-Visibility days
-===============
-
-*Visibility days* enable the ability to determine if additional quantities should be added to the
-planned replenishment. Odoo checks if forecasted stock on the forecasted date will drop below the
-minimum in the reordering rule. **Only if** it is time to reorder, visibility days check additional
-future demand by the specified number of days.
-
-.. note::
-   Visibility days extend the standard just-in-time replenishment logic by looking beyond the
-   immediate forecasted date. To fully understand how Odoo determines when replenishment is
-   triggered, refer to the :doc:`Just-in-time logic <just_in_time>`
-
-This feature helps consolidate orders by grouping immediate and near-future needs, reducing
-transport costs and enabling supplier discounts for larger orders.
-
-To set visibility days to incorporate orders for a specified number of days in the future, navigate
-to :menuselection:`Inventory app --> Operations --> Replenishment`, or by clicking the *Reordering
-Rules* smart button from the product form.
-
-Next, enable the :guilabel:`Visibility Days` field by clicking the |adjust| to the far right and
-choosing the feature from the drop-down menu. Then, enter the desired visibility days.
-
-.. important::
-   The forecasted date is never pushed forward or extended; Odoo only checks the extra visibility
-   days if the stock falls below the minimum threshold on the forecasted date.
-
-Example where visibility days is triggered
-------------------------------------------
-
-A product shipped from Asia has a combined vendor lead time of 30 days and a shipping cost of $100
-(including :doc:`landed costs <../../inventory_valuation/landed_costs>` and
-tariffs).
-
-- November 4: Current date. The forecasted date is December 4 (30 days later).
-- |SO| 1: Requires the product by Dec 4. Odoo places the order today, costing $100.
-- |SO| 2: Requires the product by Dec 19. Normally, Odoo would order on Nov 19, costing an
-  additional $100.
-- |SO| 3: Requires the product by Dec 25. Normally, Odoo would order on Nov 25, costing another
-  $100.
-
-Ordering separately for these sales orders totals $300 in shipping costs.
-
-.. image:: reordering_rules/forecasted-date.png
-   :alt: Show forecasted date visualization.
-
-Setting :guilabel:`Visibility Days` to `20.0` allows Odoo to "look ahead" 20 days from December 4
-(|SO| 1's forecasted date) to December 24.
-
-- It groups |SO| 2's order with |SO| 1, reducing shipping costs by consolidating orders.
-- |SO| 3, which is due on Dec 25, is one day late and is not grouped with the other two orders.
-
-Counterexample where visibility days is not triggered
------------------------------------------------------
-
-Considering the example above, if |SO| 1 does not exist, then:
-
-- **November 4**: Current date. The forecasted date is December 4 (30 days later).
-- **November 5**: The forecasted date shifts to December 5.
-- |SO| 2: Requires the product by December 19. Odoo will only trigger the order on November 19,
-  meaning the user will not see a replenishment notification until then.
-
-This shows that visibility days complement just-in-time logic by optimizing it to balance
-replenishment costs more effectively.
