Inventory DiscrepancyInvestigation.

Act as an experienced inventory control and warehouse operations specialist.

TASK:
Investigate an inventory discrepancy between the physical stock quantity and the system quantity.

ITEM / SKU:
[Enter the item code, SKU or product description.]

SYSTEM QUANTITY:
[Enter the quantity shown in the inventory system.]

PHYSICAL QUANTITY:
[Enter the physically counted quantity.]

UNIT OF MEASURE:
[Example: each, carton, case, pallet, kg.]

WAREHOUSE / LOCATION:
[Enter warehouse, zone, aisle, rack, bin or storage location.]
COUNT TIME / CUT-OFF:
[Enter the physical count date, time and time zone, plus the system balance timestamp. Describe any movements during the count.]

STOCK SCOPE:
[Specify whether both quantities cover the same location, batch, ownership and stock status. Identify whether the system figure is on-hand or available stock.]

SUPPORTING EVIDENCE:
[List count sheets, transaction references, movement timestamps and documents actually reviewed. Separate verified records from unconfirmed reports.]

APPROVAL / ESCALATION RULES:
[Provide known approval roles and escalation thresholds. Mark anything unknown as unconfirmed.]
DISCREPANCY TYPE:
[Shortage, excess, unknown or mixed.]

VALUE / IMPORTANCE:
[Enter approximate stock value, criticality or business impact if relevant.]

RECENT ACTIVITY:
[Describe recent receipts, picks, transfers, returns, adjustments, damages or other known transactions.]

KNOWN INFORMATION:
[Add any facts already discovered.]

INVESTIGATION REQUIREMENTS:

Help plan and document the investigation using only the supplied information. Do not imply that you have inspected stock, accessed the inventory system or verified documents.

Before interpreting the difference:
- Confirm that physical and system quantities use the same unit of measure, stock scope and cut-off.
- Do not compare physical on-hand stock directly with available stock unless reservations and status differences have been reconciled.
- If quantities are comparable, calculate variance as physical quantity minus system quantity. A negative result is a shortage; a positive result is an excess.
- If they are not comparable, label the difference provisional and explain what must be reconciled.
- Separate confirmed facts, possible explanations and missing evidence.
- Treat matching transaction quantities as investigation leads, not proof of a cause.

Check the following areas:

1. PHYSICAL VERIFICATION
- Recount the stock independently.
- Confirm the correct SKU, item description, batch, lot, serial number or variant.
- Confirm the unit of measure.
- Check for mixed stock, hidden stock, loose units or partially opened cartons.
- Verify that stock has not been counted twice.

2. LOCATION CHECK
- Check the assigned system location.
- Check nearby bins, racks and overflow locations.
- Check staging, receiving, dispatch, returns, quarantine and damaged-stock areas.
- Check whether stock may have been placed in the wrong location.

3. RECEIVING TRANSACTIONS
- Review recent inbound receipts.
- Compare purchase order, delivery note and goods receipt quantities.
- Check short receipts, over receipts, duplicate receipts or incomplete system posting.
- Check whether received stock was physically stored before the system transaction was completed.

4. OUTBOUND / PICKING TRANSACTIONS
- Review recent picks, dispatches and sales orders.
- Check for unconfirmed picks or shipments.
- Check incorrect picked quantities.
- Check whether stock physically left the warehouse without the corresponding system transaction.

5. INTERNAL TRANSFERS
- Review location-to-location and warehouse-to-warehouse transfers.
- Check pending, incomplete or duplicate transfers.
- Confirm both issuing and receiving locations.

6. RETURNS
- Review customer returns and supplier returns.
- Check whether returned stock was physically received but not posted.
- Check whether returned stock was posted to the wrong location or status.

7. DAMAGED / QUARANTINE / BLOCKED STOCK
- Check damaged, expired, rejected, quality-hold or quarantine areas.
- Confirm whether the inventory system correctly reflects the stock status.

8. SYSTEM TRANSACTIONS
- Review adjustments, cancellations, reversals and manual entries.
- Check transaction dates, quantities, users and reference numbers.
- Identify duplicate, missing or incorrect transactions.

9. DOCUMENTATION
- Compare system records with physical documents where available.
- Check purchase orders, delivery notes, picking lists, transfer documents, return notes and adjustment records.
- Identify documentation errors or missing approvals.

10. TIMING / CUT-OFF ISSUES
- Check whether the physical count occurred while transactions were still in progress.
- Identify receipts, picks, transfers or adjustments posted before or after the stock count.

11. FINDINGS AND ROOT CAUSE
- For each possible explanation, state supporting evidence, conflicting evidence and the next check needed.
- Distinguish the event that explains the quantity difference from any underlying process-control failure.
- Mark the cause as unconfirmed when evidence is insufficient.
- Do not infer theft, misconduct or individual blame from a stock difference alone.

12. CORRECTION AND PREVENTION
- Distinguish a counting correction, location/status correction, missing or incorrect source transaction, and residual stock adjustment.
- If a source transaction needs correction, explain the evidence and authorization required under the supplied procedures.
- Do not propose both a source-transaction correction and a stock adjustment for the same units.
- Recommend preventive actions only where findings support them. Mark other improvements as suggestions for review.

13. ADJUSTMENT DECISION
- Do not recommend an unconditional stock adjustment from the initial variance.
- Reconcile verified movements and approved transaction corrections first.
- If a residual unexplained difference remains, state the evidence and unresolved questions for an authorized reviewer.
- Calculate any proposed adjustment only from comparable, reconciled quantities, and show the arithmetic.
- Do not invent approval authority or escalation thresholds.
- An unresolved cause must remain documented as unresolved, even if an adjustment is later authorized.

OUTPUT FORMAT:

2. Discrepancy Calculation
3. Confirmed Facts and Missing Evidence
4. Prioritized Investigation Checklist
