What type of items would benefit from a description stating "should be positive" in a daily sales summary?

In a daily sales summary, stating that an item "should be positive" is particularly relevant for sales items. This is because sales items pertain to products or services that are being sold to customers and are expected to contribute positively to revenue. The term "positive" in this context typically indicates that the sales figures should reflect income generated from those sales, as opposed to losses or returns.

When summarizing daily sales, a positive figure for sales items signifies successful transactions that lead to financial gain for the business. It emphasizes the importance of tracking sales effectively to ensure that the business is operating profitably. In contrast, service items, inventory items, and discount items might not have the same direct correlation to positive sales figures, as they could represent costs, stock that hasn't sold, or reductions in revenue, respectively. Thus, sales items are the most appropriate category for expressing the need for a positive description in a sales summary.
