Hi there, Holly31.

Thanks for stopping by the Community this afternoon. I'm happy to provide some feedback for you on the Fixed Asset Manager. The FAM is only usable in single user mode. But don't worry, you can switch to single user mode easily. To switch between modes, go to the QuickBooks File menu, then select Switch to Single-user Mode. 

Once switched you're ready to use the FAM, here's a helpful article highlighting the process. It has info on everything from assigning an account to multiple assets, changing or adding depreciation methods, depreciating an old asset and much more. 

If you have any other questions or concerns, feel free to post below at anytime. Thank you and have a nice afternoon.
