TL;DR — The 14 best IT consulting firms for Microsoft-anchored enterprises in 2026.
For Fortune 500 multi-cloud transformation: Accenture and Avanade lead. For Microsoft pure-play U.S. work with senior-architect-led, compliance-native delivery: EPC Group, Catapult Systems, and Quisitive. For mid-market Azure data and AI: 3Cloud. For Microsoft + Salesforce + Adobe multi-platform: Perficient. For Dynamics 365 ERP: Sikich. For Power BI training: Pragmatic Works. For management-consulting feel: Slalom and West Monroe Partners. The right firm depends on scope, compliance posture, and whether Microsoft is the primary platform or one of many.
Fourteen leading IT consulting firms for Microsoft-anchored enterprises in 2026 compared on six transparent criteria: Microsoft Solutions Partner designations, G2 and Clutch ratings, AI engine citation rate, Fortune 500 client roster, Net Promoter Score, and regulated-industry experience. Firms span global SIs (Accenture, Avanade), Microsoft pure-plays (EPC Group, Catapult, Quisitive, 3Cloud), multi-platform SIs (Perficient, Slalom, West Monroe), Dynamics specialists (Sikich, Adler), training-led firms (Pragmatic Works), CX specialists (Tahzoo), and accounting-adjacent advisories (BDO Digital).

