Unlike Paypal and Square Up, PaySimple is more of a full merchant service and less for a guy getting paid for moving a couch. But it does have a mobile credit card swiping app, just like other services these days.
As for their fees, it is 2.39% + $0.29 per transaction, with a $34.95 / month fee. ACH, or electronic wire transfer is $0.55 per transaction. Interesting that they charge for ACH when banks usually don’t charge for that.
Backed by HSBC Bank, this service will be around for a while.
