The government has played down the speed with which public sector jobs should come into force.
Speaking in his budget the Chancellor Alistair Darling talked about the need to keep spending plans on track and protect "front line services".
He said that efficiencies would contribute to keeping public sector job cuts down but admitted that it had already identified cuts of £20bn by cutting pay and making savings, "We need to identify savings across the entire public sector."
Resellers targeting the public sector have expressed concerns that a change of government will impact spending in local government, education and the NHS.
But he was confident that economic growth, which it was convinced would start to pick up speed, would also filter through and make it less urgent to swing the axe in the public sector.
Government departments will start to unveil later today how they intend to make savings.
"Reducing the size of bloated departments can be easily achieved without damaging front line services if public sector chiefs utilise IT to cut costs and free-up staff," said Alan Smith, senior vice president UK & Ireland UC4.
"Huge savings can be made by automating complex process in the back office, liberating staff from manual workloads and allowing them to concentrate on delivering a better service to the public," he added.
