Transaction fee

A fee charged per transaction by the gateway, processor or acquirer.

Plain-English definition

A transaction fee is a per-transaction charge applied by the gateway, processor or acquirer, usually in addition to percentage-based interchange and scheme fees. Some providers bundle their margin into the percentage rate; others split it out as a flat per-transaction amount. On low-value, high-frequency travel payments the per-transaction component can be a meaningful share of total cost.

Why it matters in travel

Travel businesses with high volumes of low-value bookings — ancillaries, day tours, small balances — are particularly sensitive to per-transaction fees. The effective rate on a £50 ancillary looks very different to the effective rate on a £5,000 booking.

For a tour operator selling £40 day-trip ancillaries alongside £4,000 itineraries, the per-transaction fee can flip the economics on the small end while being invisible on the large end. Across an ancillary catalogue with millions of transactions a year, a per-transaction fee a few pence wrong is real money — and most travel businesses never break it out by product.

The travel businesses that watch transaction fees at product level price ancillaries deliberately, choose acquirers that suit the small-ticket mix, and negotiate per-transaction components separately from percentage rate. The businesses that treat fees as a single line item subsidise their small-ticket products with margin from their large-ticket ones.
