Inventory Intelligence — Data-Driven Stocking & Aging Analysis

Turn sold market data and live supply counts into actionable stocking recommendations. Replace gut-instinct buying with demand-to-supply ratios, aging alerts, turn-rate benchmarks, and optimal new-vs-used mix targets.

Dealer Profile (Load First)

→ Full procedure: read _references/profile-loading.md

Parse marketcheck-profile.md → extract: dealer_id, dealer_type, franchise_brands, zip/postcode, state/region, country, dom_aging_threshold. If missing: tell user to run /onboarding.

Country routing: US = all tools. UK = search_uk_active_cars only. get_sold_summary NOT available — skip Market Demand Snapshot, D/S Ratio, Turn Rate, New vs Used Mix. Only Aging Inventory Alert works for UK. → Full matrix: _references/country-routing.md

→ Agent contracts (lot-scanner, lot-pricer): read _references/agent-contracts.md

Confirm: "Using profile: [dealer.name], [State/Region], [Country]"

User Context

The following fields are loaded from the dealer profile. Only ask if no profile exists:

• Role: Dealer (single rooftop or group) or OEM regional manager — ask if unclear
• Location: Auto-loaded from profile (state for US, region for UK)
• Dealer ID: Auto-loaded from profile (used for lot-level queries)
• Franchise brand(s): Auto-loaded from profile
• Timeframe: Default to the most recent full month; ask if they want a custom date range
• Inventory type focus: New, Used, or Both (default Both) — ask if unclear
• Dealer type: Auto-loaded from profile

Do not guess dealer IDs or locations. If the profile has dealer_id: null, ask before running lot-level workflows (Aging Inventory Alert, Category Gap).

Gotchas

• seller_type=dealer is hardcoded in supply queries — this intentionally excludes private sellers and auction listings to give an accurate dealer-competitive supply count.
• UK: only Aging Inventory Alert works — Market Demand Snapshot, D/S Ratio, Turn Rate, and New vs Used Mix all require get_sold_summary which is US-only. Inform UK dealers immediately.
• Facet syntax: make|0|50|2 means "facet on make, offset 0, up to 50 buckets, minimum 2 documents per bucket." The min_count of 2 filters out singleton listings.
• dealer_id: null blocks lot-level workflows — Aging Inventory Alert and Category Gap require a dealer_id. If the profile has dealer_id: null, ask before running these workflows.
• Custom date ranges need validation — default to the most recent full month. If the user requests a custom range, ensure dates use first-of-month to last-of-month format (e.g., 2026-01-01 to 2026-01-31).
• D/S Ratio thresholds differ from stocking-guide — here, ratio > 1.5 = Under-supplied, 0.8-1.5 = Balanced, < 0.8 = Over-supplied (stocking-guide uses higher thresholds for bid decisions).

Workflow: Market Demand Snapshot

Understand what is actually selling in the user's market before making any stocking decisions.

1. Call mcp__marketcheck__get_sold_summary with:

   • date_from: first day of the target month (e.g. 2026-01-01)
   • date_to: last day of the target month (e.g. 2026-01-31)
   • state: user's 2-letter state code
   • dealer_type: user's dealer type (Franchise or Independent)
   • ranking_dimensions: make,model
   • ranking_measure: sold_count
   • ranking_order: desc
   • top_n: 20

2. Call mcp__marketcheck__get_sold_summary with the same date and location filters, but:

   • ranking_dimensions: body_type
   • ranking_measure: sold_count
   • ranking_order: desc
   • top_n: 10

3. Present results as two ranked tables:

   • Top 20 Models by Sales Volume — columns: Rank, Make, Model, Sold Count, Avg Sale Price, Avg DOM
   • Sales by Body Type — columns: Body Type, Sold Count, Share of Total (%)

4. Highlight any body type or model where the user's franchise brand appears in the top 5, and flag segments where it does not appear (potential conquest or gap opportunities).

