ARA (Amazon Retail Analytics)

Amazon & D2C glossary · Harpy Media

ARA (Amazon Retail Analytics) is the 1P vendor’s reporting suite inside Vendor Central: sales, inventory, traffic (glance views), and marketing performance by ASIN — the wholesale-side counterpart of a 3P seller’s business reports.

What is ARA?

Where 3P sellers watch sessions and conversion, vendors watch glance views and sell-through against Amazon’s purchases. Same underlying market, different lens — and vendors who read ARA fluently walk into Amazon negotiations with the one thing vendor managers respect: their own numbers.

The reports that carry the load

Sales and traffic by ASIN: how much Amazon sold, how many shoppers looked — the vendor conversion read (orders over glance views). Inventory: what Amazon holds, weeks of cover, and the sell-in versus sell-out gap that predicts the next PO. Geographic and repeat-purchase slices where available. The discipline: watch sell-OUT (what shoppers bought), not just sell-IN (what Amazon ordered) — the difference is the demand signal that justifies (or refutes) your next cost-price conversation.

Using ARA in vendor negotiations

ARA data is your evidence base at the AVN and every QBR: which ASINs drive Amazon’s margin, which carry inventory risk, where sell-through outpaces Amazon’s ordering (your case for bigger POs), and where promotion actually moved units (your case against generic co-op increases). Vendor managers arrive with their dashboards; the vendor who arrives with theirs — read better — negotiates as a peer instead of a counterparty.

In practice

A vendor notices via ARA that a mid-tier SKU’s sell-out runs 30% above Amazon’s reorder cadence — shoppers buying faster than Amazon restocks, with intermittent stockouts visible in the data. They present the gap at the QBR with a proposal: higher PO frequency on that ASIN in exchange for holding co-op flat. The data makes the case; Amazon agrees; sell-in rises to match the demand it was missing.

⚠️ Watch out. A vendor reads only the top-line sales chart each month and misses the divergence underneath: glance views up 40% while orders stay flat. Amazon’s retail team eventually reads the conversion drop their way — pricing, placement, or delisting conversations start without the vendor ever having seen them coming. The data was in ARA the entire time.

💡 Harpy tip. Track sell-in versus sell-out per ASIN monthly. The gap between them is your next negotiation, your next stockout, or your next CRAP-listing warning — depending on who reads it first.

How Harpy Media helps

Vendor-side, we run ARA as the negotiation evidence file — because the side with better data doesn’t just argue better, it sets the agenda.
