My QuickBooks won't let me print W2's unless I sign up for their payroll service. We have 2 employees! Not worth the expense! With PDFfiller, I was able to print W2's for much more reasonable price!

It was very easy to use and was user friendly for using the icons to understand what I was doing. Process was a little slow, but I think that was my computer!

Great customer service support Great customer service support. They have always been responsive on a timely manner when I need help. I use them to submit 1099 forms to the IRS. They even developed a 'fix' to their form so that I could submit a form for an employee that lives out of the country.
Anne Underwood
I'm not sure why Adobe Acrobat Pro… I'm not sure why Adobe Acrobat Pro isn't this easy to use. Adobe Acrobat Pro feels like it was created in a silo by people who don't do editing on a daily basis. Also, it doesn't install, on one of the latest Macbooks on the planet. Thank god for PDFEscape and PDFFiller. Thank you god.
Zephyr Khambatta
Free not so Free Easy to use and alter forms to fit my needs. Was disappointed that it seemed to be free until you get to the end and you have to pay. Thankfully there was the option of the 30 day free trial.
K. Forrester
I had an issue with accessing a form shared by a colleague. I wrote to the PDFfiller support team and received their response very swiftly. The instructions received via email were very clear and easy to follow. I was able to fix the issue within a very short time. I'm really impressed by the efficiency and quality of customer support.
