Every ASIN's stock against its lead time. From Amazon's own vendor report.
Vendor Inventory reads your Vendor Central inventory report every day and sorts every ASIN by risk: SROoS, runs out before a PO can land, excess, then aged or unsellable. A second tab scores supply: confirmation rate, receive fill rate and lead time by day, week, month, quarter or year. It answers to you alone.
Included on the Enterprise plan — part of the OptimalCentral suite, one subscription.
Stock, cover and supply for every ASIN.
Amazon's fields from your vendor report. Ours: weeks of cover, the aged 90+ share, lead time in weeks, and the prior-period averages.
Inventory health
Sellable units and cost, aged 90+ share, unsellable and excess units, and ASINs with SROoS above 0, then every ASIN sorted by risk.
Weeks of cover
Sellable units divided by average weekly ordered units over the newest 6 complete sales weeks ending on or before the selected period. It sits next to Amazon's lead time for that ASIN, or the account average when the ASIN has none.
Supply scorecard
Confirmation rate, receive fill rate, lead time, open PO and net received units. The newest period next to the average of the six before it.
Alerts on changes only
An ASIN that crosses into a risk state goes into your alert email. An ASIN that stays in that state stays on the page and is not emailed again.

Frequently asked questions.
What does Vendor Inventory show?
Two views of your Vendor Central inventory report, per ASIN. Inventory health: sellable units and cost, weeks of cover, lead time, SROoS (sourceable retail out-of-stock rate: Amazon's Sourceable product OOS% for the selected period), aged 90+ day and unsellable units, excess units and sell-through, sorted by risk. Supply scorecard: confirmation rate, receive fill rate, lead time, open PO units and net received units by day, week, month, quarter or year.
Where does the data come from?
From your own Vendor Central inventory report, pulled once a day through your connected vendor account. Every field is Amazon's. Four figures are ours, computed from those fields: weeks of cover, the aged 90+ share, lead time in weeks, and the average of the six prior periods. Weeks of cover is sellable units divided by average weekly ordered units over the newest 6 complete sales weeks ending on or before the selected period.
How current is it?
Each morning we pull every day Amazon has published by then, and the page says which day is the newest. Amazon's documentation says a day's vendor data is available 72 hours after the day ends.
Does it send alerts?
Yes. When an ASIN crosses into SROoS above 0 (sourceable retail out-of-stock rate, newest day), runs out before a PO can land, excess, or aged or unsellable, it goes into your alert email. Excess is checked on the newest week: Amazon leaves it blank for single days. An ASIN that stays in that state stays on the page and is not emailed again. Your first day is silent.
Can it change my POs or shipments?
No. Vendor Inventory only reads. It does not confirm, change or create purchase orders or shipments. The agent audits, you act.
Which plans include Vendor Inventory?
Enterprise, with a connected Vendor Central account. It is not in the 14-day free trial, which covers the Brand plan's tools.
