How does the tool decide between CGST/SGST and IGST?

The tool automatically detects the Place of Supply. If the Supplier state and Customer state are the same (Intra-State), it splits the tax into equal CGST and SGST. If the states are different (Inter-State), it applies IGST automatically.

Is my customer and business financial data stored on your server?

No. All invoice generation and calculations run 100% client-side inside your browser. Zero financial data is ever sent to or stored on Jemixo servers. Your business profile can be optionally saved in your local device browser.

How does the dynamic UPI QR code on the invoice work?

When you enter your UPI VPA ID (e.g., yourname@okhdfcbank), the tool generates a standard NPCI UPI payment QR code containing your exact grand total. Customers can scan it with PhonePe, GPay, or Paytm to pay instantly.

Is this invoice legally valid under Indian GST rules?

Yes. The generated invoice adheres to standard GST Rule 46 requirements: including Supplier and Buyer GSTINs, sequential invoice numbering, HSN/SAC codes, tax rate breakdown, and state codes.

Frequently Asked Questions — GST Invoicing in India

How does CGST, SGST and IGST work?

When goods or services are supplied within the same state (Intra-State), tax is equally split into CGST (Central GST) and SGST (State GST). When supplied across state borders (Inter-State), single IGST (Integrated GST) is levied. Our tool detects this automatically based on your selected State codes.

What is an HSN / SAC Code?

HSN (Harmonized System of Nomenclature) is a 4, 6 or 8-digit international coding system for physical goods. SAC (Services Accounting Code) is used for services. Under GST, mentioning HSN/SAC codes is mandatory on tax invoices based on business turnover.

How does the dynamic UPI QR Code function?

Our tool embeds an NPCI-compliant UPI payment intent string into a high-density QR code. Whenever you add line items or modify prices, the QR code automatically updates with the exact grand total, enabling customers to scan and pay without typing your amount or VPA.

Is my billing and client data confidential?

100% confidential. All calculations, invoice formatting, and PDF rendering take place locally inside your browser silicon. Zero financial data is ever uploaded or transmitted to our servers.
