What do you like best?
The program is very quick and easy to use. Uploads your documents very fast. You can type or alternate any pdf or word file. It saves it in no time. You can go back and look at any file you have uploaded. Everything is saved. I also love the fact I can use it on my phone as well through the app. It is extremely convenient. I can fill out new vendors forms very quick which saves me time.
What do you dislike?
I haven't come up with any problems for as long as I have used it...over 2 years now.
What problems are you solving with the product? What benefits have you realized?
It saves me a lot of time. It is a very convenient and fast way to fill out forms or alternate them. Adding a signature on any form is so easy to do through pdffiller. I don't have to print the form, chase my husband to sign, scan it and then email it. Imagine just uploading your form, adding the signature which is already saved and you're DONE :D

I like how the service is not that expensive and there's a lot of functionality and they keep upgrading their features.
What do you dislike?
They could improve the user interface to be more user friendly in some ways.
What problems are you solving with the product? What benefits have you realized?
I'm able to have my clients sign documents by just emailing them the link and if they make a mistake, they can always open up the link and sign again.

Super helpful for when you get… Super helpful for when you get redundant document from School Administrators that expect you to print and fill out everything from hand. It's 2021.
