I appreciate your time today, @flowers59342. I can share some ideas about your concern with QuickBooks Desktop.

If these bank accounts are used to operate the business then it would be best to add them to QuickBooks for tracking purposes of your transactions. You're able to add a bank account even without connecting it to the online banking feature in QuickBooks. It's possible through the Chart of Accounts page and when you record your transactions.

To add them, follow the steps below.

1. Go to the Lists on the menu bar and tap Chart of Accounts.
2. Click the Account button and select New.
3. Select Bank then click the blue Continue button.
4. Enter the necessary details of your bank.
5. Hit Save & Close or Save & New.

See this article for more details: Add, edit, or delete accounts in QuickBooks Desktop.

Also, it is not advisable to mix personal and business expenses. However, certain situations will require you to do so. That said, I would suggest consulting your accountant. They can give you advice on how to handle this situation to ensure your books are accurate. You can find a ProAdvisor near you by following this link: ProAdvisor. 

Additionally, I'm adding these articles on how to review /or match the transactions and reconcile them. This is to effectively monitor their expenses and the growth of their business:
