The greatest part about this site is being able to search for all of the various different forms you need. Turbo Tax wanted $159 just to fill out tax forms only needed once a year. Saving a ton on this site!!

What do you like best?
I can send as many documents out for signature as I want. No restrictions. I used to use Adobe, but they had a cap on the amount of documents you can send for signature. When I tried to get that upgraded, they had outlandish prices for this same service. With PDFfiller, I can send all the documents I want and I'm also able to save all of them securely.
What do you dislike?
I wish the PDF conversions didn't come out like pictures. When I convert a PDF to Word, it always comes into Word as a picture instead of being able to edit the document. As a recruiter, I receive a lot of resumes that need some work before we can submit them to clients. I still have to use Adobe for this function, so now I'm paying for two PDF programs. I can't just stay with Adobe though because of the above mentioned issues.
Recommendations to others considering the product:
If you need eSignatures, this is the program to go with.
What problems are you solving with the product? What benefits have you realized?
Remote onboarding is a breeze with PDFfiller. I am able to send HR documents to people across the country and still get them to work on time. I'm in VA and have to get employees to work in all states across the country, as well as oversees. We have to get documents to them for signature and faxing doesn't always work. With PDFfiller, we can send anyone any document and get it back fully signed by them. It's truly wonderful.

I signed up for a subscription but only needed it for one document. I canceled but was charged again a month later. I canceled again and contacted customer service. They said the first cancellation must not have completed but refunded me the money. That is great customer service. I will definitely use them again.

Excellent service. Website is easy to navigate and the forms available are excellent. In my case, even though the website is user friendly, I think a short webinar to familiarize customers would be of great benefit. I would certainly recommend PDFiler to others.
2021-02-27
I would only add that when adding text to the editor, it can be moved without blocking the height. Sometimes the PDF blocks the location of the text and it is difficult to align it with the original text.

Wonderful Experience with this software…
Wonderful Experience with this software so far. very affordable also. Editing features are user firendly and easy to use. Also does the same basic things as Docusign if you want to esign a document by several different recipients.
