Project Overview

The Contract and Billing Application is an Oracle APEX solution developed to simplify the complete lifecycle of manpower contract management. It enables organizations to create customer contracts, define multiple contract lines, capture employee time sheets, calculate overtime automatically, and generate accurate monthly billing.

Customer information is automatically populated from master data, reducing manual entry and improving accuracy. The application streamlines contract administration, minimizes billing errors, and provides a responsive interface that works seamlessly across desktop and mobile devices. The solution is designed to support approval workflows and future ERP integration while improving operational efficiency.

Business Requirements

  • Centralize customer and contract information.
  • Generate unique contract numbers automatically.
  • Support multiple contract lines under a single contract.
  • Capture employee time sheets with normal and overtime hours.
  • Automatically calculate working days and overtime.
  • Generate monthly bills directly from contract and time sheet data.
  • Reduce manual calculations and paperwork.
  • Support responsive access on desktop and mobile devices.
  • Prepare the application for approval workflows and ERP integration.

Challenges & Solutions

Problem 1 Manual contract management created duplicate entries and calculation errors, making it difficult to maintain accurate and consistent contract records across multiple clients.
Solution Centralized contract creation with reusable master data and automated calculations. Customer details are auto-populated from master records, unique contract numbers are generated automatically, and all calculations are handled by the system — eliminating duplication and errors.
Problem 2 Preparing time sheets manually was time-consuming, error-prone, and failed to properly account for weekends, public holidays, and overtime hours.
Solution Implemented automatic time sheet generation that creates daily entries, skips weekends and holidays automatically, and calculates overtime based on predefined contract rules — reducing time sheet preparation from hours to seconds.
Problem 3 Monthly billing required repetitive manual calculations across multiple contracts and employees, leading to frequent billing delays, errors, and revenue leakage.
Solution Bills are now generated automatically using approved contract rates and captured time sheet data. The system calculates totals, normal hours, and overtime amounts in real time — transforming a multi-day manual process into an instant automated output.
