Hi emmadebarry
AccountRight online on the desktop and in the browser are two different things:
1) Your current AccountRight file can be put online in your desktop app and it will have the same features as you currently have. The only difference is the file can be accessed in the cloud and you will be able to use STP2.
2) AccountRight in browser means that you can access your company file without installing the software as it only requires a web browser to login. But this can only be done once your file is put online in the desktop app as explained in step 1.
Therefore, for accessing STP2 and for using AccountRight in the browser feature, you will be required to put your file online in the desktop app. Please let me know if you have further questions and I will be happy to address them.
