A Small Business Economic Impact Statement (SBEIS) is an analysis of the impact of a proposed rule impact on small businesses (Chapter 19.85 RCW).

A Cost-Benefit Analysis (CBA) looks at both the costs and benefits of the rule. When a rule is defined as a significant legislative rule and the agency is not exempt under RCW 34.05.328, the agency is required to complete a cost-benefit analysis for the rule file.
