My friend paid the same invoice twice. It cost him weeks of awkward emails to get the money back. So I built him a duplicate checker in n8n

Hey @Benjamin_Behrens, thanks for the kind words! That’s actually a great idea to add to the flow later. My friend has been testing it for almost three weeks now, and so far, not a single error has occurred. That said, the extraction tool I’m using does allow building error logs around the extraction process, so if an extraction ever fails, the node returns an error code.
