clients have a hard time opening documents to sign. they get an error message or just can't open to sign. Sometimes it takes hours for them to receive a document. Clients also have a hard time printing out a form they signed

It had some really great features but not as easy to maneuver through as I thought it might be. Was expensive with no other option for a company that does not need it that much.

The system works very well. While trying ot the product I had no issues at all. it is a very good product, just that after using it, my agency did not accept the forms.

Look no further than pdfFiller!
As a person 70+ years old, new programs are usually a challenge for me. However this was not the case with pdfFiller, it was so easy to click on the area and type and being able to alter the text size to fit was a bonus. I highly recommend this program and can vouch for customer support who are there to help.

Ease of use was great and intuitive
Ease of use was great and intuitive. Documents went from PDF into a word document really nicely. The only issue with changing PDF into Word docs is the font comes out a bit weird and can't seem to be corrected.

How do I add fields to a PDF?
Click the Add New Field option in the right sidebar menu, then click the Text Field option from the New Field menu. Remove your placeholder text and click inside the PDF document where the field will appear. Next, drag the cursor to widen the field to the desired length.
Why isn't my PDF fillable?
Make sure that the security settings allow form filling. (See File > Properties > Security.) Sometimes form creators forget to convert their PDFs to interactive forms, or they intentionally design a form you can only fill in by hand. If you can't type in the form fields, then the fields are probably not interactive.
How do you convert a PDF to a fillable form?
Step 1: Load the PDF File. Open your pre-existing PDF form in PDF element, or you can choose to open an existing form template.
Step 2: Recognize Form Fields Automatically.
Step 3: Fill and Save the Form.
