I am too Busy at the present time but I find the program very helpful. I would like to review the program after I get into it in the tax season for more comments.

I enjoy updating documents without creating a entirely new document. I wish there was shading an area after you erase to match the background of the document.

The greatest part about this site is being able to search for all of the various different forms you need. Turbo Tax wanted $159 just to fill out tax forms only needed once a year. Saving a ton on this site!!

My subscription had expired My subscription had expired. I was trying to reactivate my account with a discount offer that was offered to me before my account had expired. Unfortunately I couldn’t seem to figure this out. I was connected to Katrina using the live chat. She explained to me because my account had expired the offer was no longer available. She did however offer me 25% I accepted what was proposed to me. Yet again I was still having problems figuring out how to get this discount link Katrina had sent me. She eventually emailed the link to me because the computer and myself don’t see eye to eye and I can’t figure out how the thing works sometimes. Katrina was very patient and understanding. She helped me figure out my dilemma. Thank youMathieu

What do you like best? The ability to change/save PDF files, the online signatures, the ability to delete unwanted pages in a PDF. What do you dislike? The auto "next" field selector thing...I figure out a way around it, it's just annoying. What problems are you solving with the product? What benefits have you realized? I'm a CPA and I can easily type important forms for federal and state governments to keep them professional and easy to read.

Not very user friendly Not very user friendly. The "sign-up" commitment is not good... Inevitably some people will forget to cancel and then will be hit with a high annual charge...

I'm still learning! It's been really helpful working from home. It could be a little bit more user friendly, I had to start using it suddenly due to being quarantined,

It's essential for digital nomads It's essential for digital nomads. Since my base is in the US. I rely on these solutions to continue operations in the US from abroad. I would integrate payment systems, especially with the banking networks to be able to send money orders or checks physically. And I would suggest connecting with virtual offices to be able to interact with clients in a virtual office setting. I'm thinking a virtual secretary solution... just some thoughts to improve. Abe
