One quarter, a marketing team celebrated twelve new customers worth $30,000 each. That same quarter, one existing $400,000 account quietly didn’t renew.
The new-logo number looked great on the slide. The business still went backward.
Scenarios like this are why more B2B leaders are moving budget toward install base marketing. This piece explains what’s driving the shift, the math behind it, and how to start without starving new growth.
What Install Base Marketing Actually Means
Install base marketing is marketing aimed at existing customers, with a clear revenue goal: keep them, grow them, and turn them into advocates.
It isn’t a customer newsletter. It also isn’t something customer success can carry alone. Instead, it applies the same discipline marketing uses for new business, including segmentation, targeting, campaigns, and measurement, to the accounts you already serve.
Three Forces Moving the Money
1. Budgets Aren’t Growing
Gartner’s 2025 CMO Spend Survey found marketing budgets flat at 7.7% of company revenue. Also, 59% of CMOs said they lacked the budget to execute their strategy.
When money stops growing, leaders look for the highest return on each dollar. That points toward existing customers.
2. New Customers Cost More to Win
As Harvard Business Review has reported, acquiring a new customer can cost five to 25 times more than keeping an existing one. The same article cites Bain & Company research showing that a 5% increase in retention can raise profits by 25% to 95%.
Those figures vary by industry. Still, the direction is hard to argue with.
3. Losing a Customer Is Hard to Replace
Research presented at Forrester’s B2B Summit put numbers on the cost of churn. According to one summary of the session, replacing one lost retention opportunity takes, on average:
| To replace one lost renewal, you need about | |
|---|---|
| Upsell opportunities | 6 |
| Cross-sell opportunities | 16 |
| New-logo opportunities | 30 |
Thirty new-logo opportunities to make up for one lost renewal. That ratio changes how any leadership team thinks about where effort goes.
Where New-Logo Thinking Still Dominates
Most marketing teams still run on acquisition habits, even when leadership says otherwise. You’ll usually see it in three places:
- Targets. Pipeline goals count only new business, so customer programs never make the plan.
- Metrics. MQL and new-logo counts get reported, while expansion pipeline doesn’t.
- Ownership. Renewals and growth sit entirely with customer success, which rarely has marketing’s reach or tools.
The result is a gap. Customers hear from marketing all the time before they sign, then almost never afterward.
Four Plays That Belong to Marketing
Install base marketing isn’t one campaign. It’s a set of plays, each with its own goal and metric.
| Play | Goal | Example | Metric |
|---|---|---|---|
| Adoption | Get customers using what they bought | Role-based campaigns for features customers haven’t adopted | Active usage by account |
| Expansion | Grow revenue inside each account | Cross-sell campaigns to departments not yet using you | Expansion pipeline |
| Renewal protection | Spot and reduce churn risk early | Value summaries sent before renewal talks start | Renewal rate |
| Advocacy | Turn happy customers into a growth channel | Case studies, reviews, and referral programs | Referral-sourced pipeline |
Many of these borrow directly from new-business marketing. For example, ABM tactics work well for expansion. You can also apply an account engagement score to customers, since falling engagement is often the first sign of risk.
The Renewal Risk Most Teams Miss
Renewals rarely fail on the day the contract ends. They fail months earlier, often in conversations the vendor never sees.
Two patterns stand out today:
- Tool consolidation. Security and IT leaders are cutting overlapping tools. As we covered in our piece on CISO buying decisions, vendors seen as point solutions are the first to go.
- Competitor research. Customers evaluate alternatives quietly. Intent data can show when an existing account starts researching your category, which is often a warning sign.
Marketing is well placed to catch both, because it already tracks engagement and research behavior at scale.
A 90-Day Starting Plan
You don’t need a new team to begin. You need a clear first quarter.
Days 1–30: Understand the base
- Segment customers by revenue, product use, and renewal date.
- Identify accounts using only part of what you sell.
- Agree with customer success on who owns which stage of the customer relationship.
Days 31–60: Launch two plays
- Pick one expansion play and one renewal protection play.
- Build content for specific roles, not generic “customer updates.”
- Set up post-sale nurture streams tied to usage and renewal timing.
Days 61–90: Measure and decide
- Track expansion pipeline and engagement changes in targeted accounts.
- Compare results with a similar group of untouched accounts.
- Decide what to scale in the next quarter.
A customer data platform helps once you scale. Early on, however, CRM data and product usage reports are usually enough.
How to Rebalance Without Starving Growth
None of this means stopping new-logo marketing. New customers still matter, and some markets demand them.
A practical approach is to move a small, fixed share of program budget, often 10% to 15%, into install base plays for two quarters. Then compare returns against new-logo programs using the same measure, such as pipeline or revenue per dollar spent.
That way, the data decides the next shift, not opinions.
What to Measure
Keep the scorecard short and tied to revenue:
- Net revenue retention: revenue kept and grown from existing customers
- Expansion pipeline: new opportunities inside current accounts
- Renewal rate: by segment and by product
- Product adoption: active use of purchased features
- Referral-sourced pipeline: new business that came through customers
The Cheapest Pipeline Is Already Under Contract
Your existing customers already trust you, already know your product, and already have budget with your name on it. Yet in many B2B companies, they get the least marketing attention of any group.
Install base marketing corrects that imbalance. It doesn’t replace growth from new logos. It protects and multiplies the growth you’ve already earned.

FAQs:
Install base marketing is marketing aimed at existing customers to improve adoption, expand revenue through cross-sell and upsell, protect renewals, and build advocacy.
Marketing budgets are flat, new customers cost more to win, and losing a customer is expensive to replace. Research presented at Forrester’s B2B Summit suggested that replacing one lost renewal takes around 30 new-logo opportunities.
Both. Customer success owns the relationship, while marketing brings segmentation, campaigns, and measurement at scale. The best results come when the two agree on shared goals and clear handoffs.
Net revenue retention, expansion pipeline, renewal rate, product adoption, and referral-sourced pipeline give the clearest view of impact.
There’s no single right number. A practical start is to move 10% to 15% of program budget into customer plays for two quarters, then compare returns against new-logo programs.
