IT consulting and systems integration is the business of helping enterprises design, build, and run technology — from migrating data centers to the cloud, to deploying AI agents, to maintaining legacy systems on multi-year contracts. The five companies here — Accenture (ACN), IBM (IBM, consulting segment only), Infosys (INFY), Cognizant (CTSH), and Wipro (WIT) — collectively employ roughly 1.9 million people and generated approximately $142 billion in combined IT services revenue in their most recent fiscal years. Revenue is earned primarily by billing for human hours (time-and-materials) or by running a client's technology environment on fixed-price managed-services contracts lasting one to five years.
Revenue is recurring (multi-year contracts), margins run 15-21%, and the business generates meaningful free cash flow. The offshore labor arbitrage — 70-80% of Indian IT workforce at $15K-$30K/year fully-loaded cost vs. $100K-$200K in the US — is the primary margin engine. est.
IT consulting firms sell three things, roughly in order of margin from lowest to highest:
The AI wave has added a fourth category: AI implementation services — building and deploying AI models, agents, and copilots inside enterprise environments. This spans prompt engineering, fine-tuning, retrieval-augmented generation (RAG), and agentic workflow automation. Accenture disclosed $2.7B of AI-specific revenue in FY2025 (tripled year-over-year) and $5.9B in AI bookings. IBM reported cumulative generative AI book of business exceeding $12.5B through end of 2025.
Indian IT services firms (Infosys, Wipro, Cognizant) have 70-80% of their workforce in India, where fully-loaded costs per engineer run roughly $15,000-$30,000/year versus $100,000-$200,000 in the US. est. The difference between what the client pays per hour and what the consultant costs, multiplied by utilization rate (typically 85-92%), determines margin. est.

Business Research Insights estimates the global IT consulting services market at approximately $83 billion in 2026, growing at a 6.5% CAGR through 2035 to $106 billion. est. Accenture's AI bookings roughly doubled year-over-year to $5.9B; Forrester reported $900M of GenAI deals in a single quarter (Q2 2025). Gartner projected worldwide AI spending of $1.5 trillion in 2025 across all categories. est.

In IT consulting, capacity is people. Utilization rate (percentage of available hours billed to clients) is the factory's uptime.
| Company | Employees | Voluntary attrition | Workforce note |
|---|---|---|---|
| ACN | 779,273 | 15.0% | AI/data workforce ~77,000 (up from ~40,000 at FY2023 start) |
| CTSH | 336,300 | 15.9% | Q1 2025 headcount; 10,700 quits in quarter |
| INFY | ~300,000+ est. | -- | Exact figure not disclosed in FY2025 results |
| IBM | ~270,000 est. | -- | Total company; consulting is one segment (~$21B of $67.5B revenue) |
| WIT | ~230,000+ est. | 15.0% | IT services revenue declined 2.7% YoY despite stable headcount |
Total headcount across all five: roughly 1.9 million. This is not a supply-constrained industry in aggregate -- large pools of engineering talent exist in India, Eastern Europe, Latin America, and Southeast Asia. These firms can hire tens of thousands of engineers per quarter when demand warrants it.
The constraint is the mix, not total headcount. Enterprises want AI architects, ML engineers, data engineers, and prompt engineers -- roles most of the existing 1.9 million consultants are not trained for. Accenture has scaled its AI/data workforce from ~40,000 to ~77,000 over two years, still only ~10% of its total. TCS reported 50 million employee hours invested in emerging-technology training.
This bottleneck is self-resolving in two ways: (1) internal AI tools multiplying per-person output -- one consultant with AI copilots may do work previously requiring three; and (2) the AI being deployed for clients will eventually reduce the need for consultants on many tasks. Short-term demand for AI implementation services is surging; the technology being implemented may eventually substitute for the implementers.

Accenture's AI bookings doubled to $5.9B and AI revenue tripled to $2.7B. Book-to-bill at 1.2x indicates backlogs growing faster than delivery capacity. Forrester observed AI increasingly embedded in traditional deals rather than sold standalone, meaning effective AI-related revenue is likely larger than what companies break out separately.
Coding copilots, automated testing, AI-driven documentation, and agentic workflows reduce human hours per project. If a team of 10 with AI tools can do what 30 did before, revenue per head rises but total headcount demand falls. IBM's consulting segment grew only 2% in FY2025 (flat in constant currency) despite the AI boom. Infosys guided 0-3% growth for FY2026; Wipro guided for sequential declines. Flat-to-low-single-digit growth trajectories during an AI demand surge suggest either productivity tools are compressing hours billed per engagement, or overall IT budget caution is offsetting AI-specific demand.
Overall industry pricing is stable to modestly rising. Indian IT firms compete heavily on cost, capping rate increases. Margins expanding slightly (Infosys +0.5pp YoY, Wipro +0.9pp) but not dramatically.

IBM is not a pure-play IT consultant. Its $67.5B revenue includes software ($30B, 44%) and infrastructure ($15.7B, 23%). Only the consulting segment ($21.1B, 31%) is comparable to the other four. IBM's market cap and P/E reflect the software business. IBM Consulting ($21.1B, +2% growth) vs. Cognizant ($21.1B, +7% growth): nearly identical revenue, different growth trajectories.
Accenture is the largest pure-play at $69.7B revenue -- roughly 3.5x each Indian peer. 77,000 AI-skilled workers, 6,000 AI projects, $5.9B AI bookings. Trailing P/E 14.5x (was 25-30x a year ago). Stock down ~38% in 12 months.
Cognizant trades at 11.6x trailing P/E (forward 9.2x est.), partly reflecting a $1B+ Q3 2025 tax charge. Revenue growth at 7% is the fastest among the pure consultants.
