I found an older transaction in QB - a payment was made to a vendor, but one of the 2 invoices was not for that vendor. can this be fixed?

Yes, you can fix this, but the approach depends on how you record the payment and whether you have reconciled the statement for that period.

If you haven't reconciled your record, you have a few options. For instance, for payments linked to a bank transaction, start by clicking Undo in the Action column to move it to the Pending tab, where you can edit and Match it with the vendor's invoice. However, you'll need to detach or unlink them if they're manual entries, then adjust the amounts so the payment matches the vendor invoice exactly to keep your records balanced.

Otherwise, you'll need to undo the reconciliation to make changes. With this, I recommend seeking assistance from your accountant to ensure the accuracy of your books and tax totals.

You can always count on me if you have any other questions about invoices.
