 1.Costing Method 

For the same product, the purchase price may be different for different time of purchase, so how to calculate the unit cost of the product in stock?
The system is based on the Moving Average Costing.
Average Unit Cost=(Old Value + Purchase Value) / (Old Qty + Purchase Qty)

For example: 
  

As can be seen from the table above,

then the average cost of the balance on date 1 = (12000 + 3000) / (100 + 20) = 125

Unit costs need to be recalculated for each entry into the warehouse.

In the daily use of the system, negative inventory should be avoided as much as possible, because negative inventory not only leads to inaccurate inventory, but also leads to inaccurate costing.
