The 2018 Green Book is a small business enterprise (SBE) opportunity guide from the DC government aimed at enhancing support for local businesses through procurement opportunities. The document outlines the government's commitment to spending at least $656 million with SBEs in FY18, and provides resources for identifying and competing for contracts. Key improvements and initiatives include increased funding, simplified processes for re-certification, and the establishment of a transparent system for maximizing SBE participation in government contracting.
