Making a professional invoice doesn't have to be complicated or expensive. With RupaX, you can generate beautiful, compliant invoices directly in your browser without spending a dime.

Step 1: Set up your business profile

First, head over to the Create Invoice section. You'll need to enter your basic business details:

  • Your Company Name and Address
  • Your GSTIN (if applicable)
  • Your Logo (optional, but recommended for a professional look)

The best part? RupaX stores this data securely in your browser's local storage. This means your data never leaves your device and you won't have to enter it again next time.

Step 2: Add your line items

Next, add the products or services you are billing for. For each item, you can specify:

  • A clear description
  • Quantity and Rate
  • Tax percentages and discounts

RupaX uses highly accurate integer-precision arithmetic to calculate all totals. This completely eliminates those annoying floating-point rounding errors that can mess up your accounting.

Step 3: Generate and Download

Once everything looks good, simply hit the download button. RupaX uses advanced client-side PDF generation (via html2pdf.js) to instantly create a print-ready PDF of your invoice.

No waiting for server uploads, no premium watermarks—just a clean, professional invoice ready to send to your clients.
