Dynamics 365 certs split by functional consultant role: MB-800 for Business Central (ERP), MB-310 for Finance, MB-330 for Supply Chain, MB-230 for Customer Service, and MB-500 for Finance & Operations apps. These are niche but well-paid — fewer people hold them, which makes them stand out on a resume.
