Tl:dr - Retail shrink costs merchants over $112 billion a year, and most of it isn't coming from where you think. Beyond shoplifting, there's employee theft, phantom inventory your system never flags, BORIS return fraud running 48% higher than other channels, and a normalization trap that makes consistent losses feel like stability. This blog breaks down every type of shrink, the new omnichannel vectors your old playbook missed, and a practical framework to fix the right things first.
Want to see a magic trick?
I'll make your inventory disappear.
No smoke or mirrors... just a slow Tuesday, a mislabeled shipment, a cashier who likes her coworker a little too much, and a return that arrived in a box full of rocks. And abracadabra! Your $2,000 are gone!
And your system? Don’t worry, it still says everything's fine.
In the words of the grand wizard of ecommerce, that’s retail shrink - the loss of inventory between the point of manufacturing or purchase and the point of sale, resulting in less actual stock on hand than listed in records.
For instance, you ordered 500 units. Your system says 500 units. You count the shelf and find 463 units. Where did those 37 missing units go? That's the shrink (AKA inventory shrinkage) and they represent revenue that walked out the door without saying goodbye.
And it's not the dramatic heist your security cameras are looking for. Most of the time, it never even looks like a crime, I mean take a look at it yourself:
“So I recently put in my resignation and I worked in the highest shrink store in walmart history. It set the record last year and again this year with a 5.2%. The shrink isn't from the customers its from associates. I remember 1 month here recently the store manager had ordered full sheet cakes for her friends and not pay for them And donuts every single morning. This alone was adding nearly $700 to bakery shrink each month.”
The accepted shrinkage in retail is around 1.4% to 2%, but that number is about 3x the average.
However it’s hard to deny this Walmart must be a fun place to work at.
Now, if you've been in retail for a few years, you already know the basics. You've heard "lock up your high-value items," "do inventory audits," "watch for sweethearting." Good advice. Also the advice every one of your competitors got. The blogs that rank on Google for "retail shrink" will tell you that theft is bad and cameras help. Profound stuff.
This isn't that blog.
But, let’s get into it the basic stuff first.
Want to calculate Retail Shrink at home? Here’s the formula: Value of Lost Inventory ÷ Total Inventory Value = Shrink Rate
Shrink doesn't come from one place. It comes from five, and most merchants are only watching one of them. I know it sounds confusing, but you’ll have better clarity after reading this:
1. External theft (shoplifting + Organized Retail Crime): The most visible type. Shoplifters, opportunists, and increasingly, coordinated ORC groups who target high-value merchandise across multiple locations. External theft accounts for roughly 36% of total shrink.
2. Internal/Employee theft This one stings more because it's personal. Employees account for about 29% of retail shrink (probably the number is a lot more now). It shows up as sweethearting (ringing up friends at fake discounts), cash skimming, and manual inventory adjustments that lead to stealing, and more.
3. Administrative and process errors Nobody talks about this one loudly enough. These include miscounted receiving, wrong SKU entries, pricing errors, inaccurate cycle counts, botched transfers between locations, you know the like.
4. Return fraud and abuse Wardrobing, bracketing, empty-box returns, receipt fraud, stolen-tender returns, etc. cost retailers around $103 billion to fraudulent and abusive returns in 2024 - roughly 15% of all returns processed.
5. Vendor fraud and errors Short-shipped orders, substituted products, double-invoiced shipments. Shrink that happens before your inventory even hits the floor. This is often the least monitored category and therefore one of the easiest to exploit.
Honestly, you don’t have to be a magician to find out.
Theft (internal and external) is the biggest single driver, accounting for roughly 64% of shrink in 2024, as made clear by this Redditor:
“Our SM told us that our shrinkage is crazy high and her DM is really getting on her about it. I asked what's getting stolen a lot, and it's mostly laundry stuff and baby stuff. I was scrolling FB marketplace cause I know a lot of theft like that is sold through there. I found one lady selling a ton of laundry stuff on marketplace. I clicked her listings, and like almost everything she sells we also sell at DG. So, the kicker is, I'm friends with a coworker on FB and when I scrolled through her bio, come to find out that this FB seller is first cousins with my coworker..lol. so anyway, I'm guessing when she works alone, she calls her cousin up and they load up a car full of shit to sell on FB.”
So, yes, it's fed by weak controls, undertrained staff, blind spots in store layout, and policies so lenient they invite abuse.
Process errors, the next best reason, are fed by outdated systems, poor receiving workflows, and inventory audits that happen once a year when they should happen monthly.
Lastly, it could be return fraud, fed by generous policies that were designed to build customer loyalty but ended up building a pipeline for organized fraud rings.
Wait... Is this the same as Shrinkflation?
No. Shrinkflation is your supplier's move, i.e., when manufacturers reduce the size or quantity of a product while keeping the price the same. Retail shrink is your problem, an inventory loss that hits your bottom line without a sale.
So, you've expanded beyond a single channel, selling both online and in-store. Congratulations. You've also unlocked a whole new set of shrink vectors that the old playbook doesn't cover:
A customer buys online at a promotional price, returns it in-store where staff don't have visibility into the original transaction, and receives store credit at full retail value. Rinse and repeat.
That’s BORIS fraud.
And in 2024, it, combined with Buy Online Return Online (BORO), accounted for over 52% of all returns in 2024.
Buy Online, Pick Up In Store sounds frictionless. And it is... especially for frauds and tricksters. They place an order, the system confirms inventory it doesn't actually have (hello, phantom inventory), staff scrambles to fill an order that can't be filled, and the cancellation creates a refund loop.
To understand this fancy term, let’s take an example. Suppose a customer buys a product online at a sale price, walks into a store, and returns it for full-price store credit. The online and in-store systems don't talk to each other, so no one catches it. That’s cross-channel inventory arbitrage and it is a documented pattern that grows proportionally with every channel you add.
Let’s ask a question nobody asks after "how do we stop shrink?": how much are we allowed to spend doing it?
Locking your entire high-value section behind glass reduces external theft. It also reduces sales because legitimate customers don't want to flag down a staff member to buy deodorant. Self-checkout shrink rates run 3.5% versus 0.2% at staffed lanes. That’s a 17x difference. But 96% of retailers are already using it or plan to. Eliminating it isn't viable.
The real question is ROI: if a prevention measure costs you $X in friction and conversion loss, and saves you $Y in shrink, is the math positive? Most merchants never run this calculation. They install the camera first and ask questions later.
Our advice: don’t be that merchant.
Stop trying to fix everything at once. Shrink has different causes in different stores, categories, and channels.
Here's a decision framework:
Every merchant has a loss prevention plan. Almost nobody has a loss diagnosis - a backward-looking audit of where the money actually went last year.
So, before you write your next prevention strategy, do a shrink autopsy on the last 12 months:
Patterns tell you where to look. The shrink autopsy turns a reactive problem into a solvable one. You stop guessing and start prioritizing.
Retail shrink isn't going away. But you can moderate it by making the shrink visible... by measuring it accurately, auditing it regularly, and treating it as a systems problem instead of a security problem.
If you want help building those systems from smarter return policies to real-time inventory protection, Surebright is built for exactly this.
The setup takes ten minutes and integrates natively with Shopify, WooCommerce, BigCommerce, Lightspeed, Magento, and more - matching your store's UI without looking like an add-on. And the average warranty conversion rate across their merchant base sits at 20.2%, meaning one in five customers who see the offer take it.
So, if you're a merchant who's spent years managing shrink from the loss side, SureBright is the other side of that equation: converting product risk into product revenue,
