Does anyone use a monzo bank?

I understand you want to prevent duplicate payments from your Monzo bank feeds, @sez1. I'll share some insights with you and see if there have been any known problems reported.

There hasn't been any current research or investigation on the bank feed issue. It's likely that the issue is with your financial institution. In the meantime, I suggest removing the duplicate transactions by Excluding them.  This will keep the account in order. Here's how:

1. Select Bookkeeping, Click on Transactions, then choose Banking.
2. Go to the For Review tab.
3. Hit the checkbox of the transactions to eliminate.
4. Once done, click on Exclude.

If the issue continues, it'd be best to get in touch with your bank. This way, they can look into the issue further and provide you finest answer.

Once everything is back to normal, see this module about resolving any differences between QuickBooks and the bank balance: Reconcile an account in QuickBooks Online.

Fill me in so I can respond as soon as possible. I'm always ready to assist further with banking or QuickBooks specifically. Stay safe!
