Nightly scan, confidence-scored clusters, and safe bulk merge through Shopify's own customerMerge — no spreadsheets, no guesswork.
Email and phone exact matches, plus fuzzy name + address — every cluster ranked so you know which ones are safe to automate and which need a human look.
Merge every high-confidence group in one click. Clusters with conflicting subscription status or defaults are skipped, never merged on a guess.
Every merge — who requested it, what Shopify returned, when — is recorded permanently. customerMerge has no undo, so the record does.
Nothing merges without a decision. See every duplicate group in your admin before anything changes, on every plan.
A standing summary of new duplicate groups lands in your inbox — you don't have to remember to open the app to know your customer list is drifting.
Email, phone, and address are only ever used for matching. shop/redact and customers/redact erase everything tied to a store or a single customer, automatically.
Every night, Mergehouse reads your customer list and matches on email, phone, and name + address.
See every duplicate group ranked by confidence, right in your Shopify admin.
Merge one at a time, or all high-confidence groups in a single click — powered by Shopify's customerMerge, so order history stays intact.

No — Shopify's customerMerge has no reverse operation, by design. That's exactly why every cluster is scored, conflicting clusters are skipped automatically, and nothing merges without you seeing it first.
Only what matching needs: email, phone, name, and shipping address, normalized for comparison. No order or payment data. Full detail in our Privacy Policy.
Every night, automatically, via Shopify's bulk export API — no manual export, no CSV.
Yes — the nightly scan uses Shopify's asynchronous bulk operations API, built for full-catalog exports rather than paginated calls.
