Wish that the tools were better on the app. Very limited there.
Also that there was a square/box that could be drawn, not just the addition of a circle.

I needed to fill out a one-off 6 page form and was looking for a free app to do it. When I Googled for this you came up and I did not track it was not free until I completed the form. Then I was "stuck" b/c I needed it asap and the request for payment did not come up until the end. I was not happy and would never have used the program had I tracked what happened. That being said, it was an excellent program and if I had to fill out forms routinely, I would recommend it. But since I don't need this app, please cancel my subscription.

In general its an effective tool. I don't like that it will NOT allow you to leave spaces (eg. 1.5/2.0) spaces been typed words. So everthing looks to compact and scrunched in - definatelt a flaw!

easiest way to fill forms!
I like it and I recommend it to anyone who works with Forms that cannot be edited using another softwares.
In my job we need to complete a LOT of forms (we are a law firm specialized in tax and corporate law so we need to complete a lot of forms that come in PDF format) and some of them doesn´t allow us to make any edit in the regular PDF program so PDFFiller is our salvation. It is super easy to use and it allows you to edit the entire document using only this software. You can add text or even delete parts that you don´t need. It is a software that doesn´t require any effort to understand because everything is as simple as upload the document, make the changes and save as pdf or print the document. I use it every day and I find it very complete for the things that I need.
You are not able to use it in several computers, so if by mistake you open your session on another computer you may loose your work.

What do you like best?
I love that I can fax items as well as the W-2/1099 features that are integrated into the IRS system! It makes my roles as a small business owner much easier with these tools.
What do you dislike?
I wish more features, such as sending documents for signatures, were added. Even just 1-2 documents a month would be helpful for my small business. A fax number included would also be helpful. I have been able to get a fax number for virtual faxing for much cheaper elsewhere. It would be nice to have an all in one for less than $25 a month or so.
Recommendations to others considering the product:
Great way to keep costs low while still running with the bigger companies and their larger budgets. From creating my own documents to faxing things for clients- great investment for virtual tools in your business!
What problems are you solving with the product? What benefits have you realized?
The IRS integration have helped me navigate some of the tax paperwork I need to do for my employees. The fax feature is super helpful for getting paperwork out for our clients.

What do you like best?
I love that you can store your signature in the program. Also much more professional look over using a pen to fill forms.
What do you dislike?
The extra level of security when logging in slows you down a little. Its probably actually a good thing as your forms are stored in the system
Recommendations to others considering the product:
I have tried to figure out ways to fill pdfs without signing on to this system, it was a foolish waste of time. I am not the type of person that signs on to programs like this, I always felt like they were scams. I am so very happy with this program, I wish that I had signed up for this much sooner. I am not even using all of the features of this program and Its totally worth every cent!
What problems are you solving with the product? What benefits have you realized?
When companies email me a form that needs to be filled out and returned, pdfFiller makes it so much quicker, easier and more professional
2021-02-28
What do you like best?
The ability to login anywhere and get work done while I am in the field
What do you dislike?
I don’t use it every day so sometimes I need the help menu to navigate new documents
What problems are you solving with the product? What benefits have you realized?
The ability to work in the field without carrying a laptop. I can sign documents and send them securely. This mobility allows me the ability to do more work.
