GST Invoice Requirements for Amazon & Flipkart Sellers

If you sell on Amazon, Flipkart, Meesho or any similar marketplace, GST registration is mandatory regardless of your turnover — the usual ₹20 lakh threshold that applies to other small businesses and freelancers doesn't apply to you. Your invoices also carry extra weight: the platform deducts TCS on your sales and reports it separately, so your own invoice records need to line up with theirs.

Why is GST registration mandatory for marketplace sellers with no turnover exemption?

Most GST-registered businesses only need to register once their aggregate turnover crosses ₹20 lakh (₹10 lakh in special category states) — see our guide on getting started with GST invoicing for that general rule. E-commerce marketplace sellers are a specific carve-out: the requirement to register applies from the very first sale, with no turnover-based exemption. If you're selling through Amazon, Flipkart, or a comparable platform, plan on registering before you list your first product, not after you hit a threshold.

What is TCS, and why does it change how invoices matter?

E-commerce operators are required to deduct Tax Collected at Source (TCS) — currently 1% — on the net taxable value of supplies made through their platform, and remit it to the government, reporting the detail via their own return (GSTR-8). As the seller, you can claim credit for that deducted TCS against your own GST liability — but only if your own sales and invoice data matches what the platform reported for you. This is the practical reason invoice accuracy matters more for marketplace sellers than it might for a freelancer billing a handful of clients directly: a mismatch between your records and the platform's reporting is what creates reconciliation problems, not just a single wrong invoice.

What does a compliant marketplace-seller invoice need?

The core requirements are the same Rule 46 fields every GST tax invoice needs — see our full GST invoice format checklist for the complete list. Two fields are worth extra care specifically because of the volume and reconciliation angle:

• HSN codes — see our HSN & SAC codes guide for the digit-count rules based on your turnover. A wrong or inconsistent HSN code across many orders compounds into a real classification problem at reconciliation time.
• Place of supply — since marketplace orders ship across many different states by default, getting the CGST/SGST vs. IGST split right on every single order matters more here than for a business with a handful of regular, geographically stable customers.

Worked example: reconciling a month of marketplace sales

What this guide doesn't cover

This guide is scoped to invoicing specifically — marketplace sellers also file the standard GSTR-1 (outward supplies) and GSTR-3B (summary) returns like any other GST-registered business, and reconciling TCS credit claims is its own detailed process. Both are worth covering with a tax professional or a dedicated return-filing resource; getting the invoice right is the foundation those returns are built on, which is why it's covered here.

Common mistakes to avoid

• Assuming the ₹20 lakh general registration threshold applies to marketplace selling — it doesn't.
• Using an inconsistent HSN code for the same product across different listings or over time.
• Not reconciling your own sales records against the platform's TCS reporting each period, and only noticing a mismatch at return-filing time.
• Treating every order the same way regardless of the customer's state — the CGST/SGST vs. IGST split still applies per order.

Confirm current TCS rates and marketplace-specific obligations on the GST portal, since these are set by notification. When you're ready to create invoices, QWIK INVOICE's invoice generator handles the HSN field and CGST/SGST/IGST split automatically per order.
