STRATEGIC CLIENT RELATIONSHIP MANAGEMENT IN THE B2B TELECOMMUNICATIONS SECTOR: A FRAMEWORK FOR SUSTAINABLE CORPORATE PARTNERSHIPS

This article examines the critical success factors in Business-to-Business (B2B) client relationship management within the telecommunications industry, drawing on empirical observations from large-scale multinational operations. The analysis draws on four years of professional practice (2018–2022) managing corporate client portfolios in telecommunications, supplemented by systematic observation of organizational practices, performance metrics analysis, and evaluation of client satisfaction indicators. Analysis of corporate portfolio management practice yields four interconnected strategic pillars that distinguish high-performing B2B relationships from transactional service arrangements. The four-pillar framework presented — customized solution architecture, proactive relationship management, SLA excellence, and strategic contract management — provides a practical guide for telecommunications organizations seeking to strengthen corporate client retention and satisfaction. The findings reflect a broader pattern in the evolution of business administration, demonstrating that disciplines once considered purely operational are increasingly recognized as sources of strategic value.
