Here is a snip from the article, see link at bottom for the whole thing…

As small retailers, it’s even more important that we have the inventory in stock.  It’s another one of those customer service elements that can separate us from the big guys.

A bit ago, I wrote about the need for newness.  And that’s true.  You need to offer new products for your customers.  But if you’re going to discontinue a line, make sure it’s for the right reasons as follows:
1.    The manufacturer is discontinuing the line
2.    The line isn’t selling
3.    The line duplicates another line you’re carrying that’s selling better

Secondly, make sure you have the products in the store.  Bulk up on your best sellers so you never run out.  Do you know how to access your inventory position on your computer system?  Do you know how to look at product turns or weeks of demand to determine how much inventory you should be carrying?  If not, let me know, and I’ll call in one of my merchandising experts to give the basics of managing inventory.

Get the right products in your store and ensure they are always there.  After all, if you don’t have anything to sell, then you don’t have a business.
