SKU (stock keeping unit): Definition, Formula & Why It Matters
Also called: Stock keeping unit
A SKU (stock keeping unit) is a unique code you assign to each distinct product or variant to track it. SKUs are seller-defined and usually encode attributes like brand, model, or condition. Each variation should have its own SKU.
Example
A used black Stratocaster might carry a SKU like FEN-STRAT-BLK-USED-01.
Why it matters for Reverb sellers
SKU-level tracking is the foundation of inventory management: accurate counts, per-item profit, sell-through, and reorder rules all depend on it. Without clean SKUs, every other metric blurs.
