Good to have you back, Chai Wanma.
Thanks for reaching out to the Community for support. I'd be glad to help you with your concern.
Yes, you're correct. When you buy QuickBooks Online Plus version, you can add up to 5 users and let them log in at the same time.
I also encourage visiting our Community Help page where you can find tips and articles to help you while doing a task in QBO.
Please let me know if you have any other concerns. I'm always here to help.
