Moodle Platform Customization
April 29, 2025
Challenge
A rapidly-growing private-sector company needed a simple, auditable way to prove that every employee had read and acknowledged mandatory internal documents.
Solution
Krabu Grupp extended the customer’s Moodle learning environment with a custom Document Sign-Off plugin. Once an employee finishes reading, they set the status to Done; the system instantly stores the user, timestamp and document version and feeds the data into a real-time compliance report.
What is Moodle?
Moodle is an open-source Learning Management System (LMS) used in more than 200 countries to build e-learning courses, manage content and track learner progress.
Impact
• 100 % visibility of employee acknowledgements
• Sign-off cycle shortened from days to minutes
• Automatic audit trail exports for HR and compliance teams
