One in three entrepreneurs is wasting too much time on pointless tasks, holding back their business, according to new research.
They are spending too much time on minor administrative details, instead of trying to drive ahead with revenue growth and sales, the research said.
And good time management is the key to small business success, it claimed, with two out of three business start-ups in the UK failing.
Too many business owners have to invest their own time in general office activity like organising transport, fixing IT problems, ordering and managing general office supplies, the research from car rental firm Rent-A-Car said.
UK business development manager Rob Ingram said: "The SME sector is the engine room of the UK economy, with tens of thousands of entrepreneurs working every day to propel their companies to success.
"For many of these individuals, there aren't enough hours in the day - what these figures have shown is that many of them could be creating time for themselves by using their day more effectively.
"Often, the financial outlay of outsourcing non-core activities can seem daunting, especially for some of the greener start-ups. But this has to be weighed against the time it takes to manage these activities yourself. If you can free up 10 per cent of your time in the year, that could translate to more business wins, newer products and better service for your customers.
"Bring the right partners on board and make sure you get the most for your money."
