5.0
What do you like best?
The best features are (1) the ability to easily import and that it converts with accuracy and (2) the ability to manipulate doc - more specifically merge, edit, copy, etc.
What do you dislike?
The only feature that does not seem intuitive at times is the folder structure and how the files are organized. When editing a doc it will always move a doc to the top because it is the most recently viewed or edited doc - but this sometimes makes it confusing. Similar to Outlook, it would be nice to have easier drag and drop feature for organizing the docs.
Recommendations to others considering the product:
This is a quick out of the box product, overall very intuitive and easy to use.
What problems are you solving with the product? What benefits have you realized?
Able to import and edit docs as well as having them signed online.

What do you like best?
I use Quickbooks and have to send out 1099NT which is not a capability in Quickbooks. 1099 forms must be scannable and I can purchase the printed forms and fill it out on PDFfiller. I can then print on the scannable forms and they are perfectly aligned. Saves time and money. Also, I like the fact that I can create a template so I don't have to re-type the same company information, tax numbers, etc. The product is easy to use.
What do you dislike?
I don't really dislike anything about PDFfiller. Other than maybe the fact that I probably don't use it enough to offset the cost.
Recommendations to others considering the product:
Easy to use - I intended to use for a month and then cancel, but I ended up keeping it.
What problems are you solving with the product? What benefits have you realized?
I mostly use for 1099NT's as mentioned above. I really need to explore!
