can be found above the :guilabel:`Add to Cart` button on the product
+page.
+
+.. image:: price_management/price-cost-per-unit-page.png
+   :align: center
+   :alt: Cost per unit pricing on the product page
+
+.. note::
+   Pay attention that having the price per unit may be **mandatory** in some countries.
+
+.. seealso::
+   :doc:`/applications/inventory_and_mrp/inventory/management/products/uom`
+
+Price configuration: pricelists
+-------------------------------
+
+Pricelists are the primary tool to manage prices on your eCommerce. They allow you to define
+website-specific prices - different from the price on the product template - based on the **country
+group**, **currency**, **minimum quantity**, **period**, or **variant**. You can create as many
+pricelists as needed, but it is mandatory to have at least one pricelist configured per website. If
+no custom pricelists are added, Odoo defaults to the **Public Pricelist** for all websites.
+
+.. seealso::
+   :doc:`/applications/sales/sales/products_prices/prices/pricing`
+
+Configuration
+~~~~~~~~~~~~~
+
+Pricelists can be found under :menuselection:`Website --> eCommerce --> Pricelists`, but must first
+be activated. For that, head to :menuselection:`Website --> Configuration --> Settings` and scroll
+down to the :guilabel:`Shop - Products` section. There, you can find two options:
+
+- :guilabel:`Multiple prices per product`;
+- :guilabel:`Advanced price rules (discounts, formulas)`.
+
+The **first** option allows you to set different prices per customer *segment*, i.e., registered
+customers, gold customers, regular customers, etc. The **second** option allows you to set *price
+change* rules such as **discounts**, **margins**, **roundings**, etc.
+
+Foreign currency
+~~~~~~~~~~~~~~~~
+
+If you are selling in **multiple currencies** and have pricelists in foreign currencies, customers
+can select their corresponding pricelist anywhere on the :guilabel:`Shop` page from the drop-down
+menu next to the **search bar**.

+
+Permanent discount
+------------------
+
+If you have permanently reduced the price of a product, a popular means to attract customers is the
+**strikethrough** strategy. The strategy consists in displaying the previous price crossed out and
+the **new discounted price** next to it.
+
+.. image:: price_management/price-strikethrough.png
+   :align: center
+   :alt: Price strikethrough
+
+To display a 'striked' price, enable the :guilabel:`Comparison Price` option under
+:menuselection:`Website --> Configuration --> Settings --> Shop - Products category`. Then, head to
+the product's template (:menuselection:`Website --> eCommerce --> Products`), and in the
+:guilabel:`Compare to Price` field, enter the **new** price.
