Try this method: Since 80% of your most active parts (run a piece sales ranking report with the past 12 months demand) then counting 200-300 of the most active numbers will spot more descrepancies than trying to count the whole inventory several times a year.
Go to the report generator and order a list that has the following criteria:
1. all parts with 2 or more on-hand
2. all parts with last 12 months sales greater than 9 (10 or more)
3. sort the list by bin location
count these monthly and you will have a very good and supportable program; this is the verification of the on-hand count integrity. You also have to run an accounting reconcilliation; one of the best procedures was started by Sandy Jerome; you can download the forms and the method from
www.partsconsulting.com; go to the downloads and download the reconciliation form and the how to do the reconciliation. It is not copyrighted and open for everyone; your download and/or inquiry is never stored for marketing purposes.
