Inventory valuation methods are used to calculate the cost of goods sold and cost of ending inventory.
Following inventory valuation methods are supported by RepairDesk.
Weighted Average Method First-In, First-Out Method Last-In, First-Out Method
Weighted Average Method (W.A)
Under average cost method, weighted average cost per unit is calculated for the entire inventory on hand which is used to record cost of goods sold. Weighted average cost per unit is calculated as follows:
Weighted Average Cost per Unit= Total cost of goods sold / Total unit in inventory
First-In, First-Out Method (FIFO)
According to FIFO, it is assumed that items from the inventory are sold in the order in which they are purchased or produced. This means that cost of older inventory is charged to cost of goods sold first and the ending inventory consists of those goods which are purchased or produced later. This is the most widely used method for inventory valuation. FIFO method is closer to actual physical flow of goods because companies normally sell goods in order in which they are purchased or produced
Last-In, First-Out Method (LIFO)
This method of inventory valuation is exactly opposite to first-in-first-out method. Here it is assumed that newer inventory is sold first and older remains in inventory. When prices of goods increase, cost of goods sold in LIFO method is relatively higher and ending inventory balance is relatively lower. This is because the cost goods sold mostly consists of newer higher priced goods and ending inventory cost consists of older low priced items.
Note: for serialized inventory – the cost of each serial will be used to calculate the COGS.

Reports
Value of inventory can be seen through inventory summary Report
Inventory Summary Report
Valuation method field is hidden when Serialized Inventory toggle is enabled.
CASE 1: Weighted Average
3. When new adjustment is made against a current item with different cost, weighted average is changed.
New adjustment is added with price cost price=30
Admin history will be updated accordingly.
CASE 2: LIFO
3. At the time of sales transaction system will sell out the item as per valuation method. As item with cost 30 was added last. so while sales transaction it was sold first.
It can be verified by admin history and the last GRN Created.
4. One more item is added through GRN with cost =80
5. when sales transaction is carried out system will sell item with cost 80 as it was added at last in the system.
It can be verified by Admin history and last GRN Created.
4. At the time of sales transaction system will sell out the item as per valuation method. As item with cost 30 was added first so while sales transaction it was sold first.
It can be verified through admin history and GRN:
GRN:
5. One more item quantity is added through GRN with cost =80
6. When sales transaction is carried out system will sell item with cost= 50 as it was added first in the system as compared to other item quantity.
In case of serialized inventory, selection of valuation method disappears.
In case of serialized inventory, every serial may have different cost price and different retail price.
Profit is calculated as per serial cost where each serial has its own cost and profit is calculated accordingly.
1. Created new inventory item
2. Added 5 new quantity through GRN
User can either generate serial at the time of receiving GRN. Price is zero, a user want to have different cost price for each serial.
3. Clicking on create serial will open a popup. Press save and serials will be created.
4. When serials are created against any newly added item, selection of valuation method is disabled for that item.
5. User can give different cost and retail price to each serial.
6. At the time of making transaction system allow us to select which serial we want to sell.
When we select a specific serial cost associated with it will be used for profit calculation.
