Shared Services

Shared services is an in-house model where one team runs repeatable work, such as finance, HR, IT and procurement, for every business unit from a single center. The parent firm keeps control and payroll, and each unit pays for what it uses.

The idea took hold in the early 1990s, when General Electric and Ford pulled scattered finance teams into single sites to standardize ledgers and cut headcount. Three decades on, the playbook still works — what changed is the scope.

Today a center can absorb almost any rules-based function a corporation runs, from invoice processing to master-data management to first-line IT support. Most large groups also run a hybrid: a captive hub offshore, with selective vendor work layered on top.

Outsource Accelerator has tracked this shift since 2017, and one pattern keeps repeating. Companies that treat shared services as a pure cost play stall around year two. The ones that treat it as a process-redesign program keep compounding savings.

Key takeaways

• Shared services centralizes back-office work inside the company; outsourcing hands the same work to an outside vendor.
• Mature centers report 25–40% lower process costs once consolidation and standardization finish, per Deloitte’s 2023 Global Shared Services and Outsourcing Survey.
• Most large enterprises run hybrid setups: captive centers in Manila, Krakow or Bengaluru, plus targeted outsourcing on top.
• Governance is the make-or-break variable, not location — a center without a business-unit steering committee drifts into order-taking.
• Automation sits inside the model rather than replacing it, so staff shift from processing work to exception handling and analytics.

How it works

A shared services center (SSC) pulls similar tasks from every business unit into one team that works to a service-level agreement. Work gets standardized, automated where it can be, and charged back per transaction or by subscription.

Most builds move through four stages, and skipping one is the usual reason a program stalls.

Governance sits with a steering committee drawn from the parent business. The center itself runs on hard measures: cost per invoice, days-to-close, first-contact resolution and customer satisfaction scores.

Headcount economics hold up too. Per the Bureau of Labor Statistics, business and financial operations roles, which make up the bulk of SSC staffing, are projected to grow 7% through 2033.

Location strategy matters as much as design. A captive center in the Philippines, India, Poland or Costa Rica delivers labor arbitrage of 50–70% against US or UK rates, while keeping staff on the parent’s payroll.

Attrition is the quiet risk. Offshore finance and helpdesk roles turn over faster than their onshore equivalents, so mature centers budget for a training bench, clear career ladders and documented processes instead of assuming the first cohort stays put.

Funding models decide behavior. A flat corporate allocation invites business units to over-consume, while per-transaction chargeback makes them curious about their own volumes — and that curiosity drives the second wave of savings.

Examples

Real programs look nothing like the textbook diagram. The four below span consumer goods, energy and an entire national sector, and each one shows a different reason companies keep this work in-house.

• Procter & Gamble Global Business Services: runs finance, HR, IT and facilities for the whole group from hubs in Manila, San José and Newcastle. The center serves roughly 100,000 employees, and Gartner has repeatedly cited it as a benchmark global business services program.
• Shell Business Operations: five sites, in Manila, Krakow, Chennai, Bengaluru and Kuala Lumpur, cover finance, HR, contracting and customer operations for Shell’s upstream and downstream units. The Manila site alone employed more than 5,000 people as of 2024.
• Unilever Enterprise & Technology Solutions: consolidated 26 separate finance back offices into four global hubs between 2018 and 2023, and reported days-to-close falling from eight days to three across the group.
• The Philippine IT-BPM sector: the IT and Business Process Association of the Philippines reported USD 38 billion in revenue and 1.82 million direct jobs in 2024, with captive centers taking a growing share of new hires.

Notice what these programs share. Each standardized before it automated — and each reports to a steering committee with real budget authority, rather than to a single function chasing its own numbers.

Each also sequenced the work. Transactional volume moved first, judgment work followed only once the base was stable, and analytics arrived last. Reverse that order and the center inherits chaos it cannot price.

FAQ

The five questions below cover what buyers ask most often about shared services: how it differs from outsourcing, which functions move first, what the model saves, where the centers sit, and whether automation has changed the answer.

How is shared services different from outsourcing?

Shared services keeps the team inside the parent company, on its payroll and inside its security perimeter. Outsourcing hands the same work to an external vendor under a contract. Many large groups run both at once.

What functions are usually first into a shared services center?

Finance and accounting almost always go first: accounts payable, accounts receivable, general ledger and payroll. HR transactional work and the IT helpdesk form the typical second wave.

How much does a shared services model actually save?

Mature centers report 25–40% lower process costs once standardization and automation are in place. Offshore labor arbitrage adds another 50–70% on the affected roles.

Where are most shared services centers based?

The Philippines, India, Poland, Malaysia, Costa Rica and Romania dominate the list. Manila is the largest single hub for English-language finance and customer operations work.

Is shared services still relevant with automation and AI?

Yes, because automation moves the work rather than the model, so your people handle exceptions and analytics while software clears the volume.
