Loyalty is a proven growth engine for the business. Yet, SAP’s latest B2B Buyer Loyalty Index 2025 reveals a striking paradox:

• 86% of B2B buyers allocate more budget when suppliers act as strategic partners.
• However, only 35% of organizations have reached “strategic loyalty”—the level where relationships deliver measurable, enduring impact.

This gap represents a massive opportunity to grow revenue from existing customers and gain new customers through satisfied customer referrals. Yet, most organizations still treat loyalty as a marketing tactic rather than an enterprise-wide business strategy.

The six types of B2B buyer loyalty

The SAP B2B Buyer Loyalty Index (BLI) builds on the foundation of the Customer Loyalty Index (CLI), which launched five years ago. Together, these global reports provide a clear, actionable framework for understanding and driving loyalty across both consumer and business buying journeys.

In 2025, we uncovered six distinct types of loyalty shaping how B2B buyers engage and commit to their suppliers:

• Strategic Loyalty: Long-term commitment based on trust, shared goals, and mutual value.
• Incentivized Loyalty: Loyalty that is developed through pricing advantages, rebates, or bundled services.
• Legacy Loyalty: Loyalty based on historical relationships, long-standing contacts, or institutional memory.
• Default Loyalty: Loyalty due to lack of alternatives or integration complexity.
• Value-based Loyalty: Loyalty based on vendors aligned with ESG goals or corporate ethics.
• Adaptive Loyalty: Loyalty around cutting-edge solutions or vendors with market buzz.

Why strategic loyalty matters

Today’s B2B buyers behave more like consumers: they expect relevance, trust, and value at every touchpoint. Loyalty is no longer built solely on rebates or quid pro quo transactional relationships. Instead, organizations earn buyer loyalty through shared goals, seamless experiences, and proactive engagement that honors the mutual investment customers and brands make in one another.

The stakes are high:

• 95% of buyers say a supplier’s use of AI positively impacts loyalty
• 28% cite disconnected experiences as a loyalty breaker
• Buyers switch quickly when service, cost, or values are misaligned

In short, loyalty is fragile and fleeting. To thrive, brands must engineer loyalty rather than leave it to chance.

The cost of inaction

Failing to close the loyalty gap means:

• Higher churn
• Higher customer acquisition costs
• Lost opportunities for upsell and cross-sell
• Vulnerability to competitors who prioritize strategic partnerships

When loyalty isn’t operationalized, even long-standing relationships can erode. 67% of buyers have switched suppliers due to a lack of innovation. That’s a wake-up call.

Three proven strategies to move forward

SAP’s B2B buyer loyalty research points to three essentials for 2026. The most successful organizations will review these as foundational shifts.

1. Unify CX Engagement Signals: Break down silos between marketing, commerce, and service. Connect data into one event-driven engagement layer, so every interaction reflects real-time context.

Why it matters: Buyers expect consistency across channels. Disjointed experiences are a top loyalty threat.

2. Standardize KPIs Beyond Clicks: Move beyond surface metrics like impressions and clicks. Measure loyalty outcomes such as:

• Repeat purchase rates
• Time-to-resolution
• Contribution margin
• Lifetime value vs. cost of customer acquisition

Why it matters: Loyalty must tie back to revenue and margin.

3. Operationalize Personalization: Equip CX teams with shared profiles and AI-driven insights. Ensure every touchpoint across email, app, web, and service feels connected and relevant.

Why it matters: Personalization is an expectation across B2C and B2B buyers. 24% of B2B buyers are more loyal to suppliers who personalize marketing.  This moves beyond [%name% here] to offers that are highly relevant, timely, and reflect the purchase history, needs, and interests uncovered by connected data and powered by predictive AI.

From insight to action

The loyalty paradox creates a strategic imperative for many organizations. This is an opportunity to evolve loyalty from a siloed initiative to an enterprise-wide growth strategy. That means:

• Treating loyalty as a shared goal across Marketing, Sales, Service, and Procurement.
• Using AI to predict and respond to loyalty, demand, and satisfaction signals in real time.
• Connecting data and processes to deliver trust and value at scale.

Loyalty drivers like personalized service, relevant product recommendations, and proactive support require connected CX data and real-time engagement orchestration. When customers feel understood and valued, they choose you over and over. The organizations that act now will turn loyalty into a predictable growth engine. Those that don’t? They’ll keep wondering why their best customers keep walking away.
