Should I be attaching my supplier invoices to bank entries or creating separate expense entries? My QB balance is out against my actual bank balance. Matching?

Hi there, Affinity888.

Welcome aboard to the QuickBooks Community. I'd be glad to lend a hand with your concern about the supplier invoices in QuickBooks Online.

If the supplier invoices status is still open, you can either make bill payments or pay them using downloaded bank transactions. For the detailed steps on how to match bank transactions to your existing bills,  I'm adding the article I recommend on this (scroll down to Record payments for existing bills or invoices):

Add and match downloaded banking transactions.

Since there are several reasons why your QuickBooks balance and bank balance don't match, there are things you may need to review. Here's the list of reasons that you can check:

• Outstanding transactions
• New transactions for a connected account
• Duplicate transactions
• Edited or deleted transactions
• Card (liability) account

The complete details and steps on how to fix them are in the article below:
