The Honest Comparison
Accenture is a global management consulting and technology services firm with around 750,000 employees. EPC Group is a Microsoft-exclusive consulting firm, established in 1997. It has hundreds of senior consultants.
Both companies offer Microsoft consulting services, but they have different scopes and operating models:
- Accenture provides a wide range of services across various industries.
- EPC Group focuses exclusively on Microsoft technologies.
- Accenture has a larger global presence compared to EPC Group.
Important context: Accenture's Microsoft practice mainly operates through Avanade, a joint venture established in 2000. Clients often select between EPC Group and Avanade for Microsoft-specific projects. This page compares EPC Group with Accenture's wider practice, which includes both management consulting and technology delivery.

These offerings are not typically productized by a global SI focused on multi-cloud solutions.

All of this occurs without leaving the Microsoft governance perimeter, which includes Entra ID, Purview, and Defender.

Frequently Asked Questions
When should we choose Accenture over EPC Group?
Accenture is the right choice for multi-cloud Fortune 500 transformation programs (Microsoft + AWS + Google Cloud), management consulting + technology delivery combined, global business operations transformation where technology is one workstream of many, and engagements where Accenture's broader industry consulting practice (financial services advisory, supply chain consulting, sustainability) adds value beyond pure technology delivery.
When should we choose EPC Group over Accenture?
EPC Group is the right choice for Microsoft-only enterprises where deep Microsoft specialization matters more than multi-cloud breadth, US and Canada-scoped engagements without global multi-region requirements, regulated industries needing compliance-native Microsoft delivery (HIPAA, FINRA, FedRAMP, CMMC), mid-market to lower-Fortune-500 organizations where global SI pricing is not justifiable, M&A tenant consolidation common in private equity portfolios, and engagements where senior architects only + published methodology + named accountability are explicit procurement criteria.
What about Accenture's Microsoft practice specifically?
Accenture's Microsoft work largely flows through Avanade, the Accenture-Microsoft joint venture. For dedicated Microsoft consulting, the realistic comparison is EPC Group vs Avanade (see /epc-group-vs-avanade-microsoft-consulting-2026). Accenture's direct Microsoft practice exists but is smaller than Avanade's.
What is the scale difference?
Accenture has approximately 750,000 employees globally across all consulting practices. EPC Group has hundreds of senior Microsoft architects + delivery staff, US/CA only. The scale difference is structural, not coincidental — different operating models optimized for different scope.
What about pricing?
Accenture hourly billing for senior consultants typically runs at the top of the consulting market due to brand premium + global delivery overhead. EPC Group fixed-fee Consulting Blocks and Mid-Market Microsoft Fixed-Fee Catalog packages typically deliver 40-60% lower total cost for comparable Microsoft-specific scope at mid-market scale.
What about regulated industries?
Accenture has substantial regulated-industry consulting practice (financial services advisory, healthcare strategy, defense advisory) — primarily business and management consulting rather than dedicated Microsoft technical delivery. EPC Group has 29 years of dedicated Microsoft + regulated-industry technical practice with published industry-specific overlays (47-control HIPAA framework, 38-control FINRA framework, NIST SP 800-53 federal mapping, NIST SP 800-171 CMMC mapping).
Can we use both?
Yes. Some Fortune 500 enterprises use Accenture for management consulting + business transformation strategy + EPC Group for Microsoft-specific implementation + regulated-industry governance. The combination works when each firm's scope is defined upfront and governance frameworks are aligned.
What about multi-cloud strategy?
Accenture has strong multi-cloud capability (Microsoft + AWS + Google Cloud + Oracle). EPC Group specializes in Microsoft only, including Microsoft Foundry as a multi-model AI gateway running Claude + GPT + Gemini + Llama + Mistral inside Microsoft governance perimeter. For pure Microsoft strategies, EPC Group; for genuine multi-cloud strategies, Accenture.
What is EPC Group's Engagement Operating Model?
EPC Group's published seven-phase project management methodology (Discover, Architect, Plan, Build, Validate, Deploy, Run) with named artifacts at every phase, one accountable program manager throughout the engagement, and a senior Microsoft architect engaged from discovery through run state. See /engagement-model.
