Very self explanatory and easy to use. Also being able to save my work in word is very helpful. Easy to save, send and print. Second year using this website and worth the small price.

some forms are not as well created. would be nice to be able to tab between fields. or when clicking in fields that should all be within the same horizontal line it would be nice if they automatically lined up rather than having to be moved like individual text boxes.
Anonymous Customer
I absolutely LOVE this program. However, I hate the pop-ups with the NEXT button. This isn't a feature that I need, and is very annoying. Please add an option to turn off this feature.
Anonymous Customer
I've only just started using it, but so far; I am loving it. It's easy to use, and very useful with my work. I'm an RN and I work as an independent nurse, so having this program is so nice for my plans of care, and sending them to the physician to get signed is easy peasy! Thank you.
Stephanie Lee B
Great customer service I signed up for a subscription when I really only needed to use it for one day. I canceled the subscription but it must not have gone through because I was later charged after a month. I canceled again and contacted customer service. They said the first cancellation must not have gone through but then refunded my money. That is why I will definitely use them again in the future.

Amending the future The software is designed to edit PDFs. Makes updating documents and personal files very easy. I wouldn't change anything for this product.
Kory O.
What do you like best? Easy to use when you need a fast, effective solution. What do you dislike? The email interface is a little cumbersome, but still very usable. Recommendations to others considering the product: Easy to use and deploy. No licensing to worry about and no updates! What problems are you solving with the product? What benefits have you realized? Filling out and modifying .pdf's. Also applying my signature to documents.
Nate Griffin
What do you like best? This program makes it very easy to enter data into pre-printed forms instead of using a typewriter. What do you dislike? Sometimes there will be a data box over another data box and it makes it difficult to change information. Also, when you highlight and change or add to preexisting words the formatting changes and you can not change it back to look like the original What problems are you solving with the product? What benefits have you realized? Not having to ever use a typewriter is the best benefit. Having all of my previous files stored is highly appreciated.
Administrator in Accounting
Superb customer service and an amazing program! I used the program several times. I love all the features and it’s super easy to use. Highly recommended.
