[customer]Payroll Management System
A Payroll Management System Tailored to Each Business

#1. Introduction.
#2. Challenges.
- The relevant legal regulations had not been officially announced at the time of development.
Even when legal frameworks change, the system must reflect the updates precisely at the time they are officially enforced. - Complex business logic posed additional challenges in both development and testing.
#3. Solution.
- We prepared multiple database and calculation logic options in advance, tailored to different legal scenarios.
- Comprehensive documentation was created for each solution to ensure clarity and alignment across the development team.
- A wide range of unit tests was implemented to verify the accuracy of complex logic.
- Extensive test cases were created to cover all possible conditions and use cases.
#4. Achievements.
- The employee management screen was improved to allow users to select specific fields for CSV import/export, instead of handling all 300+ fields at once.
- This enhancement resulted in a 300% increase in usage of this feature.
- Reporting and Calculation Screen:
- Added new functionality to support tax deductions in accordance with the latest regulations, even in complex and conditional cases.
- The newly released functions are currently used by over 3,000 companies, and have been highly evaluated for their usability, accuracy, and timely delivery.

Due to the large number of features, formulas, and legal dependencies (both current and pending), the development process faced considerable challenges in terms of meeting tight deadlines.
