As many as 81% of shoppers report suffering from an unavailable product at a brick-and-mortar store in the past 12 months. This results in 55% of disappointed shoppers becoming lost sales,” according to a GT Nexus study.

The survey that was conducted by YouGov, found that 65% of online shoppers have similarly been disappointed by out-of-stocks in the past 12 months. The consequences can be costly for retailers, as 57% of shoppers pointed fingers at the retailer or manufacturer when a product was unavailable.

“This study shines a spotlight on a global inventory crisis that is frustrating consumers, and impacting the bottom line of retailers,” said Kurt Cavano, founder and chief strategy officer at GT Nexus. “In today’s competitive environment it’s hard enough to get the attention of consumers, but winning them and then losing them due to out-of-stock is very damaging.
