Understanding how billing line items are categorized, the term that signals a row is a correction to charges billed in a prior period is the charge class. Charge class serves as a category for the nature of the charge, so a correction or credit on an earlier invoice can be tagged with a specific charge class that marks it as an adjustment rather than a new consumption charge. This separation is important for accurate reporting and reconciliations, letting you see what portion of an invoice came from normal usage versus corrections to earlier bills. The other terms describe what the line item contains—Costs is the monetary amount, Usage is the quantity consumed, and Charge description is the textual label of the item—none of these inherently indicate that the entry is an adjustment to a previous period.
