I need a lightweight, browser-based solution that lets my Admin, Employee and Manager roles create and approve Cash-In / Cash-Out vouchers, record each transaction against inventory in real time and do it all through either manual forms or quick barcode scans. The flow should be simple: an employee scans or types the item, enters the amount received or spent, inventory levels update instantly and the system stores the voucher so an authorised manager can review it later. Automated daily and monthly reports are essential so I can see totals per user, per item and overall cash movement without exporting data manually. On the stock side I only need live quantity tracking and automatic low-stock alerts; no complex categorisation is required. A clean dashboard, role-based access and straightforward audit history will keep everything transparent. There is no payment gateway or external checkout—this is strictly an internal bookkeeping and stock-control tool. Deliverables • Responsive web app (desktop & tablet friendly) • User management for Admin, Employee, Manager • Voucher module with manual entry and barcode scanning support • Inventory module with live stock counts and configurable low-level alerts • PDF/CSV automated reports (daily, monthly) Acceptance is complete once I can install the solution on our own server, seed a small product list, issue vouchers from two different roles, receive an alert for a low item, and export a report that matches test data.
