Asset Management System

We're looking to update our asset management system.  Currently we use one system for our housing stock, which enables surveyors to upload data from handheld units and provides a 60 year investment programme for business planning purposes.  Meanwhile, the GF assets are held on other systems.  Neither of these systems interface with our financial system (E5) and our fixed assets register is held on a spreadsheet.

We would ideally like one system that covers all assets, provides a FAR and interfaces with our finance system.  Is anyone using such a system or know if such a solution exists?
