How do I allocate a deposit payment received in June to an invoice raised in July?

Hello @jgovender-trelli,

In QuickBooks Online, you can much a downloaded transaction to the existing one as long as both the date and amount are the same. Since you received the deposit in June, last month, it is recommended to create a credit note based on its actual date.

This way, you can use it as the payment to close the invoice created this month and match your transactions. You can do so by following the steps below:

1. Go to the +New button.
2. Under CUSTOMERS, select Credit Note.
3. Select all the information needed according to the deposit you received last June.
4. Enter the amount you received.
5. Click Save and close.

In addition, here's an article you can read to learn more about how you can use a credit note: Create and apply credit notes or delayed credits in QuickBooks Online.

Lastly, I've also included this reference helpful with the resources you need while working with your income and sales transaction: Help Articles for QuickBooks Online.
