QuickBooks doesn’t allow negative bills by design, but there is a standard workaround to correct the amount. You can create a Vendor Credit to record the reduction in what you owe the vendor, and then apply that credit against a future bill. To do this, go to + New or + Create > Vendor Credit, then complete the required details.
If the adjustment is actually a refund or a reversal tied to a specific expense account, you may also record it through a journal entry, depending on your firm’s workflow. For accurate guidance on debit and credit treatment, please consult a professional accountant.
I’ll keep this thread open in case you have any updates or need anything else.
