Shared Services Strategy And GRC Considerations: Lessons From Buenos Aires As A Regional Hub
The Strategic Logic Of Shared Services Centers
Organizations pursue shared services strategies to achieve three interrelated objectives: the integration of fragmented operational processes across business units and geographies, the consolidation of transactional activities into centralized operations that benefit from scale and specialization, and the standardization
of processes to eliminate duplication, reduce variation, and enable
continuous improvement. These objectives are not new. They reflect the
fundamental operational principle that repetitive, rules-based,
high-volume transactional activities can be performed more efficiently
and more consistently when they are concentrated in purpose-built
operations rather than distributed across multiple business units, each
with its own processes, systems, and staffing models.
The functions most commonly migrated to shared services centers include finance and accounting
(accounts payable, accounts receivable, general ledger, fixed assets,
intercompany accounting, financial reporting, and tax compliance
support), human resources and payroll (employee data management, payroll processing, benefits administration, and recruitment support), information technology (infrastructure management, application support, help desk operations, and development services), procurement (purchase order processing, vendor management, and invoice verification), and supply chain support (logistics coordination, inventory management, and order fulfillment support).
The
migration of these functions from corporate headquarters and local
subsidiaries to a shared services center follows a structured transition
process. Activities are documented and mapped in their current state,
redesigned for standardization and efficiency, migrated to the shared
services operation, and then continuously improved through process
optimization, automation, and performance measurement. The objective is
not merely to relocate activities to a lower-cost location but to fundamentally improve the quality, consistency, and efficiency of the processes through standardization and scale.
Location Selection: The Factors That Determine Success
The
selection of a shared services center location is one of the most
consequential decisions in the shared services strategy because location
determines the labor market available for staffing, the cost structure
of the operation, the regulatory and tax environment, the infrastructure
quality, the time zone alignment with supported operations, and the
operational risk profile of the center.
The factors that organizations typically evaluate in location selection include the following.
Labor market quality and availability.
The shared services operation requires a sustained supply of qualified
professionals with the functional expertise, language capabilities, and
educational background needed to perform the center's activities. For
finance and accounting shared services, this means professionals with
training in accounting principles, familiarity with the relevant
accounting standards such as US GAAP or IFRS, and the analytical
capabilities needed for financial reporting and analysis. For IT shared
services, this means professionals with the relevant technical
certifications, programming skills, and systems knowledge. The depth of
the local labor market, the quality of local educational institutions,
and the competition from other employers for the same talent pool
directly affect the center's ability to recruit, retain, and develop its
workforce.
Language capabilities. Shared
services centers that support multi-regional operations require staff
who can communicate effectively in the languages of the regions they
serve. Centers serving Latin American, North American, and Southern
European operations benefit from a labor market with strong bilingual English and Spanish capabilities, and in some cases trilingual capabilities including Portuguese or Italian.
Cost competitiveness.
Labor costs represent the largest component of shared services
operating costs, and the differential between labor costs in the shared
services location and the locations from which the activities are
migrated is a primary driver of the financial business case. However,
cost should be evaluated on an all-in basis that
includes not only direct compensation but also social charges, benefits,
facilities, technology infrastructure, management overhead, and the
transition costs associated with migration and stabilization.
Time zone alignment.
Shared services centers that support operations in multiple regions
benefit from time zone positions that enable overlap with the business
hours of the regions they serve. A location positioned between the time
zones of Europe and North America, for example, can provide real-day
support to both regions without requiring extensive shift work.
Infrastructure quality.
The physical and telecommunications infrastructure of the location
determines whether the center can operate reliably, securely, and with
the connectivity required for real-time system access and communication
with supported operations. Power reliability, internet connectivity,
office space availability, and transportation infrastructure for
employee commuting all affect operational viability.
Regulatory and business environment.
The local legal, regulatory, tax, and labor law environment affects the
center's operating costs, its flexibility in staffing and
organizational design, and its compliance obligations. Employment law
provisions regarding termination, working hours, collective bargaining,
and social security contributions vary significantly across
jurisdictions and directly affect the center's cost structure and
operational flexibility.
