Office supplies from Costco and Office Depot have long been staples of office-supply stores and online shopping sites.
But a new study by consultancy Accenture, published on Tuesday, has found that some brands are now underperforming compared to others.
The study, entitled “Office Supplies 2018: Which Brands Are Losing Market Share?”, surveyed more than 8,000 employees at more than 600 office supply retailers.
It found that the number of office supplies sold by these retailers fell by 8% between October 2017 and September 2018, while the number purchased by consumers fell by 7%.
“These declines were particularly pronounced among the retail stores that are the most frequently cited as being the best-performing brands, including Office Depot, Home Depot, OfficeMax, Staples, Office Maxx, and Office Max,” said the report.
The researchers, who analysed the retailer’s annual report, found that Office Depot has lost 7% of its market share since the beginning of the year, while Home Depot lost 4%.
OfficeMax is now the second-best-performing brand, with sales up 8%.
OfficeMax also lost 7%, Home Depot 3%, OfficeMaxx 2% and Staples 3%.
The survey found that while HomeMax and Staples saw a decline in the number purchases per employee, Office Depot experienced the largest growth.
The firm’s sales increased by a staggering 81% over the past year, with the majority of that growth coming from the acquisition of a $20bn (€16bn) stake in OfficeMax.
The company’s annual sales grew by 21% over that same period, but the share of employees who purchased their office supplies from the company declined by 14%.
The report also found that Staples had a strong year, rising by 11% over 2017.
However, it found that it was struggling to gain customers.
The firm had a market share of 9% in 2018, down from 13% in 2017, and it now has a market price of $9.60 per hour.
Home Depot had a larger market share in 2018 (17%) than it did in 2017 (11%), with a price of just under $12 per hour per employee.
The report found that these trends are not sustainable, as they could lead to a loss of around 2.5 million full-time jobs, and potentially around 100,000 permanent jobs.
The results are likely to be of concern to President-elect Donald Trump, who has vowed to shut down or “cancel” the entire US government.
In a tweet, he wrote: “We need good manufacturing jobs, not more empty factory jobs.”
