University Finance

This web-based financial system is designed to streamline campus payment management with high accuracy and strict validation processes. It integrates student data seamlessly, ensuring every transaction is well-tracked and secure. Built with modern technologies, it delivers a fast, reliable, and user-friendly financial management experience.

Authentication & Authorization: • Single Sign-On (SSO) authentication via Google OAuth — no manual passwords, seamless login using campus accounts • Automatic role detection based on email domain (students and staff identified instantly) • Role-Based Access Control (RBAC) with granular permissions for each feature (Spatie Laravel Permission) • Secure session management with auto-expiration, CSRF protection, and maintenance mode during system updates

Bill Management: • Bulk bill generation — create hundreds of invoices in one click based on filters (batch year, study program, student type) • Duplicate prevention — automatically skips existing records for the same (academic year + student ID + payment type) • Pre-generation preview — review targeted students before confirming bill creation • Automatic synchronization between billing and penalty records using Observer pattern — all changes stay consistent in real time

Validation & Audit: • 3-stage validation workflow: pending → approved/rejected for clear and controlled processing • Bulk payments are automatically approved without manual validation queue to improve financial efficiency • Comprehensive audit trail capturing validator, timestamp, and detailed allocation (principal + penalties) • Validation history with advanced filters (student ID, name, payment type, date, status) and scalable pagination (50–1000 rows per page)

Student Display: • Mobile-friendly student dashboard with inline PDF preview (Google Docs Viewer fallback for mobile devices) • Automatic profile picture sync from Google — always up to date without manual uploads • Structured activity menu combining bill payments, transaction history, and announcements in one place

Data Integrity: • Database transactions across all multi-step operations — automatic rollback ensures data consistency on failure • Observer pattern for automatic synchronization between related tables (tagihan → tagihan denda) • Idempotent seeder — safe to run multiple times without creating duplicate records • Manual resync feature available as a safety net to handle potential data inconsistencies
