Know if Amazon actually published your changes.
You optimise a title, bullets or a description in Seller/Vendor Central — and Amazon quietly ignores it, delays it for days, or rewrites it with its own AI. Epinium's Discrepancy Control compares your internal content field by field against the live public listing, so you catch exactly which products and which fields are out of sync.

What our clients say
Every SEO field, internal vs live
Discrepancy Control compares the content you keep in Seller/Vendor Central (what you want live) against what Amazon actually shows on the public product page (what buyers see) — and flags every gap.
From silent drift to a case you can file
Epinium pulls both sides — your internal content and the live public listing — compares them, and turns unapplied changes into an actionable case file for Amazon.
See every product where Amazon didn't apply your content
- Status tiles that filterSynced · Discrepancy · Pending publish · Unchecked counters at the top — click one to see only those products.
- Per-product rollupEach product shows a status per field and one overall state, so you spot problem listings at a glance.
- Marketplace-agnosticBuilt to audit any channel — Amazon today, more marketplaces later, without changing the workflow.
Exactly which words Amazon changed — or dropped
- Word-by-word diffA side-by-side internal ↔ public comparison highlights the differing words; if one side is empty it says "No content" instead of a false diff.
- See in storeJump straight to the live public product page on Amazon in one click to confirm what buyers actually see.
- Rule-aware statesA+ active → description shown as synced; vendor description → not-checkable. No false positives.

ExploreFrequently asked questions
Which fields does it compare?
Title, Item Highlights, bullet points and description. Search terms are not compared — Amazon no longer exposes public search terms. The description has special cases: with active A+ content it counts as synced, and on Vendor accounts Amazon doesn't expose the public description, so it shows as not-checkable.
When is a product "ready to open a case"?
When it is still in discrepancy and its Amazon listing hasn't updated for more than 72 hours. Before that: under 24h Amazon may still be propagating the change, and 24–72h is a grace period.
What does the Excel export include?
Only eligible products (in discrepancy, 72h+) and only the fields in discrepancy, respecting your active table filters. ASINs are grouped up to 5 per case with current vs requested text. It's generated in the background and delivered by email and in Downloads.
Why do some products show "Unchecked"?
A product only gets a status once it has been analysed. Never-audited products stay Unchecked until Epinium collects and compares their internal and public data.
