I AM ONLY HALF WAY DONE BUT SO FAR VERY EASY,HOWEVER I FIND THE BILLING OPTIONS DECEPTIVE, ALSO LIVE CHAT SUGGESTED A SOLUTION BUT DIDN'T MENTION IT REQUIRED AN UPGRADE!

The learning curve is fairly easy and short. Still learning features as I go. I use the program every two weeks and generate four documents each time. I've been able to look up every document that I have needed and able to open and edit and print. There are occasions that he document will cut off part of the header or will not allign the text correctly. However, that's about 3% (or less) of the time.

PDF Filler is great. I started with the free trial, then went to the pro, but now I've switched to Basic. I got this for signing contracts on buying and selling my home. Awesome!

This is an absolutely AMAZING service This is an absolutely AMAZING service, the only reason I had to give 4 stars instead of 5 is due to the cost. To expect people to pay so much money (especially during the pandemic) when everyone needs to work and operate from home is unconscionable. If this service was, say, $12.99/mo. then I would most definitely pay it. However, the monthly cost is nearly three times that high, and it is not something I can afford on unemployment benefits of $235 per week. This service is amazing and efficient, but the company is not being realistic about the current cost of its services. And no, offering annual payments of $200+ is not a viable solution.

This is the most amazing app This is the most amazing app, it really is a great one-stop portal for all my practice needs, and it is SIMPLE to use, even for solo practitioners like me who don’t have an IT department.

I really like the service a lot. It is user friendly and intuitive. I like that this also comes with Sign Now so that I can have all the forms I need for my business easy and accessible for me to get electronically signed. I would give it 5 starts except in the Sign Now program the program should default to the text box for people to sign and then have the live signature be on a separate tab, so basically reverse what it is now. It is hard for some people to get to the text box for them to type their signature. I use this all the time in my business and I would recommend it.
