Municipal ERP powered by Dynamics 365 Business Central integrates finance, utilities, permitting, and payroll into a unified system of record for government operations. Internal staff and external citizens authenticate via Microsoft Entra ID with SSO, RBAC, and MFA before accessing core ERP, Power Platform digital services, and municipal extensions. Data flows from Dynamics 365 through API and file-based connectors to external systems including SAMAView, ArcGIS, Sensus AutoRead, and payment processors, with all activity monitored and reported through Financial and Operational Reporting dashboards. This architecture demonstrates how to modernize municipal operations while maintaining security boundaries and audit compliance across citizen-facing and internal workflows.
