In a recent survey commissioned by the company, nearly two-thirds of respondents said they reviewed their bills more closely to check their accuracy and to look to opportunities to cut them.
The most reviewed bills were found to be those from credit card and mobile phone companies.
The survey also highlighted that more consumers were delaying payments until final demands, or are more readily switching suppliers.
DST Output chief executive Tim Delahay said: "More than half the respondents questioned stated that they are looking to change service suppliers – now is the time that businesses must use every communications channel open to them effectively to keep customers loyal.
"Work with our clients has shown that businesses who invest in clever design and targeted messaging on bills and statements can reduce debtor days and improve relationships with customers."
