10,000+ implementations. 29 years. NPS 100. See how a senior-led Microsoft specialist outperforms Accenture, Deloitte, and Big 4 firms across every dimension that matters.
Every enterprise IT leader faces the same question: do we hire a Big 4 consulting firm with brand recognition, or a specialized firm with deeper expertise and better economics? If you are evaluating Microsoft consulting partners for Power BI, SharePoint, Azure, AI governance, or Microsoft 365, this page gives you the honest, data-backed comparison.
EPC Group is not trying to be Accenture. We are not a 500,000-person generalist firm that sells everything from SAP to Salesforce to strategy decks. We are a senior-led Microsoft specialist that has delivered 10,000+ implementations across Fortune 500 organizations, federal agencies, and healthcare systems over 29 years. Our model is fundamentally different — and for Microsoft-focused initiatives, it delivers better outcomes at lower cost.
What follows is a transparent, 10-dimension comparison. We do not claim to be better at everything — we claim to be better at Microsoft-specific enterprise implementations, and we back that claim with metrics.
The #1 objection we hear from procurement teams is: "Can a boutique firm handle our scale?" The answer is not just yes — it is that our model handles scale better than the Big 4 approach.
Consider how Big 4 firms actually deliver projects. A senior partner (20+ years experience) sells the engagement and appears at the kickoff meeting. Then they disappear. The actual work is performed by analysts and consultants with 1-3 years of experience, supervised by a manager with 5-7 years. You are paying senior rates ($350-500/hour) for junior-level delivery. The Big 4 firms need 15-20 people on a project because most of them are still learning.
EPC Group inverts this model. Every engagement is staffed with senior architects who have 15+ years of Microsoft expertise. There are no junior consultants. No offshore delivery centers. No staff rotation. One EPC Group architect replaces 3-5 junior Big 4 consultants because they have already solved the same problem dozens of times. This is the special forces model — smaller teams, deeper expertise, faster outcomes.
This is not a theoretical comparison. These numbers reflect real proposals we have won against Big 4 competitors. The client gets deeper expertise, faster delivery, and a fixed price — at roughly 40-60% of the Big 4 cost. The "boutique scale concern" evaporates when you realize that four senior architects produce more output than fifteen mixed-experience consultants.
An honest side-by-side evaluation across the dimensions that determine consulting engagement success. Scores are based on client feedback, industry benchmarks, and 29 years of competitive experience.
Senior architects (15+ years) on every engagement from day one through delivery
Senior partner sells the deal, then staffs junior consultants (1-3 years experience)
Fixed-fee and outcome-based pricing. You know the total cost before signing.
Time & materials billing. Scope creep drives costs 40-200% over initial estimates.
First deliverable in 2-4 weeks. No 3-month "discovery phase" padding.
8-16 week discovery and planning phases before any tangible output.
29 years of pure Microsoft ecosystem expertise. 4 Microsoft Press books published.
Multi-vendor generalists. Microsoft is one of 20+ technology practices.
HIPAA, FedRAMP, SOC 2, GDPR, ITAR — built into every engagement by default.
Compliance expertise available but requires separate (expensive) workstreams.
EPC Analytics Operating Model (EAOM) — repeatable 5-pillar framework proven across 10,000+ implementations.
Proprietary frameworks that prioritize billable hours over rapid outcomes.
Same team from scoping through support. Zero consultant rotation mid-project.
Average 30-40% staff turnover per year. Your team changes every 3-6 months.
Scope and price locked at SOW signing. Change orders only for client-requested scope additions.
Rarely offer fixed-fee. T&M billing with "estimate ranges" that always hit the ceiling.
Zero governance failures across 10,000+ implementations. AI governance built-in.
Governance as an add-on service. Higher failure rates due to junior-staffed implementations.
NPS score of 100 — every client would recommend EPC Group.
Average NPS of 30-50 across major consulting firms (industry benchmarks).

We believe in honest positioning. There are scenarios where a Big 4 firm is the better fit:
For everything else in the Microsoft ecosystem — Power BI, SharePoint, Azure, Microsoft 365, AI governance, Microsoft Fabric, Copilot — EPC Group delivers superior outcomes. If you want senior architects who solve problems instead of junior consultants who document them, talk to us.