Quality of life and cultural alignment.
The ability to attract and retain talent is affected by the quality of
life in the center's location, including safety, healthcare, education,
cultural amenities, and the overall living standard. Cultural alignment
between the shared services workforce and the headquarters and
subsidiary cultures that the center supports facilitates communication,
reduces friction, and improves the quality of service delivery.
Buenos Aires
has been selected by numerous multinational organizations as a location
for shared services centers serving regional and global operations. The
city's selection reflects its strong position across multiple location
factors, including a large and well-educated professional workforce,
widespread bilingual English and Spanish language capabilities,
competitive labor costs relative to North American and European
alternatives, favorable time zone positioning between European and North
American business hours, well-developed commercial infrastructure, and a
cultural orientation that aligns with Western European and North
American business practices. Major energy companies, technology firms,
consumer goods companies, professional services firms, and industrial
conglomerates have established shared services operations in Buenos
Aires to support finance and accounting, HR, IT, procurement, and
customer service functions across Latin American, North American, and
European operations.

The GRC Perspective On Shared Services
From
a governance, risk management, and compliance perspective, shared
services centers create both opportunities and risks that the GRC
framework must address.
The governance opportunity is that centralization enables the organization to implement consistent processes, controls, and policies
across the activities performed by the shared services center. When
accounts payable processing is performed in twenty different
subsidiaries, each with its own process variations, system
configurations, and control practices, the organization's control
environment is inherently inconsistent and difficult to audit. When the
same activity is performed in a shared services center with a single
standardized process, a common system configuration, and a unified
control framework, the control environment is more consistent, more
auditable, and more amenable to continuous improvement.
The compliance opportunity
is that centralization creates a single point at which regulatory
compliance requirements can be embedded into standard processes. A
shared services center that processes invoices for multiple
jurisdictions can implement anti-corruption screening, sanctions
checking, and tax compliance validation as standard steps in the
centralized process, ensuring that every transaction passes through the
same compliance controls regardless of which business unit or
jurisdiction originated the transaction.
The risk management opportunity
is that the concentration of transactional data in a shared services
operation creates a rich data environment for analytical monitoring,
exception detection, and continuous auditing. The earlier posts on
detecting illegal payments, SAP transaction codes for auditing, and
continuous controls monitoring all described analytical techniques that
are more effective when applied to centralized data than to fragmented
data distributed across multiple systems and locations.
However, shared services also create specific risks that the GRC framework must address.
Concentration risk
arises from the dependence of multiple business units and regions on a
single operational center. A disruption to the shared services center,
whether from a technology failure, a natural disaster, a political or
economic event in the host country, a pandemic, or a labor action, can
simultaneously affect all of the business units and functions that the
center supports. Business continuity planning for shared services
centers must address these concentration risks through redundancy
arrangements, geographic diversification, and defined recovery
procedures.
Segregation of duties risk may be
elevated in shared services environments because the standardization and
efficiency objectives of shared services can conflict with the
separation of functions required for effective internal controls. When a
shared services center processes high volumes of transactions with a
relatively small number of specialized staff, the pressure to maintain
processing efficiency can lead to the assignment of incompatible
functions to the same individual. The earlier post on segregation of
duties conflicts in SAP addressed the specific transaction combinations
that create SoD risk, and these conflicts must be specifically evaluated
in the shared services context where staffing constraints may create
pressure to consolidate functions.
Data privacy and cross-border data transfer risk
arises when the shared services center processes personal data,
financial data, or other sensitive information for operations in
jurisdictions with data protection regulations that restrict the
cross-border transfer of such data. The GDPR in Europe, the LGPD
in Brazil, and numerous other data protection laws impose specific
requirements on the transfer of personal data to jurisdictions that may
not be deemed to provide adequate data protection. Organizations must
ensure that their shared services arrangements comply with applicable
data transfer requirements, including the use of standard contractual
clauses, binding corporate rules, or other approved transfer mechanisms.
