TCS Beats Accenture to Win Best Buy India GCC Mandate Worth Around ₹2,000 Crore

Tata Consultancy Services has emerged ahead of Accenture to secure a five-year technology services mandate covering Best Buy’s India Global Capability Centre operations, in a deal estimated to be worth approximately ₹2,000 crore.

The mandate represents a significant expansion of TCS’s existing relationship with the US consumer-electronics retailer and extends beyond conventional IT services into strategically important areas including:

data,

analytics,

artificial intelligence,

and:

GCC operations.

Best Buy’s India technology centre is located in Bengaluru and employs around 600 people.

The retailer established the centre as an innovation hub supporting its broader digital transformation, and its strategic importance has increased as Best Buy invests more heavily in AI, mobile platforms, personalisation and digital commerce.

TCS reportedly secured the mandate after a competitive request-for-proposal process in which Accenture reached the final stage, while Wipro was also part of the initial shortlist.

The win illustrates a broader change in India's GCC market as major technology-services companies increasingly compete not simply to provide outsourced IT services but to operate and transform critical technology functions inside multinational companies’ capability centres.

TCS Wins Five-Year Best Buy Technology Mandate

The Best Buy engagement is expected to run for:

five years.

The estimated contract value is approximately:

₹2,000 crore.

Importantly, the ₹2,000 crore figure is an industry estimate rather than a contract value formally disclosed by the companies.

The mandate covers Best Buy's India GCC operations alongside a wider technology-services portfolio.

Areas covered include:

data,

analytics,

artificial intelligence,

and other technology capabilities supporting Best Buy's digital operations.

This makes the engagement considerably broader than a conventional infrastructure-maintenance outsourcing contract.

TCS will be positioned closer to technology functions that can directly influence Best Buy's customer experience, digital-commerce capabilities and future AI strategy.

TCS Emerges Ahead of Accenture

Best Buy selected its technology partner through a competitive RFP process.

TCS and Accenture reportedly emerged as the final contenders.

TCS ultimately secured the mandate, with factors including:

competitive pricing,

service-level commitments,

and:

productivity benefits

playing an important role in the selection.

Wipro was also understood to have participated during the earlier stages of the process.

The competition demonstrates how valuable large GCC mandates have become for technology-services companies.

Winning responsibility for a client's capability centre can create a significantly deeper relationship than providing isolated technology projects.

Best Buy's Bengaluru GCC Employs Around 600 People

At the centre of the engagement is Best Buy's Bengaluru technology operation.

The GCC currently employs approximately:

600 people.

Best Buy established its Bengaluru technology centre in 2024 as part of its broader digital-transformation strategy.

The facility spans approximately:

70,000 square feet.

It was designed as an innovation hub rather than simply a conventional back-office operation.

Its mandate spans areas including:

digital strategy,

product management,

design,

engineering,

technology infrastructure,

and operations.

That makes the Bengaluru centre an important component of Best Buy's global technology organisation.

Best Buy Wants India Hub at Heart of Innovation

Best Buy's ambitions for the Bengaluru centre have been clear since its establishment.

The retailer positioned India as an important technology and innovation location, particularly around:

mobile platforms

and:

artificial intelligence.

The centre has consequently become increasingly important as Best Buy develops new digital capabilities.

The company's technology priorities now extend across areas including:

AI-enabled customer experiences,

personalisation,

digital commerce,

mobile engagement,

data,

and technology infrastructure.

The TCS mandate therefore places the Indian IT company inside an increasingly strategic part of Best Buy's operating model.

Deal Deepens Existing TCS-Best Buy Relationship

Best Buy is not an entirely new client for TCS.

The Indian technology company already has an established relationship with the US retailer spanning:

technology services

and:

digital transformation.

The new GCC mandate expands that relationship.

Rather than supporting only individual technology programmes, TCS is expected to assume responsibility for a broader portion of Best Buy's technology environment in India.

That creates opportunities for TCS to participate in additional transformation initiatives as Best Buy increases its adoption of AI and advanced analytics.

Large existing client relationships are particularly important for IT-services companies because they can expand progressively across technologies and business functions.

Existing Relationship Estimated at $75–100 Million Annually

HFS Research CEO Phil Fersht has estimated that the existing relationship between TCS and Best Buy could represent approximately:

$75 million to $100 million in annual revenue.

However, there is no publicly disclosed contract value for the broader existing relationship.

The estimate illustrates the potential scale of Best Buy as a TCS client.

The new GCC mandate could further strengthen TCS's position within the account and create additional opportunities as the retailer modernises its technology estate.

For TCS, expanding business with existing multinational customers can be strategically attractive because the company already understands the client's technology environment and operational requirements.

Best Buy Is Increasing Investment in AI

Artificial intelligence is becoming an increasingly important component of Best Buy's digital strategy.

The retailer has identified AI as a major technology priority for fiscal 2027.

Its ambitions extend beyond using AI internally.

Best Buy is also exploring how artificial intelligence can reshape the consumer-shopping journey.

Potential applications include:

product discovery,

personalised recommendations,

customer support,

digital shopping,

inventory intelligence,

and more seamless purchasing experiences.

The retailer is also working toward technology experiences in which customers can interact with AI-enabled platforms to discover and purchase products.

This makes data architecture, analytics and AI capabilities increasingly important to Best Buy's competitive strategy.

India GCC Could Support Agentic Commerce Strategy

One emerging area of retail technology is:

agentic commerce.

Traditional ecommerce requires consumers to navigate websites or applications, search for products, compare options and complete transactions.

AI agents could increasingly perform parts of that journey on behalf of customers.

That could include:

understanding customer requirements,

searching catalogues,

comparing products,

providing recommendations,

and assisting with purchasing decisions.

For retailers such as Best Buy, supporting this model requires sophisticated integration across:

product catalogues,

pricing,

inventory,

customer data,

payments,

AI models,

and digital interfaces.

A technology centre with strong AI, data and engineering capabilities can therefore become increasingly central to the retailer's future operating model.

Best Buy Generated $41.7 Billion in FY2026 Revenue

The scale of the client makes the mandate particularly significant.

Best Buy generated approximately:

$41.7 billion in revenue during fiscal 2026.

That compared with around:

$41.5 billion

in the previous fiscal year.

Comparable sales increased approximately:

0.5%.

Computing and mobile-phone categories contributed to growth, while weaker performance in areas including home theatre and appliances partly offset those gains.

Technology investment is particularly important for large retailers operating in mature markets because improvements in digital conversion, customer engagement and personalisation can have meaningful commercial effects at scale.

GCCs Are Becoming Strategic Technology Hubs

The Best Buy mandate reflects a larger transformation underway across India's Global Capability Centre industry.

Historically, many multinational companies established Indian centres primarily for:

back-office operations,

IT support,

shared services,

and cost optimisation.

That model has changed significantly.

Modern GCCs increasingly handle:

software engineering,

product development,

cybersecurity,

cloud architecture,

data science,

artificial intelligence,

finance,

research,

and global business operations.

In some multinational companies, Indian GCCs now own complete global products or technology functions.

This shift has created a new opportunity for Indian IT-services companies.

IT Companies Are Developing GCC-as-a-Service Models

Large technology-services providers increasingly see GCCs as a major growth market.

Instead of viewing captive centres as competitors for outsourced technology work, IT companies can help multinational businesses:

establish GCCs,

operate them,

scale teams,

modernise technology,

manage infrastructure,

and eventually transform their capabilities.

This creates a hybrid model between:

traditional outsourcing

and:

fully captive operations.

A multinational company retains strategic control while an external technology provider contributes operating scale, specialised skills and transformation capabilities.

The Best Buy-TCS mandate demonstrates how this model can work at a substantial scale.

TCS Gains Strategic Position Inside Client Technology Estate

The significance of the contract extends beyond its estimated ₹2,000 crore value.

Operating a client's GCC can place a technology provider closer to the client's:

leadership teams,

technology architecture,

product roadmap,

data environment,

and innovation priorities.

