pdfFiller scores top ratings on review platforms
would like to get smarter about how to use these a 2 different cases - Non-Disclosure Agreements with my clients, and editting my PDF material easily.
I absolutely LOVE the convenience PDF filler provides for our patients, as well as our front desk staff. The only thing that would improve the service would be a guide that indicates to the patient that they missed a section, so they know to keep scrolling to complete all the forms.
I have tried a few other cloud based…
I have tried a few other cloud based PDF Editors and PDFFiller is the most powerful and easiest to use. Their support has also been great when I had a billing question/issue.
Makes your work Easy, Professional and Reliable!
Efficient and compatible with many universal docs. I look forward to completing all my documents with professional results.
Monthly expenses/costs can become a concern for small business budget. It will be greatly appreciated if these costs were waived for organizations providing resources to support consumers. We work with a United Stated Private Attorney General supporting consumer claims.
Service only needed once
I'm in my 89th year and only needed to send in the form once...I didn't know that I was subscribing to ongoing service. I live on Social Security supplemented by savings so I can't afford $96 per year for a service I only needed once. Thank you for the time I did need you.
What do you like best?
I love the fact documents may be completed and signed electronically without the need to print, scan, and attach anything. It's so much easier, cleaner, and more secure!
What do you dislike?
The only issue I have had, which could certainly be user error, is that one of the links to an informational PDF (it's a read-only document) sometimes stops working. I am made aware of this when I send the link to someone new and the person responds to say an error message appears upon clicking. I have no idea why this happens and it's always associated with this particular document.
What problems are you solving with the product? What benefits have you realized?
Per my comments in response to what I like best, using this tool prevents the need for recipients to print, complete by hand, scan, then attach documents to an email. It's also a more professional-looking and more secure approach to document sharing.
I am a relatively new user to pdffiller, but have found the platform user friendly and does exactly what I need it to. Helping me modernise a lot of statutory requirements for e-signatures and template creations.
When I experienced issues loading documents due to permissions through my work network, the support team at pdffiller responded quickly and continued assisting myself and co-ordinated with my employers IT support function to resolve it within 24 hours, allowing me to get on with my job.
PDFfiller worked flawlessly. The one time I contacted their support with a request they responded promptly and professionally - very impressive. Highly recommend.