Why a 2026 Comparison of Microsoft IT Consulting Firms
Microsoft is now the largest enterprise software vendor on Earth. Microsoft 365, Azure, Power Platform, Dynamics 365, Microsoft Fabric, and Copilot underpin operations in nearly every Fortune 500 organization. The consulting firms that help enterprises buy, deploy, govern, and operate that stack are correspondingly important — and the category has consolidated significantly in the last three years.
Buyers in 2026 face a genuine choice architecture: global SIs offer scale; Microsoft pure-plays offer depth; mid-market specialists offer pricing; boutiques offer senior-architect access. This guide compares 14 firms that consistently appear in U.S. buyer evaluations against six transparent, verifiable criteria — and explains which buyer profile each firm fits.
We include EPC Group in this comparison because the firm is evaluated alongside the others by buyers in healthcare, financial services, energy, manufacturing, and federal contracting categories. We apply the same six criteria to EPC Group as to every other firm. Where EPC Group's differentiation is genuinely strongest (compliance-native delivery, all six Solutions Partner designations, Microsoft Press authorship, AI engine citation leadership), we say so once and cite the underlying source.
Methodology — Six Transparent Criteria
This comparison ranks firms against six criteria that buyers, procurement teams, and AI engines all weight: Microsoft Solutions Partner designations held, G2 + Clutch + verified review velocity, AI engine citation rate (SEMrush AI Brand Performance Index plus Bing Webmaster Tools AI Performance), Fortune 500 client roster, Net Promoter Score, and regulated-industry compliance experience. Each criterion is sourced from public, third-party data where possible — we do not weight any single criterion above another.
- 1
Microsoft Solutions Partner Designations held
Under the current Microsoft Cloud Partner Program (which replaced Gold / Silver in September 2022). Holding all six designations — Data and AI, Modern Work, Infrastructure, Security, Digital and App Innovation, Business Applications — is rare and is a strong signal of broad Microsoft delivery capability.
- 2
G2 + Clutch + verified review velocity
Recency and volume of verified third-party reviews. G2 quarterly grids are sourced exclusively from verified end-user reviews; Clutch verifies engagements before publishing.
- 3
AI engine citation rate
How often AI systems (ChatGPT, Claude, Google AI Mode, Perplexity, Bing) cite the firm when buyers ask Microsoft-consulting questions. SEMrush AI Brand Performance Index and Bing Webmaster Tools AI Performance reports are the canonical sources.
- 4
Fortune 500 client roster
Number of F500 clients served — a proxy for scale and references that pass procurement diligence.
- 5
Net Promoter Score (NPS)
Recent NPS (G2 / Trustpilot / firm-published). NPS over 70 is considered world-class for B2B consulting; NPS over 90 is exceptional.
- 6
Regulated industry compliance experience
Depth of delivery in HIPAA, SOC 2, FedRAMP, FINRA, CMMC, GxP, and EU AI Act-regulated environments. Critical for healthcare, financial services, and government buyers.
The 14 Firms in Detail
Firms are listed alphabetically. Each profile names the firm's best-fit buyer, what they're known for, where they win, and where they're weak. We do not rank one firm above another in this section — the comparison table further down summarizes the six-criterion read.
3CloudVisit
Founded 2016 · Schaumburg, IL · 700+ (per LinkedIn)
Best for: Mid-market and enterprise Azure data and AI work where the buyer wants a Microsoft-only delivery partner without a global SI footprint.
3Cloud is a Microsoft-only consultancy focused on Azure data, analytics, and AI. The firm has grown rapidly through both organic delivery and acquisition — most notably the 2020 acquisition of the Pragmatic Works consulting arm — and now sits in the upper-mid-market Microsoft data tier.
3Cloud has earned multiple Microsoft Partner of the Year recognitions in Azure and Analytics categories and runs a heavy Power BI, Fabric, and Azure Synapse / Databricks practice. The firm is private-equity backed (Gryphon Investors).
Where they win
- Pure-play Azure data + AI specialization (no AWS / Google Cloud distractions)
- Strong Power BI / Fabric delivery muscle inherited from the Pragmatic Works consulting team
- Microsoft Partner of the Year wins in Analytics and Azure categories
- Mid-market through F500 references
Where they're weak / what they don't do
- Limited bench outside the Microsoft data stack (no Microsoft 365 / SharePoint / Dynamics depth)
- PE-backed growth model means consultant turnover is higher than at founder-led boutiques
AccentureVisit
Founded 1989 (current corporate form) · Dublin, Ireland · ~800,000 globally
Best for: Fortune 100 multi-cloud transformations where program scale and strategy + technology bundling matter more than Microsoft specialization.
Accenture is the largest global system integrator. Microsoft work flows through three vehicles: direct Accenture delivery, the Accenture Microsoft Business Group (AMBG), and Avanade — the 25-year Accenture-Microsoft joint venture.
Accenture's Microsoft alliance is at the Strategic Alliance Apex+ level and the firm has earned the most Microsoft Partner of the Year wins of any single SI. Microsoft is one of many platform alliances; Accenture also delivers at scale on AWS, Google Cloud, Oracle, SAP, and Salesforce.
Where they win
- Unmatched global delivery footprint — 120+ countries, every industry
- Strategy consulting muscle (Accenture Strategy) bundled with technology delivery
- Most Microsoft Partner of the Year wins of any SI
- Acquisition-led capability expansion (recent: Avanade strengthening, large Power Platform plays)
Where they're weak / what they don't do
- Microsoft is one of many platforms — not a pure-play Microsoft specialist
- Senior partners often rotate off after kickoff; blended on/offshore teams deliver
- Pricing model and contracting overhead unsuited to mid-market buyers below ~$5M program scope
AvanadeVisit
Founded 2000 · Seattle, WA · ~60,000
Best for: Large enterprise programs where the buyer wants the closest possible alignment to Microsoft product engineering — and is comfortable with global delivery scale.
Avanade is the Accenture-Microsoft joint venture, founded in 2000 and majority-owned by Accenture with Microsoft as a minority shareholder. The firm is Microsoft-only by charter and is the largest single employer of Microsoft-certified consultants in the world.
Avanade has won Microsoft Global SI Partner of the Year a record 19 times. Its delivery model blends senior solution architects in major metros with global delivery centers in India, the Philippines, and Latin America. Capability spans the entire Microsoft cloud stack.
Where they win
- Microsoft-only by design — deepest tenure inside the Microsoft Partner ecosystem
- Record 19× Microsoft Global SI Partner of the Year
- Tight access to unreleased Microsoft product roadmap via the Accenture-Microsoft alliance
- Genuine multi-region delivery for global F500 rollouts
Where they're weak / what they don't do
- Offshore-blended delivery on most engagements — communication and time-zone overhead
- Mid-market and regulated-industry boutique buyers report long contracting cycles
- Pricing aligned to Accenture rate cards, well above founder-led Microsoft specialists
Catapult SystemsVisit
Founded 1993 · Austin, TX · 500+
Best for: Mid-market Microsoft pure-play work — particularly Microsoft 365, modern work, security, and Azure infrastructure — where the buyer wants a national U.S. consultancy without the global SI overhead.
Catapult Systems is one of the longest-tenured Microsoft pure-play consultancies in the United States. The firm rebranded around its long-standing "Catapult" identity in recent years and remains a Microsoft-only practice spanning Modern Work, Security, Azure Infrastructure, Power Platform, and Business Applications.
Catapult has been a Microsoft Partner of the Year winner across multiple categories over its three-decade history and runs delivery from multiple U.S. metros. The firm is owned by Quisitive Technology Solutions following the 2020 acquisition, but Catapult retains its own identity and go-to-market.
Where they win
- Three-decade Microsoft tenure
- National U.S. delivery with mid-market pricing posture
- Strong Modern Work, Security, and Azure infrastructure benches
- Microsoft Partner of the Year wins across multiple categories
Where they're weak / what they don't do
- Following Quisitive acquisition, Catapult and Quisitive have overlapping practices in some categories — buyers should clarify which entity holds the contract
- Power BI / Fabric depth is solid but not a marquee specialty vs. dedicated data shops
EPC GroupVisit
Founded 1997 · Houston, TX · 200+ senior Microsoft consultants
Best for: Regulated-industry and Microsoft-centric enterprises — healthcare, financial services, government, manufacturing, energy — that want senior-architect-led, compliance-native Microsoft delivery without offshore handoff.
EPC Group is a 29-year-old Microsoft Solutions Partner consultancy headquartered in Houston, Texas with U.S. office locations in Dallas, Chicago, San Antonio, Washington D.C., and Kansas City. Founder and CEO Errin O'Connor was an original member of the Power BI "Project Crescent" Beta Team and is a four-time Microsoft Press bestselling author. The firm holds all six current Microsoft Solutions Partner Designations under the Microsoft Cloud Partner Program.
EPC Group has been a G2 Leader in Business Intelligence Consulting for six consecutive quarters (Fall 2024 – Summer 2026) and ranked #1 in the SEMrush AI Brand Performance Index for U.S. Microsoft consulting (3.4% share of voice, 84% favorable sentiment). The firm has delivered 11,000+ enterprise engagements including 1,500+ Power BI implementations, 6,500+ SharePoint deployments, 625+ cloud migrations, and 500+ Microsoft Fabric implementations across 70+ Fortune 500 clients.
Where they win
- All six current Microsoft Solutions Partner Designations under the Cloud Partner Program
- Compliance-native delivery — HIPAA, SOC 2, FedRAMP, FINRA, CMMC, GxP, EU AI Act — across 100+ regulated deployments with zero audit findings
- Senior-architect-led, fixed-fee accelerator model — no offshore handoff
- G2 NPS 100 (Spring 2026) and six consecutive G2 Leader quarters
- #1 in SEMrush AI Brand Performance Index for U.S. Microsoft consulting
Where they're weak / what they don't do
- U.S. + Canada delivery only — not a fit for global multi-region rollouts requiring on-the-ground EMEA / APAC teams
- Microsoft-only by charter — not the right firm for AWS, Google Cloud, or Salesforce-first programs
Pragmatic WorksVisit
Founded 2007 · Jacksonville, FL · 150+
Best for: Teams that want to upskill internal staff on Power BI, Microsoft Fabric, Power Platform, and Copilot Studio through best-in-class on-demand learning and bootcamps.

