A good fit looks more like operational complexity than a revenue number.
The strongest clients have enough SKUs, supplier uncertainty and inventory value that one-size-fits-all rules stop working.
Industrial distribution
Large catalogs, supplier variation, branch inventory and constant replenishment decisions are a strong fit for quantitative review.
Manufacturing
Raw materials, components and finished goods compete for cash while production still needs protection from supplier and demand swings.
HVAC / electrical / plumbing supply
Seasonality, broad product catalogs and branch-level availability make blanket inventory rules especially expensive.
Building materials
High inventory value, uneven movement and meaningful supplier lead times create real working-capital tradeoffs.
Specialty wholesale
Diverse catalogs are exactly where averages stop being useful and item-level behavior starts to matter.
Multi-location operations
Useful when one branch has excess, another has a shortage, and a transfer may beat another purchase order.
Complexity matters more than company size.
A $5M distributor with 2,000 SKUs and $800k in inventory can have a more valuable optimization problem than a much larger business with simple operations.
