What does buffer sales mean in the context of the "show calculations" feature?

In the context of the "show calculations" feature, buffer sales refers to the estimated sales between the order cut-off day and delivery day. This concept is crucial for inventory management and demand forecasting. By estimating these sales, businesses can ensure that they have sufficient stock to meet customer needs during the time when new orders are not being placed yet, thus avoiding stockouts and ensuring a seamless supply chain process. This calculation helps in planning and preparing inventory levels effectively based on projected sales fluctuations during the buffer period.

The other options do not capture the specific definition of buffer sales accurately. Extra stock in the warehouse relates to inventory levels rather than estimated sales dynamics. Sales generated during a promotion captures a different aspect of sales activity focused on specific campaigns. Finally, all sales recorded in a month provides a broader overview that doesn't highlight the specific timing associated with the cut-off and delivery days relevant to buffer sales.