Regulatory compliance risk
in the local jurisdiction affects the shared services center itself.
Employment law, tax obligations, social security requirements, and local
regulatory obligations apply to the center's operations and workforce,
and the organization must maintain compliance with these requirements
alongside the compliance obligations of the regions it serves.
Service quality and transition risk
arises during the migration of activities from business units to the
shared services center. The transition period, during which activities
are being transferred, staff are being trained, and the new processes
are stabilizing, represents a period of elevated operational risk.
Transaction processing errors, reporting delays, and control gaps are
common during transition and must be managed through structured
transition governance, parallel processing, and enhanced monitoring
during the stabilization period.
Vendor and third-party risk
applies when the organization supplements its shared services workforce
with outsourced or contracted resources. The earlier posts on FCPA
audit procedures and global compliance program design addressed the
compliance obligations associated with third-party relationships, and
these obligations apply with equal force to outsourced resources within
the shared services operation.
Internal Audit And Assurance Over Shared Services
Internal
audit plays a critical role in providing assurance over shared services
operations. The centralization of transactional activities into a
single operation creates both the opportunity for efficient audit
coverage and the obligation to ensure that the concentrated activities
are adequately controlled.
Scope of assurance.
Internal audit should provide assurance over the design and operating
effectiveness of the controls embedded in the shared services center's
processes, the adequacy of segregation of duties within the center, the
security of the technology environment including ERP access controls and
data protection measures, the quality of the transition and
stabilization process for newly migrated activities, and the center's
compliance with applicable local regulations and with the organization's
global policies.
Coordination with external audit.
When the shared services center performs financial accounting and
reporting activities that are relevant to the organization's
consolidated financial statements, the external auditor must evaluate
the controls at the shared services center as part of the audit of
internal control over financial reporting. Internal audit should
coordinate its shared services audit coverage with the external auditor
to ensure consistent coverage, avoid duplication, and share relevant
findings. This coordination is consistent with the assurance mapping
principles discussed in the earlier post on coordinating risk oversight.
SOX compliance considerations.
For organizations subject to SOX Section 404, the controls performed by
the shared services center are within the scope of management's
assessment of internal control over financial reporting. The key
controls over accounts payable, accounts receivable, general ledger,
fixed assets, and financial reporting that are performed by the shared
services center must be documented, tested, and assessed for operating
effectiveness. The earlier posts on key controls versus non-key controls
and on what SOX auditors test in SAP provide the frameworks for
determining which shared services controls are key and how they should
be tested.
Continuous monitoring. The concentration of transactional data in a shared services operation creates ideal conditions for continuous controls monitoring,
as discussed in the earlier post on integrating GRC controls through
business intelligence. Automated monitoring of transaction patterns,
exception rates, processing timeliness, and control effectiveness
indicators can provide real-time assurance over the shared services
operation and can identify emerging control weaknesses or process
deterioration before they produce material errors or losses.
The Strategic Decision: Build, Partner, Or Outsource
Organizations
establishing shared services operations must decide whether to build
and operate the center with their own employees (captive shared services), to partner with a third-party provider that operates the center under the organization's direction (managed services), or to outsource the activities entirely to a business process outsourcing provider (BPO).
Each model carries different implications for governance, risk management, and cost structure. Captive shared services
provide the greatest control over processes, data, personnel, and the
control environment, but require the organization to invest in
facilities, technology, management, and local operational expertise. Managed services
transfer operational responsibility to a partner while retaining
varying degrees of control and oversight, but introduce vendor
management complexity and dependency risk. BPO provides
the most immediate cost benefit and scalability but creates the
greatest governance, compliance, and data security challenges because
the organization's transactional activities are performed by an external
party with its own processes, systems, and control environment.
The
GRC implications differ significantly across these models. Captive
shared services centers are subject to the organization's own governance
framework and control standards, and internal audit has direct access
to the operation. BPO arrangements introduce the need for service organization control reports
(SOC 1 Type II reports, formerly SAS 70) to provide assurance over the
controls at the service organization, the establishment of contractual
service level agreements and right-to-audit provisions, and the
implementation of vendor risk management and oversight processes.
