Every shipped order generates a GST-compliant invoice with the seller's GSTIN, your billing address, and a per-item HSN + GST split.
To claim ITC
- Add your business GSTIN at checkout — there's a field on the address step.
- Make sure the billing address matches the GSTIN registration state — for inter-state, IGST applies; for intra-state, CGST + SGST.
- Place the order with the same email you'll use to file ITC; the invoice goes to that email.
Can I add a GSTIN after placement?
Once an order is placed, the GSTIN on the invoice is locked. To get a fresh invoice, cancel and reorder with the GSTIN attached.
Where's my invoice?
It's emailed when the order ships and is available any time from Account → Orders → Download invoice.
