You can run a report to see transactions for a specific vendor over a set timeframe using the Transaction List by Vendor report in QuickBooks Online, @Nolabrewer. Allow me to discuss this further.

To begin with, If the deposit is tied to the customer, it will not appear under a vendor transaction. However, if the deposit is accounted for as Accounts Payable (AP) specific to the vendor, it will show as a vendor transaction and can be pulled up using the Transaction List by Vendor report.

Also, to assist you better may I know how you entered those client and vendor transactions? I would much appreciate it if you attached a screenshot.
