+Add subscription products
+=========================
+
+To properly sell your subscriptions using our amazing **Odoo Subscriptions** application, you must follow
+these steps:
+
+1. **Create your own subscription templates**
+2. **Create your own subscription products with the right settings**
+
+As a result, you will be able to manage your subscriptions like any other product, create your
+quotations and continue the sales flow to track the number of subscriptions you sell and manage the
+revenue they generate.
+
+Configuration
+=============
+
+Go to :menuselection:`Subscriptions --> Subscription products` to learn how you can configure your
+own subscription products. You have the possibility to create a new product or edit an existing one.
+Once named, be careful to select the option *Can be sold* and deselect *Can be purchased*. For the
+product type, it is recommended to use *Service* for subscription products as they are non-material
+products that you provide to your customers. Finally, you can adapt your prices and also add an
+internal reference.

+==========================
+Use subscription templates
+==========================
+
+The subscription business model is becoming more popular. Are you wondering why?
+
+- For **customers**, value lies in **convenience**:
+
+  - Subscriptions simplify the business process. Indeed, subscribers never have to remember to renew
+    their orders every month, which gives them the assurance that they will have everything they
+    need before they actually need it.
+  - Subscriptions help customers stay on budget.
+
+- For **businesses**, value lies in the **ability to predict recurring revenue**:
+
+  - Subscriptions reduce customer churn rate and significantly increase customer retention.
+  - Subscriptions provide much higher payment security for your business. They stabilize and
+    maintain recurring revenue streams by guaranteeing monthly revenues and adding value to your
+    business.

+
+**Odoo Subscriptions** help you save time and money. Subscription templates can help you generate
+recurring invoices and manage renewals at a fast pace. With Odoo you have the possibility to create,
+edit, and manage your own subscription templates.
+
+Configuration
+=============
+
+Go to :menuselection:`Subscriptions --> Configuration --> Subscription templates`. By default, Odoo
+suggests you two types of subscription (MON - Monthly subscription *vs* YEA - Yearly subscription).
+You can also create your own ones.
+
+.. image:: media/subscription_templates_1.png

+
+.. important::
+   The **Odoo Subscriptions** application automatically installs **Odoo Sales** and **Odoo Invoicing**
+   as they work integrated.
+
+Create your first template
+==========================
+
+You can create a new template or edit an existing one. The first thing you need to do is give your
+template a name. After that, choose an *Invoicing period* and specify whether you would like to
+invoice your customers per *Days*, *Weeks*, *Months* or *Years*. On *Duration*, determine if
+the subscription must go on *Forever* (until it’s manually closed), or for a *Fixed amount* of time.
+Among the payment options, an additional field called *Invoice email* appears when you choose
+*Send*, *Send & try to charge* or *Send after successful payment*. This field allows you to add an
+invoice email template to your subscription templates.
+
+.. image:: media/subscription_templates_2.png
+  :align: center
+  :alt: Create your own subscription templates on Odoo Subscriptions
+
+For each template, you can also choose if you want your customers to be able to close their
+subscriptions or not. If enabled, you can set an *Automatic closing* limit and specify the
+*Group of subscription* and *Journal* options.
+
+.. note::
+   On each template, you can add your **Terms and Conditions**. Specifying terms and conditions is
+   essential to set out important contractual points between the customers and the sellers (payment,
+   refund policy, cancellation, complaints, etc.).
+
+   .. image:: media/subscription_templates_3.png

+
+   Finally, if you want to know the basic running health status of your subscriptions, you also have
+   access to a specific tab called **Health Check**. There, you can edit and create your own
+   filters to define what is a subscription in good health *vs* bad health. The system automatically
+   summarizes all the records corresponding to these filters and you are able to manage them in one
+   click.

