+This module allows to generate cut-off entries automatically when posting former
+entries.
+
+This module is based on `account_invoice_start_end_dates`
+which allows to define start end end dates on invoice line (`account.move.line`).
+
+
+Following assumption have been made before developing this module::
+
+  - New method to compute cut-off amounts can be add by business modules
+
+
+.. note::
+
+    This module has few design choices that require explanation::
+
+      - we don't want rely on user nor async task at the end of
+        each month (period)
+      - link entries to understand the history without merging amounts
+        in order to be able to keep details on deferred account
+        move line (analytics, partners, accounts and so on)
+

+
+Configuration
+=============
+
+Deferred journal(s)
+~~~~~~~~~~~~~~~~~~~
+
+In accounting configuration you should set
+Deferred Revenue and Expense journal to be used
+on generated entries.
+
+.. note::
+
+    Journal will be used according the kind of
+    journal used by the former entry: `sale` or `purchase`
+
+
+Deferred account(s)
+~~~~~~~~~~~~~~~~~~~
+
+On each Revenue/Expense account you can set the deferred
+Revenue/Expense account.
+
+Only invoice lines linked to account with a deferred account set
+will generate deferred Revenue/Expense.
+
+
+Cut-off Method
+~~~~~~~~~~~~~~
+
+In the first version of this module, two cut-off computation methods are
+supported and can be configured using the ``account_move_cutoff.default_cutoff_method``
+key. The currently possible values are ``monthly_prorata_temporis`` or ``equal``.
+
+Before defining these values, let's provide some context by using an example to
+illustrate the definitions. Consider a sales invoice that is posted on January
+16th for a service that spans from the 8th of January to the 15th of March. So, there are
+24 days in January, 1 full month in February, and 15 days in March. The product
+is sold for 1000 for a month, so the invoice line amount (excluding VAT) is
+calculated as follows::
+
+    24/31 * 1000 + 1000 + 15/31 * 1000 = 2258.06
+
+* **monthly_prorata_temporis** (the default if not set): This method splits amounts
+  over the rate of the month the product has been used. The results would be as
+  follows:
+
+  - January: **774.19** (`2258.06 - 1000 - 483.87`) (Subtraction is used here to avoid
+    rounding discrepancies.)
+  - February: **1000.00** (`1 * 2258.06 / (24/31 + 1 + 15/31)`)
+  - March: **483.87** (`15/31 * 2258.06 / (24/31 + 1 + 15/31)`)
+
+* **equal**: With this method, the same amount is split over the months of service.
+
+  - January: **752.68** (`2258.06 - 752.69 - 752.69`)
+  - February: **752.69** (2258.06 / 3)
+  - March: **752.69** (2258.06 / 3)
+
+Please note that this information is subject to change based on updates to the
+module. Always refer to the latest documentation for accurate details.
+
+Usage
+=====
+
+To handle deferred accounting, follow these steps:
+
+1. Set the start and end date, where the end date is at least set to
+   the month after the current entry posted date.
+
+2. Ensure that the account (the `account.account` configuration)
+   in use is linked to a deferred account.
+
+3. Post the entry.
+
+4. After posting, check deferred entries have been generated, posted, and
+   reconciled if needed.
+
+.. note::
+
+   This module only defers amounts in periods subsequent to the accounting period
+   date. For example, if an invoice is posted on March 2nd for a service from
+   January 1st to March 31st at 1000€ per month, the deferred amount will be
+   only 1000€ for March, leaving 2000€ in February. We never add accounting items
+   in periods previous to the current entry date.
+
+Known issues / Roadmap
+======================
+
+- Make the is_deferrable_line a storable field to allow end user to not
+  defer a given line while posting entry. (but should raise if
+  it's not possible to force the value to true)
+- allow to change/configure cut-off frequency (weekly/monthly/...)
+  today only monthly is implemented
+- allow to configure cut-off computation method in different
+  place (product / invoice lines /...)
