Merge duplicate accounts and get a better view of the actual Customer Lifetime Value.

Also useful for linking accounts from the same company together to determine the Life Time Value of a client company.

App never worked and would not load in admin. reached out to support and submitted their requested info but never heard anything back. My attempts to follow up with support when I heard nothing were met with crickets. Honestly don't bother.

Does NOT merge the customer. "links" them which does nothing on a search. You still have both customers

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.

I used this app to help me merge orders to the main customer profiles and delete the duplicate customer profiles. It was all part of a clean-up project to rid our customer list of duplicates. I ran into a problem with one profile. An order had some how been tagged to the main customer profile and duplicate customer profile. I reached out to Doopelganger support and within the hour Paul responded with a suggestion on how to correct the problem. I followed his suggestion and voila (like magic), Doopelganger was able to merge the order to the main customer profile and delete the duplicate. Doopelganger works like a champ and I couldn't be happier with the results. Thank you Paul!

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!

I've just started using Doppleganger to help sort through the absurd number of duplicate accounts my store has. Paul has been very responsive to my questions, going to far as to make a video to walk me through adding an additional account to a merged group of accounts and how to unmerge a group of linked accounts - both of which are very easy to do.

Paul has been of great help. We use Doppelganger to fix customer issues when creating accounts with multiple email addresses, primarily when using our social login feature. We're glad to be doing business with you.

Very easy to connect customers with multiple accounts. Like the new updates as well. Had an issue with app opening and working this week, sent an email to Paul and he immediately jumped in and worked with me until the issue was found and corrected. He stayed in touch and updated me just like he said he would. Thank you!

The app is brand new, thus no reviews yet it seems. The developer helped to fix issues asap and the app works perfectly for searching and merging duplicate customer data.
