Updated: April 25, 2026 · By: Errin O'Connor, Founder & Chief AI Architect, EPC Group · Reading time: 17 min

Choosing a SharePoint consulting firm in 2026 is harder than 5 years ago because: (1) SharePoint and Microsoft 365 boundaries blur; (2) Copilot integration is now table stakes; (3) governance + AI grounding is an emerging requirement most firms can't deliver. Below is an honest comparison.

The 12 selection criteria

1. SharePoint implementation experience (>500 sites)
2. Microsoft Solutions Partner — Modern Work designation
3. Microsoft Copilot for Microsoft 365 governance experience
4. Compliance specialization (HIPAA, SOC 2, FedRAMP, CMMC)
5. Senior delivery model (≥40% senior architect hours)
6. Migration tooling expertise (ShareGate, Quest, native PnP)
7. Information architecture practice
8. SPFx + Power Platform development capability
9. Industry vertical experience
10. Pricing model transparency (fixed-fee vs T&M)
11. References (3+ Fortune 500 in past 12 months)
12. Post-implementation managed services capability

Frequently Asked Questions

Why include yourselves in this list?

Because we are one of the firms readers are evaluating, and listing competitors honestly helps readers make better decisions. Hiding our position would be obvious.

How does Avanade compare to EPC Group?

Avanade has more global scale and deeper pre-release Microsoft access. EPC Group has higher senior-architect-hour ratio, fixed-fee preference, and deeper compliance specialization. For Fortune 500 with US-centric delivery and compliance needs, EPC Group is often the better fit.

What about smaller boutique firms?

Many excellent boutiques exist (Withum's SharePoint practice, AdaptivEdge, RockCyber). Boutiques work well for Fortune 1000 and mid-market; for Fortune 500 with multi-region needs, larger firms (EPC Group, Avanade) typically scale better.

How do we evaluate references?

Ask: (1) Project size and timeline; (2) On-time / on-budget actuals; (3) Senior architect hours actually delivered; (4) Post-go-live support quality; (5) Would they hire the same firm again.

What about offshore delivery?

Offshore can save 30-50% on labor cost but architecture decisions made offshore (without US-based senior architect) often miss compliance + regulatory nuance. EPC Group's pattern: US-based seniors design + lead, with offshore augmentation only for execution roles.

Should we use Microsoft FastTrack?

FastTrack is free Microsoft technical guidance + limited deployment assistance. Pairs well with a partner-led implementation. Cannot replace partner labor for Fortune 500-scale work.

What is the right number of partners to RFP?

3-4. More than 5 introduces noise; fewer than 3 limits comparison.

Should we use multiple partners simultaneously?

Generally no. Single accountable partner with single SOW + single budget. If you must use multiple, split by clearly-bounded workstream (e.g., Partner A: SharePoint migration; Partner B: Copilot governance) with explicit handoff contracts.

How long is a typical SharePoint engagement?

Greenfield Fortune 500 SharePoint Online deployment: 16-32 weeks. Migration from on-prem: 32-52 weeks. Governance overlay only: 8-16 weeks.

What's the most overlooked partner skill?

Information architecture. Most firms can deploy SharePoint; few can design IA that scales for 10,000+ users.
