Invoicely — Simple Invoicing System

Invoicely is a complete invoicing system built for freelancers and small agencies who need to create, track, and send professional invoices without a bloated SaaS subscription. Save clients once and reuse them across invoices, build invoices with dynamic line items, tax, and discounts, and track each one through Draft, Sent, Paid, Overdue, and Cancelled statuses — overdue invoices are flagged automatically. Every invoice renders as a clean, print-ready layout with a one-click "Print / Save as PDF" button using the browser's built-in print-to-PDF — no PDF library or dependency required. Includes a guided 5-step web installer that checks server requirements, tests your database connection, creates all tables automatically, and sets up your business details and admin login — no manual SQL import or config editing required. Includes: dashboard with outstanding/paid totals, client management, invoice creation with dynamic line items, status filtering, business settings (name, address, currency, invoice number prefix), and secure authentication with hashed passwords and prepared statements. Built with PHP, MySQL, and vanilla JavaScript — no frameworks required. Comes with a detailed README covering installation, customization, and security notes.
