Program is a time saver for me.
Plus my reports have a more professional appearance.
I would not want to go back to doing it the old way.
Thank you PDFfiller!

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!

Awesome!! I don't know what I have done without you. I do real estate transactions weekly and I love that I can upload different documents, edit them, and send them out. Well worth the cost. Thank you.

IRS changed the 1099 misc form
IRS changed the 1099 misc form, so I had to find an alternative access to the 1099 misc form that showed non employee compensation. The 1099 NEC form was the form I needed. A new bokkeeper will handlethis from now on. Thank you
2023-02-04
Have used it to fill out two forms and was very pleased with the experience. The only problem I encountered was being unable to expand the circle. May be due to my not fully understanding the program's capabilities.

What do you like best?
It is much easier to use than Adobe Acrobat. Much more intuitive functions and file management. It has saved me a ton of time with the cloud storage of documents. I have used effectively for construction related documents.
What do you dislike?
Very rarely I have needed to use another platform because some municipalities require it but 98% of what I need to do is supported.
What problems are you solving with the product? What benefits have you realized?
Remote completion of forms and extracting text from PDF documents mostly.
