When reviewing a receipt I have to select a bank account, does it matter it I later match it to a transaction from a different bank account?

Welcome to the Community, amy. Let me address your concern about assigning a bank account and matching receipts in QuickBooks Online (QBO).

To answer your question, yes, it won't matter. Regardless of whether you assigned a different bank upon reviewing the receipt as long as the information reflected is identical to the transaction downloaded to the bank, QuickBooks will match the transactions.

Moreover, you can refer to Step 2: Review, add, or match receipts and bills to guide about reviewing and matching receipts in the software: Upload your receipts and bills to QuickBooks Online.

Once done, it is advisable to reconcile your account to avoid discrepancies in the future. Doing so will keep your records accurate.
