Everything you need to know about creating GST invoices online for free in India.
Q: Is this GST invoice generator really free?
Yes, 100% free. There are no hidden charges, no watermarks on your PDFs, and no account required. You can generate unlimited GST invoices at no cost — forever.
Q: Does this tool store my invoice data?
No. All data you enter is processed entirely within your browser. Nothing is sent to or stored on any server — your business information is completely private.
Q: What is the difference between CGST+SGST and IGST?
CGST + SGST applies to intrastate transactions (buyer and seller in the same state), split equally. IGST applies to interstate transactions (different states), charged in full by the central government. ZooXo auto-applies the correct tax based on Place of Supply.
Q: Can I use this invoice for Input Tax Credit (ITC)?
Yes. Select "Tax Invoice" as the document type. A valid Tax Invoice with the supplier's GSTIN is required for the recipient to claim ITC under GST rules. ZooXo generates a fully ITC-compliant tax invoice.
Q: What is an HSN or SAC code?
HSN (Harmonised System of Nomenclature) is an 8-digit code for goods. SAC (Services Accounting Code) is a 6-digit code for services. Both are mandatory on GST invoices to classify what is being sold. ZooXo includes an HSN/SAC field for every line item.
Q: Can I add my company logo to the GST invoice?
Absolutely. Click the logo upload area in the invoice form to add your business logo. It appears prominently on the printed or downloaded PDF, making your GST invoices look professional and branded.
Q: How do I download the GST invoice as PDF?
Click the "Download PDF" button in the sidebar or header. Your browser's print dialog opens — select "Save as PDF" to save a clean, watermark-free invoice to your device. Works on Chrome, Firefox, Safari and Edge.
Q: Can freelancers without GST registration use this tool?
Yes. If your turnover is below ₹20 lakh, GST registration is not mandatory. Use the "Invoice" type and leave the GSTIN field blank. You can still create professional invoices for your clients at no cost.
Q: What types of GST documents can I create?
ZooXo supports: Tax Invoice (for ITC claims), Proforma Invoice (advance quotation), Quotation (estimate), and Debit Note (additional charges). All are GST-compliant formats.
Q: Is ZooXo mobile-friendly for generating GST invoices?
Yes. ZooXo is fully optimised for smartphones and tablets. The invoice form adapts to any screen size and the Download PDF button is always accessible via the fixed bottom bar on mobile.
