Executive Mandate Summary

The business grew from Rs 80 lakh to Rs 4.5 crore in two years, but its internal controls had not evolved with its scale. An annual audit identified Rs 14 lakh of errors across inventory valuation, marketplace reconciliation and vendor payments. Northrop mapped 11 control gaps and designed practical controls around returns processing, marketplace reconciliation and three-way vendor matching. The framework was implemented using the existing team and systems. Within six months, returns processing lag fell from 23 days to 3 days, marketplace variance reduced from Rs 4.8 lakh to below Rs 40,000, duplicate vendor payments fell to zero, and audit errors declined by 91%.

Key Transaction & Governance Challenges

  • •
    The business had grown from Rs 80 lakh to Rs 4.5 crore while continuing to operate largely with the control practices designed for its smaller scale.
  • •
    The business was processing approximately 3,000 orders per month, 200 returns, 45 vendors, 12,000 SKUs and transactions across four marketplace channels.
  • •
    Returns received at the warehouse were not consistently reflected in the accounting system, creating an average 23-day processing lag.
  • •
    Marketplace payouts were accepted at face value without reconciling commissions, returns and penalties against order-level data.

Northrop Execution Architecture & Methodology

1
Northrop mapped each significant process as it actually operated, rather than relying on documented descriptions.
2
Returns physically received at the warehouse were being processed in the accounting system after an average of 23 days.
3
Marketplace payouts were accepted at face value rather than reconciled against order-level data.
4
Payments could therefore be processed when the invoice arrived rather than when the business confirmed that the goods had actually been received.

Section 1 - The Central Issue

The business had grown from Rs 80 lakh to Rs 4.5 crore in two years. The controls had not changed at the same pace.

At Rs 80 lakh, founder review and informal knowledge of vendors and warehouse activity could provide significant oversight. At Rs 4.5 crore, the same approach had to support thousands of transactions across multiple warehouses, vendors and marketplace channels.

Section 2 - Process Mapping

Northrop mapped the complete transaction lifecycle from marketplace order receipt through financial close.

The objective was to identify where a transaction could move through the business without an independent check or timely documentation.

This exercise identified 11 control gaps.

Section 3 - Controls Designed Around the Existing Team

Rather than designing an enterprise-scale control system, Northrop designed controls that could be executed by the existing two warehouse staff, one accountant and the founder.

The controls were not ERP-dependent. They were process-dependent: a defined action, performed by a defined person, at a defined point and producing a defined record.

Section 4 - Returns Control

Every physical return is entered into a returns register on the day of receipt. The accountant processes the corresponding accounting entry within 48 hours, with a weekly reconciliation between the register and the books.

This reduced the return-processing lag from 23 days to 3 days.

Verifiable Institutional Outcomes & Value Realized

  • The average processing lag between warehouse receipt and accounting recognition was substantially reduced.
  • Aggregate annual marketplace reconciliation variance was reduced through weekly order-level reconciliation.
  • The three-way matching control eliminated duplicate vendor payments during the measured period.
  • Errors identified in the following year's annual audit fell by approximately 91%.

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.
