Merqi

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.

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.

The buy box, taken

Someone else wins the add-to-cart on your own listing. Their price, their customer, your product — and the sale never appears in your channel data, because as far as the retailer is concerned it was never yours to lose.

What it costs you

Sellers you never appointed

Trading on stock you did not knowingly supply, with no warranty and nothing to protect.

What it costs you

Shelves you are absent from

Retailers carrying your category and not your products. Revenue you never had a chance at.

What it costs you

Listings you never created

Duplicate pages built on your references, splitting your reviews and your ranking in half.

What it costs you

Unbuyable, not delisted

Live pages nobody can order from. The traffic still arrives and converts for nobody.

What it costs you

Advertised price off policy

Where price sits against your policy, per seller, per retailer — and the lever you have in that market.

What it costs you

Commitments never delivered

You funded a price the shopper never saw. Late starts, skipped retailers, and a mechanic written off as a failure.

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

Chart: about four in five marketplace sales go through the featured offer; the remainder reach shoppers who open the other-sellers list.

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.

The optimisation view in Merqi: contested listings with the seller holding each buy box and their price

Find who took the box

  • Every listing where another seller holds the buy box
  • The winning price, against your reference price
  • The seller named as the shopper sees them, not an account ID
Merqi Channels screen for one retailer: references carried, price position against the market median, stock reliability and buy-box win rate

Monitor your distributors

  • One distributor's shelf on its own, not a catalogue-wide average
  • Price position, stock reliability and buy-box win, read daily
  • Dated rows you can forward without editing them

Close the coverage gap

  • Retailers carrying your category but not your products
  • Listed-but-unbuyable rows kept separate from absent ones
  • New retailer coverage added on request, in days

What you get Research Exports Start

What you get

Everything happening on other people's shelves.

The first two are what most brands come for. The rest is what they did not know they were missing — and the platform they read it all in.

See everything the platform reads

Who is selling

Every third-party seller on your references, named as the shopper sees them.

Store names, not account IDs — so the name in the report is the name you can raise with your distributor.

Who holds the buy box

Buy-box attribution on every listing we can read, with the winning price against your reference.

Standing is read from the captured ownership timeline, never inferred from price.

Where you are absent

Shelves that carry your category but not your products.

Kept apart from out-of-stock rows — two problems, two fixes.

What they charge

The gap between your reference and what a shopper actually pays.

Reported as a percentage, dated, per listing.

All of it, in one place

A dashboard, catalogue, per-retailer channels, the optimisation view and a live alert queue — logged into daily.

The monthly report and the CSV come out of it. They are an output, not the product.

On one client account, Merqi reads 4,196 listings across 78 active retailers every day and names every seller holding a box that should have been theirs. Catalogues are unlimited — this is one brand’s shelf, not our ceiling.

Paris rooftops at dusk Case study How H.Koenig took back control of their own shelves A Paris appliance brand selling through 78 retailers could not say who held the box or where price had drifted. We built the infrastructure with their commercial and supply teams until it could. Read the case study Pallet racking in a distribution warehouse Research paper Unauthorised sellers: what they actually cost, and how to remove them The revenue figure most brands quote double-counts.
