Syncing your account to the bank feeds in QuickBooks Online is the best way to make the most of your bookkeeping in the cloud. I'm glad you're taking advantage of all the features available to you in QBO. I'd be happy to explain how you can make a different customer selection for your transaction if QBO has categorized it incorrectly.
When your transactions are imported from your bank's website, QuickBooks Online will make suggestions based on previous transactions in regards to the customer, supplier, or category it thinks will be a good fit. These are simply smart tools that make recommendations, but you're still able to change it if QBO didn't get it right.
The review process allows you to select Customer B if QBO has selected Customer A by mistake. All you have to do is click the transaction, then select the right customer from the Supplier/Customer drop-down menu.

Your transaction will then be matched to the correct customer. You can learn more about undoing and matching bank transactions in the following articles:
