What is DataDoe and how does it work for Amazon vendors?

DataDoe is the live data layer for Amazon Vendor Central. It connects every vendor account, sales/traffic/inventory analytics, Net Pure Product Margin (NPPM), demand forecasting, repeat-purchase performance and market-basket co-purchase analysis into one reconciled source of truth. Then it makes that data queryable through a built-in dashboard and through Model Context Protocol (MCP), so any modern AI tool — ChatGPT, Claude, Cursor, GitHub Copilot, Codex, Gemini CLI — can read your vendor data natively. One workspace, every brand, every marketplace.

What is Net Pure Product Margin and how does DataDoe track it?

Net Pure Product Margin (NPPM) is Amazon's vendor-specific profitability metric: shipped revenue minus shipped COGS minus customer returns, expressed as a percentage of shipped revenue. DataDoe pulls NPPM at the ASIN level daily, separately for both manufacturing-retail and sourcing-retail models, then reconciles trends by brand, marketplace and time period. Surfaces drift before it shows up in your monthly Vendor Central report — letting vendor ops teams catch margin erosion early instead of after the next PO is already cut.

How to connect Vendor Central to ChatGPT, Claude, or any AI tool?

Connect your Amazon Vendor Central account to DataDoe, then enable the MCP server integration. Any MCP-compatible AI tool can then query your vendor data natively.

What is MCP and why does it matter for Amazon vendors?

Model Context Protocol (MCP) is the open standard for connecting live data sources to AI tools and agents. For Amazon vendors, it means your Vendor Central data becomes natively readable by every modern AI agent without custom integration work. DataDoe runs as an MCP server — you connect your Amazon accounts once, and from that moment every MCP-compatible AI (ChatGPT, Claude, Cursor, etc.) can query your vendor data securely, continuously, and in plain English. Set up once, available everywhere.

What Amazon Vendor Central data does DataDoe pull in?

DataDoe pulls every vendor data feed Amazon publishes: daily sales, traffic and inventory metrics by ASIN (57+ fields including NPPM, glance views, sell-through rate, vendor confirmation rate, average vendor lead time, customer returns, on-hand inventory, aged 90+ days sellable inventory, unhealthy inventory). Plus weekly Customer Demand forecasts with mean expected demand and 70/80/90% confidence levels per ASIN, monthly repeat-purchase performance per ASIN, and monthly market-basket co-purchase analysis ranked by combination score. Initial historical load goes back up to 735 days.

How is DataDoe different from Amazon Brand Analytics in Vendor Central?

Vendor Central's Amazon Brand Analytics gives you the underlying data — sales, traffic, NPPM, forecasting, repeat purchase, market basket — for free, but only inside Amazon's UI, account by account, marketplace by marketplace, with manual CSV exports. DataDoe gives you the way to actually use it: continuous sync without re-pulling, multi-account / multi-brand / multi-marketplace reconciliation, prebuilt dashboards out of the box, and AI-readable through MCP so any AI tool can query it. Same Amazon data, surfaced where vendor ops teams actually work.

Can DataDoe handle hybrid 1P + 3P (Vendor Central + Seller Central) accounts?

Yes — hybrid 1P + 3P is one of DataDoe's strongest use cases. Vendor Central, Seller Central and Amazon Advertising accounts unify into a single workspace. NPPM and 1P vendor performance reconcile alongside 3P seller profit on the same ASINs, in the same queries. Vendors who run both channels finally see which channel actually makes more money per SKU — without manually cross-referencing between two Amazon portals or building custom Excel pivots.

How to export Vendor data to BigQuery, data warehouse, or my own backend?

DataDoe provides REST API and typed SDK access to export vendor data including amazon_vendor_sales_traffic_and_inventory_by_child_and_date, amazon_vendor_forecasting, amazon_repeat_purchase_report, and amazon_market_basket_by_child_asin tables to your own data warehouse or backend.

Is my Amazon Vendor Central data safe with DataDoe?

