A nice format that allows a professional presentation but the data input is still tedious and could be streamlined. All things considered, I'm satisfied with the product.

We love how easy this system is to use for all of our real estate transaction documents. Very easy to navigate on a PC / MAC on a great app for your phone!

I find using the system helps me integrate school documents for my children. It is a great addition to anyone who owns a business and is looking for a nice way to conduct business at home or on the go! I highly recommend the app to anyone and find it very helpful. Definitely put the app on your mobile device! It work fantastic!

What do you like best?
I use Quickbooks and have to send out 1099NT which is not a capability in Quickbooks. 1099 forms must be scannable and I can purchase the printed forms and fill it out on PDFfiller. I can then print on the scannable forms and they are perfectly aligned. Saves time and money. Also, I like the fact that I can create a template so I don't have to re-type the same company information, tax numbers, etc. The product is easy to use.
What do you dislike?
I don't really dislike anything about PDFfiller. Other than maybe the fact that I probably don't use it enough to offset the cost.
Recommendations to others considering the product:
Easy to use - I intended to use for a month and then cancel, but I ended up keeping it.
What problems are you solving with the product? What benefits have you realized?
I mostly use for 1099NT's as mentioned above. I really need to explore!

Overall a great product
Overall very easy to use, tools are easy to manage and it's great at converting PDF to Word.
It is a little expensive but other than that, no issues.

I used this PDFfiller for the 1st time and it worked great. I was able to drag the document that was sent to me into the PDF filler and it opened all the fields so I could edit and resend.

Not very user friendly
Not very user friendly. The "sign-up" commitment is not good... Inevitably some people will forget to cancel and then will be hit with a high annual charge...

I signed up to help with a real estate contract. I was able to complete the form and email the document. It took me a little while to figure it all out but once I did it went smoothly.

Ny experience was good but I only have a need for the form I used maybe once a year. So I will probably be canceling my month to month once I am sure the form I needed has been accepted. It would be nice if you had an option for a subscription that was based on usage rather than on time. I might then sign up for a longer term commitment if I wasn't being charged every month but rather on my usage. My experience with your product was that actually filling out the form was user friendly but it was a form that had a continuation sheet and figuring out how to use several continuation sheets was not intuitive and I ended up filling out several different form continuation sheet pages and then had to combine all those multiple forms into one document in order to get what I needed for submission to the court.
