About

Fresh Invoices is a fully functional, browser-based invoice generator that helps you create professional invoices quickly and easily. It was born from a simple need: creating invoices without being tied to payment services like Stripe or Wise.

With Fresh Invoices, you can:

Create invoices from scratch or from templates
Upload existing invoice PDFs for AI analysis
Generate invoice details from natural language descriptions
Save invoices locally in your browser
Export invoices as PDFs
Duplicate and modify previous invoices
Track payment status with receipt mode

Features

AI-Powered Invoice Generation

Simply describe what you need ("Create an invoice for 3 hours of web development at $95/hr") and the AI will generate a complete invoice with appropriate line items, taxes, and payment details.

PDF Upload and Analysis

Upload existing invoice PDFs and the AI will extract relevant information to create a new invoice based on the uploaded document.

Local-First Storage

All data stays in your browser. No server-side storage means your invoice data remains private and accessible even offline.

Undo/Redo Support

Built with Alpine.js and Immer for robust state management, allowing you to easily undo and redo changes as you work.

Receipt Mode

Toggle between invoice and receipt modes to track payment status and details.

QR Code Generation

Automatically generate QR codes for payment links to make it easier for clients to pay.

PDF Export

Export your invoices as professional PDF documents ready to be shared with clients.
