65 Customer Relationship Marketing
65.1 What is Customer Relationship Marketing?
Customer Relationship Marketing (CRM) is the strategic approach of building, maintaining, and enhancing long-term, mutually rewarding relationships with customers through personalised, data-driven engagement. It is the antithesis of transactional marketing — the focus shifts from single transactions to enduring relationships.
Christian Grönroos defines relationship marketing as “the process of identifying and establishing, maintaining, enhancing and, when necessary, terminating relationships with customers and other stakeholders, at a profit, so that the objectives of all parties involved are met” (gronroos1994?). Leonard Berry — who introduced the term in 1983 — defined it as “attracting, maintaining and enhancing customer relationships” (berry1983?).
TipThree Working Definitions
| Author | Definition | What it foregrounds |
|---|---|---|
| Leonard Berry (1983) | “Attracting, maintaining and enhancing customer relationships.” | Three-stage focus |
| Christian Grönroos | “The process of identifying, establishing, maintaining, enhancing and terminating relationships with customers and stakeholders at a profit.” | Whole life-cycle |
| Kotler & Keller | “The process of cultivating the right relationships with the right constituents — customers, employees, marketing partners, members of the financial community.” | Stakeholders |
65.1.1 Transactional vs Relationship Marketing
TipTransactional vs Relationship Marketing
| Feature | Transactional | Relationship |
|---|---|---|
| Time horizon | Short — single sale | Long — series of interactions |
| Focus | Product features | Customer benefits |
| Customer contact | Limited | Frequent |
| Quality concern | Production quality | Total experience |
| Loyalty | Repeat purchase | Active advocacy |
| Customer service | Minor | Central |
65.2 Customer Lifetime Value (CLV)
The single most important metric in CRM. CLV is the present value of all future profits generated from a customer over the duration of the relationship.
\[\text{CLV} = \sum_{t=1}^{n} \frac{(R_t - C_t)}{(1+r)^t} - \text{Acquisition cost}\]
A simpler perpetuity form when margins and retention are stable:
\[\text{CLV} = \frac{\text{Margin} \times \text{Retention rate}}{1 + \text{Discount rate} - \text{Retention rate}}\]
The retention rate is the proportion of customers who stay year-on-year. Customer Equity is the aggregate of CLVs across the customer base — the firm’s most important long-run asset (Kotler).
65.3 CRM Process
TipFive Stages of the CRM Process
| # | Stage | What happens |
|---|---|---|
| 1 | Customer identification | Build a customer database; segment |
| 2 | Customer differentiation | By value (CLV) and needs |
| 3 | Customer interaction | Personalise touchpoints |
| 4 | Customisation | Tailor offerings, prices, messages |
| 5 | Performance evaluation | Measure CLV, retention, NPS, advocacy |
65.4 Three Forms of CRM
TipThree Forms of CRM
| Form | What it does |
|---|---|
| Operational CRM | Sales, marketing and service automation |
| Analytical CRM | Customer-data analysis, propensity modelling, segmentation |
| Collaborative CRM | Sharing customer information across functions and channels |
65.5 The Loyalty Ladder
Payne, Christopher and others describe a customer loyalty ladder with progressively deeper relationships:
TipThe Customer Loyalty Ladder
| Stage | Description |
|---|---|
| Prospect | A potential customer |
| Customer | First-time buyer |
| Client | Repeat purchaser |
| Supporter | Likes the brand; will recommend |
| Advocate | Actively promotes the brand |
| Partner | Co-creates with the brand |
65.6 Customer Retention
Empirical research consistently finds that retaining a customer is 5 to 25 times cheaper than acquiring a new one. Retention is the foundation of CLV.
65.6.1 The 80/20 Rule
The Pareto principle in CRM: roughly 80 per cent of profit comes from 20 per cent of customers. The corollary — segment customers by CLV and treat them differently.
65.6.2 Customer Loyalty Programmes
TipCommon Loyalty Programme Designs
| Type | Mechanic | Example |
|---|---|---|
| Points-based | Earn and burn | Airline frequent-flier |
| Tiered | Status levels with escalating benefits | Amex Platinum / Centurion |
| Paid membership | Recurring fee | Amazon Prime |
| Cash-back | % returned to customer | Credit-card rewards |
| Coalition | Multiple partners | PayBack |
65.7 Customer Experience Management (CXM)
Modern CRM has expanded into Customer Experience Management — the active orchestration of every customer interaction with the brand to deliver a coherent, valuable experience. The customer journey map is the central tool — covering awareness → consideration → purchase → onboarding → use → service → renewal / advocacy.
Three modern CXM concepts:

| Concept | What it captures |
|---|---|
| Moments of truth | Critical interactions where customer perception is shaped (Jan Carlzon, SAS) |
| Customer effort score (CES) | How easy was it to get the issue resolved? (Dixon et al.) |
| Total customer experience (TCX) | The sum of all interactions across the journey |
65.8 CRM Technology Landscape
Modern CRM rests on technology. Major categories:
