Hello there, matt_naifeh.

I appreciate your effort when using QuickBooks Online.
 

I got the point on how important to keep things before automatically logged out in QuickBooks. After working for 3 hours, you'll be prompted to re-enter your User ID and Password. With that, I'd recommend saving everything before the maximum hours' end. It's how to keep all the transactions entered into the program.

It's a good idea to get a warning before the time-out session. I’ll take note of it. You may want to visit our blog website to check for new updates and features that we have. 

Keep me posted if you have other questions about QuickBooks. I'll be here to help in any way that I can. Stay safe.