Yes. DataDoe is Amazon-audited and SP-API compliant, with secure OAuth-based authentication, per-tenant data isolation and encrypted storage. Your vendor data is never sold, never used to train AI models, and only readable by AI tools you explicitly connect through MCP. You can disconnect any AI integration or revoke any Amazon Vendor account access at any time from within DataDoe.

Vendor Central MCP & Data Layer for AI

Q: How do I track Amazon's demand forecast accuracy as a vendor?

DataDoe pulls Amazon's weekly Customer Demand forecast continuously — mean expected demand plus 70%, 80% and 90% confidence levels per ASIN — and compares it against your real sell-through history. Forecast gaps reveal supply chain mismatches before they become stockouts or overstocks. Ask the built-in dashboard or any connected AI ("where's Amazon's demand forecast off vs actual sell-through?") and get a list of at-risk ASINs in seconds, with the magnitude of the gap.

Where the upside is hiding

Six questions every vendor should be asking on day one.

These are the questions every Amazon vendor should be able to answer cleanly — and almost none can today. Each one is a single chat away once DataDoe is connected, or a click into the right report if you're using the built-in dashboards.

NPPM movement

1 – 3 pp

margin shifts you should catch early

"Which ASINs are dropping in NPPM right now?"

Net Pure Product Margin moves quietly — Amazon doesn't flag it. By the time you spot it in the monthly report, you've already shipped a quarter of the damage.

Aged inventory

5 – 15%

of stock potentially stranded at Amazon

"What's sitting unsold 90+ days at Amazon FCs?"

Aged sellable inventory ties up working capital and signals weak sell-through. Spot it early, sell it through with promo or accept the markdown — instead of letting it become unhealthy stock.

Forecast gaps

10 – 25%

supply mismatch potential

"Where's Amazon's forecast off vs reality?"

Amazon publishes weekly demand forecasts with 70/80/90% confidence levels. Compared to your real sell-through, the gaps reveal supply chain mismatches before they become stockouts.

Lead time creep

3 – 10 days

added to vendor lead times unnoticed

"Which ASINs have lead times getting worse?"

Vendor lead times trend silently. A few days extra per PO compounds into stockouts and lost margin — visible only when you track the trend, not the snapshot.

Repeat customers

Top 10%

ASINs driving most repeat revenue

"List ASINs that with most repeat purchase"

Repeat customer score by ASIN — rare data Amazon does share. Tells you which products are retention engines vs one-time buys, so you know where to double down on supply and bundles.

Cross-sell discovery

3 – 5x

basket lift potential per pairing

"What's purchased with my top ASINs?"

Market basket co-purchase data shows the actual ASINs customers buy alongside yours. Bundle opportunities, complementary listings, virtual bundles — all hidden in this monthly data feed.

What's actually in DataDoe for Vendors

Every vendor signal Amazon shares.
Reconciled by ASIN.

DataDoe pulls every Vendor data feed Amazon publishes — sales, traffic, inventory health, vendor confirmation rate, lead time, sell-through, Net Pure Product Margin, demand forecasting (70/80/90% confidence), repeat-purchase performance, market-basket co-purchase analysis. Both manufacturing-retail and sourcing-retail models tracked side by side.

Then it stitches everything together. NPPM reconciled across both retail models. Inventory health (sellable, unsellable, aged 90+ days, unhealthy) by ASIN by FC. Demand forecasts compared against real sell-through. Multi-brand, multi-marketplace — unified into one schema your AI can actually query.

And we expose it three ways: MCP (so any modern AI tool can read it natively), REST API (for your own backends), and a typed SDK (so AI coding tools can build apps against it without inventing field names). Plus the built-in DataDoe app sits on top of the same layer — you don't have to use any of those endpoints to get value on day one.

The math

From a stack of tools
to a single layer.

Most Amazon vendors run on a stack of tools — Amazon Brand Analytics, separate forecasting tools, inventory aging trackers, basket-analysis subscriptions, internal BI. Each with its own login, dashboard, roadmap and bill.

DataDoe replaces the data layer underneath all of them. The same questions, the same answers, the same custom views — built into the DataDoe app or built by your AI tool of choice on top of one unified workspace, on one subscription, with your data staying yours.
