I am enjoying the service. It is user friendly from a design point of view. I don't have feedback from the recipient experience however I will rate that component once I receive the feedback.

difficult to sign and other parties not knowing the software, I feel I need to be cautious. Too costly for a novice one time user. Overall, it has been helpful. thanks!

On the first day of use, I thought I had lost all the data I entered. I received help via a chat and verified my data was intact. This is going to be an extremely useful product for me as a consultant.

It was fairly easy to search out IRS forms but then you find out they're not usable because they're in Red!?! Also it said if you paid for a one-year subscription you save 65%, but the yearly cost was exactly the same as paying monthly and you didn't know this until you processed your payment???

I am happy I have found your company. I appreciate your east steps to follow. I don't know if I am not understanding how to save each 1500 I complete as I need them to enter new dates as each week comes to bill.

I have used PDF filler a couple of times and so far I love it! Just a little suggestion, maybe you can add/give the option to be able to change the size of the fonts without having to add a text box where there is already one to fill (does it make sense?). Thank you!

Helpful Tool I had been trying to send off some release forms and was crunched for time so I signed up for PDFFiller's free trial. In the end, I wasn't able to use their software without a purchase, but it made me almost wish I had paid the money. I like that I can sign any document electronically. It definitely saves time and printing costs. It cuts out about 2 extra steps: printing and scanning. This is helpful for documents that need signatures such as release forms, etc. I didn't like how much I had to pay in order to use my e-signed pdf. I don't use the software often enough to make it worth the price. However, if I worked regularly with documents that needed to be signed this software would be the very best solution.

Glad to have it. Wished i didn't have to reset with every entry. It should assume you want the same font until you tell the program to change. Gets tedious to change for every number on the page.
