Frequently Asked Questions About GST Invoicing
What details are legally mandatory on a GST Tax Invoice?
Under Rule 46 of the CGST Rules 2017, a valid GST invoice must include 16 mandatory fields: supplier name, registered address, GSTIN, consecutive invoice number (max 16 chars), invoice date, recipient GSTIN/address, HSN/SAC code, item description, quantity/UOM, taxable value, tax rates, CGST/SGST or IGST tax amounts, Place of Supply with state code, delivery address (if different), reverse charge flag, and authorized signature.
How is Intra-State vs Inter-State GST calculated automatically?
GSTInvoicer inspects the first 2 digits of the Supplier's GSTIN against the Place of Supply (or Buyer GSTIN state code). If both state codes match (e.g. 27-Maharashtra to 27-Maharashtra), it splits the tax into equal CGST and SGST shares (e.g. 9% + 9% for 18% GST). If state codes differ, it applies IGST (18%).
Can I save items or create new items on the fly during invoicing?
Yes. While creating an invoice, you can choose from your pre-saved catalog items or enter custom line items on the fly. You can check 'Save to Catalog' to immediately add new items to your reusable catalog for future bills.
Does GSTInvoicer generate dynamic UPI payment QR codes?
Yes. Every invoice includes a dynamic NPCI-compliant UPI QR code embedded directly alongside bank details, allowing buyers to scan with PhonePe, Google Pay, Paytm, or BHIM and pay the exact balance amount.
How can I export or print the invoice as a PDF?
The invoice is styled with precision CSS print media queries (@media print). Clicking 'Print / Save as PDF' renders an exact, border-perfect A4 replica matching the statutory Vyapar/Tally format ready for instant browser PDF saving.
