pdfFiller scores top ratings on review platforms
The log in process is a little clunky. I have not been able to copy paste a field in the template creator. I have 30 fields or so that will each have the same sized field, I should be able to duplicate the specific field a number of times and paste. No?
Both your help and reading the instructions for filling out form 1099-misc were needed to get this done, Seriously, Thanks!
Still waiting on confirmation from IRS!
My experience with PDFiller was fantastic. I was amazed how easy to use!
I already answered this question.
Ability to locate forms and fill out online to produce a very professional looking and very neat document. This product was a winner for me. Save me a lot of time.
I needed to make editable changes to a document in a short window of time. PDF Filler did the job!
User-friendly and it saved the first draft so I had time to purchase a trial run of the software in order to save the final version on my PC.
I wish that I could've been able to log in and get right to my previously saved work faster. The intro screen and the print screen were rather busy.
No Scanning! I'm just PDF Filling
It makes capturing my customer's signature hassle-free as my business is online. No do-overs! Thank you! Because I make it mandatory for them to sign after placing an order. If they decide to change the order, within the specified time, they can sign to that too.
What I like least about this software is that when actually filling in the blanks, the words do not align with the original text. This is an area that needs improvement.
I have only used it once before and I like it. Some of the fill-in spaces are challenging, but I'm sure it is because I haven't mastered the software yet.
Recommended for easy and trustworthy service
I was searching for a safe and efficient way to convert a few PDF file on the internet when I came across pdffiller.com and next thing i did was get a subscription since the tools I used was so helpful and seamless. The customer service is fast, reliable and helpful especially Mr. SAM who helped me with my subscription and account details. Kudos and keep up the great work pdffiller team.
We are an accounting office in Kansas and we have quite a few clients that are out of town and this program allowed us to get signatures with out having the clients come into the office multiple times. I would defiantly recommend this program! We are a small firm so the basic package works for us and it is a reasonable price and the customer service is great, prompt and knowledgeable.
