You can merge duplicate customer records to maintain database integrity and provide unified customer history, helping ensure accurate reporting and better customer service. This improves your retail operations by eliminating duplicate records, with properly executed customer merging typically enabling better customer data accuracy and more complete transaction history for relationship management.
Understanding customer merging involves recognizing duplicate detection methods, data consolidation processes, and transaction history preservation to help retail operators focus on the right data quality workflows, ensuring your retail strategy consistently drives better customer database accuracy and service quality outcomes.
Maintaining your data is essential to get the maximum business intelligence on your customer database. Duplicate customer accounts can exist for a number of reasons, including mistyped information, changed email addresses or mobile phone numbers and eCommerce integrations.
The Merge Customers feature in Retail Express makes it easy to merge duplicates into a single customer profile (their "master record"). We even merge transactions, including:
- Sales
- Returns
- Vouchers
- Loyalty
