Why we are uniquely qualified to be your PEO Broker?

As health insurance premiums rise and administrative burdens make it difficult for smaller businesses to compete with larger corporations, the PEO market has been taking off. With over 700 PEOs in the U.S, it can be a daunting task to choose the right plan. This has created a market for PEO experts. While many brokers are looking to capitalize on this opportunity, a majority lack a fundamental understanding of the most complex aspect of the PEO, the Insurance Benefits. A&C Management professionals are not only PEO brokers, but are certified in Life, Accident, & Health. Therefore, we understand the true value of the insurance coverage PEOs provide and can better evaluate the cost-effectiveness of each plan. The medical insurance benefits are the number one cost cutter in using a PEO, and thus it is important that your PEO broker has expertise in this field. A&C Management’s foundation is derived in the insurance business, and has been working in the PEO market since its early years.
