What Sterling Outsourcing does

Sterling Outsourcing Sp zoo is a privately held business process outsourcing (BPO) provider founded in 2007 in Kraków, Poland, delivering credit management, debt recovery, finance & accounting, multilingual customer experience, and HireChecker backdoor-hire detection services. Headquartered at Kurniki 9 in Kraków, the company operates additional delivery hubs in Łódź (Poland, opened September 2024) and Mumbai (India, opened January 2025), with sales presence across the UK, EU, US, and Australia. Under CEO Harry Virdee, who succeeded founder Jeremy Milligan in 2024, Sterling rebranded from 'Sterling Outsourcing' to simply 'Sterling' in February 2025. The company employs more than 2,000 professionals from over 30 nationalities, supports 33+ languages, and serves over 1,500 clients across recruitment, finance & accounting, financial services, technology, healthcare, logistics, ecommerce, and insolvency sectors.

Sterling's product portfolio combines human-agent delivery with proprietary technology, anchored by the HireChecker automated deep-web search system for recruitment-sector disputes, real-time reporting dashboards, and invoicing/CRM integrations that allow clients to monitor operations as they happen. Core service lines include Credit Control (with sub-metrics for DSO, Collection Effectiveness Index, and AR Turnover), Customer Experience (24/7/365 omnichannel CX handling 35 million+ interactions annually), Debt Recovery (commission-only with fixed-fee and hourly options for insolvency practitioners, including in-house legal escalation), and ACCA-led Finance & Accounting. Reported operational outcomes include 30% DSO reductions, 25-45% reductions in outstanding receivables for enterprise clients, 90% CSAT, and 99%+ client retention, with 0% attrition cited under the new leadership.

The business model is a mix of commission-based debt recovery (transaction-fee revenue), managed BPO services for CX, credit control, and finance & accounting on bespoke multi-year contracts, and professional services for HireChecker. Sterling sells exclusively B2B via direct enterprise sales, inside sales to mid-market/SMB, and a referral channel (e.g., a top-50 UK accountancy firm regularly recommending Sterling to its own clients). Pricing is quote-based and not publicly disclosed. The company maintains stated compliance with ISO 27001, ISO 9001, SOC 2, PCI-DSS, and GDPR-focused practices, and has won multiple regional industry awards in 2025-2026 including Best Customer Experience Provider in Central & Eastern Europe.
