Compayr may earn a referral fee when a merchant switches via our links. This never affects rankings, which are based purely on lowest card processing costs. Quote-only providers are never ranked as cheapest while a complete-cost option exists. Rates last verified 2026-09-03. Confirm current pricing with Square. We compare one standard published plan per provider; promotional and individually negotiated rates are excluded. Some providers pay Compayr a referral fee if you switch through our link; this never affects our comparison, which is ordered purely on lowest estimated card acceptance cost.
