GSTR-1 Filing FAQ

What buyers ask.

IFF (Invoice Furnishing Facility) for QRMP filers. Supported?

Yes. QRMP-eligible filers can choose to upload B2B invoices monthly via IFF. The system drafts the IFF upload from the same invoice book and pushes via the authorised GSP at the prescribed cut-off.

Amendments. How are they handled?

Amendments to invoices already filed in a prior period auto-populate Section 9A (CDNR amendments) of the next GSTR-1. The original invoice retains its filed status; the amendment posts as a new line.

Multi-GSTIN filing. Is each one separate?

Each GSTIN files its own GSTR-1. The dashboard rolls up status across GSTINs so the controller sees who is pending, drafted, signed off and filed at a glance.

What if the GSP is down at filing time?

The system queues the filing call and retries with exponential backoff. ARN capture happens on success. Most filings complete within minutes; the rare GSP outage (typically end-of-day on the 11th) is handled by retry.
