If your organization wants to connect local entities to the headquarters ERP solution, you may have already discovered that your headquarters solution is too complex—and too costly—to adapt easily to specialized local requirements. Microsoft Dynamics ERP delivers flexible, affordable, and scalable two-tier ERP solutions that can connect your subsidiaries, divisions, branches, and lines of business to your headquarters solution.
With Microsoft Dynamics ERP as part of your two-tier solution, you can customize to meet specialized requirements, implement vertical functionality, and manage change easily and affordably to:
Optimize local operations while meeting enterprise-level requirements to consolidate financial and operational data.
Reduce complexity and simplify compliance by easily managing local tax, regulatory, and market requirements with multisite, multilanguage, and multicurrency capabilities.
Scale quickly and deliver industry-specific solutions where they are needed and add new functionality as business requirements change.
Lower total cost of ownership (TCO) through reduced training time and familiar, easy-to-use solutions and by maximizing your current IT investments with other Microsoft applications and technologies.
The Microsoft Dynamics ERP product lines, especially the highly scalable Microsoft Dynamics AX, have become the de facto ERP standard within certain subsidiaries and business units of large entities such as Boeing, Ingersoll Rand, and Sara Lee, even though the headquarters may be using a different system.
