I love PDF filler. If you have any new software that you need trials to be done on, I would love to test it. Thank you PDF Filler for saving me on many occasions!!

Has a lot of features which will be most beneficial as soon as we learn to use them. Is an easy program to enter information into for forms and hopefully the longer we use it the more efficient we will become. Such as the feature of creating a template from a form instead of what we did which was to do it over and over again, and not recognizing the way to save it online.

extremely convenient and fairly easy to use, but i need to find time to sit down and learn more features other than just filling out forms and signing them. I think the vvalue of a yearly subscription is very good.

Difficult to naviagte
Frustrating... but it may work better on a computer rather than an ipad.
I like that you can create password protected files and templates to sign if there's is sensitive information needing to be shared.
The overall function seem to be helpful, but difficult to use on an ipad for sure! I found it difficult to attempt to build a template as you cannot move the fields you create once you place them. It can make for a sloppy look in your template.

Good. I used to use Docusign but they ruined everything by not allowing direct access to an existing account within email. It would be good if you could do that btw - when you preview a document in gmail you should be in the dropdown list of options for opening the doc and editing it.

secure tool for digital signatures
Overall I have had a flawless experience using this software.
The authentication and signature features are most important for my business and I use then frequently without any issues.
I have had no issues using this software.

i app works well once you find the form you need. I'm having a problem creating new forms or updating existing ones with new information while saving the old ones.

So far my experience have been great. I think its very easy to use. I am very interested in your mold inspection report. I would like to know more about how to enter my logo and just how to navigate the report templet to meet my own needs
