So surprised and happy to find this VA…
So surprised and happy to find this VA application online and available to convert to a filler style form. Printing the document by-hand was painful and re-dos were tedious but with your program I was able to complete and annotate (where needed) the application in a legible, presentable manner. Thank you for this program.
That i was able to fix and remove…
That i was able to fix and remove unwanted documents to send just what i needed. The fact that I can fax without having a big machine to do, matter of fact that is one of the reasons that I decided to use pdfFiller. You make filling out important documents easy and able to sign by uploading just a picture of the signature needed. However you could make it easier to be able to create a fax sheet more personal. The one on the website is okay but not personal enough. Maybe I will think about doing the annual thing let's just see what more I can learn to do with your program. thank you for making it so easy to send important documents from the comfort of my home office without having to pay someone else to fax for me
What I really like about the program is…
What I really like about the program is that we have a lot of issues and it was able to handle them all! My husband plays music at church which is a standard business. He is opening an LLC which we need to do several forms which most places do not handle including the 1120s, the k1, and so many others. The pdfFiller has handled them all!
Editable Template
I needed a template to create a one pager for a project and pdf filler was perfect for editing the document. I could even add pictures.
