The most useful public checklist is SHRM's 'The Ultimate Guide to Hiring a Benefits Broker' (HR Magazine, November 13, 2023). It is sponsored content written by SHRM's own broker-matching service: advice to employers, not a survey of what they do.
It recommends that every employer use an RFP or written questions, and says plainly that this does not mean or imply the employer should select a broker via RFP. Unless the employer requires a written bid, the guide calls the RFP only a supporting tool for the calls, meetings and finalist interviews that follow. It tells employers to review at least three and as many as six brokers, to start a selection as far ahead of the plan renewal date as possible, and names not having shopped in more than three years as one reason to run one.
Its broker overview asks for four things: ownership structure; the biographies and experience of the team that will serve the account; the fee and commission schedule, with agreement to transparency of payments from third-party carriers and vendors; and verification of licensing and adequate E&O coverage. The other core topics are the employer service model, employee services, health plan cost control, wellness, compliance, HR systems and support, and enrollment and employee services. Its cover letter explains why the employer is considering a new broker; if a request has that paragraph, read it first.
