SharePoint Consulting Services: Enterprise-Grade Expertise

By Errin O'Connor, Chief AI Architect at EPC Group | Updated April 2026

SharePoint remains the document management and collaboration platform of choice for Fortune 500 companies, government agencies, and large enterprises. EPC Group has delivered over 5,200 SharePoint deployments across 29 years — from on-premises farm builds to modern SharePoint Online intranets, complex migrations, and Copilot-ready governance frameworks.

Why Enterprises Need Specialized SharePoint Consulting Services

SharePoint is deceptively simple at small scale and punishingly complex at enterprise scale. A 50-person company can self-deploy SharePoint Online in a day. A 50,000-person enterprise with 15 years of on-premises content, complex permission models, compliance obligations, and integrations across ERP, CRM, and line-of-business applications requires specialized SharePoint consulting services to avoid costly mistakes.

The most common failure pattern we see is organizations attempting enterprise SharePoint initiatives with generalist IT staff or consultancies that treat SharePoint as "just another SaaS app." The result is ungoverned sprawl, broken permissions, poor adoption, and a platform that becomes a liability rather than an asset.

EPC Group's SharePoint consulting services are designed for organizations where SharePoint is mission-critical infrastructure — not an afterthought.

Our SharePoint Consulting Service Offerings

SharePoint Migration Services

Migration is our highest-volume SharePoint engagement type. We migrate organizations from SharePoint 2013/2016/2019 to SharePoint Online, from file shares and network drives to SharePoint document libraries, from competing platforms (Box, Dropbox Business, Google Workspace) to SharePoint, and between Microsoft 365 tenants during mergers and acquisitions. Every migration preserves metadata, version history, permissions, and workflow logic — the four elements that generalist migration firms routinely lose.

Governance Framework Design

Governance is the difference between a productive SharePoint environment and chaotic digital sprawl. EPC Group designs governance frameworks that balance user autonomy with organizational control: site provisioning request workflows, content type hierarchies, retention label policies, permission models based on least privilege, and lifecycle management that automatically archives abandoned content. We implement these policies through automation, not policy documents that users ignore.

Intranet and Portal Development

Modern SharePoint intranets powered by communication sites, Viva Connections, and SPFx web parts deliver consumer-grade employee experiences. EPC Group designs and builds enterprise intranets that serve as the digital front door: company news, HR resources, IT self-service, department hubs, executive dashboards, and integrated search across SharePoint, Teams, and Yammer. Our intranets achieve 80%+ daily active usage rates because we prioritize user research and information architecture over visual design.

Custom SPFx Development

When out-of-the-box SharePoint functionality falls short, our developers build custom SharePoint Framework (SPFx) solutions: web parts, extensions, Adaptive Card Extensions (ACEs) for Viva Connections, and full-page applications. We follow Microsoft's best practices for SPFx development, including proper tenant-wide deployment, CDN optimization, and accessibility compliance.

Power Platform Integration

SharePoint combined with Power BI, Power Automate, and Power Apps transforms document repositories into intelligent business process platforms. EPC Group builds integrated solutions: approval workflows that route SharePoint documents through Power Automate, Power Apps front-ends for SharePoint list data entry, and Power BI dashboards embedded directly in SharePoint pages for real-time business intelligence.

Managed Services

For organizations that need ongoing SharePoint expertise without hiring full-time specialists, EPC Group offers managed services: monthly admin hours, proactive monitoring, quarterly health checks, patch management for hybrid environments, governance enforcement, and a dedicated account architect who knows your environment intimately. Managed services engagements typically start at 20 hours/month and scale with organizational needs.

Enterprise SharePoint Challenges We Solve

  • Post-migration chaos: Your last consultant migrated the data but left you with broken permissions, missing metadata, and no governance. We remediate and rebuild.
  • Sprawl and shadow IT: Thousands of sites, no naming conventions, no lifecycle management. We implement governance automation that brings order without disrupting productivity.
  • Compliance failures: Audit findings related to PHI, PII, or financial data in SharePoint. We implement sensitivity labels, DLP, and retention policies aligned with Microsoft 365 compliance frameworks.
  • Low adoption: Users bypass SharePoint for email attachments and personal OneDrive. We redesign information architecture, build compelling intranets, and run adoption programs that drive behavioral change.
  • M&A integration: Two organizations on separate Microsoft 365 tenants need to consolidate. We plan and execute tenant-to-tenant migrations with minimal user disruption.
  • Copilot readiness: Copilot deployment requires clean permissions and well-structured content. We prepare your SharePoint environment for AI-powered collaboration.

