Great product for my home-based business. No more searching online for forms or templates and cutting/pasting the old fashioned way! Easy to use and all of the documents my business uses.

I used the service like the service, but until I got to print a copy of the SR-1 form, I thought I was using the government's free website for submitting an SR-1 form. I want to cancel it because I will not need to use it again. So, please cancel my account and service. Please also send an email to me confirming that you have cancelled the service. Thank you.

i love the user experience but it is a little difficult to tell where the writing will show up on the lines once I save to PDF and send to clients. also, if the lines are close together it is hard to tell if your letters will get cut off. but overall its a great product going to try to use online and see how that works.

I wish there was a way to access a blank 2019 W-2 form. The first form came up as 2019, but the only way I found to create 2019 for the other employees was to duplicate that first one and modify for the additional person. If not for that quirk, I would have given 5 stars.

What do you like best?
This just helps a ton when I need to edit a pdf on my computer. I used to export PDFs as a jpeg and edited the photo and it was super stupid but this is perfect because I never have to try to remember how I edited a PDF the last time I did it.
What do you dislike?
It’s a little clumsy and took a bit for me to figure it out, which means I’m not excellent at explaining how to use it to other people that aren’t technologically inclined, but it still works really well.
What problems are you solving with the product? What benefits have you realized?
I need to edit release forms and vouchers on a daily basis for my models and it’s a breeze with this extension on my laptop.

Great service that has a lot to offer besides editing pdf files. Love this and it has been well worth the money.

Easy to use
It has made life much easier for my clients to receive what they need in a more timely manner
Easy to upload specific documents for editing.
When a field needs to be erased, the program always resets to add text. You have to re-select the erase button after each erased field.

As a freelancer I use PDF Filler to complete W9 forms - it's great!
PDF Filler is simple, easy to use, and creates professional documents that are easily accepted by employers and large corporations.
The exporting workflow is a little confusing - at least for their IRS W9 Form. Instead of just pressing a button to save the file to my phone I had to email it to myself in order to obtain it. This may have just been my ignorance, however. All in all, PDF Filler is a great help!
