The best method to manage your pharmacy’s inventory is known as perpetual inventory. Under this method stock quantities are constantly updated in conjunction with replenishment and dispensing. As such, pharmacy staff will always know what stock levels are to allow for better inventory management decisions. To take the perpetual inventory approach all that is needed is accurate on-hand positions and replenishment points for all inventory items. On-hand accuracy can be accomplished through a full physical count completed by pharmacy staff or an outside party. Establishment of replenishment points can be handled by pharmacy staff or through automation via inventory management software. With on-hands accurate and replenishment points established, restocking will occur when on-hand position reach or fall below the re-order points.
Perpetual is clearly the best solution and provides the following benefits:
- On-Hand inventory is always accurate
- Financial conditions (inventory investment and profitability) are readily available
- Theft/fraud/diversion—shrink is easy to spot when PMS and shelf disagree
- Free up working capital / improve cash flow
- Choice of manual or automatic EDI ordering
With on-hand accuracy established and maintained and re-order points in place within the PMS daily ordering can accomplished in two ways. Using the purchase order available through the PMS staff can place their orders on a manual basis or, for great efficiency and time savings pharmacy staff can use automatic Electronic Data Interchange Ordering (EDI).
While the benefits of the Perpetual Method are clear and substantial, without automation, it does come with inherent problems. Maintaining reorder points for thousands of drugs, while recognizing fluctuating demand, is nearly impossible without the proper pharmacy inventory management technology.
Benefits of Automation
- Monthly re-order point optimization—always in lockstep with changing demand and the preferences of management/owners
- Automatic return and transfer recommendations
- Improved fill-rates and inventory turns
- Intelligent cycle counting
- Data analysis allows a close study of purchasing trends
- Reduced ordering time—more time for your patients