Industries We Specialize In

While EPC Group serves all industries, we maintain deep SharePoint specialization in sectors where compliance and scale create unique challenges:

  • Healthcare: HIPAA-compliant SharePoint environments for clinical document management, research collaboration, and patient records workflows.
  • Financial Services: SOC 2 and SOX-compliant SharePoint deployments for trading floor collaboration, regulatory filing management, and audit documentation.
  • Government: FedRAMP and NIST 800-53-compliant SharePoint implementations in GCC and GCC High environments for federal, state, and local agencies.
  • Education: FERPA-compliant SharePoint deployments for student records, faculty collaboration, research data management, and administrative workflows.
  • Manufacturing: SharePoint-based quality management systems, engineering document control, and supply chain collaboration portals.

Frequently Asked Questions

What SharePoint consulting services does EPC Group provide?

EPC Group provides end-to-end SharePoint consulting services including migration (on-premises to SharePoint Online, tenant-to-tenant, third-party platforms to SharePoint), governance framework design, intranet and portal development, custom SPFx solutions, Power Platform integration, security and compliance hardening, managed services, and Copilot readiness assessments. We serve organizations from 500 to 200,000+ users.

How long does a typical SharePoint migration take?

Timeline depends on scope: a straightforward 1TB on-premises to SharePoint Online migration for 500 users typically takes 8-12 weeks. Large-scale migrations (50TB+, 10,000+ users, complex permissions) run 16-32 weeks. Tenant-to-tenant migrations during M&A are typically 12-20 weeks. EPC Group uses ShareGate, Microsoft Migration Manager, and custom PowerShell automation to optimize throughput while preserving metadata and permissions.

Do you support both SharePoint Online and SharePoint Server on-premises?

Yes. While most new engagements focus on SharePoint Online, EPC Group maintains deep on-premises expertise for SharePoint Server 2019 and SharePoint Server Subscription Edition. We support hybrid configurations, farm health assessments, upgrade planning, and eventual cloud migration. Many of our government and healthcare clients operate hybrid environments due to data residency requirements.

What makes EPC Group different from other SharePoint consulting firms?

Three differentiators: First, 29 years of exclusive Microsoft focus — we do not split attention across Salesforce, Google Workspace, or AWS. Second, our founder Errin O'Connor is a Microsoft Press bestselling author with four published books on SharePoint, Power BI, and Azure. Third, we maintain a bench of senior architects (15+ years average experience) who handle enterprise complexity that generalist firms cannot.

Can EPC Group help with SharePoint governance after migration?

Governance is where most migrations fail post-deployment. EPC Group designs governance frameworks covering site provisioning policies, naming conventions, content type standards, retention policies, permission models, and lifecycle management. We implement governance automation using Power Automate, third-party tools like ShareGate Apricot, and custom PowerShell to enforce policies without relying on user compliance.

SharePoint Architecture: 2026 Considerations for Blog SharePoint Consulting Services Enterprise

SharePoint Premium (formerly Syntex) document processing brings AI-powered metadata extraction, unstructured document classification, and prebuilt Document Understanding models to enterprise content management. Pricing in 2026 runs $5/user/month for the M365 Copilot-bundled tier; at typical Fortune 500 scale that is $360K-$600K annually, justified primarily through reduced manual data-entry labor and tighter retention compliance.

Modern SharePoint information architecture in 2026 follows the hub-spoke pattern: 1 root hub per business unit, 5-15 spoke sites per hub, mega-menu navigation tied to Viva Connections, and sensitivity-label-driven sharing controls. Flat-IA legacy SharePoint farms migrating to this pattern typically see 60% faster content discovery, 40% reduction in 'where do I save this?' helpdesk tickets, and 100% sensitivity-label coverage within 90 days.

Decision factors EPC Group evaluates

  • Audit (Premium) configuration for 6-year retention
  • Sensitivity label rollout with auto-classification rules
  • Microsoft Purview content explorer for unauthorized PHI/PII discovery
  • Hub-spoke information architecture redesign vs legacy flat-IA
  • Migration tool selection (Microsoft native vs ShareGate vs AvePoint) by complexity tier
