I had to cancel my subscription right after I got it (the first time) because we were told not electronic signatures. The customer service person I was connected to was very quick with applying my refund and explained the banks general policies. It ended up there was a mistake, so I'm back. I enjoyed the ease of using the product. I was able to pretty much teach myself how to use it. I do look forward to seeing what the webinar has to offer.

great I run a water and sewage restoration business and this had made it possible to do all my emails and bids in the field. This program has made me thousands of dollars. As a business owner with no computer traning and self taught to pick at a keyboard. I now can compete with the business who run 5 employees doing paperwork and emails. This allows me to do the work of 4.

I love this tool
I love this tool. I shared it with my mom who still has to fax things and I did not want her leaving her home to fax at other businesses. I think a video on how to create more fillable boxes would be helpful. Although I figured it out, it took me about 30 minutes. I can imagine for even less tech savvy people it could take longer.

Easy to use
Easy to use. Has an issue with locating my document on my device when done. Took a few minutes to find it in downloads instead of documents.

It's been great so far. I need to learn how to move around the dashboard quicker. Also, I need to learn how to set up individual folders (if applicable)?

There are some minor things I have not figured out how to do. Not sure yet if they are just missing features, or just not readily available in a way that I was expecting.
