I must admit, I'm very grateful to the leadership of this organization; and the quickness in resolving issues raised by subscribers, like me. This is my second year of being a part of this wonderful and truly a required program for someone like me in my Income Tax Preparation Organization. Your services is quality and the availability of your program is impeccable. Without you I would be lost trying to prepare 1099MISC for my small business clients. Thanks for your continued supports and availability of your support staffs.. Truly yours Max Taylor p.s I noticed that you have a Massachusetts phone number .. I'm actually from Cambridge, MA and attended Bentley(college) University in Waltam, where I studied Accounting&Finance and now runs my own tax preparations and financial services firm here in Northern Virginia.

On first blush,this is a fine tool. I have a limited number of documents. So this works great. Simple. Easy to follow. Support answered some not so obvious questions quickly and easily. Well done. I have one question or suggestion..I would like to merge a couple of my documents...but don't want to pay for a full upgrade for just two or three uses. Can you offer a "yeah we'll let you do this" one off pricing for someone like me? Would be very helpful. (I will also say I tried several of the competing products...and this was far easier to use)

Seems user friendly for the most part. It would be nice if the documents could be automatically opened in Drive without all of the signing in process each time

But the important thing is they indicate that it is free to use online, but they demand that we subscribe to make a charge, then we do not have the link to cancel

This has made me much more efficient at my job! I am having a lot of trouble with handwriting in these forms that I have to complete daily. This has saved so much pain from writing and has really increased my efficiency!

Edit and create PDFs easily If you work daily with PDF documents, this is a must for you It has a lot of PDF Tools in one on the cheapest plan Maybe they can unify the first and mid tier plans. They don't add a lot to the mid tier plan to increase the price. It just don't worth it

I have really enjoyed using the software. I use it on my iPhone, on my windows PC, on my Mac and my iPad so it's a multiplatform Holy Grail. I still use the program. Have it installed on all my computers and IOS devices. there are a lot of features that I've not used so I can't truly say much about them, but overall I'd definitely recommend the program to others.
