The Top 5 Causes of Inventory Loss in FMCG
Spoilage, theft, data drift, supplier variability, and bad planning — why margin leaks and how operators close the gaps before audit season.
A branch manager found dated stock tucked behind a fast-moving SKU last Tuesday — the write-off hit before anyone had time to argue about whose count was right. Inventory loss is the quiet tax on FMCG and retail health businesses. It rarely shows up as one dramatic event; it accumulates as spoilage, miscounts, process drift, and slow decisions. The patterns below show up across categories — and they connect directly to how you rotate stock (FEFO vs FIFO discipline) and how fast you flag slow movers.
Knowing the rule is not the same as seeing the next risk date in one place — which is exactly what Expiry Desk tracks automatically →

What is Expiry and spoilage (the clock problem) (in FMCG inventory work)?
Short-dated stock, promotional overstocks, and poor rotation turn shelves into timed bombs. Loss is not only the written-off carton — it is the labour, shelf space, and opportunity cost of replacing stock you should never have carried past its useful window.

Dense packs and mixed strengths are where hand counts lie — unless you are using a camera to count them for you →
What this means on the floor
Strong teams pair rotation rules with aging and velocity reviews so purchasing sees risk before the stock room does.
How to handle Data drift, theft, and handling loss on the floor
Duplicated SKUs, spreadsheet drift, and partial receipts without line-level capture create phantom stock. Teams reorder against ghosts until a stocktake exposes the gap — often too late for margin.

Spreadsheets age faster than stock — most people track this wrong. Here is the smarter way →
How to validate this in your next stock review
Treat unexplained variance as a signal: separate shrink from process failure so purchasing and store ops each own a lever.
Rotation only works when the soonest date is visible before the truck arrives — here is how teams close that gap →
Why Planning and promotions that overshoot demand matters for cash and service levels
Over-ordering for promos, slow movers bundled with fast movers, and optimistic forecasting leave you holding risk. Tie purchasing to what the shelf actually says, not only last month’s spike.

If your reminder lives on a sticky note, it does not survive a busy service — this is what an expiry reminder looks like when it scales →
Why this signal should reach finance the same week
When loss is visible early, finance stops treating write-offs as a surprise line item — and the business can invest in prevention instead of reconciliation theatre.

- What should we fix first in inventory control?
- Start where value and risk overlap: high-value lines expiring in the next 30 days, then enforce FEFO, weekly cycle checks, and owner-based actions.
- How often should inventory teams review risk?
- At minimum weekly for operations and monthly for finance. Teams with high expiry volatility should run a short daily risk huddle.
