ZKTeco Payroll & Attendance System

A business-focused workforce management system designed to connect employee attendance, leave management, payroll processing and reporting into one integrated platform.

Project Overview

From attendance data to payroll decisions

The ZKTeco Payroll & Attendance System is a Laravel-based business application designed to manage workforce attendance and convert verified working-time information into structured payroll calculations.

The system brings together employee records, attendance processing, leave management, payroll calculations, approvals, payroll locking and reporting within a centralized platform.

The project is designed around practical business workflows rather than simply recording attendance. The objective is to create a reliable process from employee attendance through payroll preparation and finalization.

The Challenge

Turning workforce records into reliable payroll information

Attendance information alone is not enough for payroll. Organizations need a structured process that considers working hours, overtime, leave, authorized corrections, attendance exceptions and payroll rules.

01

Attendance

Capture and process employee attendance records while identifying missing or exceptional attendance situations.

02

Workforce Rules

Apply working-hour, overtime, leave and attendance resolution rules consistently.

03

Payroll

Transform processed workforce information into structured payroll calculations and reports.

The Solution

An integrated workforce management workflow

The system is structured around a workflow that allows attendance information to move through validation, resolution, leave processing and payroll calculation.

This approach helps separate raw attendance records from verified business decisions, creating a more controlled payroll process.

Workflow

1 Employee Attendance
2 Attendance Resolution
3 Leave & Work Calendar
4 Payroll Calculation
5 Approval & Payroll Lock
