Greetings suzeta20,

Thanks for joining the thread. I'd be happy to help you reassign the payment to the correct customers.

To clarify, did your deposit transaction also come from the Merchant Service Deposits screen? If so, you'll need to get in touch with our Merchant Services Team as well, just like Hampty did.

However, if it was manually created within QuickBooks, then you can simply edit the deposit and apply it as payment to the right invoice. The steps below will guide you through the process:

To edit a deposit transaction

1. From the Lists menu, choose Chart of Accounts.
2. Double-click the bank account where it's located.
3. Change the name entered in the Received From field to the correct customer. Also, make sure the From Account is using Accounts Receivable.
4. Click Save & Close.

To apply the deposit as payment

1. From the Customers menu, choose Receive Payments.
2. Select the correct customer from the Received From drop-down menu.
3. Click the Discounts And Credits button.
4. In the Credits tab, select the deposit in the Available Credits section.
5. Click Done.
6. Select the appropriate invoice.
7. Click Save & Close.

I'm also including this helpful article for additional insight about this process: How to link a deposit to an invoice
