Online Invoice Generator

What is an Online Invoice Calculator?

An Online Invoice Calculator — sometimes called an Online Invoice Generator — is a browser-based tool that helps you create accurate, professional invoices without heavy software or sign‑ups. This tool lets you enter business and client details, add line items, define taxes (IGST or CGST + SGST), select currencies, apply discounts (flat or percent), include shipping/handling, add notes, and export the final invoice as a PDF. Because everything runs in your browser, you can work quickly and securely with instant visual feedback in the live preview.

• Describe items clearly: Include model, size, or service period when relevant.
• Set the right tax mode: IGST for inter‑state; CGST+SGST for intra‑state in India; use No Tax for tax‑exempt scenarios.

• Save before clearing browser data: Saves live in your browser; export PDFs for off‑device backups.

Example calculation

Suppose your subtotal is ₹22,000. You apply a 10% discount (₹2,200). Taxable base becomes ₹19,800. With CGST 9% (₹1,782) and SGST 9% (₹1,782), total tax is ₹3,564. Add shipping ₹200. Final total is ₹23,564. The Live Preview and PDF will show each component clearly so clients understand how the total is formed.
