Let me share information on the number of users you can add to your QuickBooks Online (QBO) plan, Andre.
The number of users you can add depends on your current subscription, regardless of being a trial version. The QBO Simple Start plan allows only one user. If you need up to three users, you can consider the Essentials plan. The QBO Plus plan allows up to five users, and the Advanced plan lets you include up to 25 users.
For more details on the features available in each subscription, you can visit our pricing page here.
Additionally, here's an article to guide you through upgrading your account: Upgrade or downgrade your QuickBooks Online edition.
I'm also including an article on managing user permissions in QuickBooks for your reference: Add and manage users in QuickBooks Online.
