Shrinkage investigation
A negative count variance is not yet proof of theft or final loss. Shrinkage investigation starts by proving the item, quantity, cutoff and transaction history, then preserving evidence without accusing people from an incomplete record.
Direct answer
Investigate inventory shrinkage by opening a case only after an independently verified physical-to-book variance remains unexplained. Freeze the exact cutoff and record warehouse, zone, bin, SKU, variant, lot or serial, unit, ownership, status, physical count, reconstructed book quantity and value basis. Preserve first count, blind recount and count conditions. Review receipts, putaway, picks, packs, shipments, transfers, returns, rework, samples, write-offs and late postings before calling units missing. Search adjacent locations, similar SKUs, pack conversions and equal-and-opposite variances. Build an access and custody timeline from authorized records, but restrict personal data and do not treat access alone as evidence of wrongdoing. Classify the supported cause as transaction timing, wrong identity or location, count error, process damage, unrecorded disposal, supplier or carrier shortage, customer or return issue, system failure, suspected theft, confirmed theft or unresolved loss. Escalate possible criminal, security, safety or insurance matters through qualified internal and external channels; keep operational investigation separate from accusation. Obtain approval for any inventory and financial adjustment using segregation of custody, recording and approval duties. Track recovery, claim or correction once. Close when quantity and ledger treatment are authorized, evidence is retained and controls such as access, scanning, staging, count design or supervision are improved and tested.

Record case ID, reporter, date, location, product identity, unit, ownership, status, count and reconstructed balance. Preserve the initial count, independent recount and photos or package evidence. Confirm the same cutoff and units are compared. Do not label a difference as shrinkage when an open receipt, transfer or shipment can still explain it.
Limit movements where practical, preserve system logs and source documents, identify affected lots or serials and prevent routine cleanup from overwriting evidence. Record who collected each item and when. Restrict access to personal, security and commercial data. Follow legal and human-resources requirements before reviewing surveillance, devices or employee records.
Trace opening balance, receipts, putaway, replenishment, picks, packs, shipments, transfers, returns, samples, repairs, rework, disposal and adjustments. Check timestamps, effective dates, package and unit conversions. Search wrong bins and similar identities for offsetting differences. Test whether integration or scan failures created a book error rather than a physical loss.
Map the period, physical areas, custodians, system roles, overrides and exceptional access relevant to the missing population. Look for unsupported movements, broken seals, repeated adjustment patterns or control gaps. Access shows opportunity, not responsibility. Avoid naming an individual as cause without evidence and authorized investigative process.
Choose a supported category: timing, count, identity, location, unit conversion, process damage, unrecorded disposal, supplier shortage, carrier event, customer return, system failure, suspected misconduct, confirmed loss or unresolved. Record evidence for and against the conclusion and confidence. Separate root cause from the point where the difference was discovered.
Calculate quantity and value under finance policy and record inventory, financial, insurance, supplier, carrier or other recovery treatment. Use independent authority and avoid duplicate recovery. Report possible crime or regulated loss through the required channels; do not conduct unauthorized confrontation or promise a legal outcome. Keep disputed and unrecovered amounts visible.
Address access, segregation, location design, scanning, staging, receiving, picking, returns, disposal, system interfaces, count frequency or supervision as evidence indicates. Assign owner and date. Monitor shrinkage by location, product, event and period using a stable definition. Verify effectiveness through later counts and transaction testing rather than assuming training alone solved it.

Before you send the request
It is an unexplained reduction between recorded and actual inventory after valid transactions and errors are considered. Organizations should define the measure and scope consistently.
No. Timing, count error, wrong identity or location, units, damage, unposted movement and system failures can create differences. Theft should not be concluded without evidence and proper process.
The role authorized by inventory and finance policy, with custody, transaction recording and adjustment approval separated where practical or supported by mitigating controls.
Use evidence from cases to improve access, segregation, scans, locations, receiving, picking, returns, disposal, system interfaces and independent counts, then test whether recurrence falls.
Keep the request specific
Inventory differences can involve employment, privacy, surveillance, insurance, tax, criminal and reporting issues. This page is an operational control, not investigative authority or legal advice. Follow local law and qualified security, HR, legal and finance direction; preserve fairness and confidentiality.
