I'm here to provide information on how to add another company to your QuickBooks Online (QBO) account, @lab1323-students.

Please note that in QBO, each company file requires a separate subscription. To add another company to your account, you'll need to subscribe to a new plan and use the same login credentials to manage multiple companies under one account.

Here's how:

1. Visit our Plans and pricing site and choose a plan.
2. You’ll have the option to add payroll; if you don’t wish to include it, simply click Continue without payroll.
3. Fill in your billing information and follow the on-screen prompts to complete the process.

Additionally, you can refer to this article for video tutorials to get started in QBO: Watch step-by-step videos to learn your way around QuickBooks.
