Per-transaction fee
A fixed amount charged on each transaction regardless of its size, usually quoted alongside a percentage. Its weight depends entirely on the average ticket: negligible on a large sale, and frequently the majority of what a merchant pays on a small one. It is the number a small-basket merchant should focus on, and the one a headline percentage hides.
Why it matters to a merchant
The component that decides everything for a small basket and almost nothing for a large one. At a two-dollar average sale a fixed fee can exceed the percentage entirely, which is why the right provider for a convenience store and the right provider for a jeweller are frequently not the same company.
