With this product we can send out any forms that we need our employees to complete without having them come into the office to complete. This saves everyone time and money with just a click of a button. Our employees love it even the ones who are not so tech friendly.

I love that I am able to send and review all documents that go out to our employees. We are bale to set up multiple documents and either send them out separately or in a group email.
