Paid twice - Credit Note?

HI,

We have paid a vendor twice. The invoice went to the system twice. Interesting nonetheless as you can only enter an invoice number in the system once.

What would be the best way to corret that in the system. Make a journal, enter a dummy credit note? Feel free to give any ideas.

The vendor is aware of that and we will set up the excess against other future invoices

Enter a dummy Credit Note ( using the duplicated invoice as reference ).

Make sure to account for any VAT so it is not claimed twice.

On a side note, you should check all accounts against supplier's statements before making payments. This should eliminate the risk of paying an invoice twice.
