Multi-level storage hierarchy
Inventory always lives at bin level, never at a vague warehouse address. A mixed pallet broken into two hundred units stays findable, one unit at a time.
Storage runs five levels deep: Zone, then Aisle, then Rack, then Level, then Bin. A warehouse holds many zones and each level holds many of the next.
Lay the hierarchy over your real layout. A path reads as Z1, A1, R1, L1, B1, so anyone can walk to a unit from the label alone.
Every unit is assigned to a bin, never to a rack or a zone. That is what makes a graded return traceable after the pallet is broken down.
Add zones as the building fills and expand aisles, racks, and bins as you need them. The structure holds as volume goes up.
