What our customers say

Address errors were costing us $30,000 annually in address correction fees and causing delivery delays, which resulted in unnecessary expenses and unhappy customers. 

As a growing online retailer, we needed a solution to reduce these fees and improve customer satisfaction. Experian Data Quality did both; they've also provided a definite benefit to our online checkout experience.
