What is Stocky?

Where Stocky Falls Short
Backend Inventory Planning, Not Frontend Sales Architecture
Stocky manages purchase orders and stock levels. It does not influence how customers shop, what they buy together, or how bundles are structured on the storefront.
No Bundle Builder or On-Site Offer Structure
Stocky tracks what needs to be reordered. It does not create tiered bundles, mix-and-match experiences, or progressive reward offers that move more inventory per order.
Demand Forecasting Without Demand Creation
Stocky forecasts demand based on historical sales. Tiergain creates new demand through bundle incentives. Forecasting predicts the future. Bundle architecture changes it.
Slow-Moving Inventory Needs Bundling, Not Just Tracking
Stocky identifies slow-moving products. Tiergain turns slow movers into bundle components paired with bestsellers. Identification is step one. Bundling is the fix.
