The fear of technology not working is the biggest fear for British small businesses, with electronic crime not causing much concern.
Research covering almost 600 firms employing fewer than 50 people showed that attitudes to operational business anxieties were dominated by technology.
The research, commissioned by security software firm Trend Micro, saw 42% of respondents cite technology not working as their biggest fear.
The same figure said difficult clients and suppliers increased their anxiety, along with heavy workloads (30%), tight deadlines (26%) and long hours (19%).
When questioned about business-related crime, only 10% expressed concern about the loss of confidential data.
And when asked about electronic crime, 83% said they had not been a victim of electronic crime in the last 12 months.
