The attribution report a CFO will subscribe to
Nobody in finance is going to log into your attribution tool. The report that gets read is the one that arrives, fits on a page, and says how sure it is.

The attribution report that finance actually reads is a page that arrives on a schedule, states a number with a range, and names the method that produced it. A dashboard invitation is not a report, it is homework.
Marketing teams underestimate how much of the credibility problem is format. The same estimate, delivered as a dashboard link, reads as a claim you would like finance to accept. Delivered as a short recurring document with its uncertainty on the face of it, it reads as work.
What belongs on the page
| Element | Why finance cares |
|---|---|
| One number per channel | It maps to a budget line |
| The range around it | It tells them how much to trust the line |
| Coverage | It says what share of real orders the read explains |
| Method, one sentence | It lets them rank this against other evidence |
| What changed since last time | It is the only part they will read first |
The last row is the one marketers leave out and finance opens with. A recurring report is read as a diff. If nothing material moved, say so in a line, and the report earns trust rather than spending it.
Why the range increases credibility
There is a persistent instinct to strip uncertainty out before sending, on the theory that a confident number persuades better. In a budget conversation the opposite holds. A number with a range says the person who produced it knows what the method can and cannot resolve, which is exactly the competence finance is checking for.
It also protects you. When a channel with a wide interval underperforms next quarter, a report that showed the width was honest in advance. A report that showed a single confident figure was wrong in public. We set out the mechanics in a defensible attribution report you can export and the meeting itself in how to prove marketing incrementality in budget meetings.
The three questions to pre-answer
Finance asks the same three questions, so answer them on the page before they are asked. First, how does this differ from what the ad platforms report, which is usually a large gap and is covered in platform attribution overcounting. Second, what would change your mind. Third, what is not measured, and why.
The third one is where most reports quietly fail. Channels below the spend level at which any method can separate their effect belong in a named "not measurable at this spend" row, not in the main table with a plausible-looking figure beside them.
Cadence beats depth
Monthly is usually right. Weekly invites over-reading of normal movement; quarterly is too slow to change a decision. Whatever you pick, keep it, because the value of a recurring report is that the reader learns its shape and can spot the week it looks different.
Automating the assembly is what makes a fixed cadence survive a busy month. The €99 one-time read produces the same output shape as a manual upload if you want to see whether the page is worth building first.
One thing to stop doing
Stop sending the dashboard link with "let me know if you have questions". It transfers the work of interpretation to the person least equipped to do it, and it reads as a lack of a view. Send the page. Have the view. Show the range.

Frequently asked questions
What should a monthly marketing attribution report include for finance?
One estimate per channel, one sentence naming the method, and a short note on what changed since the previous report. Anything longer competes with the reader's attention rather than earning it.Should I show confidence intervals to my CFO?
Yes. A range signals that you understand the limits of the method, which is the competence finance is assessing. It also protects the report's credibility when a channel with a wide interval behaves unpredictably, because the width was disclosed in advance.How often should attribution be reported to stakeholders?
Monthly suits most DTC brands. Weekly encourages over-interpretation of normal variation in a causal estimate, and quarterly arrives too late to influence the budget decisions it is supposed to inform. Consistency of cadence matters more than the specific interval.
