Running out of stock is not just a back-end inventory issue anymore. For many shoppers, it is enough to push them toward a competitor. As consumers grow used to fast shipping, endless product choice, and real-time availability, a missing item can quickly become a loyalty problem.
In a new study, DOSS surveyed 1,000 U.S. adults and analyzed 8,679 Reddit posts across 18 major brands and product subreddits to see how stockouts affect consumer behavior and where shoppers complain most.
The findings show that out-of-stock products are costing brands more than a single sale.
Key Takeaways
- 82% of consumers would try a competitor if their go-to product is frequently out of stock.
- 74% of consumers encountered an out-of-stock product they regularly buy in the past 12 months.
- 62% of consumers have switched to a competing brand because of a stockout.
- 53% of shoppers hit stockouts in food and grocery
- 25% of consumers say stockouts damage their trust in a brand.
- Over 1 in 13 fashion and apparel posts analyzed (7.9%) on Reddit mention stockout language, the highest rate of any category.
- Sephora ranks highest among retailers in the dataset: 12.8% of Reddit posts analyzed mention stockout language.
The study also breaks down where stockout frustration is most visible online, including complaint rates across fashion, beauty, electronics, grocery, and mass retail. Brand-level Reddit analysis includes Sephora, Alo Yoga, Lululemon, Trader Joe’s, Ulta, Best Buy, Target, Costco, Amazon, Walmart, and more.

Question: The study suggests stockouts are becoming a loyalty issue rather than just an inventory problem. What changes do retailers and brands need to make to prevent a temporary out-of-stock situation from turning into a permanent customer loss?
Answer: Stockouts are no longer seen as a one-off or short-term problem with availability. The shopper data now indicates that stockouts increase consideration of alternative products and may ultimately lead to abandonment of the original brand. If 82% of consumers indicate they would seek out an alternative to their primary brand due to frequent unavailability of their preferred item, it’s unreasonable for retailers to expect their customers to continue waiting for what they need.
Therefore, retailers should utilize stronger systems for real-time inventory monitoring, which in turn enables brands to communicate more clearly about when products will again be available (and when). In practice, a large share of what gets recorded as a stockout is actually a visibility program – the inventory exists somewhere in the network, but procurement, warehousing, 3PLs, and sales channels are working off of different numbers, and as a consequence, are missing the sale.
Q: With 82% of consumers saying they would try a competitor when a preferred product is frequently unavailable, which retail sectors are most vulnerable to losing market share because of stockouts, and why?
A: Fashion, electronics, and beauty were among the most vulnerable categories, not because shoppers are indifferent, but because they combine high emotional specificity with low switching costs and abundant substitutes. As our Reddit analysis confirmed, fashion drove the highest share of stock-out complaints at 7.9%, followed by beauty/personal care (7.5%) and electronics (7.4%). These are also the categories with the most operational complexity — high SKU counts, fast trend cycles, and frequent new releases are where fragmented systems break down first.
Q: Your Reddit analysis found particularly high levels of stockout discussion in fashion and beauty. What factors make these categories especially prone to consumer frustration when products are unavailable?
A: Stockouts have an even greater impact on fashion and beauty products than many other categories because so many people buy these items based on trends, routines or what makes them unique. When a particular skin care product, colour, size or limited release item is out of stock; consumers do not view this as simply being inconvenienced. Consumers perceive that something about their daily routine and/or identity has been impacted.
This explains why Sephora was at the top of our list for retailers by stockout complaint rates (at 12.8%) when we analyzed social media posts containing stockout-related words. Additionally, these categories run on limited releases, shade and size variants, and short replenishment windows – the exact conditions where a system that can’t track inventory in real-time across channels will show ‘available’ on something that’s already gone.
Q: The data shows that 25% of consumers say stockouts damage their trust in a brand. What distinguishes brands that successfully retain customer loyalty during inventory shortages from those that do not?
A: The brands that retain trust treat inventory accuracy as a brand-protection issue and a driver of customer satisfaction and topline growth, not a back-office one. When procurement, production, fulfillment, and sales channels run on one real-time system, the “sorry, it’s actually out” moment never reaches the customer.
In the event of a stockout, the biggest risk is being silent. When a customer has checked on the availability of a product multiple times and receives no information regarding the status of the product from the brand, the customer’s anger turns to distrust very rapidly.
Q: Looking ahead, how should retailers balance inventory efficiency and cost management with consumer expectations for constant product availability, especially in an era of fast shipping and real-time inventory visibility?
A: The retailers that get this right aren’t choosing between inventory efficiency and customer expectations for availability. They’re closing the gap between the two. The problem is that most operations teams are still making replenishment decisions on data that’s hours or days old, spread across disconnected systems. When your procurement, inventory, and order data share a single and real-time view, you stop buffering against uncertainty with excess stock and start making precise, location-specific decisions. You carry less, but you have fewer stockouts, because the inputs are more accurate.
