Exactly what I was needing for my real estate business to take it mobile. Nothing else is exactly like it - none of the "signing" apps quite cut it. Thanks, PDF Filler!

Everything has been great, with the exception that it takes a while to open up the documents on mybox. There should be a feature for ''QUICKVIEW" of the document you want to open.

prepare your base document, and save. then save as onto your computer desktop, and rename once downloaded onto your computer desktop. reuse the base document over and over for different clients.... works great and gave me the exact form i was looking for.

I love it but when I was trying to edit document I could only click and erase some fields. I had to use the eraser for the rest. But overall great product.
2018-11-27
works, got my document, little squirrely on fill in but I figured it. It takes about 75% more time to fill in, not a seamless experience. If the typing could be done with out having to locate start character, would hlep

PDF Filler is a wonderful application…
PDF Filler is a wonderful application for downloading common PDF forms (was really a boon during the recent tax season!). You can fill out the PDF forms electronically, save, and do whatever you need to with them- such as printing, sharing, etc. I love it!

I've used this software before, but I find Pdf Filler a bit better for my use. I need to learn the software better, because if it continues to help in my work I will be a loyal client.

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.

The format is easy to understand and quite intuitive. Very quick loading times. My only problem is that text boxes do not align correctly to the pdf that I am editing - they are too high.
