Overview

The Seller Inventory Run Rate dashboard is the operational view of inventory health for Amazon Seller Central businesses. It answers the practical question every seller needs to ask multiple times per week: which ASINs are about to stock out, which are overstocked, and how soon do I need to ship more units?

Each ASIN in your catalogue is assigned to a Stock Category (Out of Stock, Critical Stock, Low Stock, Sufficient Stock, Overstock, or ASIN not in AMZ report) based on its current inventory level and recent sales speed. The dashboard separates FBA (Fulfilled by Amazon) and FBM (Fulfilled by Merchant) inventory side by side, then provides an ASIN-level detail table with replenishment signals, traffic, and Buy Box context to support shipment planning.

This dashboard covers Seller Central data only. Vendor Central inventory is tracked separately.

What You Can See on This Dashboard

The dashboard is structured in two blocks: a top-level stock health overview (FBA vs FBM), followed by an ASIN-level detail table for replenishment planning.

Section 1 — FBA Current Stock: Stock Health Breakdown

A pie chart showing how many of your FBA ASINs sit in each Stock Category right now. This is the fastest way to see whether your FBA-fulfilled portfolio is healthy or whether a wave of stockouts is forming.

Stock Category definitions:

• Out of Stock — Inventory Level is 0. The ASIN is unavailable to buy and is actively losing sales.

• Critical Stock — Run Rate is less than 3 days, with active sales velocity. Urgent replenishment needed.

• Low Stock — Run Rate is between 3 and 7 days. Replenishment should be initiated soon.

• Sufficient Stock — Run Rate is greater than 7 days, or stock is present but no sales were recorded in the last 7 days. No immediate action required.

• Overstock — Run Rate is greater than 84 days. Consider pausing replenishment or running promotions.

• ASIN not in AMZ report — No inventory data from Amazon in the last 30 days. The ASIN may be inactive, suppressed, or not yet fulfilled.

How Run Rate is calculated: Sellable On Hand Units ÷ average daily Ordered Units over the last 7 days. The result is the estimated number of days until current stock runs out.

Visualization: Pie chart with one slice per Stock Category, sized by the number of FBA ASINs in that category.

Section 2 — FBM Current Stock: Stock Health Breakdown

The same view as Section 1, but for FBM (Fulfilled by Merchant) ASINs — products you ship yourself rather than through Amazon's warehouses. Categories and calculation logic are identical to FBA.

Visualization: Pie chart with one slice per Stock Category, sized by the number of FBM ASINs in that category.

Note: If you fulfil exclusively through one channel, the other pie chart will show "No data". This is expected.

Section 3 — Run Rate Summary per ASIN (FBA and FBM)

The operational core of the dashboard: a full ASIN-level table covering both FBA and FBM inventory, with all the columns needed to plan replenishment for the next shipment cycle.

Columns shown:

• Stock Category — The bucket the ASIN currently falls into (see definitions above).

• Fulfillment Channel — FBA or FBM.

• Picture · Product Title · ASIN · SKU · Marketplace — Product identifiers.

• Tracked — Whether the ASIN is actively tracked in your account.

• Run Out Date — Estimated calendar date on which stock will reach zero at the current sales pace.

• Run Rate [Days] — Estimated days until stock runs out (Sellable On Hand Units ÷ Sales Speed 7 Days, rounded down).

• Sales Speed 3 Days / 7 Days / 30 Days — Average units ordered per day over the last 3, 7, or 30 days. Comparing the three reveals whether velocity is accelerating or decelerating.

• Time to Action — Run Rate minus a 5-day assumed seller lead time. A negative value means the ASIN would already be out of stock by the time a shipment arrived if you started today.

• Inventory Level — Current Sellable On Hand Units.

• Demand Forecast [6W] — Forecasted units needed over the next 6 weeks: Sales Speed (7 days) × 42.

• Units to Send — The shipment size suggested to cover the 6-week forecast: Demand Forecast [6W] minus current inventory.

• Avg. Page Views [30 Days] + trend vs. the preceding 30-day period — A leading indicator of whether traffic (and therefore future demand) is growing or declining.

• Buy Box Percentage + 30-day trend — Your latest share of Buy Box impressions, and how it has moved over the last month. A drop here typically suppresses sales velocity and changes your replenishment math.

• Last Seen — The most recent date Amazon reported data for this ASIN. Useful for sanity-checking ASINs in the "ASIN not in AMZ report" bucket.

