Peter Germanov,
Principal at NowCerts
We were previously using an all-paper hiring and on-boarding method. We switched all those documents over to Sign Now, and our whole process is so much easier and smoother. We have 7 terminals in 3 states so being all-paper was cumbersome and, frankly, silly.
Kodi-Marie Evans,
Director of NetSuite Operations at Xerox
«signNow provides us with the flexibility needed to get the right signatures on the right documents, in the right formats, based on our integration with NetSuite. This flexibility assists us with reducing our turnaround time on signatures so that we can get to the business of doing business. signNow is an amazing company with first-rate customer service.»
Jake Schroeder,
Vice President at The Benefits Store
«We found signNow to be better priced and exactly the solution we needed. signNow has significantly lowered our enrollment completion process by a day or two depending on the member.»
Dionte' Bryant,
Software Development Engineer
«The signature has become extremely simple to create. Customer care is additionally quite simple and also incorporating fields is super easy. We put it to use for all sorts of contracts. Custom contracts can be simple to operate, but we primarily work with them to send out the very same agreement template to almost all the clients of ours.»
