Can I use this program on other devices, home computer & laptop. I have tried but it asks me to set up new business.
You can install Manager on as many computers as you want. If you subscribe to the cloud edition, you can log in from them all using any web browser. If you use the desktop edition, you’ll need to change the default application data location to a drive accessible by all. Make sure you run the same version of the software on all machines at all times. For information about transferring data files and changing storage locations, see these Guides:
