Free Tool — GST Registered Sellers
Free GST Invoice Generator
Generate a GST-compliant tax invoice in seconds. Runs entirely in your browser — no data is sent to any server, no account required.
When do Indian sellers need a GST invoice?
If you are GST-registered, you are required to issue a tax invoice for every taxable supply. For Instagram and WhatsApp sellers, this means every order where the buyer is GST-registered or asks for a tax receipt.
A GST invoice must include: your GSTIN, the buyer's GSTIN (if B2B), invoice number and date, HSN/SAC code, taxable value, CGST and SGST rates and amounts (or IGST for inter-state), and total amount.
This generator creates a properly formatted GST invoice you can print or download as a PDF. For high-volume invoicing, OrderMatrix generates GST invoices from order records on all paid plans.
Frequently asked questions
Is this GST invoice generator free?
Yes — completely free, no email, no account, no limits. The invoice is generated in your browser. Nothing is stored on our servers.
Is this legally valid for GST purposes?
This tool generates a correctly formatted GST invoice. Legal validity depends on the accuracy of the information you enter — GSTIN, HSN code, tax rates, and invoice number. Verify your details before issuing.
Do I need to be GST-registered to use this?
You need a valid GSTIN to issue a GST invoice. If you are not GST-registered, you cannot legally issue a GST tax invoice — you can issue a regular receipt/bill instead.
What is CGST and SGST?
CGST (Central GST) and SGST (State GST) apply to intra-state transactions (seller and buyer in the same state). IGST applies to inter-state transactions. The combined CGST+SGST rate equals the GST rate (e.g., 18% GST = 9% CGST + 9% SGST).
Can I save invoices for later?
Invoices are not saved by this tool — they run entirely in your browser. Print or download the PDF before closing the page. For automatic invoice generation and record-keeping, OrderMatrix generates and stores GST invoices on all paid plans.
