The biggest culprit in shrink is in the store — but it’s probably not a criminal

Understaffing a store isn’t headline-worthy. Yet, at many retailers, such inefficiencies forfeit more inventory than the smash-and-grab robberies that go viral or make the news.

Organized retail crime continues to hold the attention of policymakers and retail industry groups. But some loss prevention experts say the impact of external theft on inventory loss or shrink is overstated, while the causes of nearly two-thirds of shrink are going largely unappreciated and, therefore, unaddressed.

Inventory loss is out of the spotlight to a great extent, in part because many, if not most, retailers that had been complaining about shrink levels have reported improvements. After about 30 years, the National Retail Federation last year said it would no longer report on shrink trends in the industry. 

Still, laxity related to labor, pricing, promotions, stock management and other store operations lead to shrink and cost retailers billions, according to a recent study from Coresight Research. The percentage of gross sales lost to in-store inefficiencies stands at 5.5% on average, up from 4.5% last year. Overcoming those inefficiencies could save U.S. retailers in the home improvement, drugstore, grocery, mass merchant and warehouse club sectors as much as $162.7 billion, up 27% since last year, per Coresight.

Tackling this requires a hard look at store operations and, for most retailers, a more holistic approach to loss prevention, experts say.

“When I started, I was a bad-guy catcher. I wanted to catch bad guys, I was good at catching bad guys. I loved the adrenaline, I loved the cat and mouse. That’s all I wanted to do,” said Johnny Custer, senior director of retail risk solutions at ThinkLP. “I’ve evolved from that. There are some very progressive retailers where the relationship between operations and LP is seamless, where loss prevention is a specialized extension of the operations team. That’s ultimately where we all need to be. But they are few and far between.”

Margin protection

That evolution requires retailers to view their loss prevention teams as not just crime fighters but as protectors of profits and margin more broadly.

“Loss prevention is perceived as a cost center. A necessary cost center, a part of doing business,” Custer said by video conference. “My goal is to change that perspective so that people understand that we’re not a cost center, we can actually be a profit driver.”

Errors in merchandising, pricing and other functions add up quickly, according to Brad Bogolea, CEO and co-founder at Simbe Robotics, which sponsored Coresight’s research.

More than 80% of the 394 retail business decision-makers that Coresight surveyed said they’re losing at least 5% of their operating margin to in-store inefficiencies; last year just 70% reported that. This year, mistakes related to promotions have been the biggest challenge, with nearly 40% ranking it in their top five, while nearly that many cited pricing errors. Losses from out-of-stocks also stood out, with 57% reporting the issue.

“Even small lapses — a product on the wrong shelf, an incorrect label — can cascade into major losses,” Bogolea said. “These issues erode margins and create friction for shoppers. In contrast, retailers that solve for visibility are seeing a step-change in performance across supply chain, e-commerce fulfillment and store operations.”

Unpacking where margins are being squeezed by operational failures requires data, something Custer learned when he was working in loss prevention for someone who was a data analyst.

“He expanded my mind and asked me to look into point-of-sale. And then, not only point-of-sale, but center of store, all of the sales-floor data, then the back of the store — all the inbound, outbound flow data,” he said. “To look for similar patterns of behavior that occur within each, because loss can happen anywhere in the building. I did it reluctantly, but I became a believer the moment the financial results came out.”

Tech to the rescue

Getting that data — and the visibility into store operations that it provides — is enabled by technologies that find mistakes, flag needs and detect patterns.
