The tool is a little hard to learn at… The tool is a little hard to learn at first and takes some exporting and testing to settle on desired outcomes but was very happy with the end result. I canceled my use as i only needed it for one document but if i were regularly building docs like this i may have kept it.

I used this for a work purpose I used this for a work purpose. It made my task a lot easier. Only needed it as a one off, so cancelled my subscription by contacting them. Fast, efficient customer support.

Good overall experience pdfFiller does have a robust feature set for all document needs and the user interface was pleasant to use and mostly intuitive. I believe that a market for single users is far less likely since a normal user would not require most of the features that pdfFiller has to offer and they would probably not use the paid version. I would give 5-stars but you have to sign up in order to download your PDFS/Docs, i would recommend that you allow at least 2 Docs to be edited and downloaded before requiring sign-up.

I really like the capability of downloading forms, completing them and signing to send off. I wish I did not have to log in each time. That would be a great plus as I work for several clients and need the quick ability to do a form and send to them. Thank you Alice

Most designers use asterisks to indicate the required fields. But it is necessary to stop, the research on the subject is clear, and it is already the case for quite some time, used asterisks for the required field is a common mistake.
”Field is required” is a flag that has absolutely nothing to do with screens. You either need to remove the flag in the field configuration, making it optional, or you need to add the field to the screen, so the user can obey the mandatory rule you've set.
Mark optional fields, not required Most designers use asterisks to indicate the required fields. But it is necessary to stop, the research on the subject is clear, and it is already the case for quite some time, used asterisks for the required field is a common mistake.
The bold fields mean the column header is required. If you are not going to populate an optional field for all rows in a data import file, it is best to omit that optional field entirely from the file. School_id, for example, cannot be included and left blank for all rows.
Mandatory fields are questions that must be answered before the form can be submitted. Mandatory fields are also called compulsory or required fields. The opposite of a mandatory field is an optional field. Optional fields are also sometimes called voluntary fields.
