How we compare
Comparisons are built by desk research from each provider's published rates, upfront costs, contract lengths and settlement terms, held in a dated record per terminal. We do not test devices ourselves; specs are taken from provider documentation and cited. MerchantHQ is an introducer. No provider pays for inclusion or position, and fees never affect how we compare.
