Sterling’s Client-Centered Approach to Outsourcing Services

Sterling, founded in 2007 in Kraków, Poland, has built its business by providing multilingual customer support, financial back-office processes, credit control, debt recovery, and order-to-cash services for over 1500 clients worldwide. The company works across sectors including recruitment, financial services, healthcare, telecom, insurance, and government.

According to data from Grand View Research, the global business process outsourcing (BPO) market was valued at $302.6 billion in 2024 and is projected to reach $525.2 billion by 2030, reflecting an expected compound annual growth rate of 9.8%. Sterling operates within this expanding market while focusing on highly specialized financial and customer management processes.

While competing with larger outsourcing firms, Sterling has concentrated on services that integrate closely with client systems and workflows. Its delivery hubs in Europe and Asia enable operations across global markets.

Tailored Solutions for Complex Requirements

One of Sterling’s defining strategies has been developing customized frameworks for managing multilingual customer service and financial processes. Rather than deploying uniform models across industries, the company adapts processes to fit the operational structures and regulatory requirements of each client.

This approach has been especially significant in credit control and debt recovery. Sterling manages tens of millions of pounds in debts annually, often for cross-border disputes. In one case, the company successfully recovered several hundred thousand euros that had been classified as uncollectible for four years. By negotiating repayment plans, accommodating religious and cultural sensitivities, and maintaining transparent communication, Sterling resolved the case without litigation, demonstrating the need for flexibility in international debt recovery.

“Businesses today expect transparency and measurable results,” said Harry Virdee, Sterling’s CEO. “Our goal is to integrate seamlessly with client operations while making sure the data they rely on is accurate, timely, and actionable.”

Multilingual Capabilities and Workforce Diversity

With over 30 nationalities on board, Sterling has positioned cultural fluency as a central operational strength. Its multilingual hubs in Europe and Asia handle multilingual customer interactions supporting clients across the globe.

This diversity has enabled Sterling to manage complex customer service environments, particularly for multinational clients with region-specific compliance and communication needs. For sectors such as healthcare and financial services, regulatory obligations differ sharply across countries, requiring culturally sensitive customer engagement strategies.

According to a 2025 study by Deloitte, 71% of businesses working with outsourced service providers cite multilingual capability as a key factor in vendor selection. Sterling’s ability to match regional language requirements with financial and customer service processes has become an operational differentiator within competitive markets.

Adapting to Market Growth and Expansion

Sterling’s expansion into Asia-Pacific and the Middle East reflects broader trends in outsourcing demand. Industry forecasts estimate that Asia-Pacific will see a 12% CAGR through 2030, fueled by increased adoption of customer experience outsourcing and financial back-office integration.

The company’s Indian delivery centre, grew in response to answering client needs, provides extended time-zone coverage and access to highly skilled talent pools. Additionally, Sterling has strengthened its footprint in Europe by replacing six competing vendors, including several tier-one outsourcers, for multilingual customer support contracts in Poland, Portugal, and Bulgaria.

“The outsourcing market is becoming more complex,” Harry Virdee noted. “Clients want scale, but they also expect accountability and visibility across all processes. That’s where the industry is headed, and we’ve aligned our operations to reflect that shift.”

Positioning for the Next Decade

With the outsourcing industry undergoing significant transformation through automation, artificial intelligence, and regulatory compliance demands, Sterling has focused on aligning its services with emerging priorities. Beyond client operations, the company is actively investing in research and participating in industry forums to contribute to discussions about integrating automation and AI into multilingual customer experience. Sterling’s strategic direction suggests a shift toward thought leadership, where operational performance and market influence are treated as parallel objectives.
