Hello there, @Angel11-72.

Thank you for the additional information you've provided. Allow me to clarify some insights when depositing partial payment.

We deposit the $300 or partial amount to remove the Undeposited Funds (UF) and post in the bank. Then, the remaining $100 payment will remain in the UF suggested by my colleague @MaryLurleenM. 

To ensure that we're able to provide you the exact solution, it would be great if you can add some information on how you record the payment in the Undeposited Funds.

I've added this article that can guide you more about Undeposited Funds in QuickBooks Onlline.
