2. Accounting for goods: The system must take into account the goods that are in stock in the warehouse. There should be information about the goods that are in transit, indicating the estimated delivery time. Tracking lost orders due to lack of goods in stock (for this you will need to implement a button in the product card so that the manager can click on it when a request is received and the product is out of stock. Also, so that the system asks the manager for the quantity of the product. Which the client needed)
3. Delivery times are approximately the same for all products, so they will be averaged for ease of calculation.

5. Reports and analytics: The ability to generate reports on the availability of goods, expected deliveries, missed orders and sales dynamics, stale goods (which have been in the warehouse for a long time and are rarely sold or not sold at all)
Analysis of order effectiveness and optimization proposals. Technical requirements:
