I need a secure, web-based system that lets me record every sale, track consignment items, and see at a glance how much cash is still outstanding. The application will live online, but access must be restricted to a single admin login—no public or multi-user tiers are required. Core workflow • I enter a new sale with invoice number, customer details, item list, total bill value, and payment terms. • For items supplied on consignment, I must log the quantity delivered, the quantity already sold, and the amount collected so far. • The dashboard should immediately show total bill value alongside any pending balance, with a clear status flag (paid / partially paid / unpaid). Key features to build 1. Sales record management: create, edit, delete, and search invoices. 2. Consignment tracking: per-item quantity and money received, with automatic calculations. 3. Pending bill tracking: real-time summary of outstanding amounts, filterable by date range or customer. I am comfortable if you build this with common stacks such as PHP-Laravel + MySQL or Node.js + React + PostgreSQL—use whatever you work fastest in, as long as the code is clean and documented. Mobile responsiveness is a plus, but native mobile apps are not required. Acceptance criteria • Admin login page with password encryption. • Intuitive forms for sales and consignment entries. • Dashboard showing total bills, paid amounts, and pending balances. • Export of records to CSV or Excel. • Deployed to my hosting or delivered with setup instructions I can follow in under 30 minutes. If you have a ready-made module that can be adapted quickly, let me know; otherwise, outline your suggested tech stack and timeline when you bid.
