Randy A. K

What do you like best?

I'm a small CPA firm and require signatures on engagement letters and confidential tax documents. I've tried other solutions but some of my clients found the other solutions a bit clumsy. I've received very positive feedback once I switched to airSlate SignNow. I also really appreciate the option to choose 'do not send signed documents' for confidential information. It's a great choice for CPAs, Attorneys and anyone else needing a secure yet easy-to-use solution. It's also IRS compliant.
