Perfect Software for Small Business I use this software for my home inspection business to create required insurance reports and include images. It allows me to upload the required insurance form, edit it and add images for the required mitigation and four-point inspection reports. I love that I am able to save my reports, reuse them by editing as needed and organize them in the straightforward filing system. Excellent value for all of the features offered. Easy to use and manage organization. Love the FAX feature, signature, editing and capacity to upload images. Flash feature for uploading images. Settings have to be set and sometimes reset themselves. I use this feature everytime and sometimes the software freezes.

Works well with scanned pdfs to You can wite-out on the page when you need to change some data. You can highlight, it has most features like other pdf programs. The time it takes to upload takes longer than with adobe acrobat.

What do you like best? This platform is so easy to use. I usually get very annoyed with pdf files as most of the other websites I have tried have been a complete pain to make the adjustments I need. PDF filler allowed me to easily add the information, download, and save with my personal E-signature with my toddler on my lap ! I am very happy that I found them and will continue to use them for all my conversion needs. What do you dislike? I haven't really found anything that I dislike just yet. The monthly subscription is a bit pricy if you won't be using it often enough so maybe they could have pricing for example 4 downloads monthly etc. Recommendations to others considering the product: I would recommend What problems are you solving with the product? What benefits have you realized? I have been able to fill out pdf forms to submit documents online. It saves the time of printing the pdf, filling it out and then scanning.

Could be worse for this price I was expecting that it will be worse because I have seen a lot of weird and bad reviews. Especially in their Google extension market. But it works not bad, actually. I can recommend it.

I accidentally forgot to cancel my… I accidentally forgot to cancel my subscription (I only wanted to use the free trial) and my PayPal was charged $144. I freaked out and emailed pdfFiller’s customer support and they got back to me within an hour and refunded me! In the future I plan on using their services (right now I can’t afford it) because of how amazing their customer support is!

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.
Required or mandatory fields are form questions that must be answered by the user before the form can be submitted. The opposite of required fields are optional fields. And this is where users can choose whether to answer the form questions or not.
