Hello there, @skyemb.

I appreciate you coming back to the thread and for your patience about this matter. You'd be glad to know that I can share the possible reason for this issue and and a way to fix it.

To start with, the possible reason why there's a customer that's "Unmatched" is due to payments that wasn't link to the customer's invoice. So, when recording a deposit we need to make we are following the right workflow.

On the other hand, we have to link the deposit to the invoice for the resolution of this concern. Let me guide you through the process.

Here's how:

Step 1: Find and edit the deposit in your bank register.
 

1. Go to the Accounting tab, then select Chart of accounts.
2. Locate the account you deposited the payment to and select View register.
3. select Edit.
4. From the Add funds to this deposit section, find the deposit.
5. Click the Received From dropdown, and select the customer.
6. Tap the Account dropdown. Choose Accounts Receivable.
7. Then, select Save and Close.

Step 2: Apply the deposit entry as an invoice payment
 

1. Click on + New and choose Receive payment.
2. Select the Customer from the dropdown.
3. From the Payment date field, enter the day you received the payment.
4. In the Outstanding Transactions section, select the invoice you need to mark as paid.
5. Under Credits, select the deposit.
6. Then, select Save and Close.
