The most exciting aspect about this software has been its ability for companies like mine that rely heavily upon client satisfaction as well have our clients trust us with their finances! It's not so much any thing I dislike but more just how new it still seems especially when compared in comparison against other payment processors such are PayPal or Stripe.
We've had nothing negative experience while using Tiffy thus far we do receive many requests requesting feedback through email etc yet again no issues at all!
