im just learning with a new business i just started. i love it. I dont have a printer or scanner so i really appreciate you guys for offering the services you do through PDF.
keisha m
I use it for filling out work related forms. The forms look much better when filled out online rather than writing in all of the data. I'm able to save a copy online or on my computer, rather than filing a hard copy. It's very convenient and the forms look good too.
Chuck S
The service produces a very handsome document, and facilitates changes when necessary. I had a little trouble navigating back and forth between the document and the print function, but that may be attributable to my lack of familiarity with the product.

5* Customer Service I am very impressed with the customer service. When I was charged for a years subscription after my free trial, which I queried immediately, I received a full refund within the hour with no quibble.
Mrs. Sue Burton
I mislead them on my intentions for the service level that I required. Once I brought it to their attention, I answered 3 questions; and the matter was immediately resolved. Outstanding customer service comms. !!!

I gave a bad review initially I gave a bad review initially. I didn’t get the help I needed. Immediately someone else reached out. My issue was resolved within a few hours. I’m happy with the help I got the second time around. Thank you Gerald!
