+Request a down payment
+======================
+
+A down payment is an initial, partial payment, with the agreement that
+the rest will be paid later. For expensive orders or projects, it is a
+way to protect yourself and make sure your customer is serious.
+
+First time you request a down payment
+=====================================
+
+When you confirm a sale, you can create an invoice and select a down
+payment option. It can either be a fixed amount or a percentage of the
+total amount.
+
+The first time you request a down payment you can select an income
+account and a tax setting that will be reused for next down payments.

+It often happens that your employees have to spend their personal money
+while working on a project for your client. Let's take the example of an
+consultant paying an hotel to work on the site of your client. As a
+company, you would like to be able to invoice that expense to your
+client.
+
+Expenses configuration
+======================
+
+To track & invoice expenses, you will need the expenses app. Go to
+:menuselection:`Apps --> Expenses` to install it.
+
+You should also activate the analytic accounts feature to link expenses
+to the sales order, to do so, go to :menuselection:`Invoicing -->
+Configuration --> Settings` and activate *Analytic Accounting*.
+
+Add expenses to your sales order
+================================
+
+From the expense app, you or your consultant can create a new one, e.g.
+the hotel for the first week on the site of your customer.
+
+You can then enter a relevant description and select an existing product
+or create a new one from right there.

+Invoice based on delivered or ordered quantities
+================================================

+Depending on your business and what you sell, you have two options for
+invoicing:
+
+- Invoice on ordered quantity: invoice the full order as soon as the sales
+  order is confirmed.
+- Invoice on delivered quantity: invoice on what you delivered even if
+  it's a partial delivery.
+
+Invoice on ordered quantity is the default mode.
+
+The benefits of using *Invoice on delivered quantity* depends on your
+type of business, when you sell material, liquids or food in large
+quantities the quantity might diverge a little bit and it is therefore
+better to invoice the actual delivered quantity.

-=======================================
-How to invoice milestones of a project?
-=======================================
-
-There are different kind of service sales: prepaid volume of hours/days
-(e.g. support contract), billing based on time and material (e.g.
-billing consulting hours) or a fixed price contract (e.g. a project).
-
-In this section, we will have a look at how to invoice milestones of a
-project.
-
-Milestone invoicing can be used for expensive or large scale projects,
-with each milestone representing a clear sequence of work that will
-incrementally build up to the completion of the contract. For example, a
-marketing agency hired for a new product launch could break down a
-project into the following milestones, each of them considered as one
-service with a fixed price on the sale order :
-
--  Milestone 1 : Marketing strategy audit - 5 000 euros
-
--  Milestone 2 : Brand Identity - 10 000 euros
-
--  Milestone 3 : Campaign launch & PR - 8 500 euros
-
-In this case, an invoice will be sent to the customer each time a
-milestone will be successfully reached. That invoicing method is
-comfortable both for the company which is ensured to get a steady cash
-flow throughout the project lifetime and for the client who can monitor
-the project's progress and pay in several times.
-
-.. note::
-    You can also use milestones to invoice percentages of the entire 
-    project. For example, for a million euros project, your company 
-    might require a 15% upfront payment, 30% at the midpoint and the 
-    balance at the contract conclusion. In that case, each payment will 
-    be considered as one milestone.
-
-Configuration
-=============
-
-Install the Sales application
------------------------------
-
-In order to sell services and to send invoices, you need to install the
-**Sales** application, from the **Apps** icon.
-
-.. image:: media/milestones01.png
-    :align: center
-
-Create products
----------------
-
-In Odoo, each milestone of your project is considered as a product. From
-the **Sales** application, use the menu :menuselection:`Sales --> Products`, 
-create a new product with the following setup:
-
--   **Name**: Strategy audit
-
--   **Product Type**: Service
-
--   **Invoicing Policy**: Delivered Quantities, since you will invoice
-    your milestone after it has been delivered
-
--   **Track Service**: Manually set quantities on order, as you
-    complete each milestone, you will manually update their quantity
-    from the **Delivered** tab on your sale order
-
-.. image:: media/milestones02.png
-    :align: center
-
-.. note::
-    Apply the same configuration for the others milestones.
-
-Managing your project
-=====================
-
-Quotations and sale orders
---------------------------
-
-Now that your milestones (or products) are created, you can create a
-quotation or a sale order with each line corresponding to one milestone.
-For each line, set the **Ordered Quantity** to ``1`` as each milestone is
-completed once. Once the quotation is confirmed and transformed into a
-sale order, you will be able to change the delivered quantities when the
-corresponding milestone has been achieved.
-
-.. image:: media/milestones03.png
-    :align: center
-
-Invoice milestones
-------------------
-
-Let's assume that your first milestone (the strategy audit) has been
-successfully delivered and you want to invoice it to your customer. On
-the sale order, click on **Edit** and set the **Delivered Quantity** of the
-related product to ``1``.
-
-.. tip::
-    As soon as the above modification has been saved, you will notice 
-    that the color of the line has changed to blue, meaning that the 
-    service can now be invoiced. In the same time, the invoice status 
-    of the SO has changed from **Nothing To Invoice** to **To Invoice**
-
-Click on **Create invoice** and, in the new window that pops up, select
-**Invoiceable lines** and validate. It will create a new invoice (in draft
-status) with only the **strategy audit** product as invoiceable.
-
-.. image:: media/milestones04.png
-    :align: center
-
-.. note::
-    In order to be able to invoice a product, you need to set up the 
-    **Accounting** application and to configure an accounting journal 
-    and a chart of account. Click on the following link to learn more:
-    :doc:`../../../accounting/overview/getting_started/setup`
-
-Back on your sale order, you will notice that the **Invoiced** column of
-your order line has been updated accordingly and that the **Invoice
-Status** is back to **Nothing to Invoice**.
-
-Follow the same workflow to invoice your remaining milestones.

