Recording a transaction that shouldnt have been made

Hi @Xcc3 

Thanks for writing here.

In terms of bookkeeping journal entries posted by anyone except your accountant or CPA, it will be a mess.

If you have done already it electronically, then your supplier needs to refund it first, then an adjustment may come.
If you have done it already in the previous month & reconciling it this month.
Then undo the payment.
Made the partial payment for that transaction

Record the supplier refund to the same Chart of accounts.

If you really wanted to make a journal entry for reversal,
Then do the following.

"Bank account-Debit"
"Supplier Account- Credit

remember you must have the reversal transaction in your banking panel.

For further assistance from me, check my bio.

All the best
