Inventory, warehouse & supply chain
Inventory shrinkage: causes, measurement and prevention for Philippine retailers
Measure and reduce inventory shrinkage from theft, administrative errors, supplier fraud and damage, with controls for stores, warehouses and transfers.
Inventory shrinkage is the difference between the inventory your records say you should have and what you physically have. It comes from theft (internal and external), administrative errors, supplier shortfalls and damage. For retailers and distributors with thin margins, a shrinkage rate of even one or two percent of sales can wipe out a meaningful share of profit. The good news: most shrinkage can be traced to process gaps that systems and controls can close.
How to measure shrinkage
Shrinkage rate = (recorded inventory value − actual inventory value) ÷ sales for the period
Measure it at least at every full count, and by location and category. Cycle counts give you a running view between full counts (cycle counting).
Main causes and controls
| Cause | Examples | Controls |
|---|---|---|
| Employee theft | Taking goods, sweethearting (giving away items to friends at checkout), fake refunds | Segregation of duties, refund approvals, POS exception reports, bag checks, CCTV |
| Customer theft | Shoplifting | Store layout, security tags, staff presence at high-risk areas |
| Administrative errors | Wrong item codes, unit of measure mistakes, unrecorded transfers or returns | Barcodes, item master control, transfer receiving confirmation |
| Supplier shortfalls | Short deliveries signed as complete | Count at receiving against the delivery receipt (receiving) |
| Damage and spoilage | Breakage, expiry | Proper storage, FEFO picking, recorded write-offs |
| Transfer losses | Goods lost between warehouse and branch | In-transit tracking and blind receiving (stock transfers) |
POS exceptions that signal problems
POS data is one of the best shrinkage detection tools. Review by cashier and branch:
- Voids and cancellations after the sale
- Refunds without receipts or with frequent same-day refunds
- Price overrides and manual discounts
- "No sale" drawer openings
- Sales of very cheap items paired with expensive ones in the same transaction
A cashier with three times the average refund rate deserves a conversation. See X and Z readings and cashier reconciliation.
Store and warehouse practices
- Limit access to stockrooms and high-value cages
- Gate passes for any goods leaving the premises (gate pass guide)
- Bag and vehicle checks under a clear, respectful policy
- Damaged goods area with records and approval for disposal
- Receiving dock control: only receiving staff accept deliveries, and only against open POs
Investigating shrinkage
- Identify the locations and categories with the highest shrinkage.
- Check administrative causes first: unposted transfers, returns and unit errors often explain a large part.
- Analyze POS exceptions and adjustment history for the same items and period.
- Review CCTV and access logs for specific high-loss items.
- Interview staff and document findings; involve HR and legal before any disciplinary action, following due process.
Building accountability
Publish shrinkage by branch monthly. Include it in branch managers' KPIs alongside sales and margin. When managers know shrinkage is measured, they pay attention to receiving, transfers and refunds. Read KPI examples by department.

Frequently asked questions
What is a normal shrinkage rate?
It varies widely by industry, product and location. Track your own baseline by branch and category, and focus on reducing it over time.
What is the biggest cause of shrinkage?
It differs by business. Retailers often find a mix of theft and administrative errors; distributors often find receiving and transfer errors. Measure before assuming.
How do you reduce employee theft?
Segregate duties, require approvals for refunds and adjustments, review POS exceptions, control stockroom access and investigate patterns promptly.
Is shrinkage tax-deductible?
Inventory losses may be deductible under specific conditions and documentation requirements. Consult your tax adviser.
