A few years ago i was part of the technical team and we implemented a similar RMS for Botswana's Ministry of Finance. MDY File Surf which later on was bought by Computer Assosciates and now bought again by Autonomy and now known as Autonomy Records Manager.
I stand to be corrected, this is the best in the whole world.
Autonomy Records Manager helps organizations manage, control and discover physical, electronic and email information assets located across the enterprise, to achieve proactive information governance driven by the every-changing array of regulatory, legislative, and business requirements. By automating record keeping processes and policy enforcement across all content, Autonomy Records Manager helps organizations save time and money, while empowering users with faster access to the right information at the right time.
Independent of infrastructure, content location, language, format or status, Autonomy Records Manager provides the ability to protect and control information from one central console while reducing risk of noncompliance. Autonomy Records Manager systematically decreases the amount of information managed, based on approved retention policies, while facilitating transparency, accountability and defensibility.Through the power of IDOL, Autonomy Records Manager can automatically create taxonomies, records categories, file plans based on the corpus of data, import an existing taxonomy, or allow users to train the records categories or file plan so that IDOL can automatically identify content across all respositories in an organization that should be managed as records.
Should you want a complete tried and tested solution i recommend you try it and acquire it. It has evolved into a perfect solution and has acquired numerous industry awards.
FYI this will pay for itself in the long run by cutting costs and improving operational efficiency and effectiveness.You can track any record i.e. any receipt,any invoice, any news paper anything and everything considered as a record even emails etc.
