# How to build a monthly marketing report as a marketer

There are three honest ways to build a monthly marketing report: manually (about half a day every month), with DIY AI prompting, or with a $19 ready-made agent. This guide compares all three with real pros and cons.

It turns your approved channel exports into the same report every month: campaign, spend, result, source, variance and the next question, with every number traced to its source row. Here are the three honest ways to get it done, with real trade-offs.

[Compare the 3 ways](#compare)[Skip to the ready-made agent](#way3) [Home](/) › [How-to guides](/how-to/) › Marketing Reporting

## Way 1: without AI (the manual way)

**Honest cost: half a day every month.**

1.  Download exports from every channel.
2.  Paste numbers into the report skeleton, checking each against its source.
3.  Re-answer "where did this number come from" for every figure.
4.  Rewrite the commentary from scratch.

Month-end reporting means downloading channel exports, pasting numbers into the same report skeleton and re-answering where-did-this-number-come-from every single time.

### Pros of doing it manually

  - Free except your time - no tools, no accounts.
  - You learn the job deeply and control every detail.
  - No data leaves your hands.

### Cons of doing it manually

  - half a day every month - every single time the job runs.
  - Quality depends on your energy that day.
  - More volume just means more hours; it does not scale.

## Way 2: with AI, but without AI Agent Skills (DIY prompting)

A chat assistant genuinely helps here. The catch is that you become the workflow designer. What you have to figure out yourself:

  - You must paste every export and last month’s format each month - nothing carries over.
  - You must force source citations per number or the report is unauditable.
  - You must keep the structure identical by hand, or months stop comparing.

Here is a starter prompt that works - copy it and bring the inputs listed:

    Prepare this month's campaign performance report from these approved exports: [paste]. One row per campaign: spend, result, source, variance vs plan, and one question this raises. Match last month's structure: [paste]. Every number must come from the export - if something is missing, mark it MISSING.

### Pros of DIY prompting

  - Free, or nearly - any chat assistant works.
  - A first draft in minutes instead of hours.
  - Fully flexible: tweak the prompt for any edge case.

### Cons of DIY prompting

  - You become the workflow designer: prompts, test data and output rules are yours to write, test and maintain.
  - Output drifts between sessions unless you re-paste the rules every run.
  - Nothing is saved for you - sheets, structure and context are rebuilt each time.

## Way 3: with AI Agent Skills ($19, one-time)

The [Performance Reporting Agent](/marketing/performance-reporting-agent/) is this job already designed: fixed evidence rules, output contract, test fixtures and stop points. You ask once:

> Hello, prepare this month’s campaign performance report

And a finished, review-ready artifact lands in your own Drive:

| Campaign                 | Spend  | Result                         | Source                    | Variance             | Next question     |
| ------------------------ | ------ | ------------------------------ | ------------------------- | -------------------- | ----------------- |
| Launch week LinkedIn ads | $1,850 | 34 demo bookings ($54/booking) | Ad platform export Sep 12 | 20% under target CPA | Scale budget 20%? |
| Webinar Sep 5            | $600   | 11 demos ($55/booking)         | Webinar platform + CRM    | On target            | Repeat monthly?   |

*Sample data shown. Your workspace fills with your real work.*

Setup takes about 10 minutes: buy, hand the three files to the assistant you already use (Instinct, ChatGPT, Claude, Gemini or any other assistant that reads files), approve the fictional-data test. Then it runs on a standing cycle or a one-line ask, and stops at every human gate. [Full method](/how-it-works/).

### Pros of the ready-made agent

  - About 10 minutes to a tested setup, not an afternoon of prompt tuning.
  - The same output shape every run - evidence rules and stop points are already designed.
  - Runs on a standing cycle or a one-line ask; files land in your own Drive.

### Cons of the ready-made agent

  - Costs $19 once, where DIY prompting is free.
  - The output format is opinionated - you adapt the template rather than rebuild it.
  - It still stops and waits for your approval at decision points; it is not zero-touch.

| -------------------- | ---------------------- | ---------------------------------------------- | ---------------------------------- |
| Time to first result | half a day every month | An afternoon of prompt tuning                  | About 10 minutes, tested setup     |
| Every run after      | Same hours, every time | Re-paste the rules, sheet and context each run | One short ask, or a standing cycle |
| Consistency          | Depends on the day     | Drifts between sessions                        | Same output shape every run        |
| Cost                 | Your hours             | Free, plus your time                           | $19 once, files kept forever       |

The manual way teaches you the job. DIY prompting is fine for a one-off. The agent wins when the job repeats every week.
