So far so good thou I only used it to print out claims I do like the features it has. I should be upgrading my account in the next couple of months if all goes well.

Pretty good so far. Was a little surprised that I had to pay once all the work was done. But its okay, have used it a couple of times and its working.

the service is great, however the payment option is miss leading, as it says $6/month and when you go to pay you charge the full year up front, in US$ and some of us are poor, so thanks for that.

What do you like best?
No more printing and filling out forms by hand.
What do you dislike?
I used to be able to upload a signature from an iPhone photo, and it could be placed on a document in a way that it look like it was written there, and not a pasted photo. I liked this and cannot seem to do this anymore.
What problems are you solving with the product? What benefits have you realized?
It's amazing how many forms still need to be filled out by hand in this age of tech and no typewriters. Printing documents, hand writing, then rescanning to a recipient is messy, time consuming and wastes ink and paper. Besides, make a mistake, and you need to start over with a new form. And don't get me started with "white out." PDFiller streamlines all this and results in a very neat, professional looking document. I do lots of contracts, and don't always get red-line drafts to work with. I can use PDFiller do do red-lining (word-processing changes to early drafts) and send them right back to the counter-parts. Then with the final draft the PDFiller signature feature allows me to initial or sign, and send - again without printing/rescanning. Since for many transactions e-transmitted signatures, as opposed to "wet" signatures, has become standard and legally acceptable the process is now a breeze. And if I still have to go back for further revisions the prior versions are all saved in PDFiller.

Helpful program with good customer support This program makes it much easier to complete a complex form than doing it by hand and the customer support is very responsive.

What do you like best? With a lower monthly fee, I can log in and have the capability to use the editing tools to update and sign my files with ease What do you dislike? I do wish that notification would go out to my email if or when the website is updating the platform What problems are you solving with the product? What benefits have you realized? With any update that has adjusted the layout, I have been able to get ahold of customer service for clarification. Although the 24hrs wait for a response is frustrating

I am a ******* Home Inspector and love PDFiller. I can do everything on my IPhone. I had a problem at first and had an online chat with ***, helped me fix a problem on a 4 point inspection and had it corrected in 15 mins. Once you learn your way around PDFiller it can save you lots of time.

It makes creating and sharing most document types easy. You can also create just one PDF to replace multiple documents of different formats. The Portable Document Format is ideal for basic presentations and easy-to-read reports.
