How do you apply a check payment to an invoice?

Hi @rachel5,

Welcome to the Community. I can help you with applying a check payment to an invoice.

It's always a good feeling when you see a customer payment. You can record the check payment with the following steps:

1. Click the Plus sign and select Receive Payment.
2. Choose the name of the customer, date of payment, and Check for the payment method. 
3. Enter the amount of the payment and select the invoice to apply the payment to. 
4. Click Save.

I'm including a brief video to serve as a visual guide:

For additional information on this process, such as how to use Undeposited Funds, I recommend the following articles:

• How to Record a Customer Payment
• Receive Payments in QuickBooks

That should take care of it. I believe that you'll have the check payment applied to the invoice in just a few clicks. 

Please don't hesitate to let me know if I can be of further assistance. Wishing you well.
