I have entered an expense yesterday, but when the bank feed come is it does not find the match but instead wants to add it thus giving me a duplicate in the credit card

Thanks for posting to the Community, @geoff50k.

The first thing to check is on the original expense you created. Is the bank it is paid out of showing correctly on the expense and do the amount and date match what shows in the banking screen? If not amend them so they are showing as the same as the banking transaction. If they do show correctly go back to banking screen and click on the line of the transaction you should see that part expand and a find the match option appear. In the search boxes select the specific supplier and look for that transaction in the options that show up.

If you are unable to find it and this transaction prompts you to add  duplicate expense, you can exclude it to keep your accounts accurate and to prevent this from showing in the Register.

Let me show you how:

1. Go to Banking and then select the For Review tab.
2. Check the box for the expense that prompts you to create a duplicate transaction.
3. Click Batch actions and then select Exclude selected.
   

The transaction that you have excluded will go to the Excluded tab where you can offset the transaction.
