2 things I would like to see changed. The original custom color selector was better than the these presets that are available now. The other is the sizes of the font jump by twos, an input to put in a custom font size would be great

After contacting customer support, I was told that certain web browsers are more compatible than others in completing forms. Once I changed from Mozilla Firefox to Chrome, I was able to complete all fields of the form without problems. But it would have been helpful to publicize this information on your website so that much time was not wasted.

What do you like best?
I enjoy the way PDF is easy to use and allows us to send out documents quickly. We operate a few different locations remotely and we are able to send out important documents require signatures in less than 5 minutes! Support is great when needed but we seldom have any issues.
What do you dislike?
There are not many issues with it. It would be nice to be able to copy/duplicate documents prior to merging so we do not have to upload them once again.
Recommendations to others considering the product:
If you work remotely, I highly recommend this program. We love being able to email employees and clients in a matter of minutes for documents requiring information on their behalf.
What problems are you solving with the product? What benefits have you realized?
We are solving travel time and time with paperwork with all of the documents be readily available with just a click. Prior to PDF, we were having to meet with new employees for paperwork. Now, we are able to email them and have them sent back for processing. Our time is being used in a for efficient manner.

Edit and create PDFs easily If you work daily with PDF documents, this is a must for you It has a lot of PDF Tools in one on the cheapest plan Maybe they can unify the first and mid tier plans. They don't add a lot to the mid tier plan to increase the price. It just don't worth it

The customer service is absolutely the best I have ever encountered. Super supportive, super polite and super efficient. Would I recommend it, duh.......1000%!!! What do you dislike? Absolutely nothing! And I am not a company shill, just impressed! What problems are you solving with the product? What benefits have you realized? Just being able to fill out pdf forms simply and easily.

I mislead them on my intentions for the service level that I required. Once I brought it to their attention, I answered 3 questions; and the matter was immediately resolved. Outstanding customer service comms. !!!

The PDF filler is amazing The PDF filler is amazing. It has solved me in so many situations since being in isolation due to the fact that I do not have a printer. So easy to use. The only feedback is the date component is fiddly and doesn't always work but other than that - perfect.
