Thanks for coming back, Jonnybegood.

Let me continue to help you with matching deposits in QuickBooks Online (QBO).

Here's how to match deposits to the invoices:

1. On the For Review tab, select the payments one-by-one.
2. If the option in the Action column is Match, change the Find match to Categorize.
3. Select the Categories (the accounts) you want to split the transaction into, then enter an amount for each split.
4. Select a Customer for each split, then select Apply and accept.
