The difference between running manual VLOOKUP calculations on Day 19 and automated audits on Day 14.
Log in to multiple client portal accounts. Manually download JSON files. Spend hours converting JSON to raw Excel rows.
Run manual VLOOKUP models. Compare supplier GSTIN, Invoice Numbers, and Tax Heads. Deal with typos (e.g. `Apex Steel` vs `Apex Steel Ltd`) failing formulas.
Identify mismatches and call/email suppliers. Realize they haven't filed, but since it's Day 19, they can't upload invoices in time for this cycle.
File GSTR-3B with estimated ITC figures. Claim unverified credits under client pressure, causing high risk of DRC-01C automated tax notices.

ITC Goes Unclaimed Annually
Indian businesses lose thousands of crores every year due to manual matching errors and missing invoices in GSTR-2B.
In DRC-01C Notices (FY2025)
The GST department has drastically ramped up automated notices for ITC mismatches between GSTR-2B and GSTR-3B.

GSTR-2B is an auto-drafted ITC (Input Tax Credit) statement generated for every registered person based on the information furnished by their suppliers in GSTR-1, GSTR-5, or GSTR-6. It indicates whether the ITC is available or not available for a specific month.
To reconcile GSTR-2B with your purchase register, you need to match each invoice's GSTIN, invoice number, date, and tax amounts. TaxSolver automates this by directly fetching GSTR-2B from the GST portal and comparing it against your ERP data (like Tally or Zoho) using advanced matching algorithms, eliminating manual VLOOKUPs.
If the Input Tax Credit claimed in GSTR-3B exceeds the eligible ITC available in GSTR-2B by more than the allowed margin, the GST portal will automatically issue a DRC-01C notice. You must reply within 7 days and either explain the difference or pay the excess ITC along with Section 50 interest.
We integrate through government-certified GST Suvidha Providers (GSPs) including Sandbox.co.in. The connection uses standard two-factor OTP authentication. Access tokens generated from the OTP handshake are AES-256-GCM encrypted and automatically expire in compliance with GSTN security mandates.
Our parser handles Excel (.xlsx, .xls) and CSV files. It automatically maps over 30 common accounting column header configurations (including standard exports from Tally Prime, Zoho Books, Busy, SAP, and QuickBooks).
Our primary reconciliation matching is 100% deterministic (GSTIN + Invoice Number + Financial Period). For records with typos, the engine drops back to a configured fuzzy string matching algorithm on the vendor's trade name. Fuzzy matches are highlighted for human approval.
The reconciliation worker automatically queries historical GSTR-2B data. If a supplier files an invoice late, the system flags it as 'Matched (Cross-Period)' and suggests appropriate adjustments to prevent double-claiming.
After you approve the reconciliation job, the system compiles the final compliance figures into the exact schema required for GSTR-3B Table 4 (Eligible ITC, Ineligible ITC, ITC Reversals). You can review the totals and upload the finalized draft to the GST portal in one click.
