Frequently Asked Questions on E-Commerce GST Invoices

Calibrated to 2026 CGST Act & CBIC Guidelines

How does the tool determine whether to charge IGST or CGST + SGST?

Under Indian GST laws (Section 7 and 8 of the IGST Act), if the seller state code and buyer place of supply (POS) state code are identical (intra-state sale), tax is split equally between CGST (Central Tax) and SGST (State Tax). If they are different states (inter-state sale), the entire tax is levied as IGST (Integrated Tax).

Is my seller and customer business data stored on SellerLeak servers?

No. SellerLeak adheres to an absolute zero-server-telemetry architecture. All calculations, invoice rendering, and PDF generation happen directly inside your browser runtime. Your business profile is securely saved in your browser local storage (localStorage) for recurring convenience.

Can this tool generate 4x6 inch thermal printer packing slips?

Yes. Use the format toggle switch to toggle between standard A4 Tax Invoice format and compact 4x6 inch (100mm x 150mm) thermal label format compatible with TSC, TVS, Zebra, and generic e-commerce barcode label printers.

What mandatory fields are required for a valid GST tax invoice in India?

Rule 46 of the CGST Rules mandates: (1) Supplier name, address, and GSTIN, (2) Consecutive serial invoice number, (3) Date of issue, (4) Recipient name and address, (5) HSN code of goods, (6) Description, quantity, and unit rate, (7) Taxable value, (8) Rate of tax (CGST/SGST/IGST), and (9) Signature or digital signature of the supplier.
