The unfortunate fact is that we all have old stock sitting in the shop. As a rule, they say that you should look into cull the bottom 20% of your stock.
You can look at the sales by GMROI, profit and numbers as I showed earlier. But you can also look at those products that are just sitting on the shelf. This is very easy to do and will take you only a second to do.
Go to register reports> Stock> Old Stock on hand.
Now pick a department and get a list of when this stock arrived and the quantity you have on hand. I am sure you will find some are very old; this will be costing you by just sitting there.
Now please decide what to do with this stock.
Note: You can also run this report by a supplier, which sometimes is handy as some suppliers will allow you to return old stock.
