Product deduplication

Find the duplicates before they cost you twice.

Claro finds duplicate and near-duplicate listings across suppliers, channels and historical imports — the ones that look different but are not.

Why it matters

A duplicate SKU costs twice and reports wrong

Duplicates rarely look identical. Years of manual imports, supplier switches and channel migrations leave the same product under different SKUs, different descriptions, sometimes a different unit of measure — invisible to a simple exact-text de-dup rule, and expensive in ways that compound: split reviews, split inventory counts, a search ranking diluted across two listings instead of one. Claro clusters by real product identity rather than surface text, scores every proposed merge, and keeps the history so a merge can be checked or reversed rather than taken on faith.

The problem

Why exact-text deduplication misses most duplicates

Years of manual imports leave duplicate SKUs scattered across the catalog.

Near-duplicates — same product, different description — slip past simple de-dup rules.

Duplicate listings split reviews, inventory and search ranking.

FAQ

Product deduplication: common questions

What counts as a near-duplicate?

The same real product listed under different SKUs, descriptions, languages or units of measure — cases an exact-text rule will never catch because no two strings are identical.

Does Claro merge records automatically?

No. A merge is one of the highest blast-radius changes in a catalog, so it always goes to a named reviewer whatever the confidence score says.

Can a merge be undone?

Yes. The history of every merge is kept, including which records went in and which evidence supported it, so a merge can be reviewed or reversed rather than taken on faith.

How do you avoid merging genuine variants?

Variants are separated on the attributes that make them different — pack size, seal type, tolerance, finish. When those attributes are missing from the source, the cluster is flagged as uncertain rather than merged.

What does a duplicate actually cost us?

It splits inventory counts and reviews across two listings, dilutes search ranking between them, and can mean buying the same part twice from two suppliers at two prices.
