About Invoice Generator

Invoice Generator helps freelancers, consultants, agencies, and micro-SaaS teams create polished invoices without spreadsheets or paid invoicing apps. You can fill sender and client details, auto-generate or edit invoice numbers, manage dates, add multiple line items, set tax and discount values, and export a professional PDF in one flow. The live preview is designed to mirror exported output so you can review layout before sharing with clients. Because the tool stores drafts in localStorage, your data remains on your device and can be restored later without creating an account. It is ideal for fast monthly billing and one-off project invoicing workflows where speed, trust, and clear presentation matter.

Key Features

  • Full Invoice Data Model

    Capture business details, client details, invoice meta fields, item rows, taxes, discounts, and payment terms in one form. This avoids fragmented billing workflows across multiple tools.

  • Live Professional Preview

    The preview panel updates as you type and reflects invoice structure including totals and notes. This reduces mistakes before sending a client-facing PDF.

  • PDF Export

    Exports a clean, professional invoice PDF with sectioned layout and summary totals. PDF generation is loaded only on demand for better runtime performance.

  • Draft Save and Restore

    Store invoice state locally and reload it later with one click. Useful for recurring clients and staged edits.

  • Currency Flexibility

    Switch between USD, GBP, EUR, CAD, AUD, and PKR. All totals and line amounts recalculate in the selected currency format.

  • Keyboard and Accessibility Friendly

    Every field is labeled and works with keyboard navigation, including touch-friendly controls on mobile screens.
