LOP is Wolters Kluwer’s law-firm practice management solution offered primarily in France and other Francophone markets as a modular, configurable "logiciel pour avocats." The product provides functionality for matter/case management, document management, time recording, billing/invoicing, administrative operations, and performance reporting/analytics in a single platform, with optional add-on modules.
A notable difference compared with many cloud-only practice-management tools is that Wolters Kluwer indicates LOP supports on-premises data and document hosting within a law firm environment.
