I complete 1099Misc for my office annually. I just discovered your site which is handy as far as anticipated amending and last minute entries. I am having trouble with the How To's of IRS submitting and multiple entries.

Following my previous comment, I found the tax forms I was working on, but they were titled by the Form, not saved documents. Taking me well over an hour due to the labeling. Need a Saved Documents Option to simplify it.

Have been using for 1-2 years. Easy to use, and the functionality continues to improve. A bit more costly than other options, but the convenience is well worth it.

I like how easy it is to edit the content of a PDF. I've recently had to adjust a few documents which were not previously editable for me, and this has made it simple to keep things updated.
What do you dislike?
I would like to be able to choose the file destination when selecting Save As, rather than it defaulting to my Downloads folder.
What problems are you solving with the product? What benefits have you realized?
We've recently implemented new contracts for our accounts, and using PDFfiller has made creating them so easy. It's saved me a significant amount of time.

PDFfiller Review
Great and easy way to make sure your PDFs are signed, sealed, and delivered as quick as possible.
As a contract administrator for my company, this makes signing PDFs easy, and allows it to be done in a timely manner. Easy to navigate, allows you to download your finished, signed PDF for storage.
Takes a little bit of time to learn the advanced functions, and a variety of color coding features who make highlighting PDFs more efficient when needed/if multiple people are adding notes.

Very useful tool
Useful app for managing all your pdf tasks. I always use this app to sign. Very recommended.
It doesn't have many free features, you have to pay for the good ones.