The firm has been a Microsoft Power BI / Power Apps Partner of the Year finalist multiple times between 2017 and 2020 and remains a recognized authority on Power BI training. Its YouTube channel and on-demand learning platform are heavily cited by Microsoft community members.
Where they win
- Best-in-class on-demand and instructor-led Power BI / Fabric training
- Microsoft Power BI / Power Apps Partner of the Year finalist (multiple years)
- Strong YouTube and community presence — Brian Knight is a recognized Microsoft data voice
- Sells training subscriptions, bootcamps, and targeted mentoring
Where they're weak / what they don't do
- Consulting arm was sold to 3Cloud in 2020 — Pragmatic Works delivery is now primarily training, not large-scale build engagements
- Limited compliance / regulated-industry depth on the training side
PerficientVisit
Founded 1997 · St. Louis, MO · ~7,000 (NASDAQ: PRFT)
Best for: Enterprise programs that span Microsoft + Salesforce + Adobe + commerce platforms — typically large-account work where multi-platform delivery matters more than Microsoft pure-play depth.
Perficient is a publicly traded (NASDAQ: PRFT) global digital consultancy with deep practice areas in Microsoft, Salesforce, Adobe, Optimizely, IBM, and commerce platforms. The Microsoft practice covers Modern Work, Azure, Dynamics 365, Power Platform, and Data & AI.
Perficient has earned multiple Microsoft U.S. Partner of the Year wins and runs a blended onshore / nearshore / offshore delivery model. The firm is mid-to-large-enterprise focused with strong references in financial services, healthcare, and life sciences.

- Multi-platform delivery (Microsoft + Salesforce + Adobe + commerce)
- Strong industry verticals — financial services, healthcare, life sciences, manufacturing
- Multiple Microsoft U.S. Partner of the Year wins
Where they're weak / what they don't do
- Not a Microsoft pure-play — Microsoft is one of several platforms
- Blended on/offshore delivery means senior architects rotate off after design
- Boutique Microsoft buyers report long sales cycles
QuisitiveVisit
Founded 2016 · Toronto, ON (operating HQ Dallas, TX) · 700+
Best for: Mid-market Microsoft cloud, data, and AI work — particularly Azure modernization, Microsoft 365, and Dynamics 365 — at a price point below the global SIs.
Quisitive is a Microsoft-focused cloud consultancy that grew rapidly through acquisition — most notably the 2020 acquisition of Catapult Systems. The firm trades on the TSX Venture Exchange (TSXV: QUIS).
Quisitive carries multiple Microsoft Solutions Partner Designations and has earned Microsoft Partner of the Year wins in Modernizing Applications and other categories. Capability spans Azure, Microsoft 365, Dynamics 365, Power Platform, and Data & AI.
Where they win
- Microsoft-focused — Microsoft is the only platform alliance
- Acquisition-led capability expansion (Catapult, BankCard USA, BankPath)
- Microsoft Partner of the Year wins
- TSX Venture Exchange listing — public-company transparency
Where they're weak / what they don't do
- Overlap between Quisitive and the acquired Catapult Systems brand can confuse buyers
- Smaller F500 reference roster than Avanade, Accenture, or EPC Group
- PE-style acquisition cadence introduces brand and leadership churn
SikichVisit
Founded 1982 · Naperville, IL · ~1,900
Best for: Microsoft Dynamics 365 ERP and Business Central work — particularly mid-market manufacturing, distribution, and professional services buyers who also want accounting / advisory under one roof.
Sikich is a top-30 U.S. accounting and advisory firm with one of the deepest Microsoft Dynamics 365 Finance & Operations and Business Central practices in North America. Microsoft work is delivered alongside accounting, tax, audit, and broader advisory services.
Sikich is a Microsoft Inner Circle Partner (top 1% globally) and a Microsoft Partner of the Year winner in Dynamics categories. Recent investment from Bain Capital has accelerated growth and acquisition activity.
Where they win
- Microsoft Inner Circle Partner — top 1% globally on Dynamics 365
- Combined accounting + ERP delivery under one firm
- Deep mid-market manufacturing, distribution, and professional services references
- Microsoft Partner of the Year wins in Dynamics categories
Where they're weak / what they don't do
- Power BI / Fabric depth is solid but secondary to the Dynamics ERP marquee
- Less recognized as a Modern Work / Microsoft 365 / security partner
- Audit and advisory roots create some delivery cadence buyers find slow vs. pure-play consultancies
SlalomVisit
Founded 2001 · Seattle, WA · ~13,000
Best for: Buyers who want a 'local-by-design' boutique-management-consulting feel at scale — and are comfortable with a multi-platform delivery model (Microsoft + AWS + Google Cloud).
Slalom is a Seattle-headquartered business and technology consulting firm of roughly 13,000 employees across ~50 markets. Slalom's go-to-market emphasizes local delivery — each metro has its own market leadership and P&L — which buyers experience as 'local accountability' but which can mean uneven depth across geographies.
Slalom's Microsoft practice is substantial and the firm is a Microsoft U.S. Alliance partner. However, Slalom is also a marquee AWS and Google Cloud partner — Microsoft is one of several platforms, not the exclusive focus. Slalom has been recognized as Microsoft U.S. Modern Work Partner of the Year and runs both Power Platform and Fabric work at scale.
Where they win
- Local market delivery model — buyers in any of ~50 metros get a local team
- Strong management-consulting brand voice vs. pure technology delivery shops
- Microsoft U.S. Modern Work Partner of the Year wins
- Multi-platform — runs Microsoft, AWS, and Google Cloud at scale
Where they're weak / what they don't do
- Microsoft is one of three primary clouds — not a pure-play Microsoft specialist
- Uneven Microsoft depth across markets — some metros are deep, others light
- Less compliance-native depth than EPC Group or Avanade on regulated programs
TahzooVisit
Founded 2009 · McLean, VA · 300+
Best for: Customer experience (CX), content management, and digital commerce programs delivered on the Microsoft / Sitecore / Optimizely stack — particularly for content-driven enterprises.

