+
+If your company runs a perpetual inventory system, you may need to perform
+inventory revaluation. A revaluation updates both the inventory
+account balance, and the stock value of products.
+
+This module takes three different methods of stock revaluation
+
+- Stock-Move-Specific Valuation (FIFO costing)
+- Simple Price Change (standard/average costing)
+- Inventory-Total-Value Price Change (standard/average costing)
+
+
+Stock-Move-Specific Valuation
+=============================
+
+Stock-Move-Specific valuation applies if the product is configured for FIFO
+costing. In this case, the user selects specific stock moves for which to
+change value. A journal entry is created for each stock move on which the
+value is changed.
+
+
+Simple Price Change
+===================
+
+A simple price change updates the standard/average cost of the product,
+regardless of the available stock. The user specifies a new per-unit price,
+and posts the change. A journal entry is created for all stock moves having
+positive remaining stock value. The amount of the posted entry is the
+difference between the new and old price, multiplied by the quantity available.
+
+
+Inventory-Total-Value Price Change
+==================================
+
+This is a price change, based on total available stock value. It updates the
+standard/average cost of the product, based on available stock. The user
+specifies a new total value for available stock. The standard/average price
+of the product is updated to the new total value divided by the available
+quantity. A journal entry is created for all stock moves having positive
+remaining stock value. The amount of the posted entry is the difference
+between the new and old total value.

+Configuration
+=============
+
+* Users wanting to access to the Inventory Revaluation menu should be
+  members of the group "Manage Inventory Valuation and Costing Methods".
+
+* The Revaluation can automatically select contra-accounts to the Stock
+  Valuation Account.  To configure this, define a Valuation Increase Account
+  and a Valuation Decrease Account for each product category. Do that here:
+  *Inventory / Configuration / Products / Product Categories*
+
+Usage
+=====
+
+- Go to *Inventory / Inventory Control / Inventory Revaluation* to create a
+  new Inventory Revaluation.
+- For products set with average/standard price, and automated valuation, go
+  to the Product form and use the "Update Cost" link to change the standard
+  price.
+- In order to post the inventory revaluation for multiple items at once,
+  select the records in the tree view and go to
+  *Action / Post Inventory Revaluations*.
+- To set default valuation increase/decrease accounts by product category, go
+  to  *Inventory / Configuration / Product Categories*
+
+Known issues / Roadmap
+======================
+
+- Known Issue: We can't revalue individual lots/serials if there are multiple
+  on the same stock move
+
+  - Version 11 moved the cost from stock.quant to stock.move.  That
+    means there is no longer an individual cost assigned to specific
+    lots/serials.
+  - As a work around, you can internally transfer the lot/serial you want to
+    revalue.  This will separate it from the other lots/serials on the
+    original inbound stock move.
+
+- Known Issue: Actual resulting stock value may differ slightly from that
+  specified by the user.  This can result when the Product Price
+  decimal precision is low, and there is a large quantity of product to
+  revaluate. For example:
+
+  - If we have 147 units on hand, and the precision for Product Price is 2
+    digits
+  - When we specify a new value of 750, the actual value applied is 749.70
+  - At full precision, 750 / 147 = 5.102041, but the product cost gets
+    rounded to 5.10, and 5.10 * 147 = 749.70
+  - As a work around, you can change the decimal precision setting for Product
+    Price to have a greater number of digits
+
