What is GRN Posting and Why you Should Do It?

Understanding GRN Posting


As you know, the cost price of various goods and services is variable and can change periodically. For example, 20 pieces of a particular items can cost 100 per piece, and 40 pieces of the same item (when you purchase it next time) cost 120 per piece. This makes it important to calculate an average cost that can reflect realistic profit margins.

Depending on the nature of the business, such cost changes can be occasional or frequent. Cost price management is important for three critical reasons:

  • To reflect accurate profitability.
  • To give a correct estimate of your inventory value. 

GRN posting does three things:


  • Creates average cost price
  • Locks all purchase transactions till the GRN posting date thus no changes can be made to such transactions.
  • Once the GRN posting is done, cost will  update in the system and the new weighted average cost will show on the Product Definition, and profit margins will be reflected accordingly in all reports.