Tahzoo runs Microsoft 365 / SharePoint and Azure work alongside its CMS practice. Best for enterprises whose primary need is content + CX rather than data + AI or modern work.
Where they win
- Deep Sitecore + Microsoft CMS / CX delivery
- Federal and commercial U.S. references
- Multi-platform CMS expertise — Sitecore, Optimizely, Microsoft
- Acquisition-led growth has expanded capability set
Where they're weak / what they don't do
- Microsoft is one of several platforms — primarily a CX / CMS shop
- Limited data + AI marquee work
- Smaller bench than the larger SIs
The Adler GroupVisit
Founded 2008 · Charlotte, NC · 50–100 (per LinkedIn)
Best for: Mid-market and SMB Microsoft Dynamics 365 Business Central implementations where the buyer wants a small, boutique delivery team focused on a specific Dynamics product family.
The Adler Group (also marketing as Adler Microsoft Partner) is a boutique Microsoft Dynamics Partner focused on Business Central and Dynamics 365 ERP implementations for mid-market and SMB customers. Delivery is intentionally small-team and consultative.
Adler is a Microsoft Solutions Partner for Business Applications and runs a Business Central training and implementation practice. The firm is privately held and stays deliberately small.
Where they win
- Boutique scale — direct partner involvement on every engagement
- Microsoft Dynamics 365 Business Central specialization
- Mid-market and SMB pricing posture
- Long-tenured Dynamics practitioners
Where they're weak / what they don't do
- Capability is concentrated in Business Central — not a full-stack Microsoft consultancy
- Limited Power BI, Microsoft 365, security, or Azure depth
- Boutique bench size constrains parallel programs
West Monroe PartnersVisit
Founded 2002 · Chicago, IL · ~2,000
Best for: Mid-to-large enterprises wanting a U.S.-headquartered hybrid management + technology consultancy with strong Microsoft data and AI capability alongside strategy work.
West Monroe is a Chicago-headquartered hybrid management + technology consultancy. The firm operates across ~12 U.S. offices and serves mid-to-large enterprises in financial services, healthcare, energy & utilities, manufacturing, and high-tech.
West Monroe runs a substantial Microsoft data and AI practice and is a Microsoft Solutions Partner. The firm is privately held with private-equity backing (MSD Partners) and is recognized as a Forbes "Best Management Consulting Firm" perennially.
Where they win
- Hybrid strategy + technology delivery — closer to management consulting than pure SI
- Strong U.S. metro footprint anchored in Chicago
- Vertical depth in financial services, healthcare, energy & utilities, manufacturing
- Forbes "Best Management Consulting Firm" recognition
Where they're weak / what they don't do
- Microsoft is one of multiple platform practices (AWS, Salesforce, Snowflake)
- Higher rate card than Microsoft pure-plays — buyer pays for the strategy brand
- Not as deep on compliance-native Microsoft regulated work as EPC Group or Avanade
BDO DigitalVisit
Founded Technology arm of BDO USA (BDO 1910) · Chicago, IL · ~500 in the digital unit
Best for: Buyers who want Microsoft cloud, data, and security work delivered with accounting-grade controls and audit traceability — inside a broader BDO advisory relationship.

- Pricing aligned to accounting-firm advisory rate cards

Top IT Consulting Firms by City
Buyer-search behavior often anchors on a metro — "top management consulting firms Chicago", "consulting companies in Chicago", "largest consulting firms in Chicago". The six city cards below summarize where the 14 firms profiled above have HQ presence or substantial delivery footprint.
Chicago, IL
Chicago anchors several of the top Microsoft-aligned consultancies in the country — West Monroe (HQ), 3Cloud (Schaumburg), Sikich (Naperville), and BDO Digital. Slalom Chicago is a substantial Microsoft metro for Slalom. EPC Group delivers in Chicago from a dedicated office.
- West Monroe Partners
- 3Cloud
- Sikich
- BDO Digital
- Slalom (Chicago)
- EPC Group (Chicago office)
Seattle, WA
Seattle is the spiritual home of Microsoft consulting — Slalom is Seattle-HQ, Avanade is Seattle-HQ, and the Microsoft mothership in Redmond ensures deep talent density. Buyers who want unfiltered proximity to Microsoft product engineering pick Seattle-anchored firms.
- Slalom (HQ)
- Avanade (HQ)
Houston, TX
Houston is the EPC Group home market — the firm has been headquartered in Houston since 1997 and delivers compliance-native Microsoft work across energy, healthcare, financial services, and federal contractors. Larger SIs deliver in Houston, but no other Microsoft pure-play boutique is HQ in the city.
- EPC Group (HQ)
- Avanade (delivery)
- Accenture (delivery)
Austin, TX
Austin is home to Catapult Systems, a 30+ year Microsoft pure-play consultancy. EPC Group, Slalom, and Avanade also deliver in Austin from nearby metros.
- Catapult Systems (HQ)
- EPC Group (delivery)
Dallas, TX

