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.
