updateStock

updateStock is a function commonly found in inventory management systems and e-commerce platforms. Its primary purpose is to adjust the quantity of a specific item in stock. When an item is sold, the updateStock function decrements its current quantity by the number of units sold. Conversely, when new inventory arrives, the function increments the stock level by the quantity received.

The updateStock function typically requires at least two parameters: an identifier for the product (such as a SKU or product ID) and the quantity to be added or removed. Some implementations might also include parameters for tracking stock movements, such as the reason for the change (e.g., sale, return, damage, receipt) or a timestamp of the update.

Accurate stock management is crucial for businesses to prevent overselling, identify low stock levels, and maintain efficient operations. The updateStock function plays a vital role in ensuring that the recorded inventory levels accurately reflect the physical stock. Errors in this function can lead to discrepancies, stockouts, or excess inventory, impacting customer satisfaction and profitability.