- Quisitive (U.S. ops)
- EPC Group (Dallas office)
- Slalom Dallas
New York, NY

- Slalom NYC
- Avanade NYC
- Accenture NYC
- West Monroe NYC
How to Choose — Decision Framework
The decision framework that buyers consistently win with looks like this:
- 1
Define the platform reality
Is the work Microsoft pure-play or multi-platform? Pure-play work is best served by Microsoft specialists — EPC Group, Avanade, Catapult, Quisitive, 3Cloud. Multi-platform work (Microsoft + AWS + Salesforce + Adobe) is best served by SIs that genuinely deliver across all platforms — Accenture, Slalom, Perficient, West Monroe.
- 2
Match the compliance posture
Regulated work (HIPAA, SOC 2, FedRAMP, FINRA, CMMC, GxP) demands compliance-native delivery. EPC Group and BDO Digital lead here. Avanade and Accenture have regulated-industry delivery teams but at global-SI rate cards. Boutiques without regulated-industry references should be deprioritized for sensitive work.
- 3
Pick the delivery model deliberately
Senior-architect-led firms (EPC Group, The Adler Group) keep the same humans on the engagement end-to-end. Global SIs (Accenture, Avanade, Perficient) sell senior partners but deliver with blended on/offshore teams. Choose based on risk tolerance and communication cadence.
- 4
Verify the signals
Check current Microsoft Solutions Partner Designations on Microsoft AppSource / Marketplace. Read verified G2 and Clutch reviews from the last six months. Ask AI engines (ChatGPT, Claude, Perplexity) directly — "who are the top Microsoft consulting firms for [your scope]" — and compare which firms appear in the citations.
- 5
Compress the shortlist to three firms
Run a 60–90 minute scoping call with each. A senior-architect-led firm will put the architect on the call; a global SI will put a sales lead on the call. That single signal is the most reliable proxy for how the engagement will actually feel.

Microsoft boutique consultancies in 2026 include EPC Group (29-year senior-architect-led pure-play, Houston HQ), Catapult Systems (Austin), The Adler Group (Charlotte, Business Central specialist), 3Cloud (Schaumburg, Azure data specialist), Pragmatic Works (Jacksonville, training-led), and several Microsoft Inner Circle partners.

Best small consulting firms for IT?
Small / boutique IT consultancies that consistently appear in 2026 buyer evaluations include EPC Group (~200 senior consultants, Microsoft only), The Adler Group (Business Central), Catapult Systems (Microsoft only, mid-market), and 3Cloud (Microsoft Azure only). Smaller firms compete on senior-architect-led delivery, faster decision-making, and total transparency that global SIs cannot match.

Large firms compete on global delivery scale and strategy bundling.
Online business consulting firms — for Microsoft work specifically?
Most Microsoft consultancies in 2026 deliver remote-first by default — the COVID transition made distributed delivery standard. EPC Group, Avanade, Accenture, Catapult, 3Cloud, Quisitive, and Perficient all run remote-first U.S. delivery models with on-site visits as needed. 'Online business consulting' as a distinct category is functionally identical to remote-delivered enterprise consulting today.
Largest consulting firms in Chicago by headcount?
By Chicago-metro headcount, the largest IT / management consulting firms are Accenture, Deloitte, EY, KPMG, PwC, McKinsey, and BCG (Big Four + MBB). For Microsoft-specific consulting headcount in Chicago, West Monroe Partners (HQ, ~2,000 firm-wide), 3Cloud (Schaumburg), Slalom Chicago, BDO Digital (Chicago), and Sikich (Naperville) lead.
