In the event I am not the only person who ended up with 800 duplicate barcodes, I want to save hours of your time. Download the Duplicate Finder app. Shopify Chat support will state the only solution is manually deleting each duplicate. I accepted the Chat guidance that I must do it manually. However, that solution was not acceptable to the business owner’s son. Duplicate Finder has been a breeze to use.
Thank you for sharing that suggestion @TresaM ! I’ll suggest that app as an alternate solution to our Quickbooks Migration team so they can recommend it as well.
