Hello,

I inadvertently entered an invoice twice. One is paid and the other is pending payment. How do I reverse the open invoice so that the vendor doesn't get paid twice?

Thank you

To reverse a posted open invoice in Dynamics 365 Finance and Operations to ensure the vendor doesn’t get paid twice.

Option 1: Cancel the open invoice through a credit note

Navigate to the Vendor Invoice Journal:

Go to Accounts payable > Invoices > Invoice journal.

Identify the Duplicate Invoice:

Search for the duplicate invoice that is still pending payment.

Create a Credit Note:

Create a new journal entry by clicking New.

Select the same vendor and reference the duplicate invoice number in the description.

Enter a negative invoice amount (to reverse the amount).

Post the Credit Note:

Once the credit note is entered, validate the journal and post it.

Verify in Vendor Transactions:

Go to Accounts payable > Vendors > All vendors.

Select the vendor and navigate to the Transactions section.

Confirm the original invoice and credit note are offset against each other.

Option 2: Void the Open Invoice (if allowed)

If the invoice has not been settled or partially paid, you may be able to void it.

Navigate to the Invoice:

Go to Accounts payable > Invoices > Open vendor invoices.

Locate the duplicate open invoice.

Void the Invoice:

Check if the system allows voiding by selecting the invoice and clicking on Cancel or Void (depending on your organization’s setup).

If the option is unavailable, you’ll need to use Option 1.

Option 3: Adjust Payment Proposals

If the invoice is included in a payment proposal, ensure it’s excluded from payment:

Go to Payment Journal:

Navigate to Accounts payable > Payments > Payment journal.

Locate the payment proposal including the duplicate invoice.

Exclude the Duplicate Invoice:

Edit the payment proposal and manually remove the duplicate invoice line.

Revalidate and post the payment proposal.

Follow Up with Credit Note (Optional):

If voiding is not possible, use a credit note to offset the open invoice.

Final Steps:

Communicate with the Vendor: Notify the vendor that the duplicate invoice has been voided or offset to prevent confusion.

Run a Vendor Statement: Validate that the vendor ledger shows the correct balances.
