    What merchants praise

    “Paul is unbelievable. The app wasn't exactly what I needed (for now) but he took the time to send me a detailed e-mail to try to help me out. Just fantastic customer service and a sign that he is truly invested in this app. You don't see that much these days!”

    What merchants complain about

    “While it says "Find" and merge duplicate accounts, there is not yet any service with which to find them - it does not suggest Doppelganger accounts for merging, you need to already know which accounts you want to merge. I understand this is in development (and not easy!) so I look forward to testing the new app.”
