MergeSweep

Find and merge duplicate customer records in bulk, safely, with every match explained.

• Bulk detection. One scan finds gmail aliases, reformatted phone numbers, and name or address variants across your entire customer base.
• Explained, not black-box. Every match shows the exact fields that agree, graded into exact / high / medium / review confidence tiers.
• Safe merges. Shopify’s own merge engine combines orders, tags, and addresses server-side. Blockers are checked first and every merge is logged.

Install MergeSweep from the Shopify App Store to get started.
