Frequently Asked Questions
What makes this different from other free invoice tools?
Live PDF preview (most free tools make you download to check), UPI QR embedded directly on the invoice (so your customer scans and pays the exact amount), e-Invoice JSON export in the official GSTN Schema 1.1 (free competitors gate this behind paid plans), 5 visually distinct templates, plus draft history and a product library: all 100% free, 100% in-browser, no signup.
Does the invoice include a UPI payment QR code?
Yes. Enter your UPI ID under More options and the QR is generated with your exact invoice amount pre-filled per the NPCI UPI URI spec (upi://pay?pa=...&am=...). The customer scans, GPay/PhonePe/Paytm opens with the amount already filled in: they just hit Pay. The QR is embedded in the PDF, not just shown on the screen.
What is e-Invoice JSON export and who needs it?
Under CBIC Notification 70/2020 and subsequent amendments, businesses with aggregate turnover > ₹5 Cr must register their B2B invoices on the Invoice Registration Portal (IRP) to get an IRN (Invoice Reference Number) and QR. The portal accepts a JSON in the official Schema 1.1. We generate that JSON (including TranDtls, SellerDtls, BuyerDtls, ItemList, ValDtls) ready to upload to the IRP or pass to your GSP/ASP.
How does CGST/SGST vs IGST work?
If the seller and buyer are in the same state, CGST + SGST apply (split equally: for an 18% rate, that's 9% CGST + 9% SGST). If they're in different states, IGST applies at the full rate (18%). The tool detects this automatically from the state dropdowns. You can override via 'Place of Supply' if you're billing intra-state but shipping inter-state.
Are my invoices and customer data uploaded anywhere?
No. Everything (form data, PDF generation (via html2canvas + jsPDF), UPI QR generation, e-Invoice JSON) runs locally in your browser. Drafts, customer list and product library are stored in your browser's localStorage. Your invoice details are never uploaded; only the tool's own code loads when you first export.
Which invoice types and templates are supported?
Eleven document types, including Tax Invoice, Proforma, Credit and Debit Notes, Bill of Supply, Delivery Challan, vouchers, Self-Invoice and Export Invoice, each with the correct title. Six visual templates, including PSU / Tally: Classic (amber + serif), Modern (gradient header), Minimal (B&W print-friendly), Corporate (navy + gold for BFSI/consulting), and Creative (vibrant gradient for agencies). The preview updates instantly when you switch.
Can I save customers and products to reuse?
Yes. Save the buyer with one click: next invoice, click their name chip to autofill. Same for line items: hit Save next to any item to add it to your Product Library (description, HSN, unit, rate, GST rate). The Products tab lets you re-add any saved item with one tap. Up to 50 products and 30 customers stored locally.
Does the PDF render the ₹ rupee symbol correctly?
Yes. Older jsPDF-only tools fall back to 'Rs.' because the default Helvetica font lacks the ₹ glyph (U+20B9). This tool renders the invoice as HTML using your system fonts (which all support ₹), then captures it to PDF via html2canvas, so the rupee symbol renders perfectly. No font embedding needed, no missing-glyph boxes.
GST invoice kaise banaye?
Form bharo: seller, buyer, items with HSN code, quantity, rate, GST slab. Right-side preview live update hota rahega. Template choose karo (6 options). 'Download PDF' click karo: bilkul wahi PDF download hoga jo preview me dikha. UPI ID daloge to QR bhi PDF par aayega: customer scan karke pay kar lega.
