Overview

An advanced invoice management and financial analytics system with automated invoice creation, PDF generation, email delivery, and comprehensive reporting.

Business Challenge

Manual invoice creation in spreadsheets caused errors, inconsistent numbering, no financial-year tracking, and hours lost to formatting PDFs.

Why It Was Built

Built to automate the full invoicing workflow — create, PDF, email, and report — so small businesses bill faster and stay compliant.

Target Users

Freelancers, traders, and small businesses that issue recurring invoices and need financial-year reporting.

Architecture

CodeIgniter MVC keeps the codebase lean; DomPDF renders invoice templates server-side; PHPMailer queues delivery; Maatwebsite/Excel handles bulk import/export; financial-year-aware sequential numbering.

Deployment

Shared-hosting compatible PHP deployment with MySQL; no special server requirements.

Scalability

Lightweight CI footprint handles thousands of invoices; Excel bulk operations offload heavy data work.
