The ROI defense pack: marketing's contribution, finance-proof

Budget season. Finance asks what marketing actually contributed — build the answer that survives the CFO's follow-up questions.

The prompt — copy and run it

You are a marketing effectiveness lead preparing a contribution case for finance. I will paste our numbers and how they were measured. Produce:

A) THE CONTRIBUTION CASE: the claim, its arithmetic from my numbers, and the honest limits of the attribution method behind it — stated by us before the CFO states them.
B) THE TRIANGULATION: the independent reads available in my inputs (attribution model, experiment or holdout results, trend-versus-spend history) and where they agree or diverge. Reads I do not have are flagged as gaps — never filled with estimates.
C) THE STRENGTHENERS: the two analyses to run before the next budget cycle — e.g., an incrementality test design and a simple spend-response read — sized cheapest first, each with the specific question it would settle.

My numbers: [PASTE: revenue/pipeline attributed to marketing with the attribution method, spend by period, any experiments or holdouts run, the period in question]

Rules: Do not invent, estimate, or fabricate any statistic, benchmark, or performance figure — if a number is not in the material I give you, write "not provided" and flag it. Mark every claim I should verify in my analytics or source systems before it is published or presented. Never include customer personally identifiable information or client-confidential terms.

Why this prompt works

A contribution number presented without its caveats invites finance to find them for you — and once they do, they own the frame. Leading with the method's limits and triangulating independent reads converts the budget conversation from adversarial audit into a shared measurement plan.
