How do I match multiple bank transactions to one receipt ?

Hi there, @MossE.

Currently, the option to match multiple bank transactions to a single transaction in QuickBooks isn't available. To get this resolved, you'll want to clear the sales receipts you recorded within QuickBooks and exclude the downloaded bank transactions. Let me guide you through the process.

First off, let's exclude the downloaded transactions you want to match to a single sales receipt. Here's how:

1. Sign in to your QuickBooks Online (QBO) account.
2. Click Banking from the left menu.
3. Select the bank account from the list.
4. In the For review tab, select the transactions you want to match.
5. Click Exclude.

Once done, you'll have to manually clear the sales receipts from the Bank register.

1. Click Account from the left menu, then select Chart of Accounts.
2. Find the bank account and click View register.
3. Locate and select the sales receipt.
4. Under the reconciliation status column indicated with a checkmark, repeatedly click the box until it displays the cleared ( C ) status. 
5. Click Save.

Once everything is set, you can proceed with reconciling accounts in QBO. This is to ensure your bank and credit card statements match in QuickBooks.
