How do I locate the bank details I have paid a supplier invoice to?

Hello Lisa,

Before proceeding, could you confirm whether the payment was manually recorded in QuickBooks?

If so, please note that QuickBooks Online (QBO) serves as a bookkeeping tool for tracking transactions. It doesn't facilitate direct payments to suppliers. Here's an article that explains how to locate supplier payments based on their recording method: Learn the difference between bills, cheques, and expenses.  

For payments made outside QuickBooks with a linked bank account, navigate to the Bank transactions page in QBO to locate the transaction. When a payment shows in the transaction feed, it confirms successful processing. In such a case, the supplier has to follow up with their bank to ensure the funds are received.

For unlinked accounts, review your bank statements directly to find the payment details.
