Changing the amount of an already-authorised transaction before the batch closes, to add a gratuity written on a docket after the card was presented. It is a restaurant workflow rather than a general one, it is bounded by the batch cut-off, and whether it is available depends on the terminal and the account setup rather than on the card.

## Why it matters to a merchant

A workflow question that decides whether a restaurant's evening reconciles cleanly, and one worth confirming for your own setup rather than assuming from how a previous job worked. The constraint that catches people is the batch cut-off: an adjustment attempted after it is not an adjustment, it is a second transaction, with everything that means for the customer's statement.
