GST Auto Invoice: India
GST invoices on every paid order. GSTR-1 ready. Zero typing.
What it does
GST Auto Invoice turns every paid Shopify order into a GST-compliant tax invoice the moment it is paid: CGST/SGST or IGST worked out from your GSTIN and the customer’s state, HSN codes per product, sequential numbering per financial year, and a PDF your customer can download from the order status page, their account, or a WhatsApp/email link. Refunds become credit notes automatically. At month end, export GSTR-1 (B2B, B2C, HSN summary, Table 13), GSTR-3B, Tally XML or Zoho CSV in one click.
Built for Indian D2C stores: digital goods at 18%, clothing lower slab, COD fees, exports under LUT, B2B buyer GSTIN.

FAQ
Which orders get an invoice?
By default every order the moment it is marked paid. You can switch the trigger to fulfilment or order creation, and assign invoices manually or in bulk to older orders.
How does the app decide CGST/SGST vs IGST?
It compares the state code in your GSTIN with the customer’s place of supply. Same state gives CGST + SGST; a different state gives IGST; exports can be issued under LUT or with IGST.
What happens on a refund?
On Starter and Pro a credit note is created automatically, including partial and multiple refunds. The original invoice is never changed. On Free the refund is logged and no credit note is created.
Can my customers download the invoice themselves?
Yes. The PDF is available from the order status page and the customer account, and a signed, expiring link can be included in Shopify emails. Pro adds WhatsApp delivery and sending from your own mailbox.
What happens to my data if I uninstall?
Access is revoked immediately and all store records are deleted 48 hours later when Shopify sends the shop/redact webhook. GST law requires you to retain invoices, so export them before uninstalling.
Is this tax advice?
No. The app applies the GSTIN, HSN codes, rates and settings you configure. Verify documents and reports with your tax professional before filing. See the Terms of Service.
