1. Document Control Block

2. Executive Summary & Scope

This SOP defines the standardized methodology for conducting a comprehensive physical inventory audit within all Template Registry managed facilities. The objective is to reconcile physical assets against digital ledger records in the Enterprise Resource Planning (ERP) system to maintain 99.8% inventory accuracy. This procedure applies to all raw materials, work-in-progress (WIP), and finished goods. Compliance with Sarbanes-Oxley (SOX) reporting requirements and GAAP inventory valuation standards is mandatory.

3. Prerequisites & Tool Requirements

• Software Access: ERP Terminal Access (Read/Write to 'Inventory_Audit_Module'), Barcode Management System (BMS).
• Equipment: Industrial-grade handheld RFID scanners (Model: TR-Scan-X), calibrated weigh scales.
• Safety PPE: ANSI-rated steel-toe footwear, high-visibility vest.
• Certifications: Active 'Inventory Control Specialist' (ICS) certification or higher.

5. Step-by-Step Operational Procedure

Phase I: Preparation & Lockdown

• Notify all departments of the 24-hour "Inventory Freeze" (no stock movement allowed).
• Perform a system backup of the current ERP inventory snapshot.
• Clear all pending inbound/outbound shipments in the BMS.

Phase II: Execution & Counting

• Initialize "Audit Mode" on the ERP portal to lock item masters.
• Distribute zone assignments to counting teams; verify scanner calibration.
• Perform first-pass count of all SKUs; record deviations via RFID scan-logs.
• Conduct blind second-pass counts for any SKU where Variance > 0.

Phase III: Reconciliation

• Export raw scan data to the Audit Dashboard for automated variance calculation.
• Investigate root cause for any SKU variance exceeding +/- 0.5% tolerance.
• Draft the "Discrepancy Resolution Memo" for Finance approval.

---

6. Quality Assurance & Verification Criteria

• Tolerance Threshold: Absolute variance must not exceed 0.2% of total inventory value.
• Acceptance Benchmark: 100% of "High-Value" assets must be accounted for without variance.
• Verification: Final sign-off requires secondary review by the Operations Manager and one member of the Finance Dept.

7. Practical Troubleshooting Scenarios

Scenario A: System Mismatch (Ghost Inventory)

• Observation: System shows 50 units in stock; physical count yields 0.
• Action: Check "Transaction Logs" for the last 30 days to identify unauthorized movement or unrecorded sales. If no log exists, trigger a 'Shrinkage Incident Report' and perform an immediate write-off in the ERP.

Scenario B: Hardware/Scanner Failure

• Observation: RFID scanner battery depletion or firmware hang during active count.
• Action: Immediately isolate the current zone. Swap to redundant hardware. Synchronize the faulted scanner’s local cache to the server once connectivity is restored to prevent data duplication.

Scenario C: Label Discrepancy

• Observation: Barcode on shelf matches Item A, but physical unit is Item B.
• Action: Halt activity in the specific aisle. Tag both units as 'Quarantine - Under Review'. Initiate a retrospective trace to verify if the mislabeling occurred at the receipt or put-away stage.