-How to re-invoice expenses to your customers?
-=============================================
-
-It often happens that your employees have to spend their personal money
-while working on a project for your client. Let's take the example of an
-employee paying a parking spot for a meeting with your client. As a
-company, you would like to be able to invoice that expense to your
-client.
-
-In this documentation we will see two use cases. The first, very basic,
-consists of invoicing a simple expense to your client like you would do
-for a product. The second, more advanced, will consist of invoicing
-expenses entered in your expense system by your employees directly to
-your customer.
-
-Use case 1: Simple expense invoicing
-====================================
-
-Let's take the following example. You are working on a promotion
-campaign for one of your customers (``Agrolait``) and you have to print a
-lot of copies. Those copies are an expense for your company and you
-would like to invoice them.
-

-Create product to be expensed
------------------------------
-
-You will need now to create a product called ``Copies``.
-
-From your **Sales** module, go to :menuselection:`Sales --> Products` 
-and create a product as follows:
-
--   **Product type**: consumable
-
--   **Invoicing policy**: on delivered quantities (you will manually
-    set the quantities to invoice on the sale order)
-
-.. image:: media/reinvoice02.png

-
-Create a sale order
--------------------
-
-Now that your product is correctly set up, you can create a sale order
-for that product (from the menu :menuselection:`Sales --> Sales Orders`) 
-with the ordered quantities set to 0. 
-Click on **Confirm the Sale** to create the sale
-order. You will be able then to manually change the delivered quantities
-on the sale order to reinvoice the copies to your customer.
-

-
-Invoice expense to your client
-------------------------------
-
-At the end of the month, you have printed ``1000`` copies on behalf of your
-client and you want to re-invoice them. From the related sale order,
-click on **Delivered Quantities**, manually enter the correct amount of
-copies and click on **Save**. Your order line will turn blue, meaning that
-it is ready to be invoiced. Click on **Create invoice**.
-
-.. note::
-    The total amount on your sale order will be of 0 as it is computed on 
-    the ordered quantities. It is your invoice which will compute the 
-    correct amount due by your customer.
-
-The invoice generated is in draft, so you can always control the
-quantities and change the amount if needed. You will notice that the
-amount to be invoiced is based here on the delivered quantities.
-

-
-To illustrate this case, let's imagine that your company sells some
-consultancy service to your customer ``Agrolait`` and both parties agreed
-that the distance covered by your consultant will be re-invoiced at
-cost.

-
--   Product type: Service
-
--   Invoicing policy: invoice based on time and material

-    If your product doesn't exist yet, you can configure it on the fly 
-    from the SO. Just type the name on the **product** field and click 
-    on **Create and edit** to configure it.
-
-Depending on your product configuration, an **Analytic Account** may have
-been generated automatically. If not, you can easily create one in order
-to link your expenses to the sale order. Do not forget to confirm the

-Create expense and link it to SO
---------------------------------
-
-Let's assume that your consultant covered ``1.000km`` in October as part
-of his consultancy project. We will create a expense for it and link
-it to the related sales order thanks to the analytic account.
-
-Go to the **Expenses** module and click on **Create**. Record your expense

-
-There are different kinds of service sales: prepaid volume of hours/days

-billing consulting hours) and a fixed price contract (e.g. a project).
-
-In this section, we will have a look at how to sell and keep track of a
-pre-paid support contract.
-
-As an example, you may sell a pack of ``50 Hours`` of support at ``$25,000``.
-The price is fixed and charged initially. But you want to keep track of
-the support service you did for the customer.
-
-Configuration
-=============
-
-Install the Sales and Timesheet applications
---------------------------------------------
-
-In order to sell services, you need to install the **Sales** application,
-from the **Apps** icon. Install also the **Timesheets** application if you want
-to track support services you worked on every contract.

