Any broker can tell you they have good judgement. It is not a claim you can check, which is why everyone makes it.
So instead: here is the mechanism. What it watches, what it computes, how far the coverage actually extends, and — the part nobody publishes — what it does not do.
The figures on this page were taken from our production database on 26 August 2026. They will drift; the shape will not.
What the engine watches
An automated crawler runs continuously against 16 active marketplaces — liquidation houses, overstock platforms, insolvency and closeout venues — whose listings originate across 13 source countries in Europe and North America.
New lots are picked up in hours. That matters more than it sounds: the useful life of a good lot is short, and by the time a broker newsletter reaches an inbox the lots worth having have usually been taken. Coverage across many venues at once is the thing a single buyer cannot replicate by hand, in any number of hours.
We do not publish which venues those are. That is the one piece of genuine commercial information we hold, and a page listing our sources would be a map for anyone who wanted to skip us. What we will say is the shape: multiple countries, multiple languages, multiple auction and fixed-price formats.
Currently tracked: 58,259 lots.
What happens to a lot after it is found
Every lot that enters the catalogue goes through the same pipeline. There is no manual shortlist at this stage — a human looking at 58,000 lots is not a process, it is a bottleneck.
1. Identification
The listing is parsed into structured fields: category, quantity, condition where stated, location, currency, and — where the listing carries one — a product identifier. A lot with identifiable products can be priced. A lot described only in prose can be estimated by category and no more, and it is scored accordingly.
2. Pricing against live market comparables
This is the step that decides everything downstream. Rather than trusting the retail figure a seller states, we look up what the goods actually sell for right now, in the market a buyer would sell them into.
The comparables come from live consumer marketplace data — Amazon price history and eBay realised and current prices, taken as medians rather than best cases, because a single optimistic listing is not a market. From that we derive an estimated sell-through price for the lot.
Coverage: 56,362 of 58,259 lots — 96.7% — carry a computed sell-price estimate. The remainder are lots too vaguely described to price, and they stay that way rather than being given a number that would look like knowledge.
3. Landed cost and margin
The sell-price estimate is only half of a decision. Against it we set the cost of actually having the goods: the lot price, freight for the volume and route, handling, and duty and clearance where the lot crosses a border.
The output is a margin figure and a score. The same 96.7% of lots carry both. A lot whose margin does not survive its own freight is not a bargain, and a great many lots in this market are exactly that — which is why most of what the engine finds never reaches anyone.
4. The seller record
Every lot is traced back to a seller we hold a record on: 10,347 seller records, with domain, country, category profile and website-liveness checks. 7,822 have had their website checked; 6,816 are currently live. A seller whose site has gone dark is a fact worth having before a transfer, not after.
What we do not do — stated plainly
A page like this is worth nothing if it only lists strengths, so here are the limits, in the order they matter.
We do not independently verify sellers. Our seller records are built from marketplace and directory data and automated checks — a company registry filing is not pulled, an address is not visited, references are not called. The record tells you who a seller is on paper and whether their operation still exists online. It does not tell you they are trustworthy. Where a lot is large enough that this matters, verification is a separate piece of work, and our guide to doing it is the same protocol we would follow.
We do not inspect goods before offering them. Nobody at SITONAI opens a pallet before it is offered. Condition on our offers is the seller's stated condition, read critically and scored — not our own assessment. Where a lot is untested returns, we say untested returns.
A price estimate is an estimate. It is built from market data, not from a buyer's own sales history, and yours will differ. Our number is a filter for deciding which lots are worth your attention. It is not a forecast of your margin, and we will not present it as one.
The manifest is still the seller's document. We read it, price it and score it. We do not audit it, because it cannot be audited from outside — see how to read one for what that means for a buyer.
We are a young company. The engine and the catalogue are real and the numbers on this page come out of a live database. A long trading record is not something we can claim yet, and a page that implied otherwise would fail its own test.
What actually reaches you
Of everything above, one thing is the product: the rejection rate. The engine's value is not that it finds lots — anyone can find lots — it is that it throws almost all of them away on evidence, before a person spends any time on them.
What is left gets matched against what you told us you buy, and sent to you with the quantity, our price, the retail comparison and the photos. You accept, counter, or pass. Nothing is binding until you accept, and there is no obligation on any offer.
FAQ
How does SITONAI decide what a lot is worth?
Not from the seller's stated retail figure. Where a lot's contents are identifiable, we look up live market prices for those goods — Amazon price history and eBay realised prices, taken as medians — to derive an estimated sell-through price, then set the landed cost against it: lot price, freight for the route, handling, and duty and clearance where the lot crosses a border. That produces a margin figure and a score. As of 26 August 2026, 56,362 of 58,259 tracked lots carry that computation.
Which marketplaces does SITONAI source from?
We do not publish the list. Sixteen active venues across thirteen source countries in Europe and North America, spanning liquidation houses, overstock platforms and insolvency and closeout sales. The specific venues are the one piece of genuinely commercial information the business holds — publishing them would be publishing the reason to use us.
Does SITONAI inspect the goods?
No, and no sourcing intermediary at this scale does. Condition on our offers is the seller's stated condition, read critically and scored against the rest of the lot's data — not our own physical assessment. Where a lot is untested customer returns, our offer says untested customer returns.
Are SITONAI's sellers verified?
They are catalogued, not verified. We hold 10,347 seller records with domain, country, category profile and automated website-liveness checks — 7,822 checked, 6,816 currently live. That is a record of who a seller is on paper and whether their operation still exists online. It is not a due-diligence sign-off, and we will not describe it as one.
What does it cost to receive offers?
Nothing. Telling us what you buy takes about ten minutes, receiving matched offers costs nothing, and no offer is binding until you accept it in the client portal.
