Interchange-plus
A pricing shape that quotes the acquirer’s margin separately from the pass-through cost, so a statement shows what went to the issuer and the scheme and what went to the provider. Harder to read than a blended rate, and the only shape that lets a merchant tell whether a change in cost came from their provider or from their own customers.
Why it matters to a merchant
More lines on the statement and more information in them: the merchant can see the floor and the margin separately, which makes the cost of a change in mix visible instead of invisible. The trade is admin, and whether it is worth paying depends on whether anyone will actually read the detail.
