Easy-to-use program once you fiddle with it awhile. Would like ability to edit text also (portions that are inapplicable rather than striking through).

I may be an idiot but it isn't the most intuitive experience I've had. I have been under pressure to produce so that may have something to do with it.

I join the annual personal plan and it says if it is annual you will got 65% discount on the $72. However, I noticed after payment that I did not get any discount.

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!

I must say "PDF filler" is the best… I must say "PDF filler" is the best company I have ever had the privilege of dealing with. Such prompt courteous service when you have a question. If you call their phone # and have a wait, just leave your number. They will actually call you back ASAP the same day. Found that out with surprise!! Wanted to cancel my subscription. No problem she said. Got an email on that the very next day. The only reason I cancelled is the 4-page form I needed to type out is just once a year. Loved the selection of type styles and sizes. Made it a pleasure to fill in.

Great for .pdf that You Need to Edit-PDFfiller is the way to Go! Great for doing 1099s at tax time! Wonderful for use with prefab downloadable boilerplate documents that you purchase from the web. Great storage for being able to go back in and repurpose a saved document for an additional use. Print alignment not always spot on for forms, such as 1099s and you have to play with settings a bit, but overall not too cumbersome.

What do you like best? I print and distribute numerous emails every week. As such, I have tried quite a bit of PDF software over the past several years, I have seen that pdfFiller does everything I need, every time, in an easy-to-use way. There is none better for the price. What do you dislike? At times, it is difficult to find a saved file from within Google Chrome. Recommendations to others considering the product: Before making a selection, make sure to use evaluation versions. It's a shame to get saddled down with something and later discover that it's not right for you. What problems are you solving with the product? What benefits have you realized? There is one peculiarity that I encounter every week. The first file that I modify is saved in the appropriate folder, and the browser shows me where to find it. For some peculiar reason, I have a hard time finding every file that I save after that. It could be an issue with the browser.
