Enterprise customer data is severely fragmented across Salesforce CRM, Shopify E-Commerce, Zendesk Support, and In-Store Point-of-Sale (POS) systems. A single customer currently appears as up to four unlinked records due to variations in email addresses, phone formatting, and name abbreviations. This fragmentation inflates customer counts by 32%, distorts Customer Lifetime Value (LTV) metrics, and causes VIP customers to receive generic marketing promotions. Engineering must build an identity resolution graph and golden record survivorship engine to synthesize a unified Customer 360 profile.