Workflow: What Should I Stock? (Demand-to-Supply Ratio)

Compare what the market is buying against what dealers currently have listed. Vehicles with high demand and low supply represent stocking opportunities.

1. Call mcp__marketcheck__get_sold_summary with:

   • date_from / date_to: most recent full month
   • state: user's state
   • dealer_type: user's dealer type
   • ranking_dimensions: make,model
   • ranking_measure: sold_count
   • ranking_order: desc
   • top_n: 30

2. Call mcp__marketcheck__search_active_cars with:

   • state: user's state (or zip + radius if provided)
   • car_type: used (or new based on user focus)
   • seller_type: dealer
   • dealer_type: user's dealer type
   • facets: make|0|50|2,model|0|50|2
   • rows: 0 (we only need facet counts, not individual listings)

3. For each of the top 30 sold make/model combinations, look up the active supply count from the facet results.

4. Calculate Demand-to-Supply Ratio = Sold Count (monthly) / Active Supply Count.

   • Ratio > 1.5 = Under-supplied (strong stocking opportunity)
   • Ratio 0.8 - 1.5 = Balanced
   • Ratio < 0.8 = Over-supplied (avoid stocking more)

5. Present a single table sorted by demand-to-supply ratio descending:

   • Columns: Make, Model, Monthly Sold, Active Supply, D/S Ratio, Signal (Under-supplied / Balanced / Over-supplied)
   • Bold or call out the top 5 under-supplied models as priority acquisition targets.

Workflow: Aging Inventory Alert

Identify units on the dealer's lot that have exceeded healthy DOM thresholds and assess their current market value.

Multi-agent approach: Use the lot-scanner and lot-pricer agents for complete, paginated results.

Step 1 — Pull aged inventory (paginated):

Use the Agent tool to spawn the marketcheck-cowork-plugin:lot-scanner agent with this prompt:

Pull aging inventory for dealer_id=[dealer_id], country=[country], car_type=used, sort_by=dom, sort_order=desc, dom_range=[dom_aging_threshold]-999. Paginate through all results.

This ensures ALL aged units are captured, not just the first 25.

Step 2 — Price aged units (US only):

After lot-scanner returns, use the Agent tool to spawn the marketcheck-cowork-plugin:lot-pricer agent with this prompt:

Price these aging vehicles: [pass vehicle list from lot-scanner]. zip=[zip], dealer_type=[dealer_type], floor_plan_per_day=[floor_plan_per_day], aging_threshold=[dom_aging_threshold].

UK dealers: Price inline using comp medians from search_uk_active_cars.

Validate (after Step 2)

• lot-scanner returned pagination_status=complete — if partial, warn user in output
• lot-pricer returned pricing for all passed VINs — if some failed, note count in output
• No predicted_price = $0 or null in pricing output
• Every VIN in pricing output matches a VIN from lot-scanner aging results

Step 3 — Build the report from lot-pricer output:

3. Build an Aging Inventory Report table:

   • Columns: VIN (last 6), Year, Make, Model, Trim, DOM (days), Listed Price, Predicted Market Price, Price Gap ($), Price Gap (%), Recommendation
   • Recommendation logic:
     • Price Gap > +10% (overpriced): "Reduce price to market — estimated $X reduction"
     • Price Gap -5% to +10%: "At market — consider wholesale if DOM > 90"
     • Price Gap < -5% (underpriced): "Below market — review for quick retail sale"

4. Summarize total aged inventory exposure:

   • Count of units > 60 DOM, > 90 DOM, > 120 DOM
   • Estimated total floor plan interest burn (units x avg $30/day x avg DOM over 60)
   • Total overpricing gap across all aged units

Workflow: Turn Rate by Segment

Benchmark how quickly different vehicle segments move in the local market to inform category-level stocking.

