Managing stocks is an essential aspect of any business that deals with physical products. It involves keeping track of inventory levels, ensuring that there is enough stock to meet customer demand, and minimizing the risk of overstocking. One way to manage stocks effectively is by using a system that allows authenticated staff to add and remove stocks as needed. This ensures that only authorized personnel can make changes to the inventory, reducing the risk of errors or theft. Additionally, giving each product a unique barcode with a Global Trade Item Number (GTIN) can help streamline the process of tracking inventory levels and identifying specific products. By implementing these measures, businesses can improve their stock management processes and ensure that they have the right products available at the right time.
