Objectives: In highly competitive business-to-business (B2B) markets, customer loyalty has become a strategic necessity due to digital transformation, intensifying competition, and rising customer acquisition costs. Prior research has identified isolated drivers of B2B loyalty, such as trust, satisfaction, and relationship quality but has treated them as static, stage-specific outcomes rather than as elements of a connected journey; consequently, existing frameworks suffer from a “journey blindness,” failing to explain how operational drivers at one funnel stage translate into psychological mediators and financial outcomes at later stages. This study addresses this gap by developing an evidence-based, cross-stage framework that, unlike prior single-stage models, explicitly links funnel transitions to loyalty formation, and distinguishes genuine relational loyalty from loyalty driven merely by switching costs or contractual lock-in.
Methods: This study employed a qualitative meta-synthesis approach, following the seven-step Cochrane protocol and reported per PRISMA guidelines. A systematic search of six international databases (ScienceDirect, Springer, Wiley, Sage, Emerald, Taylor & Francis) and four Persian databases (Noormags, SID, MagIran, ensani.ir) covering 2000–2026 yielded 580 records; after removing 102 duplicates and screening by title (n = 268 retained), abstract (n = 107 retained), and full text, 49 studies met the inclusion criteria and formed the analytical core. Study quality was assessed with the CASP checklist (threshold ≥ 25/50; mean = 38.9, range 31–48). Data were extracted through a three-level coding process (open, axial, selective), and inter-coder reliability was confirmed on 20% of the sample (Cohen’s κ = 0.79).
Findings: The central contribution of this synthesis is the identification of inter-stage transition mechanisms, rather than isolated stage-level drivers—as the primary explanatory force behind cumulative loyalty formation; loyalty foundations laid in early stages (e.g., organizational image, digital content marketing) systematically determine the strength of later relational and financial outcomes, a linkage absent from prior single-stage models (Purmonen et al., 2023; Wirtz et al., 2025). Furthermore, the framework distinguishes “genuine loyalty,” rooted in value co-creation and emotional attachment, from “constrained loyalty” driven by switching costs or contractual governance, showing that only the former reliably converts into sustainable financial outcomes such as customer lifetime value. The meta-synthesis results led to the development of a multi-level, process-oriented framework conceptualizing B2B customer loyalty as a dynamic and cumulative phenomenon across six main stages of the marketing funnel: awareness, interest and consideration, evaluation and preference, purchase and experience, retention, and commitment and loyalty. The findings indicate that each stage has distinct yet interconnected drivers and mechanisms. In the early stages, organizational image, brand reputation, inbound digital marketing, search engine visibility, and corporate social responsibility play a key role in need recognition and initial engagement. In the interest and evaluation stages, customer knowledge management, educational content, specialized sales competence, solution customization, and trial periods serve as main drivers shaping perceived value and risk–benefit assessment. At the purchase and experience stage, service process efficiency, digital platforms, multichannel integration, and transactional accuracy are decisive for value realization and experience formation. In the retention and commitment stages, relational investments, proactive conflict management, coordination between buying and usage centers, and value co-creation play a central role in strengthening emotional attachment, relationship stability, and long-term commitment. The framework also identifies four categories of loyalty outcomes: (1) attitudinal (e.g., emotional commitment, brand identification, resistance to competitors), (2) behavioral (e.g., repeat purchase, contract renewal, wallet share growth), (3) advocacy (e.g., professional referrals, positive word-of-mouth, information sharing), and (4) economic (e.g., customer lifetime value, sales return, profitability, reduced acquisition and coordination costs). Additionally, the moderating role of contextual and intervening conditions including competitive intensity, technological turbulence, regulatory environments, cultural factors, relationship length, switching costs, governance mechanisms, and internal organizational silos was highlighted.
Conclusion: Unlike prior frameworks that model B2B loyalty as a set of stage-bound outcomes, this study’s principal theoretical contribution is the concept of the “B2B loyalty journey,” which reframes loyalty as the cumulative product of successful inter-stage transitions rather than a terminal post-purchase state. The findings indicate that B2B customer loyalty is more accurately understood as a longitudinal, stage-based journey rather than merely a post-purchase outcome. The proposed framework integrates fragmented research streams, addresses the “blind spots” of the customer journey, and provides a comprehensive picture of how loyalty is formed, accumulated, and transformed into strategic and financial value. The model contributes theoretically by linking funnel processes, psychological and relational mechanisms, and multidimensional loyalty outcomes to the existing literature. From a managerial perspective, the framework serves as a diagnostic and strategic tool for prioritizing touchpoints, allocating resources, and aligning digital, relational, and experiential investments to strengthen sustainable loyalty and customer lifetime value.
