Retailers often use the term sell through to refer to the % sold vs. the % of inventory purchased.
With sized product a sell through of at least 80% is considered healthy. Anything above 80% could allude to missed opportunity since popular sizes or colors may have been nil and customers couldn’t buy it even if they wanted to.
With hard goods such as a best selling book a retailer may even plan for a sell through of 100%….but with apparel that is typically not the case.
If you’re a manufacturer inquire with your retailers about their sell through percentage on your product. You don’t want to find out about a 20% sell through by not having a re-order.
Check in with your stores from time to time….see if you can’t come up with some strategies together to make sure your product is going out the door and staying off the sale rack.
