One of the advantages of QR and EDI is that retailers hold "leaner" inventories since they receive new merchandise more often. Yet, when merchandise is especially popular or the supply chain breaks down, stockouts may still occur. A Food Marketing Institute study found that even supermarkets, which carry more staples than most other retailers, lose 3 percent of sales due to out-of-stock goods.
From the statics data from pos equipment, we can see that: Although the pharmacy in a typical chain drugstore may occupy only 10 or 20 percent of the total square footage, it usually accounts for at least 60 percent of the stores revenues. And an average pharmacy carries $175,000 in inventory, half of which is slow-moving items. Thus, inventory management is a critical concern for pharmacies--with carrying costs constantly rising across a carousel of moving targets as new drugs are brought to market, patented drugs become over-the-counter offerings, and the shelf life of every SKU has to be monitored without exception. Logistics processes are compounded because merchandise received in bulk cases and bottles are dispensed as ounces and doses when prescriptions are filled. Pharmacists, unlike other merchants, must determine inventory replenishment based upon SKUs being depleted through incremental percentages.
