Pennsylvania's eMarketplace publishes state-agency solicitations, with PennDOT being one of the largest infrastructure buyers east of the Mississippi. The state also runs a sizeable cooperative purchasing program (COSTARS) that small businesses can join.
Where Pennsylvania posts solicitations
The primary state portal is PA eMarketplace, based in Harrisburg. State agencies, public universities, and many quasi-public buyers publish there. Some larger agencies (departments of transportation, university systems) also maintain separate, agency-specific posting boards in addition to the central portal, so a working Pennsylvania search strategy usually pulls from multiple sources.

How Pennsylvania contracts differ from federal
State procurement is generally faster and less paperwork-heavy than federal procurement, but evaluation is less standardised — each agency runs its own process within the state’s overarching procurement code. Set-aside and preference programs vary: Pennsylvania typically operates its own state-level small business and diverse-supplier preference programs in addition to (and separate from) federal SBA programs. Vendors registered for federal SAM.gov work usually need a separate state vendor registration.
How WinAContract helps
We aggregate Pennsylvania state-portal postings alongside federal SAM.gov solicitations into one searchable index, with NAICS, agency, and deadline filtering and saved-search alerts. AI bid writing applies whether the solicitation is federal or Pennsylvania state-issued. See our federal contract search page for the federal side and AI RFP writing for the response workflow.
