Multi-GSTIN practice book
Single dashboard across every client's GSTINs, return types (GSTR-1, GSTR-3B, GSTR-9, GSTR-9C), and periods. Filter by due date, return type, or filing status.
GST RETURN FILING
GSTR-1 prep, ITC reconciliation against GSTR-2B, cross-return matching, annual aggregation. You file via the GST portal.
Overview
GST compliance is an unforgiving cadence.
GST compliance is an unforgiving cadence. GSTR-1 by the 11th, IFF by the 13th, GSTR-3B by the 20th — every month, every GSTIN. The bottleneck is rarely the filing itself, it's the prep work upstream: reconciling Input Tax Credit between GSTR-3B and GSTR-2B, catching mismatches before they trigger Section 73 notices, and aggregating twelve months into a defensible GSTR-9 at year-end.
Finamize handles the preparation layer. A multi-GSTIN practice book tracks every client's filing status. The invoice register feeds into GSTR-1 prep with auto-classification into B2B, B2CS, B2CL, and Exports. The reconciliation workspace runs five-way matching across GSTR-1, GSTR-3B, GSTR-2A, GSTR-2B, and books — variance highlighted, blocked credit flagged, unclaimed credit surfaced. An AI advisor with CGST Act knowledge helps draft notice responses. At year-end, the platform aggregates monthly filings into GSTR-9 and prepares GSTR-9C for clients above the audit threshold.
Finamize is a GST practice management and preparation tool, not a GST Suvidha Provider (GSP). Prepared returns export as GST portal-ready data; you file via the GST portal directly with your Digital Signature Certificate (DSC), or through Tally, Busy, or your existing utility. The Acknowledgement Reference Number (ARN) flows back to close the loop.

Why Finamize
Why Choose Finamize
ITC reconciliation against GSTR-2B
Paste the GSTR-2B your client downloaded from the GST portal. The reconciliation engine flags mismatches between supplier filings and what the client claimed, surfacing unclaimed Input Tax Credit before you finalize GSTR-3B.
GSTR-1 preparation from invoice register
Line-level invoice register with HSN, place of supply, reverse charge, and full tax breakdown. Sales invoices auto-classify into GSTR-1 categories — B2B, B2CS, B2CL, Exports — and export as GST portal-ready data.
Cross-return reconciliation
GSTR-1 vs GSTR-3B vs GSTR-2A vs GSTR-2B vs GSTR-9 vs books — five-way reconciliation with variance highlighted. Catch discrepancies before they show up in a Section 73 notice.
AI advisor with GST expertise
AI-powered audit and reconciliation assistant trained on the CGST Act, GSTR series, and Input Tax Credit rules. Flags excess claims, surfaces unclaimed credit, helps draft notice responses under Sections 73 and 74. Insight only — final regulatory judgment is yours.
Form 3CD Clause 44 auto-fill
Tax audit Form 3CD Clause 44 (GST payable, GST paid, ITC claimed) populates from your reconciliation workspace. Less manual transcription during audit season.
GSTR-9 annual return aggregation
Aggregates monthly GSTR-1 and GSTR-3B filings into the annual GSTR-9 return. Outward supplies, ITC, tax paid, and refunds reconciled across the financial year.
GSTR-9C reconciliation statement
For clients above the audit threshold, the GSTR-9C reconciliation statement is review-ready. Variance analysis between books and filed GSTR-9; certifying CA's notes captured per line.
Notice and ARN tracking
Every Acknowledgement Reference Number (ARN) stored against the filing it covers. Notices tracked as workflow items with deadlines, including notices under Sections 73 and 74.
How It Works
Get Started in 4 Steps
1
Add client GSTINs to your practice book
Onboard each client's GSTIN. Set return type (Regular, Composition, QRMP) and frequency. Bulk-import from your existing CRM or spreadsheet.
2
Import invoices and supplier GSTR-2B
Sales invoices feed the GSTR-1 prep register. Your client uploads their GSTR-2B JSON; the reconciliation engine matches it against the purchase register.
3
Reconcile and review prepared returns
Run five-way reconciliation across GSTR-1, GSTR-3B, GSTR-2A, GSTR-2B, and books. Resolve mismatches. The AI advisor flags edge cases. Computation is review-ready.
4
File via the GST portal; record the ARN
Export GST portal-ready data. File via the portal with your DSC or through your utility. The Acknowledgement Reference Number is recorded in the practice book to close the loop.

Regulatory Framework
GST Compliance Framework in India
1
Under the CGST Act, 2017, every registered taxpayer must file GSTR-3B by the 20th of the following month (or quarterly under the QRMP scheme). GSTR-1 for outward supplies is due by the 11th of the following month; the Invoice Furnishing Facility (IFF) for QRMP filers is due by the 13th.
2
Late filing of GSTR-3B attracts a penalty of Rs 50 per day (Rs 25 CGST + Rs 25 SGST), capped at Rs 10,000 per return. For nil returns, the penalty is Rs 20 per day. Interest at 18 percent per annum applies on outstanding tax under Section 50.
3
Input Tax Credit under Section 16 of the CGST Act can only be claimed if the supplier has filed their GSTR-1, the invoice appears in the recipient's GSTR-2B, and the recipient has received the goods or services. Rule 36(4) restricts Input Tax Credit claims to invoices appearing in GSTR-2B.
4
E-invoicing is mandatory for businesses with aggregate turnover exceeding Rs 5 crore from August 2023. E-invoices must be generated on the Invoice Registration Portal (IRP) within 30 days of the invoice date.
5
GSTR-9 annual return is mandatory for all regular taxpayers above the Rs 2 crore aggregate turnover threshold. GSTR-9C self-certified reconciliation statement is required for taxpayers with turnover above Rs 5 crore.
6
GST registration is mandatory when aggregate turnover exceeds Rs 40 lakh for goods (Rs 20 lakh for services, Rs 10 lakh for special category states) under Section 22 of the CGST Act.
