About MergeKart
MergeKart is multi-channel listing and marketplace management software. We build the layer between a seller's catalogue and the marketplaces they sell on.
Why ten products rather than one
A seller who needs repricing does not necessarily need image editing, and charging them for both is how platforms become bloated. MergeKart is one platform with ten products you switch on separately. Unsubscribed products stay visible in the app, dimmed, so you always see what you could turn on next rather than discovering it in a sales call.
One catalogue underneath all of it
Every product reads and writes the same product record. Turning one on never means re-entering your catalogue, and a sale on one channel decrements every other in the same second — which is the mechanism that removes overselling, not a setting you configure.
Built with operators, not for them
The vertical products exist because generic tooling failed specific trades. CaratList came from watching jewellery sellers retype certificate data; Salvage OS came from yards tracking parts on paper. Both were built alongside people doing the work.
What we will and will not do
We show you the gap instead of filling it
Anything a machine cannot determine is pinned and blocks publish. No invented GTINs, no guessed grades.
AI output is always marked and editable
Machine-read values are visibly distinct from what you entered, for as long as the listing exists.
Never a charge per marketplace
Unlimited channels on every plan. Adding a channel should not be a commercial decision.
Your data leaves in files you can use
Catalogue, images, certificates and mapping templates export in open formats.
Verticals are built with operators
CaratList and Salvage OS were both specified on a yard floor and a jeweller’s bench.

A 30-minute session with your SKUs and your channels — you keep whatever we set up.
No card for the first 14 days · your catalogue, not a sandbox
