A strong inventory management software can be highly beneficial in this situation. This software allows for the efficient management of all monitor models, even without using serial number tracking. We can sort the monitors into various categories such as "in stock," "deployed," "in maintenance," and so on, according to their status. This approach ensures that all monitor models, whether old or new, are accurately tracked. Additionally, we can implement an automated alert system within the software to notify us when the quantity of a specific monitor model falls below a set threshold. This helps us prevent overstocking any model and facilitates a seamless transition from older models to newer ones, ensuring we do not run out of inventory. The software can also aid in effectively redistributing the older models across different depots.
