Inventory Health
Know what you have, what's running low, and what's costing you storage fees before it becomes a problem.
01
Days of supply check
How many days will my current FBA stock last at my current sales rate? Show me every SKU with less than 14 days of supply, sorted by days remaining. Include current fulfillable quantity and average daily units sold.
SELLER CENTRAL Run weekly. Anything under 14 days needs a reorder decision now.
02
Stockout risk forecast
Which of my products are at risk of stocking out in the next 21 days? My average lead time from PO to FBA check-in is 30 days. Show the SKU, current stock, daily sell rate, estimated days until stockout, and whether I need to reorder today to avoid a gap.
SELLER CENTRAL Adjust the lead time to match your actual supplier timeline.
03
Overstocked items
Which SKUs have more than 90 days of supply based on my current sell-through rate? Show the SKU, fulfillable quantity, days of supply, and estimated monthly storage cost. Sort by days of supply descending.
SELLER CENTRAL Overstocked items eat into margin via long-term storage fees. Consider promotions or removal orders.
04
Inbound shipment tracker
What inventory do I have currently in transit to FBA? Show me each inbound shipment with SKU, quantity, and shipment status. For any SKUs with less than 14 days of supply, flag whether there's inbound stock that will cover the gap.
SELLER CENTRAL Pairs well with the stockout risk prompt to see if help is already on the way.
05
Vendor on-hand snapshot
How many sellable units does Amazon have on hand for each of my ASINs? Show weeks of cover for each, and flag any ASIN with less than 4 weeks of cover. Also show any open purchase order quantities.
VENDOR CENTRAL Vendor inventory is managed by Amazon, but you still need to monitor it for PO planning.
Fee Analysis
Amazon fees can silently eat your margin. Know exactly what you're paying and where the money goes.
06
Fee breakdown by SKU
What are my estimated FBA fees per SKU? Show the referral fee, FBA fulfillment fee, and total estimated fee for each. Sort by total fee descending and flag any SKU where total fees exceed 40% of the selling price.
SELLER CENTRAL SKUs where fees exceed 40% of price are at risk of being unprofitable.
07
Estimated vs. actual fees
Compare my estimated FBA fees to what I was actually charged in my last settlement. For each SKU, show the estimated fee, actual settled fee, and the difference. Are there any SKUs where actual fees are significantly higher than estimated?
SELLER CENTRAL Catches fee discrepancies that add up over thousands of units.
08
Profitability audit
What percentage of my revenue goes to Amazon fees for each of my top 20 products by sales? Show revenue, total fees, refund amount, and net after fees. Flag any product where fees + refunds exceed 50% of revenue.
SELLER CENTRAL The real question isn't "what sold the most?" but "what made the most money after Amazon takes their cut?"
09
Refund & reimbursement check
How much have I lost to customer refunds in the last 30 days? Break it down by ASIN. Also show any Amazon reimbursements I've received. Which ASINs have the highest refund rate as a percentage of units sold?
SELLER CENTRAL High refund rates signal product quality or listing accuracy issues.
10
Vendor margin analysis
What is my net pure product margin (Net PPM) by ASIN? Show revenue, COGS, shipping costs, and net margin for each. Which ASINs have the lowest margin, and is my overall Net PPM trending up or down over the last 90 days?
VENDOR CENTRAL Net PPM is the single most important profitability metric for vendors.
Sales & Traffic
Understand what's selling, what's converting, and where your traffic is coming from.
11
Top sellers & trends
What are my top 15 products by revenue over the last 30 days? For each, show units sold, revenue, sessions, page views, and conversion rate. Compare to the prior 30 days and flag anything that changed more than 20%.
SELLER CENTRAL Your Monday morning dashboard. Spot winners and problems in one prompt.
12
Conversion rate deep dive
Which of my ASINs have the lowest conversion rates over the last 30 days? Show session count, page views, units ordered, and conversion rate. Only include ASINs with at least 100 sessions so we filter out low-traffic noise.
SELLER CENTRAL Low conversion with decent traffic = listing problem, not a visibility problem.
13
Buy box health
Which of my ASINs have a buy box percentage below 90% over the last 14 days? Show the ASIN, buy box %, sessions, and revenue. For any below 80%, is the trend getting worse week over week?
SELLER CENTRAL Lost buy box = lost sales even with good traffic. Investigate competitor pricing or listing issues.
14
Vendor sales gap analysis
What are my ordered units vs. shipped units by ASIN for the last 30 days? Flag any ASIN where there's a gap of more than 10% between ordered and shipped. Also show ordered revenue trending over the last 90 days — which ASINs are growing and which are declining?
VENDOR CENTRAL An ordered-vs-shipped gap means Amazon is ordering more than you can fulfill, or canceling POs.
15
Vendor traffic & glance views
Which of my ASINs are getting the most detail page views (glance views) over the last 30 days? Show the top 15 by glance views with buy box percentage. Flag any ASIN where glance views dropped more than 20% compared to the prior 30 days.
VENDOR CENTRAL Sudden traffic drops can signal suppressed listings, lost buy box, or competitor activity.
Reorder Planning
Turn your inventory and sales data into actionable purchase orders. Never stockout or overstock again.
16
Reorder point calculator
Calculate reorder points for all my active SKUs. My lead time is 35 days from PO to FBA check-in and I want 14 days of safety stock. Show me each SKU with its average daily sales rate, reorder point quantity, current stock, and whether I should reorder now.
