Shopify Customer Migration
Your customer database is the asset that drives repeat revenue. Migrating it incorrectly breaks Klaviyo segmentation, disrupts loyalty program tiers, and produces email lists that no longer match your Shopify customer records. We migrate customer data to Shopify with the integrity your retention programs depend on.

The Problem
Customer records are not just contact information. They are the foundation for email segmentation, purchase history analysis, loyalty tier assignment, and win-back targeting.
A migration that treats customers as a CSV import loses the relationships between data that make those systems work.
A customer database migrated without regard to data relationships costs you in retention performance long after the migration is technically complete.
The Solution
We map customer data to Shopify's account structure before migration begins. That means order history linked to accounts, tags and segments carried over, and email lists synchronized with the migrated records.
Loyalty program migrations require coordination with your loyalty platform. We handle the data handoff so tier status and point balances arrive correctly in the new environment.
What's Included
Revenue Impact
Email Revenue
Klaviyo's highest-performing flows, win-back sequences, and VIP segments depend on accurate purchase history and customer tags. A migration that loses this data degrades your email program from day one.
Retention Rate
Customers who lose their loyalty points or tier status after a migration churn at higher rates. Preserving loyalty data keeps retention programs intact without requiring a customer to re-earn their status.
Customer LTV
Order history attached to customer accounts powers LTV calculations, repeat purchase rate analysis, and reorder targeting. Without it, you are flying blind on your most valuable cohorts.
Compliance Risk
Sending marketing emails to customers whose consent status was not preserved during migration creates regulatory exposure in EU and UK markets. We map consent flags explicitly.
How We Work
We export and analyze your customer records: field structure, order associations, tag taxonomy, and consent data. We identify mapping issues before migration begins.
We document how every customer data field maps to Shopify's account structure, including tags, metafields, and consent flags.
We migrate customer records and link order history to accounts in Shopify. Tags and segment data are mapped to Shopify customer attributes.
We synchronize migrated customer data with Klaviyo or your email platform, preserving list membership and historical segment data.
We validate record counts and field completeness against the source export, then set up the customer account activation flow so customers can access their accounts.
Tech Stack
Why Others Fall Short
Customer migration is almost always treated as the last step in a platform migration, done quickly and without the data relationship mapping it requires. The result shows up weeks later when email revenue drops and loyalty programs stop working.
We treat customer data migration as a retention infrastructure project, not a spreadsheet import.
