Hello there, @SBoulia.
Thank you for visiting the QuickBooks Community. I'll share details on how voiding a check applied to invoices works in QuickBooks Desktop (QBDT).
Voiding a check applied to invoices will affect the financial statement and the invoices will mark as unpaid. We can create a separate invoice payment and create a vendor credit as payment for an open bill.
Here's how to set credits:
- Choose Vendors at the top menu bar.
- Select Pay Bills.
- Choose the bill that you wish to be paid.
- Tap the Set Credits button at the bottom to apply credits.
- Once done, hit on Pay Selected Bills.
You may also read through the following links for more insights about handling credits:
Additionally, you can read through this article in case you need help customizing vendor reports to pull up a specific statement you're looking for: Customize vendor reports.
