# Personal Development Project
A web-based business system that centrally manages the entire procurement workflow—from purchase request application and approval, formal purchase order (PO), partial receipt, inspection, inventory accounting, accounts payable, to payment—as mutually traceable Records.

Key Features

• Full Workflow Visibility: Confirm in a single flow "who needs what, who approves it, which PO is issued, how many units are received and inspected, and how much is recorded as inventory and paid"
• Multi-Level Approval Support: Automatically generates and manages multiple approval steps based on amount and department
• Partial Receipt & Multiple Deliveries: Multiple receipts can be added for a single PO, with remaining quantities and excess receipts automatically calculated
• Inspection Variance Recording: Records good items, defects, shortages, and excess at the line-item level, making discrepancies visible
• Accounts Payable & Payment Management: Automatically calculates payment deadlines from supplier payment terms, tracks from partial payments to full settlement
• Supplier Performance Analysis: Automatically derives on-time delivery rate, defect rate, average lead time, and more
• Audit Log: Records all business operations chronologically with CSV export capability
• Segregation of Duties: Five roles—Requester (requester), Approver (approver), Purchasing (procurement), Accounting (accounting), Admin (administrator)

Target Users

• Manufacturing and wholesale companies handling procurement operations
• Organizations operating multi-department, multi-approver purchase processes
• Companies wanting to integrate supplier management and payment management
