Grocery is a high-volume business with multiple supply chains of various levels of integration. Keeping actual inventories rectified with sales data depends on accurate billing/receiving through the back door of any specific outlet. Expected inventory vs actual inventory can easily get out of sync due to uncapturable or hard-to-capture behavior at the store level (theft and damaged products aka shrink) or product being left at the warehouse but present on an invoice (which is transmitted electronically) or even product misplaced somewhere in the backroom that cannot effectively be sold. There is constant drift between what should be at a store versus what is actually at a store and augmented ordering is usually used in lieu of automated ordering, where managers have shelf-level visibility on what is on its way, what is currently present, and what is projected to sell based on historical data using something like a Motorola Symbol Barcode Scanner running Windows CE.
