How it works

From invoice book to filed return.

Step 01

Auto-populated from books

Every section of GSTR-1 (B2B, B2CL, B2CS, exports, SEZ, CDNR, advances, amendments) drafted automatically from invoices, credit notes and debit notes posted in the period.

Step 02

Validation before filing

GSTIN status, place-of-supply, HSN summary, document totals validated. Errors surfaced before the GSP call.

Step 03

CA review and DSC sign-off

CA reviewer access reads the full draft. Comments captured. DSC sign-off captured per period before filing.

Step 04

Filed via authorised GSP

Filing pushed via authorised GSP API. ARN captured automatically. Response posted back to the audit trail.

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.
