How to Bid on Government Contracts in Delaware (2026 Guide)

Delaware buys through a central state purchasing office, and its cities, counties and school districts buy on their own as well. To sell to the state you register once as a vendor, then watch for solicitations in your commodity codes and respond by the deadline. This page covers the state registration steps, where bids are posted and the programs that help small businesses, with links to the official pages.

How to register as a Delaware vendor

Register for free in the Delaware Notification Service subscription portal (https://denotificationservices.bbcportal.com/) and select the business categories and commodity codes you want to track.
Add more than one company contact and allow email from @blackboard.com and State notification addresses so alerts are not filtered as spam.
Watch the Central Bids Directory (https://mmp.delaware.gov/Bids/) for RFIs, RFQs, ITBs and RFPs.
If a solicitation says to submit through Bonfire, create a free Bonfire account (email verification, company profile, commodity selection) before the deadline.
For under-threshold work, contact the agency, school district and municipal procurement contacts listed on MyMarketplace.

Registration gets you on the state's list, but it rarely sends you every relevant bid. Many agencies, and most local governments, post on their own portals. A free BidsNexus alert watches the state portal and Delaware's local agencies for you and emails the matches each morning.

Small business and certification programs

Office of Supplier Diversity (OSD) certification, Division of Small Business: Certifies minority, women, veteran, service-disabled veteran and disability-owned businesses, plus Small Business Focus (SBF) vendors, and lists them in the state directory of certified businesses.
DelDOT Disadvantaged Business Enterprise (DBE) Program: Listed on MyMarketplace vendor resources as the DBE program for transportation work.

Federal set-asides work differently from state programs; see our guide to small business set-asides.

Cities, counties and school districts

Counties and towns post their own bids on their own websites; MyMarketplace keeps a list of links for municipalities and political subdivisions (https://mymarketplace.delaware.gov/vendors/bids-poli-subs.shtml).

Local bids are where most small businesses win their first contracts: smaller dollar values, shorter responses and less competition from national firms. BidsNexus collects them into one list, so you can browse every open Delaware bid in one place.

Tips specific to Delaware

Formal bids are required for goods and non-professional services of $100,000 and over; $50,000 to $99,999.99 needs 3 written quotes and under $50,000 is open market.
For professional services under the formal threshold, agencies must seek at least one quote from a certified diverse vendor, so OSD certification can get you asked to quote.
Bonfire is only a submission tool; all opportunities are still advertised in the MyMarketplace Bid Directory, and late responses are not accepted.
Vendors are subject to minimum mandatory insurance requirements and may need a Delaware business license from the Division of Revenue.
