Quotabase-Lite is an open-source web application for small-business quotation workflows. I integrated customers, products and services, quotations, states, and receipts using native frontend code, PHP, and MySQL/MariaDB.
My work
- Business workflow: Connected customer management, catalog data, quotation creation, and status tracking.
- Amounts and transactions: Stored amounts as integer cents and used database transactions for related writes.
- Frontend and backend: Implemented PHP with limited Composer dependencies and native HTML/CSS/JavaScript, including tab navigation and dark mode.
- Basic safeguards: Used PDO prepared statements, CSRF checks, and output escaping without claiming an independent security audit.
- Print and receipts: Built A4 print views, personal receipts, and QR/hash verification entry points.
- Export and deployment: Supplied CSV/JSON exports and installation documentation within a lightweight, framework-free architecture.
