Purchasing & Procurement Management System

The Purchasing & Procurement Management System is a complete business solution designed to manage and control the entire procurement process, from purchase requests and supplier quotations to purchase orders, receiving, invoicing, payments, and supplier performance evaluation.

The system includes a comprehensive Purchase Requisition (PR) module with configurable multi-level approval workflows. Approval rules can be based on purchase amount, department, branch, cost center, project, product category, user, or role. Sequential, parallel, delegated, and conditional approvals can be configured to match different organizational structures.

Once a purchase request is approved, users can create Requests for Quotation (RFQs) and invite multiple suppliers to submit quotations. Suppliers can respond directly through the Supplier Portal and attach quotation documents. Purchasing teams can then compare suppliers based on price, discounts, taxes, shipping costs, lead times, payment terms, warranty conditions, historical pricing, and supplier ratings.

The system supports Purchase Order creation from PRs, RFQs, supplier quotations, or direct purchases. Purchase Orders include approval workflows, revisions, version tracking, partial orders, and document generation for printing, downloading, or sending directly to suppliers by email.

Receiving management includes Goods Receipt, Service Receipt, partial receiving, quality inspection, and purchase returns. Users can clearly track ordered quantities, received quantities, rejected items, and outstanding deliveries.

The finance module supports supplier invoices linked to Purchase Orders and receiving records. A built-in 3-Way Matching process compares Purchase Orders, Goods Receipts, and Supplier Invoices to identify discrepancies before payment approval.

Payment management supports payment status tracking, transfer proof uploads, QR Code payments, manual payments, and future payment gateway integration.

Budget Control enables organizations to control purchasing budgets by fiscal year, department, branch, cost center, project, or product category. The system tracks allocated, reserved, consumed, and remaining budgets and can be configured to issue warnings, require additional approval, or block purchases when budgets are exceeded.

Supplier Management provides a centralized database for supplier profiles, documents, contracts, payment terms, credit terms, lead times, transaction histories, and purchasing performance. Suppliers can be evaluated based on pricing, quality, delivery, service, responsiveness, and documentation through Supplier Scorecards and Supplier Rankings.

The Supplier Portal allows vendors to view RFQs, submit quotations, confirm Purchase Orders, provide delivery schedules, upload invoices and delivery documents, and review payment status through a dedicated external interface.

Real-time dashboards provide visibility into pending purchase requests, approvals, active RFQs, outstanding quotations, open Purchase Orders, overdue deliveries, invoices, pending payments, budget consumption, and supplier performance.

The solution includes comprehensive reporting and analytics for purchase spending, supplier performance, purchase price history, cost savings, outstanding Purchase Orders, budget utilization, procurement cycle time, supplier lead time, and purchasing trends.

The public website includes a flexible Layer and Widget Page Builder. Administrators can create different page layouts, move widgets through drag-and-drop controls, rearrange content, configure displayed columns, and customize individual widgets. A WYSIWYG content editor is provided for visual content management.

Thirty built-in theme presets are included, along with support for administrator-created custom themes. Public and administration interfaces can be customized with colors, navigation styles, headers, footers, sidebars, icons, and visual components.

Advanced Role-Based Access Control supports administrators, head staff, purchasing managers, purchasing officers, requesters, approvers, warehouse staff, accounting, finance, auditors, suppliers, customers, and custom roles. Security features include CSRF protection, XSS prevention, SQL injection protection, brute-force protection, secure sessions, audit logs, error tracking, and security monitoring.

Additional built-in modules include Live Chat with image sharing, Ticket Management, Contact Us, Notifications with badges, News Management, Media Library, Backup and Restore, Read-Only Database Viewer, Maintenance Mode, Demo Mode, and Production Readiness monitoring.

The system supports subscription-based and source-code buyout licensing through an integrated license manager and can be extended in the future for SFTP-based license updates.

A built-in Deployment Center allows system updates through overlay ZIP packages. Each update can include files, SQL migrations, update scripts, version information, syntax verification, deployment logs, and rollback functionality, making future updates and maintenance easier and safer.

The system is developed with PHP 8.0 and MariaDB and is designed to work on Windows/XAMPP environments during development while remaining compatible with both Linux and Windows production servers.
