Agencies
The report clients actually read: a one-page structure
Nobody opens a 40-slide report. The one-page structure that answers what the client wants to know, and what to cut without losing anything that matters.
Also available in: Português · Español
The 40-slide report an agency builds on the first Monday of every month, which the client opens at slide 1 and closes, is one of the industry's biggest wastes of time. Not because the client is uninterested — because the document does not answer what they want to know.
They want to know four things. Only four.
The four questions
1. What did we spend? The number that left their account.
2. What came back? In leads, in sales and in revenue — not in impressions.
3. What did we learn? One thing you know today that you did not know last month.
4. What comes next? Two or three actions, with an owner and a date.
Everything else is an appendix. Literally: make it available, off the path.
The one-page structure
OCTOBER 2026 · ACME
RESULTS
Spend $42,000 (Sep: $38,000)
Leads 312 (Sep: 341)
Sales 28 (Sep: 21)
Revenue $196,000 (Sep: $147,000)
Return 4.7x (Sep: 3.9x)
Leads fell 8%, sales rose 33%. We cut volume on purpose
and quality more than made up for it.
WHAT WORKED
· Creative "Ana testimonial": 11 of 28 sales, CAC $980
· Remarketing campaign: 2.1x the return of prospecting
· The 35-50 audience closed better than 25-34 for the first time
WHAT DID NOT
· Brand campaign: $6,400, 1 sale. Paused on the 18th.
· Carousel format did not deliver this month
WHAT WE LEARNED
A lead from the price creative closes at 6%; from the
testimonial creative, at 19%. The second costs 30% more
and is worth twice as much.

It fits on a phone screen. It reads in two minutes. And it contains everything the meeting will be about.
What to cut, and why
Impressions, reach, CPM, CTR, frequency. Diagnostic metrics, yours. The client decides nothing with them. They enter the body only when they explain a change in results: "CPM rose 40% during Black Friday, which is why CPL rose".
Screenshots of the ads manager. They show that you opened the tool, not that you understood anything.
A 30-day line chart with daily noise. Noise, drawn. If the trend matters, say it in a sentence.
Comparison only with the previous month. One month against the last hides seasonality. Compare also with the same month last year, or with the three-month average.
The three rules that change the relationship
Revenue, not conversions
"312 conversions" is platform information. "28 sales, $196,000" is business information. As long as the report speaks in conversions, the conversation will be about your tool. When it speaks in revenue, it becomes a conversation about the business — and then you are on the same side of the table.
That requires the CRM connected. Without it, you are condemned to report what the platform thinks happened.
The bad month goes at the top
The temptation is to bury the bad number in the middle. It does not work: the client finds it, and the cost of them finding it alone is trust.
Bad news at the top, with cause and plan:
Sales fell from 34 to 21. Two reasons: the creative carrying 40% of volume saturated (frequency passed 4.2) and we had 9 days with a broken form, fixed on the 14th. Three new creatives go live this week.
That is bad news that produces a productive conversation. The same number hidden on page 7 produces a conversation about why you hid it.
The CRM gap gets explained, not hidden
If the platform says 312 conversions and the client's CRM shows 280 leads, say so. Attribution window, duplicate leads, a form that failed, a conversion counted in more than one campaign — there are real, known reasons.
Explaining once costs a paragraph. Getting caught on the gap in a meeting costs the contract.
The appendix exists, and it matters
Nothing you cut disappears. It sits behind a link: breakdown by campaign, by ad set, by creative, daily series, all of it.
The difference is that the detail is available, not imposed. The client who wants to check, checks. The one who does not, reads the page and goes back to work. Both leave satisfied, and neither loses half an hour.
The right frequency
Monthly for the document. Weekly for the heads-up, in three lines over email or chat: what changed, what is about to change, whether anything is needed.
The weekly note is what keeps the monthly report from being a surprise. A client who follows along closely does not get a shock at month end — and a client who does not get a shock renews.
For the in-house routine that feeds these numbers, see a weekly optimization routine. For the return calculation in the first section, see true cost per sale.
Frequently asked questions
How long should a monthly report be?
One page answering four questions: what we spent, what came back, what we learned and what comes next. Detailed appendices stay available for anyone who wants them, but off the main path.
Should I show metrics like CTR and CPM?
Not in the body. Those are diagnostic metrics, useful to you. They belong in the report only when they explain a change in results — and then as a cause, not as a table row.
How do I report a bad month?
Openly and at the top. Then the likely cause and what has already been done. A client who discovers it alone loses trust; a client who is told evaluates the plan.
Should I show data that does not match the client's CRM?
Yes, and explain why. Hiding the gap guarantees it surfaces at the worst possible moment, in a meeting, with you unprepared.
