You can't manage what you don't measure. Here are two numbers you should be measuring this holiday season.
Traffic Count: How many sales do you have per day (Monday, Tuesday, Wednesday...)? Per day part (morning, afternoon, evening)?
Knowing this can help you schedule your staff to better meet the peaks and valleys of your daily & weekly sales. It also helps you measure the success of your marketing and your customer service. If traffic counts are up, you're doing something right. If they are down, you better figure out why (and it isn't just the economy).
Average Ticket: How much is the average transaction or sale? Which employees have higher or lower averages (if applicable)?
This number helps you measure the effectiveness of your sales staff and promotions. It also helps you understand your merchandise better. Are you getting the add-on sales? If not it could be that you don't have the right products to complete a customer's purchase. If you sell dolls, you better sell doll stands. If you sell electronics, you better sell batteries.
Measure these two numbers. They have a lot to say about your success.
