Staffordshire County Council will spend £7.2m with ITnet for a one-year SAP project, while Trafford Metropolitan Borough Council has spent £4m on SAP modules.
Trafford will replace mainframes with SAP modules that include financial, procurement, work management and a customer relationship management system, which are linked using workflow tools and datawarehousing.
Staffordshire is replacing 50 legacy systems with a similar range of modules that will be linked to other public bodies in the county, such as the fire service, police, probation, courts and colleges.
Trafford's head of e-government Mark Gibbison said the key task was to modify SAP settings to match council business processes while examining those processes "to get rid of antiquated ways of working".
Ovum analyst Philip Carnelly warned of the hidden costs of such implementations. He said SAP implementations can cost up to six or seven times more than the price of the software.
