Hi Mike,
A little over a year ago I wrote several articles that covered the 27 ways you can
mess up your inventory.
I used to have a saying after we completed our annual physical inventory: "Well, we are at 98% accuracy and it only gets worse from here!"
You are on the right track with trying to minimize the people who are doing the receipting. It doesn't necessarily mean you have to be the one doing it, but you want to limit the people who are.
Depending upon the computer system you are using, you have the opportunity to really look at your transactions and who is making the mistakes. For example, "PDA" with ADP systems will tell you the port number, the time, and the transaction that occurred. I can't begin to tell you how many times I found parts "double" posted.
I use to give the parts advisors access to the manual posting program to validate inventory counts if they found the counts to be wrong. This was a major mistake. The parts advisors did a visual count based on what they saw when reality was it could have been in the special order bin, or on will call, or the credit return bill. They never understand all the "variables" that could occur and how to do it.
In short, Mike, allow a chosen few to post, receipt, and adjust your inventory. I found over years of frustration and experience that the less people who made the computer adjustments and the less I tried to "purify" the inventory the more accurate my inventory stayed.
This may not make logical sense to you, especially if you have a big operation. Most parts managers will tell you that they will accept a degree of errors if the productivity and sales warrant it. After all, once you do a physical inventory, it is will correct the errors.
A good friend of mine, understanding the pitfalls of trying to maintain an accurate inventory, did a physical count quarterly.
I have offered you some experiences here with very little in the way of solution, but a lot will be determined on your environment, your computer, and the amount of control and education awareness you give to your employees.
