Instead of demanding a large budget upfront, CMOs should partner with the CFO on a pragmatic, step-by-step journey. At e.l.f. Cosmetics, the marketing budget grew from 6% to 24% of net revenue over six years by proving the ROI of each incremental increase, building a strong case for continued investment over time.

The key to justifying brand marketing isn't a perfect dashboard, but internal education. A marketing leader's primary job is to explain to the CFO and sales team that buying decisions are not linear and are influenced by multiple, often unmeasurable touchpoints over time.

To avoid constant battles over unproven ideas, proactively allocate 5-10% of the marketing budget to a line item officially called "Marketing Experiments." Frame it to the CFO as a necessary fund for exploring new channels before current ones tap out and for seizing unforeseen opportunities.

To shift from performance to brand marketing, SAS's CMO built a strategic alliance with the CFO. This involved mutual literacy training (marketing for finance, finance for marketing) and embedding a finance business partner directly into the marketing leadership team, turning finance into a powerful advocate.

CFOs are often skeptical, viewing loyalty as a cost center for customers who would buy anyway. To overcome this, brands must move beyond vanity metrics and use attribution models that directly tie every loyalty campaign and strategy to incremental revenue on the P&L statement.

MasterCard's CMO advises embedding a finance professional on the marketing team who can present ROI data to leadership. Because the message comes from a non-marketer, it carries more weight and credibility with the CFO and board. This tactic acknowledges that who delivers the message is as important as the message itself.

To gain the CFO's confidence, GM's marketing head involved the CFO's team in the steering committee for developing the marketing plan. This transparency and disciplined approach built a strong partnership and prevented budget cuts driven by misunderstanding.

To justify creative budgets to a CFO, translate creative quality into hard metrics. Strong creative increases demand (lowering CAC), boosts retention (increasing LTV), and reduces the risk of costly cultural backlash (cost avoidance), positioning creativity as a core business growth driver.

Position marketing as the engine for future quarters' growth, while sales focuses on closing current-quarter deals. This reframes marketing's long-term investments (like brand building) as essential for sustainable revenue, justifying budgets that don't show immediate, direct ROI to a CFO.
