Why it matters
This is the only leak with no alert attached to it, because nothing went wrong — nothing happened at all. A retailer stocks your category, ranks for the searches you want, and sells someone else's product to the shopper who was looking for yours. There is no complaint, no bad review and no number in your sales data. Just a shelf working for somebody else.
Coverage is scoped per client. We report the shelves that carry your category, and which of your references are missing from them.
How the revenue leaks
Every other problem on this site announces itself. This one is silent, which is exactly why it persists for years.
Closing a coverage gap is the one lever here that adds new demand rather than recovering existing demand.
Diagram: the four stages by which this problem turns into lost revenue.
What we report
Three different problems that a single coverage number would hide.
The retailer stocks the category and carries none of your references.
A buyer conversation, not a supply problem.
The page exists and nobody can order from it.
Kept separate, because this one is a supply problem.
A retailer you sell through that we are not reading.
Added on request, in days, rather than queued for a release.
In the platform
Filled cells are references we can find. The empty ones are the conversation.

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
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.
Why one row matters
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 costsThe size of the prize
10–30%+
revenue our clients can recover
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 foundIndicative 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
Every finding starts as a row in the same scan. What changes is the question you bring to it.

What you get
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.