That position can create opportunities for future work.

For example, a provider managing GCC operations could potentially expand into:

cloud modernisation,

AI deployment,

data platforms,

cybersecurity,

enterprise applications,

automation,

and customer-experience transformation.

The commercial value of a GCC relationship can therefore extend beyond the initial mandate.

AI Is Changing the Economics of IT Services

The deal also arrives as artificial intelligence reshapes the traditional IT-services business model.

Historically, large technology contracts often depended heavily on:

headcount,

offshore delivery,

application maintenance,

and labour-cost advantages.

Generative AI and automation are changing that equation.

Clients increasingly expect providers to deliver:

higher productivity,

greater automation,

faster software development,

and measurable business outcomes.

That makes productivity commitments increasingly important during competitive technology-services bids.

The reported role of productivity benefits in TCS winning the Best Buy mandate reflects this wider shift.

Pricing Remains a Major Competitive Factor

Competitive pricing also reportedly contributed to TCS's success.

Large technology contracts often involve intense competition because even small differences in commercial terms can have substantial financial consequences across multi-year agreements.

For providers, however, winning a large deal at an attractive headline value is only part of the equation.

The contract must also generate acceptable margins.

That requires disciplined management of:

staffing,

automation,

delivery locations,

technology investments,

and service commitments.

TCS will therefore need to balance competitive commercial terms with operational efficiency throughout the five-year engagement.

Service-Level Agreements Become More Important

Aggressive service-level agreements were another reported factor behind the selection.

SLAs define measurable expectations for technology-service delivery.

Depending on the engagement, they can cover:

system availability,

response times,

incident resolution,

performance,

quality,

delivery milestones,

and other operating metrics.

For a strategically important GCC, service levels can become particularly demanding because technology failures can affect customer-facing systems and business operations.

Meeting these commitments consistently will be central to the long-term success of the Best Buy engagement.

Deal Highlights TCS-Accenture Competition

The final-stage competition between TCS and Accenture also illustrates the increasingly global nature of the technology-services market.

Indian IT companies no longer compete only against one another.

They compete directly with global consulting and technology groups across:

cloud,

data,

AI,

enterprise transformation,

managed services,

and GCC operations.

At the same time, a single large client can work with multiple providers.

Winning one mandate therefore does not necessarily remove other technology companies from the account.

Different providers can retain responsibility for different parts of a client's technology and transformation portfolio.

GCC Opportunity Could Become Larger for Indian IT Industry

India has become one of the world's most important locations for multinational capability centres.

The country's advantages include:

a large technology workforce,

deep engineering capabilities,

established IT infrastructure,

a mature outsourcing ecosystem,

and extensive experience serving international companies.

As GCCs move toward higher-value work, Indian technology companies have an opportunity to provide specialised services around them.

This can include:

build-operate-transform models,

talent management,

AI engineering,

cloud operations,

cybersecurity,

enterprise platforms,

and digital product development.

The Best Buy mandate provides another example of how the GCC ecosystem can create business for technology-services providers rather than simply shifting work away from traditional outsourcing.

Conclusion

TCS's reported ₹2,000 crore Best Buy mandate represents more than another large outsourcing contract.

The five-year engagement places TCS at the centre of Best Buy's Bengaluru GCC operations and broader technology portfolio spanning data, analytics and artificial intelligence.

TCS emerged ahead of Accenture during the final stage of a competitive selection process, with pricing, service-level commitments and productivity benefits reportedly contributing to the win.

The mandate also deepens an existing TCS-Best Buy relationship as the US retailer increases investment in AI, digital commerce and customer personalisation.

More broadly, the deal illustrates the changing relationship between India's IT-services industry and the country's rapidly expanding GCC ecosystem.

Rather than treating multinational capability centres simply as competitors for technology work, major IT providers are increasingly positioning themselves as partners that can operate, scale and transform those centres.

For TCS, Best Buy's Bengaluru hub offers exactly that opportunity: a position inside a strategic technology operation that could become increasingly important as retail moves deeper into an AI-driven era.