-Create Products
----------------
-
-By default, products are sold by number of units. In order to sell
-services ``per hour``, you must allow using multiple unit of measures.
-From the **Sales** application, go to the menu 
-:menuselection:`Configuration --> Settings`.
-From this screen, activate the multiple **Unit of Measures** option.
-
-.. image:: media/support03.png
-    :align: center
-
-In order to sell a support contract, you must create a product for every
-support contract you sell. From the **Sales** application, use the menu
-:menuselection:`Sales --> Products`, create a new product with the following setup:
-
--   **Name**: Technical Support
-
--   **Product Type**: Service
-
--   **Unit of Measure**: Hours
-
--   **Invoicing Policy**: Ordered Quantities, since the service is
-    prepaid, we will invoice the service based on what has been
-    ordered, not based on delivered quantities.
-
--   **Track Service**: Timesheet on contracts. An analytic account will
-    automatically be created for every order containing this service
-    so that you can track hours in the related account.
-
-.. image:: media/support04.png
-    :align: center
-
-.. tip:: 
-    There are different ways to track the service related to a sales 
-    order or product sold. With the above configuration, you can only 
-    sell one support contract per order. If your customer orders 
-    several service contracts on timesheet, you will have to split 
-    the quotation into several orders.
-
-Note that you can sell in different unit of measure than hours, example:
-days, pack of 40h, etc. To do that, just create a new unit of measure in
-the **Unit of Measure** category and set a conversion ratio compared to
-**Hours** (example: ``1 day = 8 hours``).
-
-Managing support contract
-=========================
-
-Quotations and Sales Orders
----------------------------
-
-Once the product is created, you can create a quotation or a sales order
-with the related product. Once the quotation is confirmed and
-transformed into a sales order, your users will be able to record
-services related to this support contract using the timesheet
-application.
-
-.. image:: media/support05.png
-    :align: center
-
-Timesheets
-----------
-
-To track the service you do on a specific contract, you should use the
-timesheet application. An analytic account related to the sale order has
-been automatically created (``SO009 - Agrolait`` on the screenshot here
-above), so you can start tracking services as soon as it has been sold.
-
-.. image:: media/support06.png
-    :align: center
-
-Control delivered support on the sales order
---------------------------------------------
-
-From the **Sales** application, use the menu 
-:menuselection:`Sales --> Sales Orders`  to control
-the progress of every order. On the sales order line related to the
-support contract, you should see the **Delivered Quantities** that are
-updated automatically, based on the number of hours in the timesheet.
-
-.. image:: media/support07.png
-    :align: center
-
-Upselling and renewal
----------------------
-
-If the number of hours you performed on the support contract is bigger
-or equal to the number of hours the customer purchased, you are 
-suggested to sell an extra contract to the customer since they
-used all their quota of service.
-Periodically (ideally once every two weeks), you should check the sales
-order that are in such a case.
-To do so, go to :menuselection:`Sales --> Invoicing --> Orders to Upsell`.
-
-.. tip::
-    If you use Odoo CRM, a good practice is to create an opportunity for 
-    every sale order in upselling invoice status so that you easily track 
-    your upselling effort.
-
-If you sell an extra support contract, you can either add a new line on
-the existing sales order (thus, you continue to timesheet on the same
-order) or create a new order (thus, people will timesheet their hours on
-the new contract). To unmark the sales order as **Upselling**, you can set
-the sales order as done and it will disappear from your upselling list.
-
-Special Configuration
-=====================
-
-When creating the product form, you may set a different approach to
-track the service:
-
--   **Create task and track hours**: in this mode, a task is created for
-    every sales order line. Then when you do the timesheet, you don't
-    record hours on a sales order/contract, but you record hours on a
-    task (that represents the contract). The advantage of this
-    solution is that it allows to sell several service contracts
-    within the same sales order.
-
--   **Manually**: you can use this mode if you don't record timesheets in
-    Odoo. The number of hours you worked on a specific contract can
-    be recorded manually on the sales order line directly, in the
-    delivered quantity field.

+Expenses configuration
+======================
+
+To track & invoice expenses, you will need the expenses app. Go to
+:menuselection:`Apps --> Expenses` to install it.
+
+You should also activate the analytic accounts feature to link expenses
+to the sales order, to do so, go to :menuselection:`Invoicing -->
+Configuration --> Settings` and activate *Analytic Accounting*.
+
+Add expenses to your sales order
+================================
+
+From the expense app, you or your consultant can create a new one, e.g.
+the hotel for the first week on the site of your customer.
+
+You can then enter a relevant description and select an existing product
+or create a new one from right there.

+:menuselection:`Invoicing --> Configuration --> Settings` and select
+*Purchase Analytics*.
+
+While making the purchase order don't forget to add the right analytic
