After being turned off by the original warning about not being able to submit the forms to the government, which I think is CONFUSING, I kept digging in and found that once you pay they are acceptable. Now LOVE IT

Will only be using it up to the end of August as I'm doing a course at the moment. Very happy with it and if I need to use it again I will sign up...

Happy with PDFfiller!
PDFfiller makes the documents that individuals within my company need to use frequently, more readily available, an improved option to frequently having to make copies before working with clients.
I really appreciate the functionality and ease of use for the product. The fact that it is possible to create a fillable PDF, to be used by multiple people or times. Uploading documents is extremely easy and the layout on the website makes all features easy to find. My absolute favorite thing is that you can sign things by singing from your phone, or saving a signature that you already have saved.
My only frustration is that if you download a fillable PDF, even when saving it will a different name, you can't print it with the content. I have found that I have to import the document and then print directly from the website, yet when uploaded the document makes the typed font smaller. Another tricky thing is that if you want to create a fillable PDF you must meticulously go through the document to check and highlight anything that you want to be able to fill information.

What do you like best?
Being able to fill in documents that were previously not fillable. Being able to file some tax documents through pdfFiller has been great also.
What do you dislike?
I haven't had any problems at all with pdfFiller
What problems is the product solving and how is that benefiting you?
Filling out documents by hand did not look professional. Transferring the documents to pdfFiller & typing in the information is much better.

What is a Required Field?
The term Required means the fields are obligatory for filling out. If they are not filled out or the user typed in data only partially, the Complete button will not work. The filer will see a notification about the necessity to fill the fixed number of empty fields.
Those fields will usually be highlighted with a dark color. A yellow flag helps you find the required cell. The fields highlighted with a lighter color are optional.
The Guide Me instructions are available to those who have difficulties with defining the type of needed field.
