pdfFiller scores top ratings on review platforms
I have been very happy with the functionality thus far. I may be interested in a webinar in the future. A survey in a month or two would allow me a better sample to assess how PDFfiller will work to meet my needs.
Very Easy to use and beneficial. Worth the year subscription. A lot of features to choose from. Everything you need for a functioning office to succeed. Although, I wish the Fax Features would be more affordable a month or included with the yearly subscription. I am paying half the price for Fax with another company but would love to port my number and come on board with PDFfiller for the convenience and functionality of integrating my Faxes along with my other documents all in one place. Love this software. I'm excited to of found it and look forward to putting it all to work for me. www.LazcoIncomeTaxService.com
I needed to print but had to wait to get ink for printer. Two days later I couldn't find the document to print and one of the Reps from your company helped me find the documents and I was able to print them. Thank you.
AWESOME program but too expensive
AWESOME program, but the monthly cost is WAY too high. Should charge customers a more affordable price of $10/month. And stop trying to force us to pay for a whole year up front -- what if I don't need it for an entire year? Fantastic features, easy to learn, a pleasure to use. Just TOO EXPENSIVE.
