Stock rotation
Stock rotation is the discipline of prioritising the sale of older-acquired inventory before newer stock to minimise depreciation losses, particularly important in recommerce where device values decline non-linearly.
Poor stock rotation in recommerce leads to inventory that was acquired at a higher market price becoming stranded at a lower current market price, eroding the margin originally projected at intake. First-in-first-out inventory management, combined with dynamic repricing that accelerates price reductions on aging stock, is the standard approach to managing rotation in high-depreciation categories. Monitoring market price movements relative to intake cost on a per-unit basis enables targeted markdown decisions rather than blanket discounting.
The cost of poor stock rotation compounds over time. A device acquired at a 20% premium to its current market value that has been sitting unlisted for three weeks is carrying an unrecognised loss that grows each week it remains unsold. Operators who review aging inventory regularly and compare acquisition cost against current market value can identify stranded inventory early and make deliberate decisions about whether to mark down aggressively and recover cash, or hold the position based on specific market recovery expectations.
Stock rotation also affects working capital efficiency. High rotation means capital is continuously cycling through inventory, buying and selling at market prices without long holding periods. Low rotation ties up capital in depreciating assets and reduces the operator's ability to respond to new sourcing opportunities. The working capital benefit of improved rotation is often the most quantifiable justification for investing in throughput automation and dynamic repricing, since faster cycle times directly improve capital velocity and reduce depreciation exposure.
