Step 1: Enter Business Details

Start by adding your business name, address, and contact information. Add your tax ID (EIN, GSTIN, VAT number) if you have one, or leave it blank. Set your invoice number and date to keep your records organized.

Pro Tips:

  • - Use sequential invoice numbers (INV-001, INV-002, etc.)
  • - Keep your business address complete for legal compliance
  • - Add your business email and phone for client communication

Step 2: Upload Logo (Optional)

Make your invoice look more professional by uploading your business logo. This builds brand recognition and trust with clients. Logos appear at the top of all invoice templates.

Best Practices:

  • - Use PNG format with transparent background for best results
  • - Keep logo simple and readable at small sizes
  • - Recommended size: 200x200 pixels or similar aspect ratio

Step 3: Add Client Information

Enter your client's name and complete billing address. Clear client details ensure your invoice reaches the right person and helps with payment tracking.

  • - Price: Rate per unit (automatically calculates total)
  • - Or use the AI Generator to auto-fill from a project description
