On top of this, Clientbox offers a modular set of features, including CRM, invoicing, time tracking, calendar, task boards, and HR tools like absence and leave management. Because every module can be enabled per user, companies can tailor Clientbox to their exact needs. Clientbox helps businesses centralize their client communication and replace multiple standalone apps with one easy-to-use system.
