The best service ever! As a chiropractor, I am able to fill out my exam and soap notes with pdffiller then save them in the encrypted files for Hipaa compliance. My office is on its way to paperless as we speak. I love this service. Highly recommend it to all.

I am in a struggle with the Home Office. I have to fill out multiple forms repeatedly. I bought Adobe but it did not work. This software is very straightforward and I am sharing the document with my Barrister, which saves me money, time and avoids confusion

What do you like best?
We use PDFfiller primarily for tracking and completing registration forms for the advanced trainings we provide to mental health professionals across the country. Manually managing these forms was a nightmare as our business started to grow. Once we started using PDFfiller, it began incredibly easy and hassle free to monitor who was registered for which trainings and when. the integrated PayPal and Stripe systems make it super easy to allow customers to pay registration fees immediately and we are notified as soon as that happens. Also, PDFfiller offers a digital fax line. In today's day and age, we are completely wireless and adding a hardwired fax line would have been such a pain. For 10 bucks we are able to digitally send and receive faxes which is very helpful when dealing with physicians and other medical providers.
What do you dislike?
We have only had one real issue with PDFfiller. At some point a few months ago, we had some issues with the PayPal/Stripe payment integration. We were unable to send receipts to our customer which was rather frustrating for us and them because of the amount of money people spend to some to our trainings. I reached out to someone at PDFfiller and a manager responded the next business day and said they would get in touch with the team who handles that part to get it fixed. Though I did not hear back, within a week or so the problem was fixed.
Recommendations to others considering the product:
Do it. It is well worth the price for what you are getting.
What problems are you solving with the product? What benefits have you realized?
Sending and receiving faxes through this program is a lifesaver. I am able to access them anywhere at any time whether I am in the office or out of town. It's also a great organizational tool for tracking out "link to fill" forms.

I canceled my trial but maybe I didn't complete it on my end. Either way the subscription was charged to my card and I contacted support which usually is a nightmare when you have billing problems and it was honestly quick and painless. Great service and they got my refund and account canceled quickly. Thank you to ***** from support

The software was actually really great and extremely useful. I didnt really experience any difficulties with it and was exactly what I needed and a quick pinch without having to install anything. There was one small issue with my account, but the support team got back to me within the same hour and resolved what I needed. Amazing all the way through.

The terms digital signature and electronic signature are often used interchangeably, but they're actually different. Digital signatures are a type of electronic signature. Both types can be created online and applied to online documents. In most cases, standard electronic signatures are sufficient.
In Microsoft Word or Excel, open the document that you want to sign. On the Insert tab, in the Text section, click Signature Line > Microsoft Office Signature Line. If the Microsoft Office digital signatures window appears, click OK.
