ERP (Enterprise Resource Planning) is an integrated information system that enables businesses to manage core processes such as finance, accounting, human resources, payroll, procurement, inventory, production, and sales through a shared database. ERP systems bring together data generated across different departments in a central structure, helping information flow remain consistent, traceable, and up to date. This allows businesses to manage operations more efficiently, plan resource utilization, and rely on a common source of data in decision-making processes.

Payroll management is often perceived in many organizations as merely a wage calculation process. In reality, however, it represents a much broader and more multidimensional framework. Payroll is a critical process through which the employer fulfills its financial obligations to employees while also interacting directly with tax and social security systems.

Accurate monitoring of working hours is one of the most critical pillars of modern labor law and human resources management. With the widespread adoption of digitalization, remote work, and flexible employment models, the concept of "working time" has ceased to be limited solely to the time physically spent at the workplace; instead, it has become a strategic element that must be measured, evidenced, and managed. This transformation has elevated Personnel Attendance Control Systems (PDKS) from a purely operational tool to an indispensable infrastructure component in terms of payroll accuracy, legal compliance, and organizational efficiency.
