    Customer Data Unification

    Fashion & Apparel Brand

    Fashion & Apparel

    The challenge

    The company operated across Shopify, Sitoo POS, Brightpearl, and Klaviyo with no shared customer record. Marketing campaigns hit duplicates, personalization was impossible, and customer service had no unified history.

    What we built

    • Customer record sync across all four systems with email-as-unique-key deduplication
    • Multi-currency order handling via XE.com live exchange rate integration
    • Klaviyo customer and purchase event sync ensuring segments reflect live behavior
    • In-store Sitoo POS purchase data feeding back into the unified customer profile

    The outcome

    • Single customer record shared across all four systems
    • Marketing campaigns built on complete cross-channel purchase history
    • Customer service team has full view regardless of purchase channel
