How much inventory do I need for Black Friday?

As an e-commerce business owner preparing for Black Friday, I'm struggling to determine the right inventory levels to maximize sales without risking overstocking or stockouts. I need a strategic approach to forecasting demand, understanding historical sales patterns, and ensuring I have enough products to capitalize on this critical shopping day without tying up too much capital in excess inventory. What factors should I consider when calculating my Black Friday inventory requirements?
