When you order stock, consider being specific about when you want stock delivered. Group deliveries together, so that you may roster the business to make for the most efficient arrival of stock.
If you leave it to suppliers you might have stock arrive each day of the week when a more efficient solution could be to have two days set aside for processing this.
Depending on your competitive situation, you may want to leave deliveries coming as they are and only process the new stock on set days.
I appreciate the value of new product hitting the shop floor every day. However, managing the business for efficient use of labour is key given that labour is usually the second or third biggest operating cost for any retail business.
One option is that you arrive the stock, price it and have it ready for shop floor display on the day you nominate.
