+=======================
+Use quotation templates
+=======================
+
+If you often sell the same products or services, you can save a lot of
+time by creating custom quotation templates. By using a template you can
+send a complete quotation in no time.
+
+Configuration
+=============
+
+For this feature to work, go to :menuselection:`Sales --> Configuration
+--> Settings` and activate *Quotations Templates*.
+
+.. image:: media/quote_template01.png
+  :align: center
+
+Create your first template
+==========================
+
+You will find the templates menu under :menuselection:`Sales -->
+Configuration`.
+
+You can then create or edit an existing one. Once named, you will be
+able to select the product(s) and their quantity as well as the
+expiration time for the quotation.
+
+.. image:: media/quote_template02.png
+  :align: center
+
+On each template, you can also specify discounts if the option is
+activated in the *Sales* settings. The base price is set in the
+product configuration and can be alterated by customer pricelists.

+
+Edit your template
+==================
+
+You can edit the customer interface of the template that they see to
+accept or pay the quotation. This lets you describe your company,
+services and products. When you click on *Edit Template* you will be
+brought to the quotation editor.
+
+.. image:: media/quote_template03.png

+
+.. image:: media/quote_template04.png
+  :align: center
+
+This lets you edit the description content thanks to drag & drop of
+building blocks. To describe your products add a content block in the
+zone dedicated to each product.
+
+.. image:: media/quote_template05.png
+  :align: center
+
+.. note::
+  The description set for the products will be used in all
+  quotations templates containing those products.
+
+Use a quotation template
+========================
+
+When creating a quotation, you can select a template.
+
+.. image:: media/quote_template06.png
+  :align: center
+
+Each product in that template will be added to your quotation.
+
+.. tip::
+  You can select a template to be suggested by default in the
+  *Sales* settings.
+
+Confirm the quotation
+=====================
+
+Templates also ease the confirmation process for customers with a
+digital signature or online payment. You can select that in the template
+itself.
+
+.. image:: media/quote_template07.png
+  :align: center
+
+Every quotation will now have this setting added to it.
+
+Of course you can still change it and make it specific for each
+quotation.
