ive pretty much boiled down my choices to square or paypal pro. square pros: i like square because there is no monthly fee and smaller percent however i do have to pay one time $85 for an extension to integrate it into magento (unless i am missing something here) its a trusted and overall great system 2.75% square cons: does not take paypal as payment method pp pro pros: takes all forms of payment, including paypal pp pro cons: $30 a month 2.9% both services offer relatively the same thing with mobile card reads etc. does anyone else want to weigh in? has paypal ever deterred someone from buying over square? my thought was to do square and then offer paypal express option on the site but now i am managing two different places.
