Frequently Asked Questions
What makes a good enterprise Microsoft consulting firm?
A top enterprise Microsoft consulting firm should have: Microsoft Solutions Partner designation with multiple specializations, deep expertise across the full Microsoft stack (Azure, M365, Power BI, SharePoint, Dynamics, Copilot), compliance experience for regulated industries (HIPAA, SOC 2, FedRAMP), proven enterprise deployments (Fortune 500 references), fixed-fee engagement options, and post-implementation managed services. EPC Group meets all of these criteria with 28+ years of Microsoft-exclusive focus.
How much does enterprise Microsoft consulting cost?
Enterprise Microsoft consulting ranges from $175-$500/hour depending on the firm and specialization. Fixed-fee engagements for specific services: Power BI Quick-Start ($25,000), M365 Security Hardening ($25,000), Azure Landing Zone ($40,000), SharePoint Migration ($50,000+), Copilot Readiness ($15,000). Full enterprise transformations range from $200,000-$1,000,000+. EPC Group offers transparent fixed-fee pricing across all service lines.
Should I choose a Microsoft-focused firm or a multi-vendor consultancy?
For organizations with 80%+ Microsoft stack, a Microsoft-focused firm like EPC Group delivers deeper expertise and faster implementation. Multi-vendor consultancies (Accenture, Deloitte, Capgemini) spread expertise across AWS, GCP, Salesforce, and other platforms — meaning your engagement team may have less specialized Microsoft knowledge. Microsoft-focused firms also maintain closer Microsoft engineering relationships, access to preview features, and deeper certification coverage.
What is the Microsoft Solutions Partner designation?
Microsoft Solutions Partner replaced the Gold/Silver Partner designations in 2022. It requires firms to demonstrate customer success, skilling (certified consultants), and performance across six solution areas: Data & AI, Digital & App Innovation, Infrastructure, Modern Work, Security, and Business Applications. Partners can also earn Advanced Specializations for specific capabilities. EPC Group holds Solutions Partner designations with multiple Advanced Specializations.
How do I evaluate Microsoft consulting firm references?
Ask for: 1) References in your specific industry (healthcare, finance, government), 2) Similar-scale deployments (user count, server count), 3) Compliance-specific references if you operate in regulated industries, 4) Post-go-live support and managed services references, 5) References from the last 12 months (not 5 years ago). Request permission to contact references directly without the firm present. Verify the firm actually delivered the work versus subcontracting.
What Microsoft services do enterprise consulting firms cover?
Comprehensive enterprise Microsoft consulting covers: Azure (IaaS, PaaS, data, AI, security), Microsoft 365 (Exchange, SharePoint, Teams, OneDrive, compliance), Power Platform (Power BI, Power Apps, Power Automate), Dynamics 365 (ERP, CRM, Field Service), Security (Defender, Sentinel, Entra ID, Purview), Copilot (M365 Copilot, Azure AI, Copilot Studio), and specialized areas (migrations, governance, managed services). EPC Group covers all of these from a single Microsoft-focused practice.
