The portal and the ability to send the return for remote signature in a way that is IRS compliant directly from the return (the return locks as soon as you do it) saves me a lot of time on the back end. I tried to modify the client letter to add additional penalties and interest one time that I was able to make the return calculate but ended up having to add a sortof general note to the client letter to save time completely rewriting it or developing an entirely new client letter template within the program that would achive my objective which was annoying to me coming from a background using Profx and Gosystems and having a relative mastery of those programs. There were a couple of instances on local returns where I think they should have had a diagnostic even if they weren't going to autopopulate certain values that I think they should have assumed or forced me to override a field that I don't think they should have forced me to override to get something 100% right. I have had no major issues with the federal returns beyond some initial difficulty on certain inputs that I'm not sure all preparers care about. In terms of the payroll add-on that came with my package that I only used for 1099's once the delay in finding out that an attempt at e-file was rejected was very stressful for me but also taught me that certain software that I used previously had more features for printing purposes (Dr. Etc.) that don't actually translate over to what the IRS receives and therefore shouldn't really be an option for other systems, but the failure in a few instances to recognize the error in advance made me distrust the system but I might try it again next year. I have also seen apparent improvements in areas where I had an issue before, so it does seem like they listen to feedback and attempt to continuously improve and their support has been very well mannered and responsive. If the core product in terms of flexibility and diagnostics were on the level of certain CCH or Thompson Reuters products that I used when I worked for larger firms the technology, the integration of the portal and e-signatures would make this a superior product. I recommend it if you do a lot of individuals and some business returns like me. Not perfect but amazing for the price point.
