Merge Customers - Feedback and questions

Shopify Discussion

Topic summary

Shopify introduced a customer profile merge feature, allowing merchants to consolidate duplicate accounts by matching attributes like name, email, or phone number. The merge process is accessed through the Customers page under “Customer Data” section.

Initial Reception & Basic Functionality:

  • Users successfully merged profiles with typos or duplicate emails
  • Orders and information transfer to the merged profile
  • One caveat: the email from the “wrong” profile sometimes becomes the default, requiring manual correction

Major Limitations Reported:

  • Cannot merge customers with:
    • Gift cards (active, inactive, or expired) — later resolved
    • Discounts applied (including third-party reward/loyalty apps) — being addressed
    • B2B customer profiles
    • Subscription contracts
    • Metafields (including those from partner apps)
    • Data redaction requests in progress

Technical Issues:

  • Some merged profiles show zero statistics (order count, average value) despite orders appearing in timeline
  • Metafield errors occur even when merchants claim not to use them (often from hidden app-generated fields)
  • Generic “Customer merge failed” errors without explanation

Feature Requests:

  • Automated duplicate detection tool to identify potential matches
  • Ability to sort customers by last/first name
  • Better handling of discount-related blocks

Access Note:
Requires specific “Merge customers” permission enabled by store administrator for staff accounts.

We just tried this with one of our customers and it worked! It was one of our customers who made an order with a typo in their email. We merged the wrong customer profile to the right one and the information and orders merged with it.

We had to double check the email though. We went to the correct customer profile and merged the wrong one to it, and we weren’t able to review the information to see which email would be the one it would default to. The wrong customer email is the one that defaulted (which was odd to me considering we were merging to the correct customer profile). It was an easy fix to update the email on the merged profile, just something to be cautious of moving forward.

Thank you Shopify staff for fixing this.
