The search option brought up the forms I needed. In on instance multiple versions were on different sites. I was able to bring in to the appropriate version by typing in the URL, I found that to be a real time saver.
William E. B
So far so good. Was very helpful in completing government report on non-fillable .pdf document. That was the original purchase purpose. Now trying out modification / repair of existing fillable forms.
Al A
The best part is that it automatically "carbon copies" to other pages if they require the same information (ex: 1099 tax doc). I've used other PDF generating programs and you have to manually fill in each page. This is such a time-saver and seems like an obvious feature that would be part of any PDF program. I guess this is what makes PDFfiller a greater product than the competition!
Gena
Great editor, Could have some more funcationality but does 90% of what I want to do. Previously purchased another program (Soda PDF) and couldn't get my head around it. PDFfiller is soo much easier to use, with heaps of online help on how to do anything you want to do.

What do you like best?
I love the ability to make my own PDF Templates. It is the perfect insurance agent tool when you're doing multiple certificates of insurance for commercial customers during renewal time. I love the feature where I can e-sign the documents and save it as a PDF which saves me ink and paper.
What do you dislike?
I can't figure out how to combine 2 PDF'S and merge them together so I use a different program for that.
Recommendations to others considering the product:
A must have if you're in the insurance industry
What problems are you solving with the product? What benefits have you realized?
It saves us time by creating templates, super helpful when it comes to creating multiple PDF's for our customers.
MARIA ALTMAN
What do you like best? Easy to navigate the dashboard,easy to click on and move text items in documents. What do you dislike? The text type doesn't always match the font of the document I'm filling What problems are you solving with the product? What benefits have you realized? Quickly filling out forms and adding electronic signature.

Fumbling along with Adobe Acrobat or hand-writing forms was time-consuming, sloppy, and completely inefficient—especially if changes or updates were needed. We are going to continue to use pdfFiller and find additional uses for the product as our business grows.

pdfFiller saves us $100 or more each workday when you factor in employee time and supplies. The figure is probably higher than that, since the waiting time for patients not yet seen is also diminished, which keeps the patient from being frustrated and just leaving before their visit.

Pro Tip: Always verify a platform’s compliance with industry standards, particularly if your organization deals with sensitive information.

Pro Tip: Before committing, assess not only the initial cost but also the long-term benefits of each solution to ensure sustainable value.
