Resolving duplicate client files involves systematically identifying and merging redundant records in databases or systems, preserving complete information while eliminating redundancy. This differs from simple deletion by prioritizing data integrity through defined rules and validation rather than just removing entries. The process typically uses matching logic on identifiers like names or emails, then establishes merge protocols.

Common implementations include CRM platforms like Salesforce applying deduplication tools for marketing contacts and financial institutions merging customer profiles across banking systems to prevent fragmented views. Healthcare organizations often implement EHR merges with strict audit trails when duplicate patient records occur, ensuring history remains intact.

Best practices enhance data accuracy, operational efficiency, and compliance. However, complexities arise in scaling across large datasets and establishing universal matching rules, requiring ongoing refinement. Ethical handling of merged data, particularly under regulations like HIPAA or GDPR, demands transparency and documented processes. Future automation using AI may improve match accuracy while reducing manual effort.
