pdfFiller scores top ratings on review platforms
excellent, extremely professional and easy to use. Great customer service. Best money I ever spent on the APP Department. Recommended it to everyone. Hands down it is worth your time to investigate.
Mostly good - had a little difficulty when the app decided I could only answer 1 category when I needed to respond to all 5 subcategories of a question. Also, messed with the date - it changed to a different format.
PDF Filler customer service is like it used to be when businesses actually cared if you did business with them, their 24 hour support guys are incredible, unfortunately I am always in such a hurry when I talk to them I X out the opportunity to give them a 5 star Kudos..."Thank you for hiring an amazing group of people which do a great job representing the integrity of your program, you have earned a customer for life", that's what I would say if I could slow down for a few minutes!
Form 1099-misc accepted the data that I entered in each filed, and propagated it to all the required Copies; then prompted me to Submit to the IRS ... This simplifies my execution of Federally mandated processes ... Thank you very much!
Also, support staff is very responsive! Thank you!
A great time saver and gives downloaded documents a consistent and better appearance. The Guide is easy to follow, clear and well organized. Guide is well organized and very helpful. I am using PDFfiler more than I thought I would.
It was easy to sign and save...
It was easy to sign and save my document with no interruptions or gemecs in between. I thought it would of been hard to get it sent via email but that was even more of a breeze.
Work and Study Budy
Overall I love the app and all the features it offer! The benefits totally outweigh the cost. Amazing app!
What I like most about the feature is I can use it both for work to fill out pdf files and for my personal studies where I can write notes, comment, add highlights and more to the file.
What I least like about this is it can be a bit pricey to maintain especially if I were only a student. But good thing I am also using it for work so I can really maximize its use.
The level of communication the team has…
The level of communication the team has is second to none. Best customer experience. I recently tried the free trial, I forgot to cancel after the free trial because I needed their service @ that time only. When then cancel my subscription I didn't get a refund, but the team explained to me why that happed if do want a refund what should I do.I then followed the steps and within the time they said , I got my refund. Keep up the great work team
This is a great program if you need this service. We needed it at one time, but did not realize we could do this on line. I would recommend it to anyone who is in the business of needing documents filled out, signed and delivered.
