Peter Germanov,
 Principal at NowCerts

We were previously using an all-paper hiring and on-boarding method. We switched all those documents over to airSlate SignNow, 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.

«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.»