Unlike Big 4 firms where compliance expertise sits in a separate practice (and separate budget), EPC Group builds compliance into every engagement by default. Our architects understand HIPAA at the technical control level, not just the policy level. They configure SharePoint permissions, Azure security, and Power BI row-level security with compliance requirements baked in — not bolted on as an afterthought.
HIPAA, HITECH, 21st Century Cures Act
PHI protection in Power BI dashboards, SharePoint document management, and AI-assisted clinical workflows.
SOC 2, FINRA, SEC, GLBA
Audit-ready data governance, encrypted data pipelines, and role-based access across analytics platforms.
FedRAMP, ITAR, FISMA, CMMC
GCC High and DoD IL4/IL5 implementations, zero-trust architecture, and classified environment support.
FERPA, COPPA, State Privacy Laws
Student data protection, parent portal governance, and analytics with PII masking.
Fortune 500 companies choose EPC Group when they need deep Microsoft expertise delivered by senior architects — not junior consultants learning on the job. Our clients consistently cite three reasons: (1) the same senior team that scopes the project delivers it, (2) fixed-fee pricing eliminates the cost overruns endemic to Big 4 T&M billing, and (3) our 29 years of pure Microsoft focus means faster time to value. We have delivered 10,000+ implementations with an NPS of 100 — a score no Big 4 firm achieves.
Yes. EPC Group operates as a "special forces" model — a smaller, senior-heavy team that delivers the same (or better) outcomes as large consulting firms. We have completed migrations for 10,000+ user environments, deployed Power BI across Fortune 500 organizations, and implemented AI governance frameworks for federal agencies. The difference is we do it with 15-year veterans, not 200 junior consultants billing at senior rates.
EPC Group typically costs 40-60% less than equivalent Big 4 engagements. We achieve this through fixed-fee pricing (no scope creep), senior-only staffing (fewer hours needed because experienced architects work faster), and zero overhead from massive office footprints and management hierarchies. A Power BI Center of Excellence that a Big 4 firm quotes at $500K, EPC Group delivers for $200-300K with better outcomes and faster timelines.
The special forces model means every EPC Group engagement is staffed with senior architects who have 15+ years of Microsoft expertise — there are no junior consultants, no offshore teams, and no staff rotation. Like military special forces, our teams are smaller, more experienced, and faster than conventional units. One EPC Group architect replaces 3-5 junior Big 4 consultants because they have already solved the problem dozens of times before. This model delivers better quality at lower cost with shorter timelines.
EPC Group holds Microsoft Gold Partner-level expertise across Power BI, SharePoint, Azure, Microsoft 365, and AI/ML. Our founder Errin O'Connor is a Microsoft Press bestselling author of four books — a credential no Big 4 partner can match. We maintain direct escalation paths to Microsoft engineering teams for complex technical issues. Our certifications are not just badges; they represent 29 years of hands-on enterprise implementation experience.
Big 4 consulting firms experience 30-40% annual consultant turnover, which means your project team changes every 3-6 months. You spend weeks re-explaining context to new people. At EPC Group, the architect who scopes your project is the same person who delivers and supports it. We have zero mid-project consultant rotation. This continuity means no knowledge loss, no re-ramp time, and a team that knows your environment as well as your own IT staff.
EPC Group specializes in compliance-heavy industries where governance failures carry severe consequences: healthcare (HIPAA), financial services (SOC 2, FINRA), government and defense (FedRAMP, ITAR), education (FERPA), and legal. Our compliance frameworks are built into every engagement by default — not sold as an expensive add-on. This specialization means we understand your regulatory constraints before the first meeting.
EPC Group uses fixed-fee pricing with clear scope definitions in every SOW. If you request additional scope, we provide a transparent change order with a fixed price before proceeding — there are no surprise bills. If we underestimate effort due to our own scoping, we absorb the cost. This is fundamentally different from Big 4 T&M billing where every conversation, email, and meeting adds to your invoice.
