I have been talking with a lot of CPAs the past few months and I really am amazed how few offer portals, eSignatures, etc. The survey results back up what I have been observing. I guess since I am younger, I thought far more firms offered this technology that I have been using for years.
The most difficult to onboard with technology are older people, but they all have cell phones and can generally text. If they can do that, they can certainly figure out using a simple mobile app and their phones to "scan" documents, sign engagement letters and eFile forms, etc.
