An MGA performs work delegated by an insurer, often including underwriting and binding within agreed limits. Some firms have both a brokerage business and MGA programs." - question: "Does a retail broker work with a wholesale broker or an MGA?" answer: "Either. A retail broker might approach an MGA directly for a program that suits the business, or use a wholesale broker to explore markets and work through a more complicated placement." - question: "Why do wholesale brokers and MGAs get treated as one industry segment?" answer: "They work in the same specialty insurance market, and some firms do both. Their trade associations, AAMGA and NAPSLO, merged in 2017 to form the Wholesale & Specialty Insurance Association (WSIA)." --- When a commercial account needs a market outside a retail agent's existing relationships, the next conversation might be with a wholesale broker or a managing general agent (MGA). Both can help move a placement forward, but they do different work with the submission. The terminology gets confusing because a single firm can have a wholesale brokerage business and its own MGA programs. The easiest way to understand the difference is to follow the file from the insured to the underwriting decision. ## Who does what? A retail broker works directly with the insured: understanding the business, gathering information and helping the client evaluate coverage. When the account needs another market, the retail broker can bring in a wholesale partner while keeping the client relationship. A wholesale broker helps the retail agent find markets and negotiate a placement. That can involve working out which underwriters are likely to consider the risk, presenting the account and resolving questions as terms come back. Those markets can include insurers and MGAs. An MGA performs work delegated by an insurer. That often includes assessing submissions, setting terms and binding coverage within the insurer's agreed guidelines. It may receive submissions directly from retail agents or through a wholesale broker. This explains why market access and binding authority are different ideas. A wholesale broker can get a difficult account in front of the right underwriter. An MGA may be able to make the underwriting decision itself. A firm with both operations can do different jobs on different placements. ## Why binding authority is only part of the definition The legal meaning of MGA is more specific than the everyday industry label. [California's definition](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=INS§ionNum=769.81.) addresses reinsurance, management and underwriting activities, premium volume and exceptions. The [NAIC's model act](https://content.naic.org/sites/default/files/model-law-225.pdf) also looks beyond binding authority and expressly notes that using the MGA title does not necessarily satisfy its definition. The NAIC document is model legislation; the applicable state law supplies the legal test. For a retail agent, the useful question is straightforward: can this underwriter decide on the submission, or does it need to go back to the insurer? That tells you more about the next step than the company's label alone. ## Why the two get talked about as one industry Wholesale brokers and MGAs work alongside each other in the specialty insurance market, and some firms operate both businesses. Their trade associations, the American Association of Managing General Agents (AAMGA) and the National Association of Professional Surplus Lines Offices (NAPSLO), [merged in 2017 to form the Wholesale & Specialty Insurance Association (WSIA)](https://www.wsia.org/wcm/News/WSIA_in_the_News_Archives.aspx). That shared industry home helps explain why the terms so often appear together. → [Get appointed with Nomos](https://nomos-insurance.com/get-appointed/) ## What this means for a submission An MGA program can be a useful starting point when the business fits a defined class and coverage offering. The underwriter may be able to handle the file within that program's guidelines, with fewer referrals back to the insurer. A wholesale broker can help when the placement needs a broader search or more work to explain the risk. The broker develops the presentation and works with insurers or delegated underwriters to find a workable option. In either route, missing information and underwriting referrals can affect how long a quote takes. Our [wholesale comparison library](/compare/) looks at these differences across brokerage, MGA and digital placement models.
