Thanks for reaching out to the QuickBooks Community with your question. I can help you with your question. QuickBooks Online is not connected to outgoing payments at all; it's strictly record keeping only. Feel free to reach out with any other questions that you have.
thank you for reaching out. Quickbooks records your transactions for you when you have your bank account connected to your account, which makes recording time way more easier. However, you are unable to pay from you QBO account to your bank account.
