It's 3:40 on a Sunday afternoon in a shoe shop. A man has just bought a pair of running shoes for $180.
He tried on three pairs. He jogged a little loop by the mirror, the way everyone does and nobody admits to, then tried a quick moonwalk when he thought nobody was looking. He asked if they'd be any good on wet footpaths. Then he paid, said thanks and left.
Nobody mentioned socks. Nobody asked if he had a race coming up, or whether his old pair gave him blisters. The sale stayed at $180. The person who served him was keen to get back to stacking shelves.
That sale went into the shop's ATV and pulled it down a little. Nobody noticed. Do that every Sunday afternoon for a year and you've got one of the quietest leaks in retail.
What is average transaction value?
Average transaction value, or ATV, is how much a customer spends each time they buy. To calculate average transaction value, divide your total sales by the number of transactions over the same period.
If the shoe shop takes $28,500 in a week across 300 transactions, its average transaction value is $95.
It's the one part of your sales you can lift without a single extra person walking through the door. The customer is already at the counter with their card out. All that changes is what goes in the bag.
How do you increase average transaction value?
Mostly by doing the obvious thing, on purpose, every time. Six things that move it:
- Know the natural add-on. Shoes and socks. A dress and the belt it was styled with. Paint and a roller. Every category has one. Every staff member should be able to name it without thinking.
- Ask one more question. "Is this for anything in particular?" turns a $180 sale into a chat about a half marathon. And a half marathon needs socks, gels and probably insoles.
- Bundle, don't discount. A discount teaches people to wait for the sale. Socks sitting next to the shoes at the counter just remind them.
- Staff the busy hours properly. An add-on takes a spare thirty seconds. On a stretched shift, nobody has them.
- Watch items per sale too. Units per transaction is ATV's quieter sibling. If it sits at one, nobody's suggesting a second thing.
- Track it by hour, not by month. A monthly ATV is an average of your best and worst afternoons, so it tells you very little about either.
Now the sums. These numbers are illustrative, but you get the point.
Say one in four of those 300 weekly customers adds an $18 pair of socks. That's 75 extra pairs and $1,350 a week. ATV goes from $95 to $99.50. Over a year, that's about $70,000 from one shop, from people who were buying shoes anyway.
Why does ATV drop when the shop is busy?
Your monthly report won't show you this.
When the shop is busy, staff switch from selling to processing. Scan, pay, next. Everyone gets served, but nobody gets sold to.
So the hours with the most customers are often the hours with the lowest spend per customer. On a Sunday afternoon the shoe shop has its biggest crowd and two people on the floor. ATV slides to $80. On a quiet Tuesday morning it sits at $105. The month averages out to $95 and everyone nods.
Quiet hours come with a catch, though. A quiet shop gives your staff time to talk to customers. Great staff use it. They ask the extra question, mention the socks, fetch the other size. Other staff use it for a POS party: two people at the counter catching up on the weekend while a customer wanders round on their own. Same quiet hour, very different ATV.
So you need two things: enough people on the floor when it's busy and a team that sells when it's quiet. To see which one you're missing, put your sales next to your footfall, hour by hour. The Sunday dip stops being a hunch and turns into something you can roster for. We've written about how your staff-to-customer ratio costs you revenue. ATV is one of the first places it shows up.
ATV, conversion or footfall: which should you fix first?
Your sales are three numbers multiplied together. Footfall (foot traffic, if you're reading this in the US) is how many people came in. Conversion is the share of them who bought: transactions divided by footfall, multiplied by 100. ATV is how much each buyer spent.
Footfall is the expensive one to move. It usually means more advertising, a better site or a lucky month. Conversion and ATV are cheaper, because they work on people you've already paid to get inside.
Between those two, look at the hour. If people come in and leave without buying, start with conversion. If they buy but buy small, start with ATV. If both drop at the same time every week, it's probably not your customers. It's how many people you had on the floor and what they were doing.
Back to the man with the running shoes
He'll need socks. He'll buy them somewhere, probably online, probably tonight. The shop that sold him $180 of shoes had the best shot at selling him the rest. It let him moonwalk straight out the door, because the person who served him had shelves to stack.
If you want your team asking that one more question every time, retail coaching is where it starts. Hourly data shows you which afternoons need it most.
Your sales report tells you the average. Bellwether shows you how to lift ATV at 3:40 on a Sunday.
