How do you match a bank deposit to an Invoice that has already been matched to the correct payment when made online? None of the tutorials or videos give this scenario.

Welcome to the Community, @Hannk8. Let's get your deposited transactions to match invoices correctly in QuickBooks Online (QBO).

When you receive deposits from your customers, it's important to link them to an invoice to maintain accurate records and prevent errors during account reconciliation.

Before doing so, here are a few things to check:

• Ensure that there's an invoice for the customer.
• Ensure that you record the payment through bank deposit and not through Receive Payment.
• Ensure that you haven’t entered and linked the payment to the invoice.

To match a bank deposit to an invoice in QuickBooks Online, follow these instructions:

1. Sign in to your QuickBooks Online account.
2. Go to the Gear icon, then Chart of accounts.
3. Locate the account you deposited the payment to, then click on View register.
4. Find and choose the correct deposit, then select Edit.
5. In the Add funds to this deposit section, find the deposit.
6. From the Received From dropdown, choose the customer from where the deposit came from.
7. From the Account dropdown, click on Accounts Receivable.
8. Once done, hit  Save and close.

When the deposit is updated already, apply it as a credit to the invoice.

1. Go back to the homepage screen.  
2. Select + New, then Receive payment.
3. From the Customer dropdown, choose the customer’s name.
4. In the Payment date field, enter the day you received the payment.
5. In the Outstanding Transactions section, click the invoice you need to mark as paid.
6. In the Credits section, select the deposit.
7. Once done, hit Save and close.
