Thanks so much...
I needed to complete the Appraisement of the Estate Report for my mom's estate. This program made the task easy for me under the emotional stress that I was unde
Everything is wonderful
Everything is wonderful, however with my bad eyes and being slow, i still say it is great.Sometime I have a little trouble moving from are moving to the area to get going to the PDF. It is not you it is me just a little slow. Can not see that good. I am good enough to get my job done.
It has worked well. Minor issues that were easy for me to figure out. I wish there was a vertical line to assist in lining up edits needed on the documents once in pdffiller. Also it would be convenient to have an all document pagination - or if there is one, ease of finding it.
Working Experience With PdfFiller
i am using this software for about 8 to 9 months. the best thing i found in this software was its feature to send the file online without makuing sure to save first and then send. other feature i liked the most is that i can easily edit the pdf format by using this software. it is really very favorable feature to avoid the conversing to word file for editing.
in my opinion, there must be improvement with the font size of editing text to make it more compatible with text. i face a problem to make the ediding in the same font size . Althorugh, it is same as that of text but it seams different. it makes the file less professional.
I used the free trial to compile rent due ledgers for the ************** requirement. I did not cancel on time and was charged $180 dollars. I reached out to support and ****** returned my email within minutes. I provided my information to customer service specialist ****** and he fixed the problem. There wasn't any back and forth emails. It was straight to the point. Thank you ****** for being quick and professional.
What do you like best?
Price is good and plenty of document options.
What do you dislike?
Would be great if it could integrate with your pdf documents without having to go to the website. maybe a feature where you can join or delete parts of the pdf without having to upload it to the website every time.
What problems are you solving with the product? What benefits have you realized?
All my PDF needs are being filled by the software
Honest business practices
Like many other online products, they make it VERY easy to sign up, and not so easy to cancel. But once I found the correct place, they did allow me to cancel and refunded my money quickly. While the product did not fit my needs, the company appears to be legitimate and honest.
I was absolutely thrilled with Anna's help when I reached out for my PDF Filler issue. She responded quickly, took screen shots and sent videos to make it easy for me to understand what she was teaching me and was friendly too! Really, I couldn't have been happier. I'm so grateful to know that PDF Filler has invested in ensuring a great customer experience with their support as it makes all the difference!
