WA Procurement Data - Who Gets Washington's Money

Washington state's government procurement data - the official data.wa.gov open datasets - packaged as clean, queryable, low-cost data layers.

This is the WA Procurement ecosystem: every actor answers the question who is getting Washington's money - through master contracts, and through long-tail procurement (Amazon Business).

👋 Pick the right tool

Your goal	Start here
Who won master contracts - vendor, amounts, diversity tiers, quarterly + annual sales, aggregate by contractor/customer	WA Master Contracts (wa-master-contracts) - live
Who buys what through Amazon - agency-level long-tail orders, by category / UNSPSC / date / amount, anomaly monitoring	WA Agency Amazon Spend (wa-amazon-spend) - live

Both datasets are free public WA state open data; you pay for the packaged, queryable layer - not the data itself.

Predictable, low-cost pricing

• From $0.001 per record - a tenth of a cent per record, on free public open data.
• Charge cap - every run is capped, so even a full-corpus query can't surprise-bill.
• Free public source - no data cost, you pay for packaging + analysis.

WA Master Contracts (wa-master-contracts)

Pull Washington state's master contract sales - 245,831 records / $25.4B of quarterly sales, 2015-present.

Built for AI agents, developers, and market-intelligence users who need to know who is getting Washington's money, at what amounts, across which agencies, and through which diversity-tier vendors.

What this data is

Each record is one sales line: a vendor (contractorName) sold to a customer (customerName, e.g. a state agency or university) under a master contract (contractNumber / contractTitle) in a given year, with quarterly and annual sales amounts, plus diversity flags:

Field	Meaning
contractorName	The vendor that won the contract
customerName / customerType	Buying agency / university
contractNumber / contractTitle	The master contract
year	Sales year (2015-2026)
quarterlySales / annualSales	USD amount (Q1-Q4 + annual total)
diversityFlags	smallBusiness, vetOwned, womanOwned, minorityOwned, diverseOptions

Diversity flags are first-class. Washington's data carries OMWBE categories (W=woman-owned, M=minority-owned, MW=both) plus veteran-owned and small-business flags - so you can filter or aggregate by diversity tier directly, no external join needed.

Typical questions it answers

• Who won Washington's money? Aggregate by contractor -> total sales, year coverage, diversity.
• What does a specific vendor take? e.g. contractorName=MICROSOFT -> every sales line.
• Which agencies buy from small businesses? Filter diversity=smallBusiness, group by customer.
• How does a vendor's take trend across years? Rows carry year; compare year-over-year.
• Which master contracts are biggest? Aggregate by contract, sort by totalSales.

Diversity compliance report (diversityReport)

The "Access Equity" compliance angle: aggregate by customer (agency) or contractor and see how much of each group's spend went to diversity-tier vendors:

Output field	Meaning
totalSales / diversitySales	Group's total vs diversity spend
pctDiversity / pctSmallBusiness / pctWomanOwned / pctMinorityOwned / pctVetOwned	Share percentages
diversityVendors	Distinct diversity vendors used

Example: ENTERPRISE SERVICES DEPT (WA's procurement agency) spends only ~2% of its $762M on diversity vendors - the kind of compliance signal agencies need to self-audit.

Inputs (all optional)

Input	What it does
keywords	Match any keyword against contractor / customer / contract title
contractorName	Substring match on vendor name
customerName	Substring match on agency / university
customerType	e.g. State Agency, Higher Ed (State Agency)
contractNumber	Exact master contract number
year	Exact sales year (e.g. 2025)
minAnnualSales	Only records at or above a dollar amount
diversity	Only records with a flag set: smallBusiness / womanOwned / minorityOwned / vetOwned
aggregate + groupBy	Roll up by contractor / customer / contract -> total sales, years, diversity present
diversityReport + reportGroupBy	Diversity compliance report (see above)
maxResults	Cap the number of records (default 200)

Data source & freshness

• Source: data.wa.gov - WA State Master Contracts (Socrata SODA API, free public, no login).
• Update cadence: quarterly - this is intelligence / analysis data (who got paid), not a real-time bid feed.
• Coverage: statewide master contracts only (customer-side); agency-level procurement (WEBS) is behind a login.
