The Business
Deepak ran a mid-size industrial components manufacturing unit. Annual revenue Rs 6.8 crore, 45 employees, a long-established supplier network. The business was profitable, but gross margins had been quietly compressing for three consecutive years.
Deepak's explanation: 'Raw material prices have gone up. The market will not accept price increases. So margins have to compress.' A rational-sounding theory for what turned out to be a very different problem.
The Problem
Total identified: Rs 18 lakh over 24 months. In some cases this was billing error. In others it was opportunism. In every case, it persisted because nobody was checking.
→ Vendor A (primary raw material supplier): invoiced at Rs 100 per unit on 14 occasions against a contracted rate of Rs 92. Overcharge over 24 months: Rs 3.2 lakh
→ Vendor B (packaging supplier): regularly invoiced for 1,000 units against purchase orders of 950. Nobody had reconciled delivery notes against POs for 18 months. Total overcharge: Rs 4.6 lakh
→ Vendor C (maintenance services): billed for 15 service visits over 12 months. Maintenance logs showed 12 visits actually occurred. Three phantom billings totalling Rs 1.8 lakh
→ Vendor D (logistics partner): auto-renewed a rate card at Rs 3 per kg above current market rate. Excess cost over 18 months: Rs 8.4 lakh
The Diagnosis
→ No three-way match process: purchase orders, delivery notes, and invoices were never reconciled together
→ Vendor rate cards not reviewed annually -- contracts renewed by default without price comparison
→ Accounts team approving invoices on vendor name recognition, not document verification
→ No random audit process for a sample of vendor billings each month
→ Vendor relationships managed entirely through the owner's personal relationships -- no independent review
The Solution
Phase 1: Remediation
→ Formal communication issued to all four vendors with billing discrepancy documentation attached
→ Three vendors issued credit notes; one vendor contract terminated
→ Rs 11.4 lakh recovered through credits and adjustments; Rs 6.6 lakh beyond the practical recovery window
Phase 2: Procurement System Rebuild
→ Three-way match process implemented for all invoices above Rs 5,000 -- PO, delivery note, invoice must all reconcile
→ Annual rate card review scheduled as a calendar event for every vendor contract
→ A dedicated procurement accountability role assigned (promoted from existing team)
→ Random 10% monthly audit of vendor invoices introduced as a standing process
→ Vendor performance scorecard introduced covering price compliance, delivery accuracy, and quality consistency
Phase 3: Competitive Benchmarking
→ All major vendor rates benchmarked against two to three alternative suppliers
→ Two vendors replaced with more competitive alternatives after benchmarking revealed significant price gaps
→ Ongoing savings from benchmarking exercise: Rs 2.4 lakh annually
The Results
✓ Direct recovery from audit: Rs 11.4 lakh
✓ Ongoing annual savings from procurement reforms: Rs 3.8 lakh per year
✓ Gross margin improvement: 2.3 percentage points in 12 months
✓ Vendor compliance: 100% of contracts now formally documented with signed rate cards
✓ Phantom billing incidents in the following 12 months: zero
✓ Deepak's revised theory on margin compression: entirely resolved -- the market had not compressed margins; the vendors had
Key Lessons
In a Rs 6.8 crore business, Rs 18 lakh in leakage over 24 months represented 13% of annual net profit. It was invisible because no process was designed to see it. Checking is a business function, not a sign of distrust.
💡 The most trusted vendor is still billing you. Verify what they bill. Not because relationships are dishonest, but because billing errors -- whether accidental or deliberate -- are invisible without a process to catch them.
💡 Procurement reform is almost always high-ROI. The cost of implementing three-way match and annual benchmarking is measured in hours. The savings are measured in lakhs.
