Commerce and retail
Each morning, seller by seller: the gap between your price and each market's selling price (tax aligned), what moved since yesterday, what disappeared.
What is not in your systems
You know your inventory. Cost, listing price, days on hand — all internal.
What is not internal is where that inventory stands in the world this morning. And nobody publishes it.
What arrives every morning
| Your price against each market | The gap between your own price and each market's selling price, tax aligned |
| What moved since yesterday | What rose, what fell, what appeared |
| What disappeared | A listing leaving a results page is the closest public proxy for a sale |
| The gap by country | What the same product fetches in each market |
Nobody stores "what changed since yesterday", so it cannot be bought later. You only ever have it from the day you start.
Where the decision changes
| Problem | What you get |
|---|---|
| No defensible basis for pricing | Per-product gap between each market and your own price, every morning, in a form that survives a meeting |
| Don't know what is worth exporting | Only the wide gaps that are also high confidence |
| Buying is instinct | The rate trend and the record of disappeared listings, as material for the decision |
| Erosion noticed too late | Alerts only on day-over-day moves past a threshold |
| Different prices per marketplace | Each venue collected separately |
| Parallel imports are invisible | Your own products, and their prices, on overseas venues |
Four habits that keep a comparison like for like
Taxes aligned before comparing. Tax-inclusive and tax-exclusive prices are settled at collection, and comparisons read the tax-exclusive column. A market without consumption tax and a Japanese price that includes it are compared on the same basis.
Accessories kept apart from the product. An accessory is counted on its own and never enters the price gap of the product it fits.
Model numbers read to the last suffix. A single trailing character makes a different product, so premium and standard variants are compared separately.
Absence confirmed twice. A listing is recorded as gone only after two reads in a row without it. A listing that merely moved down the page is not counted as gone.
What it fits
Anything with a model or part number, listed on more than one venue, priced differently by country or channel. New or pre-owned.
Appliances, cameras, jewellery, instruments, bicycles, tools, PC peripherals, automotive parts, collectables, branded apparel, cosmetics, supplements.
Change the category and the only thing that changes is the list of sources.