The
selection among these models should be informed by the organization's
risk appetite, its capability to manage third-party relationships, the
sensitivity of the activities being centralized, the regulatory
requirements of the jurisdictions involved, and the organization's
strategic assessment of whether shared services management is a core
competency that should be retained or a support function that can be
effectively delegated.
From Operational Efficiency To Governance Advantage
Shared
services centers, when designed and governed effectively, provide
benefits that extend well beyond the cost savings that typically justify
the initial investment. The standardization of processes creates a more
controllable and auditable operational environment. The centralization
of transactional data creates opportunities for analytical monitoring
that are impractical in distributed operations. The concentration of
specialized expertise creates a professional community that can develop
deeper functional knowledge and more effective control practices than
individual business units can achieve independently.
However, these benefits are realized only when the shared services strategy is accompanied by a governance framework
that addresses the concentration risks, the compliance obligations, the
data protection requirements, and the control environment challenges
that centralization creates. A shared services center that achieves cost
savings while introducing segregation of duties conflicts, data
transfer violations, or business continuity vulnerabilities has not
achieved a net improvement in the organization's risk profile.
The
organizations that derive the greatest strategic value from shared
services are those that treat the governance and risk management
dimensions of the shared services strategy with the same rigor as the
operational and financial dimensions, and that view the shared services
center not merely as a cost-reduction mechanism but as a platform for control environment improvement, compliance standardization, and analytical capability development that strengthens the organization's GRC framework as a whole.
What Companies Typically Look For In An SSC Or BPO Location
When companies evaluate a location for shared services or outsourcing, they usually look at a combination of factors.
They
assess whether the labor market provides sufficient talent in finance,
accounting, IT, operations, and language support. They examine whether
the workforce can operate in multilingual environments and support
international service standards. They consider communications
infrastructure, business continuity, cybersecurity readiness, and
operational resilience. They also look at wage competitiveness, labor
flexibility, management depth, regulatory complexity, inflation
exposure, tax conditions, and the practical ease of building or scaling
an operation.
Buenos Aires has often been considered attractive
because it can support relatively sophisticated business services while
offering strong professional talent and useful geographic positioning.
That said, any location assessment should also consider macroeconomic
volatility, labor market dynamics, currency issues, and operational
risk. No location is attractive on strengths alone.
Ranked Outsourcing Companies
Why Finance And Accounting Work Often Moves First
Finance
and accounting are among the most common functions to migrate into
shared services models because the work is process intensive, scalable,
and highly sensitive to standardization. Activities such as accounts
payable, accounts receivable, billing, reconciliations, fixed assets,
intercompany accounting, payroll support, close support, reporting
preparation, and master data maintenance are all well suited to
centralization when processes are stable enough and control design is
strong.
Argentina has historically been attractive for this type
of work because of the depth of accounting and finance talent and the
ability to support multinational processes in both regional and cross
regional settings. In some cases, organizations also use such hubs for
internal control support, SOX related documentation, reporting
analytics, and selected audit support services.
The control
implication, however, is important. A finance SSC is not just an
efficiency platform. It becomes part of the internal control
environment. That means service design, governance, escalation, access
controls, supervision, and process ownership all need to be clear from
the start.
What A Strong Shared Services Strategy Should Actually Achieve
Many
organizations describe shared services in terms of cost reduction. That
is too narrow. A mature SSC strategy should aim to improve process
quality, increase standardization, strengthen data consistency, reduce
local fragmentation, improve service levels, and create a clearer basis
for automation and control monitoring.
Done well, shared services
can streamline handoffs, reduce non value added activity, improve
control visibility, and support stronger process ownership across
geographies. Done poorly, they can simply centralize broken processes,
create distance from the business, and introduce new operational,
conduct, and compliance risks.
That is why the strongest SSC
designs are built around service architecture, controls, governance, and
customer orientation rather than labor arbitrage alone.
