The Ministry of Justice is looking for a contractor for an £85m shared services programme.
The ministry wants to build a "common operating model" for its back-office systems, including human resources, finance, purchase and payroll systems.
It wants the shared system to be rolled out by spring 2013. The common operating model will be supported by an in-house shared services organisation, which the MoJ says will deliver transactional and professional services using a single enterprise resource planning (ERP) platform and technology stack.
The department is looking for three separate strands of the work to be completed. It wants systems integration and service management, business applications implementation and maintenance, and infrastructure and hosting.
The contract will cost the MoJ between £65m and £85m and it expects the work to take five years, although there will be the option to extend the work by anything up to another four years.
The MoJ wants to receive all tenders by 15 March, and it will come up with a shortlist in April.