1. Call mcp__marketcheck__get_sold_summary with:

   • date_from / date_to: most recent full month
   • state: user's state
   • dealer_type: user's dealer type
   • ranking_dimensions: body_type
   • ranking_measure: average_days_on_market
   • ranking_order: asc
   • top_n: 10

2. Call mcp__marketcheck__get_sold_summary with:

   • Same date/location/dealer_type filters
   • ranking_dimensions: make,model
   • ranking_measure: average_days_on_market
   • ranking_order: asc
   • top_n: 10

3. Also call with ranking_order: desc and top_n: 10 to get the slowest turning models.

4. Present three tables:

   • Turn Rate by Body Type — columns: Body Type, Avg DOM, Sold Count, Interpretation
   • Fastest Turning Models (Top 10) — columns: Make, Model, Avg DOM, Sold Count
   • Slowest Turning Models (Bottom 10) — columns: Make, Model, Avg DOM, Sold Count

5. Provide a recommendation: "Focus acquisition on segments with Avg DOM < X days (market median). Avoid over-stocking in segments where Avg DOM exceeds Y days unless priced aggressively."

Workflow: New vs Used Mix Analysis

Determine the optimal new-to-used inventory ratio based on what the market is actually absorbing.

1. Call mcp__marketcheck__get_sold_summary with:

   • date_from / date_to: most recent full month
   • state: user's state
   • inventory_type: New
   • ranking_dimensions: make
   • ranking_measure: sold_count
   • ranking_order: desc
   • top_n: 10

2. Call mcp__marketcheck__get_sold_summary with same filters but:

   • inventory_type: Used

3. Call mcp__marketcheck__search_active_cars for current supply:

   • state: user's state
   • car_type: new
   • seller_type: dealer
   • facets: make|0|30|2
   • rows: 0

4. Repeat with car_type: used.

5. Calculate:

   • Market Absorption Ratio: New Sold / (New Sold + Used Sold) for the market
   • Current Supply Ratio: New Active / (New Active + Used Active) on lots
   • Gap: If supply ratio significantly exceeds absorption ratio, the market is over-indexed on new (or used)

6. Present as:

   • Summary box: "Market absorbed X% New / Y% Used last month. Dealers currently stock A% New / B% Used. Recommendation: [shift toward new/used/hold steady]."
   • Breakdown table by make with columns: Make, New Sold, Used Sold, New % of Sales, Current New Supply, Current Used Supply, Supply vs Demand Alignment

KPIs & Business Impact

→ After assembling results, read references/outcomes.md to frame recommendations with quantified business impact, KPI benchmarks, and action-to-outcome guidance.

Output Format

• Lead with the headline number. Example: "Your market sold 1,247 used SUVs last month. You have 3 units in stock. Demand-to-supply ratio: 415:1."
• Use tables for ranked data (top models, body types, aging units). Keep tables to 10-20 rows max; offer to show more if needed.
• Color-code signals in text: use "UNDER-SUPPLIED", "BALANCED", "OVER-SUPPLIED" labels clearly.
• Always include dollar impact when discussing aging or stocking recommendations. Dealers think in dollars, not abstractions.
• End with 3 specific action items the user can execute today (e.g., "1. Reduce price on VIN ...X4532 by $2,100 to match market. 2. Target 2024 Toyota RAV4 at auction below $28,500. 3. Wholesale the 3 sedans over 120 DOM to free up $87,000 in floor plan.").
• Cite the data period in every output (e.g., "Based on January 2026 sold data for Texas franchise dealers").

Self-Check (before presenting to user)

• Tables have consistent column counts
• No $0 or null prices displayed
• D/S ratios calculated as sold/supply (NOT supply/sold)
• "UNDER-SUPPLIED" / "BALANCED" / "OVER-SUPPLIED" labels match the threshold definitions
• Data period cited in every output section
• Action items include specific dollar amounts and vehicle identifiers
• Aging alert floor plan burn uses profile's cost/day, not hardcoded $30
