The company's managing director, Jason Francis, says that public sector organisations are buying fleet management software systems because they fear that future budgets will be drastically cut due to the impact of the recession, and they believe the technology will prove to be a cost-effective investment.

Meanwhile, private sector organisations and small and medium-sized vehicle leasing and rental companies that may have deferred system acquisition due to the recession are opting to invest again as the economy improves, said Mr Francis.

'The discussions that we are continuing to have with small, medium and large fleets across the public and private sectors in the first four months of this year is at levels we have not experienced in the almost seven years we have been trading,' he said.

'Latent demand built up across all organisations in the second half of 2008 and throughout 2009 as business investment was put on hold.

''Now the purse strings are increasingly being released and that is particularly true in the public sector where budget holders know that any further delays in purchasing will almost certainly be hit by forthcoming financial constraints.

'Simultaneously, public sector fleets, such as the Oxfordshire-headquartered South Central Ambulance Service which is just implementing our Key2 Vehicle Management system, have recognised that software investment will deliver significant efficiencies.'