SELLER CENTRAL Adjust lead time and safety stock days to match your supply chain.
17
Purchase order draft
Based on my current stock levels and the last 60 days of sales velocity, generate a suggested purchase order. For each SKU that needs reordering, show current stock, daily sell rate, days until stockout, and suggested order quantity to cover the next 60 days plus 14 days safety stock.
SELLER CENTRAL Pro tip: Export this and send it to your supplier as a starting PO.
18
Vendor forecast vs. inventory
Compare Amazon's demand forecast for my products to my current sellable on-hand inventory. Flag any ASIN where the forecasted demand for the next 4 weeks exceeds my current stock. Show the forecast quantity, on-hand quantity, and the gap.
VENDOR CENTRAL When Amazon's forecast outpaces your inventory, expect POs you can't fill — or worse, stockouts.
Search & Discovery
Understand how customers find your products and where they drop off in the purchase funnel.
19
Top search terms
What search terms are driving the most clicks and purchases for my products? Show the top 25 search terms by purchase share, with click share, conversion rate, and which of my ASINs appear for each term.
SELLER CENTRAL Requires Brand Analytics. These are the keywords your organic listing strategy should protect.
20
Search funnel leaks
For my top 20 search terms by impressions, show me the full funnel: impressions, clicks, cart adds, and purchases. Where am I losing the most customers? Flag any term where I get clicks but the cart-add or purchase rate is significantly below average.
SELLER CENTRAL High clicks but low cart adds = pricing or listing issue. High cart adds but low purchases = checkout friction or competitor undercutting.
21
Market basket opportunities
What products are frequently bought together with mine? Show the top cross-purchase combinations with my ASINs, the percentage of orders that include each combo, and whether the paired product is one of mine or a competitor's.
SELLER CENTRAL Cross-sell opportunities: bundle with your own products, or target competitor's complementary items in ads.
22
Repeat purchase loyalty
Which of my products have the highest repeat purchase rate? Show the ASIN, repeat purchase percentage, and total orders. For my top 5 repeat-purchase products, are any at risk of stocking out?
SC + INVENTORY Stocking out on high-repeat products is the most expensive stockout — you lose the customer for good.
Cross-Data Intelligence
The real power: combine inventory, sales, fees, and ads data to make decisions no single report can support.
23
Stock-aware ad scaling
Which of my advertised products have less than 14 days of FBA stock remaining? Show the ASIN, current stock, days of supply, daily ad spend, and ACOS. For any with low stock, should I reduce ad spend to preserve inventory until my next shipment arrives?
ADS + SC Scaling ads on a product with 5 days of stock left just accelerates the stockout and tanks your ranking.
24
Organic winners worth advertising
Show me products with strong organic sales (top 25% by revenue) that don't have any active Sponsored Products campaigns. Include the ASIN, organic revenue, units, conversion rate, and current FBA stock level. Which of these have enough stock to support an ad campaign?
ADS + SC Products already selling well organically are your best ad candidates — product-market fit is already confirmed.
25
Organic vs. paid keyword gaps
Compare my Brand Analytics search terms to my active ad keyword targets. Which search terms drive organic clicks to my products that I'm not bidding on? And which keywords am I bidding on that don't appear in my organic search terms? Show both gaps.
ADS + SC Organic traction you're not bidding on = easy wins. Paid keywords with no organic presence = dependency risk.
26
High traffic, low conversion audit
Which products have high ad spend but below-average organic conversion rates? Show the ASIN, ad spend, ad clicks, organic sessions, organic conversion rate, and the account average conversion rate. These are products where fixing the listing will improve both paid and organic performance.
ADS + SC If your conversion rate is below average, the problem is the listing, not the ads. Fix the listing first.
27
True profitability by product
For my top 20 products by total revenue, calculate the true profitability: total revenue minus Amazon fees minus ad spend minus refund costs. Show each product with revenue, fees, ad spend, refunds, and net profit. Rank by net profit, not revenue.
ADS + SC Your #1 product by revenue might be #10 by profit. This prompt reveals the truth.
28
Fee burden on top sellers
For my best-selling products, what percentage of revenue goes to Amazon fees vs. ad spend? Show revenue, FBA fees, referral fees, ad spend, and the combined take rate for each. Are my highest-revenue products also my most efficient, or are fees eating the margin?
ADS + SC When fees + ads exceed 50% of revenue, you're working for Amazon, not yourself.
29
Slow movers to cut
Which SKUs have the worst combination of low sell-through rate, high storage fees, and poor ad performance (ACOS above 50% or zero ad sales)? Show sell-through rate, estimated monthly storage cost, ad spend, ad sales, and ACOS. These are candidates for liquidation or discontinuation.
ADS + SC Sometimes the best optimization is killing products that are bleeding money across all dimensions.
30
Vendor replenishment + ad coordination
For my vendor products, which ASINs have low weeks of cover but high glance views and active ad campaigns? Show the ASIN, weeks of cover, glance views, ad spend, and ad sales. Flag any where I should pause ads to slow demand until Amazon replenishes, or where I should push Amazon for a larger PO.
ADS + VENDOR Vendors can't control stock directly, but you can control ad spend to match Amazon's replenishment pace.