Visualization: Sortable, scrollable table — one row per ASIN per fulfilment channel.

Available Filters

Filter interaction notes

• Subcategory depends on Category. Selecting a Category narrows the Subcategory dropdown to only the relevant values.

• Stock Category is the most useful filter for daily operations — set it to Critical Stock + Out of Stock to focus the ASIN table only on items that need immediate action.

• Fulfillment Channel affects both pie charts and the detail table. If you set it to FBA only, the FBM pie will show "No data".

• All filters apply across all three sections simultaneously.

Use Cases

1 — Daily stockout firefighting

You want to know, first thing in the morning, which ASINs need an urgent reshipment.

• Set Stock Category = Critical Stock + Out of Stock.

• Open the Run Rate Summary per ASIN table and sort by Time to Action (most negative first).

• For each ASIN, read Units to Send to know the suggested shipment quantity.

• Cross-check Buy Box Percentage — if you have lost the Buy Box, a stockout has less immediate revenue impact, but you should still fix the underlying issue.

2 — Weekly replenishment planning

You plan your shipment to Amazon's fulfilment centres once a week.

• Filter Fulfillment Channel = FBA.

• Set Stock Category = Critical, Low, Sufficient (exclude Overstock and Out of Stock for replenishment planning).

• Use the Units to Send column to size the upcoming shipment per ASIN.

• Sanity-check Sales Speed 7 Days vs Sales Speed 30 Days — if the 7-day figure is much higher than the 30-day, demand is accelerating and you may want to ship more than the forecast suggests; if much lower, demand is cooling and you should send less.

3 — Identifying overstock to clear

You want to free up FBA storage capacity (and reduce long-term storage fees).

• Set Stock Category = Overstock, Fulfillment Channel = FBA.

• Sort the table by Run Rate [Days] descending to find the ASINs with the deepest stock cover.

• Consider promotions, price reductions, or removal orders for the worst offenders.

4 — Investigating "missing" ASINs

Some ASINs are not showing up in your sales reports and you want to know why.

• Set Stock Category = ASIN not in AMZ report.

• Check the Last Seen column to see when Amazon last reported data for each ASIN.

• These ASINs are typically inactive, suppressed (e.g. detail page issues, compliance flags), or not yet fully set up in Seller Central — investigate each case directly in Seller Central.

5 — Sales velocity trend check before a peak season

You want to know which ASINs are accelerating ahead of a peak event (e.g. Prime Day, Q4).

• Open the Run Rate Summary per ASIN table without category filters.

• Compare Sales Speed 3 Days vs Sales Speed 7 Days vs Sales Speed 30 Days — ASINs where 3-day > 7-day > 30-day are accelerating.

• Cross-reference with Avg. Page Views [30 Days] Trend to confirm whether the acceleration is being driven by rising traffic.

• Increase Units to Send beyond the standard 6-week forecast for these ASINs.

Limitations & Notes

• Seller Central only. This dashboard reflects Seller Central inventory. Vendor Central sell-in and warehouse stock are not included here.

• Run Rate uses the 7-day sales speed. The Stock Category assignment is sensitive to short-term demand swings. An ASIN with a spike day in the last week can flip from Sufficient Stock to Low Stock overnight, and vice versa. For longer-term planning, compare the 7-day and 30-day sales speeds in the detail table.

• Lead time assumption. Time to Action assumes a 5-day seller lead time between deciding to ship and Amazon receiving the units. If your real lead time is longer (e.g. international freight), apply your own buffer when reading this column.

• Demand Forecast is a simple extrapolation. Demand Forecast [6W] = Sales Speed (7 days) × 42. It does not include seasonality, promotional uplift, or marketing plans — treat it as a baseline and adjust manually for known events.

• ASIN not in AMZ report. This bucket means Amazon has not reported inventory data for the ASIN in the last 30 days. It is not the same as "out of stock" — the ASIN may simply be inactive, suppressed, or newly added. Check Last Seen and the Seller Central listing directly.

• FBM data depends on your inventory feed. FBM stock levels reflect what you have reported to Amazon. If your FBM inventory feed is delayed or stale, the Run Rate will be too.

• Buy Box Percentage is a snapshot. It reflects Amazon's most recent reported value with a 30-day comparison; short-lived Buy Box wins or losses between snapshots may not be captured.

• Stock Category vs Fulfillment Channel filters interact. If you filter by an FBA-only Stock Category mix and set Fulfillment Channel to FBM, the table will return no rows — this is expected.
