The experience was interesting. I would recommend the company to others but I would make sure that the price is up front before purchase is made. I misunderstood the price of the product. But Again I would recommend the company just for the fact that they are very helpful.

Form 1099-misc accepted the data that I entered in each filed, and propagated it to all the required Copies; then prompted me to Submit to the IRS ... This simplifies my execution of Federally mandated processes ... Thank you very much! Also, support staff is very responsive! Thank you!

What do you like best?
I love the ability to make my own PDF Templates. It is the perfect insurance agent tool when you're doing multiple certificates of insurance for commercial customers during renewal time. I love the feature where I can e-sign the documents and save it as a PDF which saves me ink and paper.
What do you dislike?
I can't figure out how to combine 2 PDF'S and merge them together so I use a different program for that.
Recommendations to others considering the product:
A must have if you're in the insurance industry
What problems are you solving with the product? What benefits have you realized?
It saves us time by creating templates, super helpful when it comes to creating multiple PDF's for our customers.

There should not be an option for… There should not be an option for alteration on the PDF document. For example, when I tried to type my name, I made a mistake and I back space the mistake but I ended up deleting the line on the original PDF document. A program like this should not give me the option to do that. Other than that, I felt like PDF Filer got the job done for me.

What do you like best? The features and tools of PDF filler editor are really perfect. I can describe it as a strongest online PDF editor in comparison with another services. With this service you dont need any expensive PDF editor softwares like Adobe Acrobat on your own system. What do you dislike? Some fonts and non-Latin languages not supported. What problems are you solving with the product? What benefits have you realized? I have used it for filling official forms and I am satisfied.
