ABC–XYZ Classification: Prioritise the SKUs That Actually Move the Needle
Segment SKUs by value and demand variability so counting effort, safety stock, and review cadence match real risk.
Shrink rarely arrives as a single theft headline. It accumulates in expiry drift, miscounts, and decisions made on yesterday’s numbers. ABC–XYZ segmentation splits SKUs by value (or margin) and demand variability so counting effort, safety stock, and review cadence match real risk — not a one-size blanket policy. It is the bridge between finance’s view and service-level targets on the ground.
Key terms in this guide: Days on hand, Inventory turnover, ABC analysis.
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 →

Referenced signals — spot-check sources as data ages
Amplifies
Forecast error compounds up the supply chain (bullwhip): ordering policies and lead times inflate swings vs end demand.
Cash tied up
Inventory often represents 20–35%+ of total current assets for product companies — small % improvements move real cash.
1.6%
US retail shrink as % of sales in NRF’s 2023 survey (FY 2022) — industry benchmark; methodology & definitions vary by retailer.
What is ABC: where the money sits (in Analytics inventory work)?
Class A items are few but material; they deserve tighter controls, more frequent counts, and executive visibility when variance appears.

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 this means on the floor
B and C items still matter for shelf presence — but you cannot afford the same cadence everywhere without burning out the team.
How to handle XYZ: where the forecast breaks on the floor
X SKUs are relatively stable; Z SKUs swing wildly. Safety stock and reorder logic should differ — otherwise you chase noise every month.

How to validate this in your next stock review
Pair this view with turnover and days on hand so velocity does not hide trapped capital.

Why this signal should reach finance the same week
When the same SKU jumps classes after a promo or a new competitor, update policies — static labels create static blind spots.
