Shared Services Center
An internal organizational unit that consolidates common business support functions—finance, HR, IT, legal—into a single entity serving multiple business units, capturing scale efficiencies while maintaining internal control.
Full Definition
A Shared Services Center (SSC) consolidates transactional business support functions from dispersed business unit operations into a single dedicated internal entity that provides those services back to the enterprise at defined service levels. Common functions moved to SSC models include: accounts payable and receivable processing, payroll administration, general ledger and statutory reporting, HR transaction processing (onboarding, offboarding, benefits administration), IT help desk and infrastructure support, contract management, and legal entity administration. The SSC operates like an internal service provider—with SLAs, performance metrics, and explicit cost transparency—while remaining part of the company rather than an external vendor. The financial case for SSC consolidation rests on three levers: headcount efficiency (centralizing 10 separate 5-person finance teams into a single 35-person SSC captures scale by eliminating duplicate management layers and enabling specialization), process standardization (a single SSC can implement best-practice processes and automation that individual business unit operations cannot justify), and location optimization (SSCs are typically established in lower-cost domestic cities or nearshore locations rather than high-cost headquarters cities, generating labor cost savings without offshore management complexity). Fortune 500 companies consistently report 20-35% cost reduction from SSC implementations, driven primarily by headcount consolidation and process automation. SSC implementation is substantially more complex than organization chart changes suggest. The migration of transactional work from embedded business unit teams to a centralized SSC requires: comprehensive process documentation (often revealing that no two business units perform the same processes identically, requiring standardization before consolidation), ERP system harmonization (SSCs cannot serve multiple business units efficiently if each operates on different ERP instances), change management for business unit leaders who lose direct control of previously embedded resources, and SLA design that gives business units contractual assurance of service quality before they accept consolidation.
FAQs
How does a Shared Services Center differ from BPO?
A Shared Services Center is an internal organizational entity—the company owns it, employs its staff, and maintains direct management control. BPO transfers these same functions to an external third-party provider. SSCs retain institutional knowledge and control within the company; BPO introduces vendor dependency and contract complexity but typically provides additional cost savings through offshore labor arbitrage and provider scale. Many companies start with an internal SSC to capture consolidation benefits, then subsequently evaluate BPO for specific processes that benefit from external provider scale.
What are the most common SSC implementation failure modes?
Underestimating process complexity (discovering that standardization requires 12 months of work that was assumed to take 3), insufficient change management for business unit resistance (business unit leaders who feel service quality will decline resist giving up embedded resources), SLA design that fails to address business unit concerns (non-specific SLAs that don't address the critical performance dimensions business units care about), and IT infrastructure complexity (ERP consolidation or integration requirements that take significantly longer than projected, delaying SSC go-live and eroding projected savings timelines).
