is it possible to assign multiple roles to a single user in QB online.Also how can I forbid the accountant to enter journal entries for the previous day?

Assigning multiple roles to a single user and limiting your accountant's ability to enter journal entries for the previous day are great ideas. Let's submit this to our product engineers, Haitham.

QuickBooks Online and QuickBooks Desktop are distinct platforms, so some features and user access options differ.

While it isn't possible to assign multiple roles to a single user and restrict an accountant for the previous day, we can submit these ideas to our product engineers.

They will carefully review your ideas for future updates to improve our product capabilities. Here's how you can do it:

1. Head to the Gear icon, then select Feedback.
2. Enter your ideas in the box provided and click Next.

To know the maximum number of users you can add to your account, refer to this article: Usage Limits in QuickBooks Online.

For future reference, you can generate a Profit and Loss Comparison report to analyze your income and expenses across different periods.

I recognize the importance of these functionalities in controlling your users' roles and access. Your ideas are instrumental in guiding our product engineers to review and refine our products effectively.
