Very helpful tool for 1099. How do you auto populate though. I find it tedious to manually type the same info over and over. Still WAY better than the alternative though. Thanks.

I signed up for the free trial and ended up not needing to utilize their services. I had thought I had cancelled it, but for some reason it never went through, so I ended up getting charged for the full year. I contacted their live chat and a representative named **** was very helpful and got the refund processed right away. Thank you for being gracious and so helpful! I very much appreciate this company's customer service. I will definitely use them in the future! :)"

Easy to find fast and proficient chat support My issue is resolved in under 5 minutes.. I was able to speak with a live confidence human being in under 30 seconds.. I was charged for subscription that I forgot I had subscribed to and I no longer needed and the chat agent Kara had my problem resolved in no time. Locating this chat support option was easy and not hidden amongst FAQs or literature used to distract and deter you from reaching out
