Case Study: GST Reconciliation Crisis Before a Bank Renewal
Resolving Rs 22 lakh of GST mismatches within a 30-day bank renewal window
Executive Mandate Summary
Key Transaction & Governance Challenges
- •Financial statements, GSTR-1 and GSTR-3B reported different revenue figures.
- •Mismatches had accumulated over 18 months rather than being identified and corrected monthly.
- •The differences arose from credit-note timing, incorrect B2B/B2C classification, estimated GSTR-3B filings and rounding/timing differences.
- •The borrower had only 30 days to reconcile the differences before the facility renewal could potentially be deferred.
Northrop Execution Architecture & Methodology
Section 1 — The Central Issue
The bank required a clean GST reconciliation as part of the working-capital facility renewal. The financial statements showed Rs 7.5 crore of revenue, compared with Rs 7.72 crore in GSTR-1 and Rs 7.38 crore in GSTR-3B.
The resulting Rs 22 lakh difference needed to be explained within the bank's 30-day renewal window.
Section 2 — Why the Mismatch Developed
The accountant had filed GST returns on time, but the returns were inconsistent with each other and with the books. Causes included credit notes reflected in later periods, incorrect B2B/B2C classifications, estimated GSTR-3B figures and accumulated rounding differences.
Each individual difference was explainable. Collectively, they produced a Rs 22 lakh gap.
Section 3 — 18-Month Reconciliation
Northrop extracted data from Tally, GSTR-1 and GSTR-3B and reconciled the records at invoice level.
The exercise identified Rs 8.4 lakh of credit-note timing differences, Rs 5.1 lakh of B2B/B2C classification errors, Rs 4.8 lakh of estimated GSTR-3B figures and Rs 3.7 lakh of rounding and timing differences.
Section 4 — Remediation
The identified mismatch categories were remediated during Week 2. Amendments were filed for credit-note timing differences and B2B/B2C classifications, while GSTR-3B figures were corrected to actuals for the two estimated months.
A detailed 18-month reconciliation statement documented the books figure, GSTR-1 figure, GSTR-3B figure, cause and remediation for each difference.

- Rs 22 Lakh GST Mismatch Reconciled
- 18 Months of Transactions Reconciled

Case Study: Ghost Trainees and Unverified Placements in a Skill Development NGO
A skill development NGO reported that 1,200 youth had been trained and 840 placed in jobs under a programme funded through a ₹1.4 crore CSR contribution. The reported 70% placement rate prompted an independent review of beneficiary records, training delivery, placement claims and programme expenditure. Northrop Management Private Limited conducted a forensic verification covering beneficiary deduplication, attendance records, direct beneficiary calls, employer confirmations, offer letters, salary claims and the underlying financial trail.
