Transaction fees are usually the biggest cost over time
Monthly fees – as some providers charge for accounts or terminals
Hidden fees – you need PCI compliance, authorisation, chargebacks
Contract terms as longer contracts often reduce costs
Your volume for higher turnover as this unlocks better pricing
