You can track multiple companies under a single Intuit account, Bwahl. Let me provide you with valuable information on how this works.
Please be aware that QuickBooks Online operates on one-entity per subscription basis. This means that each company requires an individual subscription, but you can conveniently use the same login credentials across multiple companies.
While you can access all them with the same credentials, you must manage your financial data and records for each company separately. This will ensures that each of your business information remains accurate and organized.
Furthermore, if you manage multiple companies with separate login details, you can consolidate them under a single Intuit account. For guidance on this process, please see the following article: Use one user ID to access multiple companies in QuickBooks Online.
