Build high-confidence cases that connect marketing to business value.

It supports investment decisions by demonstrating how a proposed initiative creates measurable business outcomes. For senior marketers, it is the foundation for securing resources, aligning stakeholders, and turning intent into action.

Why Business Cases Matter in B2B
Even the best ideas fail without internal alignment. A business case positions Marketing as a strategic partner—one that speaks the language of Finance and Executive Management. It reduces friction, raises credibility, and enables better, faster decisions.
Use a business case when:
Proposing budget for major campaigns or launches
Entering new markets or segments
Shifting strategy, pricing, or positioning
Investing in platforms, tools, or talent
Seeking cross-functional support or shared ownership
Best Practices for Building a Marketing Business Case
Start with the business priority. Link the marketing initiative to a top-line or margin-relevant outcome, not just a tactical metric.
Use hard data to justify assumptions. Draw from customer behavior, funnel performance, or pilot results—never speculation.
Balance numeric ROI with qualitative gains. Show both financial returns and strategic upside, such as positioning, retention, or scalability.
Clarify the trade-offs. Be upfront about what resources are needed and when value will materialize.
Pre-align with decision-makers. Circulate early drafts and refine based on feedback—build agreement before you ask for a decision.
Five-Step Development Framework
1. Define the strategic objective.
Clarify what the initiative aims to achieve and how it aligns with current business goals. Define the boundaries of scope, ownership, and timeline.
2. Gather evidence and requirements.
Collect relevant market data, internal benchmarks, resource needs, and customer insights. Document critical dependencies or uncertainties.
3. Build financial logic.
Estimate required investment. Model potential return—revenue, cost savings, customer lifetime value. Provide conservative, expected, and optimistic cases.
4. Write the narrative.
Summarize the problem, your proposed solution, and its impact. Make the story executive-readable in under 400 words. Leave supporting details for appendices or discussion.
5. Align and finalize.
Share with key stakeholders for input. Address their concerns and refine the case. Once approved, integrate it into planning, execution, and performance reviews.
What Often Goes Wrong
Assuming “the idea will sell itself.”
In B2B, decision-makers expect evidence and business logic—not enthusiasm.
Avoiding numbers because “marketing is hard to quantify.”
Use directional estimates based on conversion rates, funnel data, or analog campaigns.
Treating the case as static.
Update the business case as inputs change—new data, shifting priorities, unexpected barriers. It should evolve with the initiative.
Real-World Scenarios
A European SaaS vendor used a business case to shift budget from events to account-based marketing. By modeling cost per lead, conversion rates, and pilot results, the team unlocked new budget lines and executive support.
A global component manufacturer created a business case for launching a new product family in Asia. By tying market demand, internal capacity, and phased financial planning into one narrative, they accelerated board approval and regional buy-in.
Moving Forward
A business case is not a slide deck—it’s an internal strategy asset. It gives structure to complex decisions and positions marketing as a builder of enterprise value.
Start small. Draft a one-page summary for your next strategic idea. Ask yourself: if Finance or the CEO read this today, would they say yes?
