PDFfiller is a great tool to use for editing and templates
PDFfiller allows me to utilize the same forms frequently. As a result, templates or refillable forms ensure document preparation is quicker and more efficient.
Cloud security, ability to easily create templates for commonly used forms, flatten forms after fields filled in when saving to hard drive, in PDFFiller form remains in tact and is editable for reuse, and menu set-up.
I wish PDFfiller would add the ability to add pages to a documents and allow downloading of templates created. Currently, in personal account, PDFfiller allows emailing to recipient to update information in fields, but doesn't allow me to download my template to my hard drive.

I think it is good however I already see methods to improve it. I desire to fax a smart folder of documents I already created. This would be a facilitate faster communication of information as opposed to finding out how to merge the documents and then fax the complete file. All in all, I like the platform. If you may obtain DocuSign options, it would be nice long term perhaps. Many corporations and companies like to use DocuSign.

Glad to have it
Glad to have it. Wished i didn't have to reset with every entry. It should assume you want the same font until you tell the program to change. Gets tedious to change for every number on the page.
