Which reports do I need?

Amazon: MTR B2C and MTR B2B (plus the GST/TCS report for reconciliation). Flipkart: the Sales Report and GSTR/TCS report. Meesho: tcs_sales and tcs_sales_return. Download them as they are — no editing.

Is my sales data safe?

Your marketplace reports are processed on your device and never uploaded. They are read in your browser, and only the return totals, any fixes you make and a copy of each filed return are saved to your account.

What if a report has mistakes?

We flag missing HSN codes, invalid buyer GSTINs, unrecognised states and rate mismatches. You fix them inline before the return is generated.

I file quarterly under QRMP. Does it work?

Yes. Choose quarterly during setup and upload the three months together, or use IFF for B2B invoices in the first two months.

How much does it cost?

Creating an account and previewing your return is free, and so is your first return for each GSTIN. After that, unlock a return when you are ready to file: ₹99 for a monthly return or ₹199 for a quarterly one, per GSTIN. A yearly pass costs ₹999 for monthly filers or ₹699 for quarterly filers. Prices exclude 18% GST, and nil returns are free.

Can my CA use it for several clients?

Yes. Add each client’s GSTIN; each return is paid for on its own or covered by that GSTIN’s yearly pass, and the client list shows each one’s filing status.

Your marketplace reports never leave your device

Marketplace reports contain every order, customer state and price you sold at. GST Hero reads them inside your browser, so the reports themselves are never uploaded to us. Only the finished return is saved to your account.