+Discover our subscription reports
+=================================
+
+As we now know well enough, understanding how our business is going and where it is going is the key
+to success. This is even more the case when we offer subscription services or products.
+
+Before getting to the heart of the matter, it is very important to recall certain concepts essential
+to the proper understanding of the following reports:
+
+- **Monthly Recurring Revenue (MRR)**: MRR is arguably the most important metric for subscription
+  businesses. Indeed, it shows the revenue earned with subscription-based products or services every
+  single month. It is a consistent number that you can use to track all your recurring revenue over
+  time, in monthly increments.
+
+- **Annual Run-Rate (ARR)**: ARR is the yearly version of MRR. Based on the current MRR, you can estimate
+  the coming year's performance with the Annual Run-Rate. However, this estimation does not take
+  variations and growth into account.
+
+.. image:: media/reports_1.png
+  :align: center
+  :alt: Difference between MRR and ARR in Odoo Subscriptions
+
+- **Non-Recurring Revenue (NRR)**: NRR shows the revenue earned for everything else than subscription-based
+  products or services. This includes gains of a rare or unique nature that are unlikely to occur in
+  the ordinary course of businesses.
+
+- **Customer Retention**: This concept consists of engaging existing customers to continue buying
+  products or services from your business. As you may know, customer retention is quite a challenge
+  because you must prove yourselves worthy of your customers' trust.
+
+- **Churn Rate**: Also known as the rate of attrition or customer churn, the churn rate can be defined,
+  in this case, as the percentage of service subscribers who discontinue their subscriptions within a
+  given time period. We can distinguish two types of Churn:
+
+  - **Logo Churn**: It corresponds to the subscription cancellation rate.
+
+  - **Revenue Churn**: It corresponds to the monthly recurring revenue loss rate.
+
+  .. note::
+    Let's imagine an increase of 2$ on a service subscription.
+
+   - We loss three customers out of the initial 20 which gives us a **Logo Churn** of 15%.
+
+   - Therefore, the 56$ of MRR difference out of the initial 600$ gives us a **Revenue Churn** of 9,33%.
+
+   .. image:: media/reports_2.png
+    :align: center
+    :alt: Difference between logo churn and revenue churn in Odoo Subscriptions
+
+   As a reminder, though they seem to evolve in the same direction most of the time, it might not be
+   the case all time.
+
+- **Customer Lifetime Value (CLV)**: Very important measure which indicates how much revenue can be
+  expected for a customer during his/her entire contract. This approach emphasizes the importance of
+  customer retention, shifting our focus from a quarterly or yearly approach to a long-term vision.
+
+Check out the different kinds of reports you can access from the **Odoo Subscriptions** application.

+====================
+Close a subscription
+====================
+
+Losing a customer is always difficult, especially if you put a lot of effort into getting them to
+sign up for your products/services. However, many companies come up with dubious methods to reduce
+the probability of this happening.
+
+.. raw:: html
+
+   <div align="center" style="color:#AD5E99; font-size: 2rem ;margin: 20px 0"> <b>What is the right
+   way to go?</b> </div>
+
+1. If you adopt such methods, you are among companies that actively and indirectly spread the
+   phobia of subscriptions, who do not think about how negatively dissatisfied customers could impact
+   their business and, who frustrate the customers in a way or another. However, at some point, it is
+   understandable that you do not want your customers to be involved in your subscription status.
+
+2. If you do not adopt such methods, you are among companies that continue to evolve in a
+   long-term subscription business model, especially in an era of ultra-fast communications between
+   dissatisfied customers, and who retain their customers by making it easier for them to leave if
+   they want to. By giving them the opportunity to close their own subscriptions, your customers do
+   not feel trapped because they subscribed to your products/services.
+
+In summary, the **Odoo Subscriptions** application gives you the
+**possibility to choose what you want to apply**. Indeed, you can decide whether to give your customers the
+option to close their subscriptions whenever they want to or to restrict this possibility. It depends
+on you and we will show you how to do that in our amazing application.
+
+Configuration
+=============
+
+Go to :menuselection:`Subscriptions --> Configuration --> Subscription templates`. From there, you can
+create a new *Subscription template* or modify an existing one. When editing your template, underneath
+the Invoicing tab, you have the possibility to activate the option *Closable by customer*.
+Once enabled, this option gives your customers the right to close their own subscriptions.

+but, in some cases, manual subscription renewals are still the preferred option.
+
+With **Odoo Subscriptions**, you can have all your subscriptions in one application, suggest an

+Subscriptions are recurrent and go on indefinitely. As time passes by, our customers may want to
+modify them. We must then be able to adapt the prices or change the products’ quantities to
+accommodate their needs. Two situations can happen:
+
+1. **Loyal customers:** This kind of customers already trust you as a brand. Therefore, you are

+   Consequently, it is easier to sell them something additional than it would be to a
+   new customer.
+
+2. **New customers:** For this kind of customers, you have to come with something new, something
