The first CSI Lawyer version was published already 11 years ago. Since then, we have continuously developed its functionality according to our clients' needs and regulatory changes. The annual version updates have brought, for example, the review process of preliminary invoices, e-invoicing, assignment phases, sub-assignments, dashboards, mailing lists and management of customer identification. The list is long. Fewer changes have taken place in the system's user interface, although customer expectations regarding the usability have also increased.
