Platform · Catalog

Every product, priced across every retailer.

Your catalogue as the market actually prices it. One row per product, showing the price range across all retailers, how many carry it, how many have it orderable, and how far apart the cheapest and most expensive offers sit.

The Merqi Catalog screen: every product with its price range and the retailers carrying it

The screen

One row per product, all retailers consolidated.

Lowest, median and highest price across the market, the number of retailers carrying the product, and the dispersion between the cheapest and most expensive seller. Sorting by dispersion surfaces supply problems before any alert is generated, and frequently before anyone in the business has been told. Catalog is the screen a supply team opens when the question is where price integrity has already been lost.

The primary signal

Dispersion, measured against each product's own floor.

Absolute currency is the wrong axis for comparison: a low-cost accessory and a premium product cannot share one. Expressed as a multiple of its own cheapest offer, every product becomes directly comparable, and the widest ratios identify where pricing control has already been lost. Sorting the catalogue this way is the most useful single action on the screen.

Five products from one client's dispersion export, 28 August 2026. The same file recorded 157 open dispersion items on that retailer alone.

Chart: five references plotted as a multiple of their own cheapest seller, the widest spreading beyond two to one.

Fields and columns

The catalogue table.

Sortable on every column, and identical in the export.

Column Contents Purpose
Product Your SKU and product name Your naming, not ours
Low / median / high The market price range Three figures rather than an average
Dispersion Cheapest against most expensive The earliest supply signal
Retailers carrying Retailers stocking the product Distribution breadth
Retailers orderable Retailers where it can be bought Breadth that converts
Listings matched Every page tied to the product Including pages you did not create

Matching runs on product title and identifier. Anything below the confidence threshold is held on the Candidates screen for review rather than merged into a figure a team would then have to trust.

The decisions it supports

What supply and commercial teams come here to establish.

01

Where has pricing already moved?

Dispersion is the earliest observable sign of stock reaching the market outside your intended terms. A product selling at both ends of a wide range is being supplied to someone at a price you did not set.

02

Where is distribution thin?

Retailers carrying a product against retailers with it orderable. Twelve carrying and four orderable is a distribution problem, not a pricing one.

03

Which listings did we not create?

Every page matched to a product, including duplicate listings created on your products by sellers with no supply relationship.

On each row

What each row establishes.

Catalog is where a pricing problem is identified. Optimisation is where it is attributed to a seller.

Low, median and high

The full price range across every seller and every retailer carrying the product.

Tabular figures, so a column of prices reads as a column.

Dispersion

The distance between the cheapest and most expensive offer — the clearest early signal of uncontrolled supply.

A product at zero is under control; one spreading two to one is not.

Retailer count

How many retailers stock the product, and how many have it orderable at capture.

Both counts matter, and they are frequently different.

Matched listings

Every page tied to the product, including duplicates created by third parties.

Uncertain matches wait on Candidates rather than merging silently.

Seller count

How many distinct sellers offer the product, and how many of those you supply directly.

Fourteen sellers against four supply accounts describes a leak.

Change since last scan

Whether the range widened or narrowed, and which end of it moved.

A falling floor with a static ceiling is one seller, not market movement.

In practice

Where a supply review starts.

Sort by dispersion

The widest ranges identify where pricing control has already been lost, before any alert is generated.

Compare carried against orderable

A product stocked by twelve retailers and orderable at four is a distribution problem rather than a pricing one.

Identify listings you did not create

A product with more listings than retailers usually indicates a duplicate page created by a third party.

Somebody else is setting your price on six retailers.

Merqi is the enterprise platform that tracks who sells your products, who holds the buy box, and at what price — across the retailers and marketplaces you actually sell through.

Retailers monitored

The problem

Right now, a seller you never appointed a reseller with your stock a marketplace trader an account you cannot name somebody undercutting you is costing you revenue and losing you customers.

They win the sale on a listing you built, to a customer who believes they bought from you. If that order arrives late, damaged or grey-market, you lose a customer and the revenue both — and neither ever appeared in your channel to begin with.

Undercutting is only the visible half. The rest of the damage never announces itself.

And it is never just one thing

Seven ways your distribution leaks.

A lost buy box is the one you can see. Merqi reads all seven on the same scan, so the damage you have not noticed shows up beside the damage you have.

{{ l.body }}

What it costs you

Why one row matters

Four in five sales never see a second seller.

The featured offer is not a ranking, it is the default. The other sellers sit behind a link most shoppers never open, and on mobile they are not on screen at all. So when someone else holds the box on your listing, the page still converts — for them, on your product, at a price you did not set.

What a lost box actually costs

The size of the prize

10–30%+

revenue our clients can recover

The margin is already yours. Somebody else is taking it.

Every buy box lost to an unauthorised seller is a sale made at a price you did not set, on a listing you paid to build. Recovering those listings, closing the coverage gaps and holding distributors to their terms is where the range above comes from.

See what one scan cycle found

Indicative range. What Merqi recovers for your catalogue depends on how many of your listings are contested and how far price has drifted — the first report tells you which.

How it works

Three workflows, one ledger.

Every finding starts as a row in the same scan. What changes is the question you bring to it.
