matching a deposit to a transfer

Happy to welcome you here in the Community, @Ahmed CPA. It'd be a pleasure to help you match the two entries and reconcile the account.

First, you'll want to categorise the Received A$28,450 to Accounts Receivable associated with that specific customer. For the customer invoice, you have to receive payment on the invoice and make sure to apply for the credit. Here's how:

1. Go to Sales and select Invoices.
2. Locate and click on the specific invoice.
3. Select Edit invoice.
4. Click Receive Payment.
5. On the Outstanding Transaction, put a checkmark on the box of the specific invoice.
6. Click on the dropdown arrow in the Deposit to the option, then locate and select the Undeposited Funds.
7. Click Save and close.

Next, create a transfer transaction from the first business bank account to the second business bank account in QuickBooks Online. It will move the money from one business to another. Here's how:

1. Go to + New.
2. Click Transfer.
3. From the Transfer Funds From the dropdown list, select the bank account that the money is coming from.
4. From the Transfer Funds To dropdown list, select the bank account that the money is going to.
5. In the Transfer Amount field, enter the amount being transferred.
6. Edit the Date field.
7. Enter a description of the transfer in the Memo field (optional).
8. Choose Save and close or Save and new to complete the transfer.
9. Click Yes if you double-checked the date.

Lastly, if your online banking is connected to ANZ, you'll want to utilize the Find match feature to match the Transfer (deposit). I'll show you how: 

1. Go to the Banking menu, and select For review tab.
2. Click the transaction and select Find a match.
3. Look for the match transactions and put a check in their boxes.
4. Select Save.
