Faktur – Modern Invoice Management App

Most invoice tools are either bloated enterprise software or too basic to handle real business needs. Freelancers and small businesses needed something in between: a clean, fast invoice management system that handles the full lifecycle from creation to tracking, without the overhead.

Faktur is a full-stack invoice management application that covers the complete invoicing workflow:

Invoice creation with a polished, intuitive form builder

Client management to track contacts and billing history

Status tracking for sent, paid, overdue, and draft invoices

Dashboard overview with at-a-glance metrics on outstanding and collected amounts

PDF generation for professional, downloadable invoices

Responsive design that works across desktop and mobile

The app is built on Next.js 16 with TypeScript end-to-end. I used tRPC for the API layer, which gives full type safety from database queries through to the frontend components. No more guessing what shape the data is in.

The database runs on SQLite (via Drizzle ORM for the latest version), keeping the deployment simple and self-contained. The UI uses Shadcn/ui components with Tailwind CSS, customized to create a professional, business-appropriate look.

I focused on reducing friction in the invoice creation flow. The form auto-calculates totals, tax, and line items in real time. The dashboard prioritizes actionable information: what's overdue, what's pending, and what's been collected.

The color system and typography were chosen to feel trustworthy and professional, since this is a tool people use to send to their clients.
