Two trades where generic listing tools give up.
Fine jewellery and auto salvage both have data no horizontal tool models — certificates and 4C grades, VINs and assemblies. CaratList and Salvage OS are built on MergeKart’s core, in the trade’s own vocabulary.

verticals treated as first-class products, not add-ons
A ring and an alternator are not just products.
Jewellery carries a document
The certificate is the product’s truth. Retyping 4C data into a listing is how errors and returns start.
Salvage carries a parent
Every part traces to a VIN. Lose that link and you cannot prove fitment, provenance or recovery.
Neither fits a generic field set
Hallmarks, lab reports, assemblies, bins, scrap weight — a horizontal tool makes you fake all of it in custom fields.
Before and after
A vertical seller’s week
The same work, measured twice — today’s numbers against the same catalogue running on MergeKart.
Six tools, five hubs, nothing talking to anything else.
Every job feeds one record, and the marketplaces follow it.

The same core, in the trade’s language.
Both verticals reuse MergeKart’s catalogue, pricing and channel layer — only the data model and vocabulary change.

“Nothing horizontal models a certificate or a VIN. We stopped bending a generic tool and started using one that knows the trade.”

Because their listing data is not a generic template. A diamond is described by a lab report and a salvage part by a donor vehicle — neither fits the flat attribute model a general listing tool assumes.
Yes. They sit on the same catalogue, so OmniList still publishes and syncs, OpsPilot still runs orders, and PriceLens still reprices against the market.
It reads a lab report once and attaches carat, colour, clarity and cut to the SKU permanently, so every listing on every channel inherits certificate-accurate data.
Salvage OS is still in development and not yet released. CaratList is available today for fine jewellery catalogues.
