I have client portals on my website, but sometimes the clients can’t remember their passwords to get in there!  I just wanted to tell you – I have used Verifyle twice this week to send tax return copies and a copy of their extension to two clients.  It was very easy, and the feedback that I got from them was that it was very easy on their end too!

As I was reading the announcement about VeriFyle, I started wondering "What's the catch?" and "What are they gonna try to sell me?".  All those thoughts completely disappeared when I saw your signature. Your reputation and interfacing with you these past couple years have garnered my complete trust and faith in you.   Thank you for being proactive and bringing this benefit to CSTC members.
