Doing Business with ACS

The Administration for Children’s Services procures millions of dollars’ worth of goods and services to serve New York City’s children and families every year.

Goods and services are mainly obtained through:

  • Competitive Sealed Bids – contracts are awarded to the lowest responsible bidder that meets the requirements in an invitation for bids.
  • Request for Proposals (RFP) – vendors are selected through the evaluation of proposals.
  • Negotiated Acquisitions – vendors are selected through negotiations where an RFP or Bid is not practical or advantageous to the City.

ACS may also solicit vendor opinion on potential procurements through Concept Papers or Requests for Information.

New vendors must:

  1. Enroll in the City's Bidders' Lists through the Vendor’s Payee Information Portal (PIP).
  2. Submit an electronic prequalification application to the Health and Human Services (HHS) web-based accelerator system, HHS Accelerator(ONLY if seeking to provide social services to families).
