Retailers spend a lot of time looking for ways to drive more traffic into their stores. More customers usually means more sales. But there is another opportunity sitting right in front of you: getting the customers who are already buying to buy just a little more.
One of the simplest ways to do that is to increase units per transaction.
Units per transaction, or UPT, tells you how many individual items the average customer purchases during a transaction. If your average customer is buying three items, getting that number to four can have a meaningful impact on your business.
And you don’t necessarily need more customers to make it happen.
Small Changes Can Add Up Quickly
Let’s say a store has 1,000 transactions in a month and the average customer purchases three items per transaction.
That means the store sells:
1,000 transactions × 3 units = 3,000 units
Now imagine the store can consistently get customers to purchase just one additional item per transaction.
The math changes dramatically:
1,000 transactions × 4 units = 4,000 units
That’s 1,000 additional units sold from exactly the same 1,000 transactions.
If the average selling price is $50, those additional units represent:
1,000 × $50 = $50,000 in additional sales
That’s a significant revenue opportunity without requiring the store to generate a single additional transaction.
Of course, selling more items per transaction isn’t always easy. The point is that small improvements in UPT can have an outsized impact when applied across a large number of transactions.
Start With the Customer, Not the KPI
The mistake is to look at UPT as simply a number that needs to go up.
Instead, ask why customers aren’t buying more.
Are associates suggesting complete outfits? Are customers finding the accessories that go with the primary item they’re buying? Are there logical add-on products positioned nearby? Does the assortment give customers a reason to keep shopping once they’ve found what brought them into the store?
For example, a customer buying a sport coat may also need a shirt, trousers and belt. A customer buying a dress may need shoes, jewelry or a handbag. The opportunity isn’t to push unnecessary merchandise. It’s to make it easier for the customer to find the things that complete the purchase.
That’s where merchandising and selling work together.
Look at Your Own Numbers
The first step is to understand your current UPT and how it varies.
Look at it by department, category, store, salesperson, and even customer type where your data allows. You may find that some areas of the business are already producing much higher units per transaction than others.
If one category routinely generates three units per transaction while another generates five, ask what is different. Is it the product? The price point? The way it is merchandised? The way associates sell it?
Then look at what happens if you improve the number incrementally.
You don’t have to double your UPT to make a difference. Adding even one additional item to the average transaction can produce substantial revenue when multiplied across hundreds or thousands of transactions.
And if you can add two, the opportunity becomes even bigger.
Before you spend more money trying to drive traffic, take a look at what is happening inside the transactions you already have. There may be more revenue there than you think.
