We can utilize the +Add New feature in QuickBooks Online to add a Check as a Payment method, Rhett. I'm here to help in streamlining the processes of your payment.
If you currently only have Cash listed as a payment method, you can add a Check as another payment method. Here's how:
- Click + New, and select Receive payment.
- From the Customer dropdown, select the name of the customer.
- From the Payment method dropdown, click +Add new.
- Enter Check as the name of the New Payment method, then Save.

- Select the Check you added.
- In the Outstanding Transactions section, select the checkbox for the invoice you're recording the payment for.
- Select Save and close.

Once done, reconcile your accounts to ensure they match your bank and credit card statements.
