Eliminating Subcontractor Billing Leakage — ₹56.5 Cr recovered via Continuous AI Audit
Executive summary
Deepsa ERP Connect was deployed as an AI-native auditing and transaction layer on a complex ₹800 Cr industrial refinery expansion. Computer vision and deep semantic parsing algorithms analysed thousands of monthly engineering measurement sheets, vendor line-item invoices and compliance documents. Cross-referenced against historical SAP and Oracle entries, the system eliminated rampant over-billing — unlocking ₹56.5 Cr in certified project savings.
Operational challenge
Industrial construction relies on heavily layered subcontractor networks with dynamic variable-rate structures. Legacy billing validation relied on manual random audits. At high invoice velocity, over-billing — duplicate line items, unverified extra-work claims, inflated quantities — slipped into the main ledger unchecked, inflating capex across all sectors.
Deepsa AI orchestration
Deepsa ERP Connect ran as an unblinking continuous audit overlay. It scanned every engineering drawing, physical measurement record and incoming invoice; compared physical work progress against historical data across legacy apps; flagged anomalies; and only passed verified transactions to the core accounting system for payment.
Quantitative savings
| Audit variance | Manually approved | Deepsa AI audited | Capital preserved |
|---|---|---|---|
| Over-Reported Quantities & Line Items | ₹112.0 Cr | ₹81.5 Cr | ₹30.5 Cr |
| Unverified Deviations & Scope Changes | ₹45.0 Cr | ₹29.8 Cr | ₹15.2 Cr |
| Duplicate Claims & Tax Errors | ₹28.5 Cr | ₹17.7 Cr | ₹10.8 Cr |
| Total Capital Allocations | ₹185.5 Cr | ₹129.0 Cr | ₹56.5 Cr |
Modernisation takeaway
Manual reviews cannot match a continuous AI engine running line-by-line audits. Layered intelligent transaction validation over existing databases delivers comprehensive financial security and substantial capital preservation — with zero disruption to day-to-day operations.
