System Ratio, for 40 years a reference point for tax, management and labor updates in a schematic and operational form, is now also mobile with a series of new services:

- Ratio Sfera: all the editorial documents of the Ratio System in digital, multimedia and hypertext format. Personalized selection, with the possibility of aggregating and sorting in all simplicity.
- Subscriber Area: The subscription to a Ratio System service allows access to this area that contains the last exit and the backlog of active services. For paper periodicals, the issue of a number is made available the same day as the closing date in Editorial Office, some days in advance of receipt by post. All documents are searchable by free search or by keyword and can be downloaded in PDF format for any use or sharing.
- Ratio Quotidiano: the commentary and criticism of the Ratio System experts on the most important events in the sector.
- Schedule: the right tool to always keep professional and personal deadlines under control.
- How to defend yourself from the Tax Office: the practical guide to deal with problems and relationships with the Tax Administration.
