I help my cousin run a Magento 2 store for their seasonal gift shop, and we used to struggle with either overstocking or running out of the most popular items during peak times. One year, we got some advice from refinedcommerce.com, and it seriously turned things around. They suggested using a mix of predictive analytics and inventory management tools, plus we added a promotion scheduler extension.Now, we plan promotions ahead of time and sync stock levels with expected demand. For example, last holiday season, we used data from previous years to bundle slow movers with hot sellers, which helped balance inventory.
