On-Shelf Availability

Using our AI software to track inventory balances, brick-and-mortar retailers can identify and fix in-store operational issues, improve On-Shelf Availability and Visibility, and restore sales up to 2%.

Check our new video about OSA!


  • The average worldwide Out of Stock (OOS) rate in retail is about 8.3% and it is reason for the loss of around 4% of sales.

  • About 25% OOS events are caused by shelf OOS, when the product was actually in the store, 47% events are caused by not accurate demand forecasting and ordering, 28% events are caused by other factors - mainly suppliers.

  • The level of coincidence of actual and accounting stock balances is 35–45% of cases. Presence of "phantom inventory" is the major contributor to 47% store ordering root cause.

  • Shoppers encounter stock outages, empty shelves, price confusion, and other similar obstacles to purchase in as many as one in three shopping trips.
