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.

Allows me to fill in pdf documents with computer so I don't have to print out and fill out manually. Not sure why text moves to next line below in some cases.

Cost effective and top class customer support,
integrating pdfFiller has been a breeze, my team use it everyday to send out dozens of branded quote documents and it's never failed us.
The main driver for us in this decision was the ability to use our own branded PDFs. The second was the ability of pdfFiller's system to integrate with Salesforce via Zapier.
I genuinely can't think of anything I don't like. It does exactly what it needs to do.

Free not so Free
Easy to use and alter forms to fit my needs. Was disappointed that it seemed to be free until you get to the end and you have to pay. Thankfully there was the option of the 30 day free trial.

What do you like best?
This platform is an online pdf editor, electronic signature manager and creator of PDF forms, you can send them by fax, obtain complete copies of the PDF forms sent and signed, you can also automatically extract data from Excel, CRM or database data. Share the documents by email, social networks and you can also place them on your company website.
What do you dislike?
We have not had any problems with this platform, the performance has been satisfactory, the pdf files are relatively basic and do not present any type of error, it seemed a good option after using other platforms with negative results, but this has been totally different.
Recommendations to others considering the product:
It is fully recommended, the results obtained have been very gratifying and satisfactory. You simplify a large part of the work that allows you to save time even you maintain a constant work flow. Share documents through email, social networks among others. In general it is very complete and a good option for all companies.
What problems are you solving with the product? What benefits have you realized?
We use PDFfiller, to obtain and receive forms from our clients, sending e-mail is excellent to communicate, this drastically reduces follow-up time and interaction failures with our work team. We also obtained a significant increase in work flow since I simplified the handling of many documents such as W-4 in addition to insurance renewals and bank authorizations. We perform a conversion of file formats such as Word to Pdf daily and with ease, we are happy with the results.