Why Governance And Control Matter In Location Decisions
A
common weakness in outsourcing and shared services decisions is that
organizations focus heavily on cost and talent while underestimating
governance and risk. This is especially dangerous in finance, payroll,
procurement, HR, and IT support activities where process errors can
quickly become financial reporting issues, data protection incidents,
compliance failures, or operational disruptions.
When evaluating a
location or provider, companies should assess not only service capacity
but also business continuity, access governance, data privacy controls,
fraud risk, legal enforceability, regulatory exposure, incident
response capability, internal control maturity, and the quality of
management oversight. They should also understand whether key controls
remain with the business, move into the SSC, or become split across
teams in ways that create accountability gaps.
This is
particularly relevant in any location with macroeconomic volatility or
evolving regulatory conditions. The right response is not to avoid such
environments automatically. It is to design the control model with that
reality in mind.
Why Buenos Aires Has Been Used For More Than Basic Back Office Work
One
of the more important insights in your original draft is that Buenos
Aires has not only supported transactional processing, but also more
skilled work. That remains an important point.
In many cases,
operations based in Buenos Aires have supported multilingual service
delivery, financial reporting support, intercompany processes,
procurement support, data analysis, IT support, internal control related
activities, and regional or cross regional customer operations. This is
one reason the city has remained relevant. It is not only a low cost
processing location. It has often been used as a talent platform for
broader business support.
The more credible way to state this in a
timeless article is not to anchor the argument in the headcount of
specific companies at a specific moment. It is to note that a range of
multinational companies across energy, technology, consumer, logistics,
industrial, and professional services sectors have historically used
Buenos Aires as part of their global service delivery footprint.
What Types Of Services Are Most Commonly Supported
The
service mix typically associated with Buenos Aires and similar hubs
includes finance and accounting support, payroll and HR administration,
data processing, procurement support, reporting services, customer
support, IT support, analytics, and selected professional service
activities.
Finance and accounting services often include billing,
payment processing, reconciliations, reporting preparation, fixed asset
support, close support, intercompany accounting, and control
documentation. Back office support may include data entry, document
management, CRM support, order administration, and service desk work. IT
related support may range from staff augmentation and application
support to selected managed services or development support depending on
the operating model.
The specific service mix depends heavily on
the maturity of the company’s process model and the complexity it is
willing to centralize.
What Organizations Should Watch Closely
A balanced thought leadership view should also address the watchpoints.
Companies
using Buenos Aires or any similar location should pay close attention
to inflation and currency effects, wage competitiveness over time,
retention in critical skill pools, regulatory and tax changes, data
transfer requirements, labor law considerations, and concentration risk
if too much work is centralized in one city or region.
They should
also examine whether the service model has enough resilience. A
location may appear efficient in steady state but become fragile if the
company has not built adequate continuity planning, leadership depth,
process documentation, and cross training.
This is where GRC
leaders should be active. Outsourcing and shared services decisions are
operating model decisions, but they also have direct implications for
internal control, data governance, resilience, and compliance.
Why The Decision Should Be About Operating Model Fit, Not Only Cost
The
strongest companies do not ask only whether a location is cheaper. They
ask whether it is the right fit for the work, the control environment,
the talent model, and the customer service expectations they need to
support.
In some cases, Buenos Aires may be highly attractive for
finance, multilingual support, analytics, and professional back office
work. In other cases, the right answer may be a more diversified hub
model across several locations. The decision should be based on service
criticality, risk appetite, continuity needs, and the maturity of the
company’s process architecture.
That is the difference between tactical outsourcing and strategic shared services design.
Final Perspective
Buenos
Aires has remained relevant as a shared services and outsourcing
location because it offers more than labor cost advantage. It has
historically provided educated talent, language capability, and the
ability to support relatively sophisticated business processes for
multinational organizations.
The strategic question for companies
is not simply whether the city is attractive in general. It is whether
the location fits the specific service model, control requirements,
resilience expectations, and governance design the company needs.
That is how location strategy becomes part of enterprise operating model design rather than just a sourcing decision.
