Your option is a great idea, jeffreyk28.
Let me provide another workaround so you can apply the credit memo to the correct job
You can enter the total invoice amount in the Payment Amount field on the Customer Payment page instead of $10,000. Then, record the overpayment as a credit memo and make sure to select the correct job.
The next time you record a payment, you can then apply the credit memo to the appropriate job.
However, since you've already recorded the payment, your next step is to transfer the credit to the desired job. Check out this link for instructions and detailed steps: Move credit memos.
Let me know if you need anything else aside from applying credit memos. Just tag my name, and I'm always right here to help you.
