About Invoice Generator
Generate 100% compliant Indian GST Tax Invoices, Non-GST Bills, and Bills of Supply in seconds with the FastFreeTools Invoice Suite.

Frequently Asked Questions
Is this invoice generator compliant with Indian GST laws?
Yes! The generated invoices include all mandatory fields specified under Rule 46 of the CGST Rules, 2017: consecutive serial number, 15-digit GSTIN, state codes, HSN/SAC codes, taxable amounts, and separate tax columns for CGST, SGST, and IGST.
How does the tool calculate CGST, SGST, and IGST?
The tool automatically compares the Supplier State Code with the Place of Supply (Buyer State). If they match, it calculates Intra-State tax split into 50% CGST and 50% SGST. If they differ, it applies 100% IGST. You can also manually toggle Inter-State mode.
Does the UPI QR code allow customers to pay directly from the PDF?
Yes! When you input your UPI ID (VPA), the tool encodes a standard NPCI UPI payment URL with your business name, invoice number, and exact grand total into a QR code. Clients can scan it with Google Pay, PhonePe, Paytm, or BHIM to pay instantly.
Can I turn off GST and generate a simple Bill of Supply?
Yes! In the Options & Feature Toggles card, you can switch Document Title to "BILL OF SUPPLY" or turn off GST Tax Mode for non-GST billing.
Does the invoice include a place for company stamp and signature?
Yes. The invoice features a dedicated stamp and seal zone alongside an authorized signatory line where you can apply a physical rubber stamp and wet signature, or upload a digital signature image.
How does Amount in Words handle Lakhs and Crores?
The tool uses the standard Indian numbering system (Lakhs and Crores, e.g., "INR One Lakh Twenty-Five Thousand Only") instead of Western Millions and Billions.
Are my financial transactions or invoice data uploaded to any server?
Never. All PDF compilation and QR code generation execute 100% locally inside your web browser sandbox. No invoice data, client names, or financial numbers ever leave your device.
Is FastFreeTools responsible for the invoices generated?
No. This utility is provided strictly for legitimate business record-keeping and billing. Users are solely responsible for ensuring the accuracy and legal validity of their invoices.
