The Basics

What is product matching?

Product matching pairs each product in your catalog with the same product on every competitor site, marketplace, and channel, so every price you see is a true comparison.

It's the invisible foundation of price intelligence. Every alert, report, and repricing decision is built on top of a match.

Get the matches right and everything downstream simply works: alerts you trust, reports you forward, repricing you let run.

Altosight uses barcodes and identifiers whenever they exist, they make strong matches stronger. And when sellers don't publish them, names, images, and attributes carry the match instead.

Every match is scored for confidence, edge cases are flagged for a closer look, and the final say is always yours: accept, replace, or remove any match, feeding your competitor price monitoring from day one.

Key distinction

Accuracy you can actually see. Every match carries a confidence score, and you hold the final say: accept, replace, or remove. So the data your repricer runs on is data you've chosen to trust.

01
Catalog in, as it is
Barcodes for some products, none for others: the file you have is enough.
02
AI scores every candidate
Names, images, and attributes compared across every seller's listings.
03
Confidence scored, edge cases flagged
Strong pairs go live. Uncertain ones are surfaced for a closer look, never assumed.
04
Matches go live
Verified pairs feed monitoring, alerts, reports, and repricing.
05
You stay in control
Accept, replace, or remove any match in seconds. Add new listings anytime.
Why It Matters

Matching quality decides everything built on it

The match is the foundation under every price you'll act on. Here's what strong matching changes.

01 Foundation first

Decisions are only as good as the pairs

Pricing runs on comparisons. When the pairs are right, the whole chain works with them: alerts, reports, repricing, all pulling in the same direction.
02 The gaps are invisible

Barcode-only tools leave coverage gaps

When a seller doesn't publish your identifiers, code-dependent tools can't see the product. Matching on names, images, and attributes keeps those products in view.
03 250ml with 250ml

Variants need attribute-level care

Same name, different size, pack count, or bundle. Attribute-level checks keep 250ml with 250ml and bundles with bundles, so comparisons stay honest.
04 Weeks, then forever

DIY matching is a project that never ends

Matching a catalog by hand takes weeks. Then new products launch and new sellers appear, and the spreadsheet starts again. Altosight turns the treadmill into an upload.

Evaluation Criteria

Key features to look for in product matching software

Everyone claims accuracy. These six things decide whether the claim survives your catalog.

AI on names, images, and attributes

The match is built from what's actually on the page: how the product is named, what it looks like, its size, color, and model. Not just a code that may or may not exist.

You hold the final say

Every match is confidence-scored and yours to control: accept, replace, or remove in seconds. Edge cases are flagged for human eyes before they matter.

Barcodes welcome, never required

EAN, UPC, ASIN, SKU: used to strengthen the match whenever they're present. When they're missing, names, images, and attributes carry it. Full coverage either way.

Variant and bundle awareness

Size, pack count, color, and bundle composition are part of the match. Your 250ml never gets compared to a 500ml, and specific variants can be tracked in their own right when you need them.

Cross-language, cross-market

The same product in different languages, naming conventions, and country catalogs resolves to one entry in yours. Multi-country data stays one coherent dataset.

Matches you control

Every match is visible with its confidence score, and editable in seconds: accept, replace, remove, or add listings you want tracked. No black box.

Questions

Frequently asked questions

No, and we're glad to use them. Identifiers strengthen a match whenever they're present.

When they're missing or inconsistent, the AI matches the way a careful person would: product names, images, and attributes like size, color, and model. Coverage stays complete either way.

99.9%+ on verified matches. Every candidate pair is scored for confidence: strong pairs go live, uncertain ones are flagged, with human verification on the edge cases.

And the final say is always yours. Accept, replace, or remove any match, anytime.

Size, pack count, color, and bundle composition are part of the match, not noise around it. Your 250ml is never compared to a rival's 500ml, and a 2-pack is never priced against a single unit.

When you need specific variants tracked in their own right, that's supported too.

Yes. The same product listed in different languages, naming conventions, and country catalogs is matched to one entry in yours.

That's how multi-country monitoring stays one coherent dataset instead of one dataset per market.

Yes, completely. Every match is visible with its confidence score, and you can accept, replace, or remove any of them in seconds, or add listings you want tracked.

Most clients skim the flagged pairs once during setup and rarely think about matching again.

It's included in every Altosight plan, from $49/month, along with monitoring, alerts, repricing, and free API access. Matching isn't an add-on. It's the foundation everything else stands on.
