Spreadsheet, off-the-shelf dashboard or BI: which to use for media reporting
All three work and all three charge you something different. When a spreadsheet is still right, when BI becomes a trap, and the criterion for deciding.
Also available in: Português · Español
Every agency and every marketing team hits this decision, usually when the spreadsheet starts to hurt. All three options work; they simply charge you different things.
What each one really costs
| visible cost | hidden cost | |
|---|---|---|
| Spreadsheet | zero | 4 to 12 hours a month, silent formula errors |
| Off-the-shelf dashboard | subscription | what it does not cover |
| Your own BI | licence and implementation | ongoing maintenance and dependence on one person |
The hidden cost is what decides, and it is what nobody calculates when choosing.
Spreadsheet
Works when: one account, two or three channels, monthly reporting, and whoever builds it has something else to do with their time — but not much.
Real advantages: total flexibility, zero cost, anyone can edit it, and the client already knows how to open it.
Where it hurts:
Manual exporting eats 4 to 12 hours a month, and those hours appear nowhere in the cost sheet.
Silent errors are the worst part. A formula with the wrong range after someone pastes an extra row produces a plausible, wrong number for months. There is no warning.
And the data does not agree with itself: two people build the same spreadsheet differently and arrive at different numbers for the same month.
When to stop: when you have more than two accounts, or when someone has already spent half a day hunting why two numbers do not reconcile.
Off-the-shelf dashboard
Works when: you need the same questions answered every week, across more than one account, and you do not want to maintain code.
Real advantages: the data arrives on its own, everyone looks at the same source, history is not lost when someone leaves, and the client can have access.
Where it hurts:
It answers what it was designed to answer. The odd question you had today may not fit.
Not every dashboard connects media to the CRM — and without the CRM, you have a pretty dashboard of platform metrics, which is the problem you were trying to solve.
The choice criterion: it is not "does it do everything?", it is "does it answer what I need to answer every week?". A dashboard that shows spend and conversions but not sales does not fix the pain that sent you looking for a dashboard.
Your own BI
Works when: there is data no off-the-shelf tool reaches (ERP, internal systems, specific commission logic), many accounts, and someone responsible for maintaining it.
That third condition is what kills most projects. BI with no owner has a predictable fate: it works for three months, breaks when an API changes, nobody fixes it, everyone goes back to the spreadsheet. The whole investment becomes a loss.
Real advantages: answers any question, integrates any source, and the data stays under your control.
Where it hurts:
Implementation measured in months, not weeks. Eternal maintenance, because APIs change. And dependence on one person: when they leave, the knowledge goes with them.
An honest test before starting: who fixes it when it breaks on a Friday night? If there is no name, do not start.
The criterion, in three questions
1. How many accounts? One, a spreadsheet is fine. Two to ten, an off-the-shelf dashboard. Above that, dashboard or BI depending on question 2.
2. Does the question that matters fit in an off-the-shelf dashboard? If what you need is spend, leads, sales and revenue by campaign and creative, it fits. If you need to cross it with inventory, per-rep commission and margin by SKU, it does not.
3. Is there someone to maintain it? If not, BI is out, regardless of the other two answers.
The most common path
Most people land on an off-the-shelf dashboard and stay. They start with a spreadsheet because it is free, it hurts at the third account, they migrate to a dashboard that joins media and CRM, and only consider BI when data appears that no tool reaches.
The most expensive mistake is jumping straight to BI. Six months of project, a budget spent, and a tool that answers what an off-the-shelf dashboard already answered — plus the maintenance you now carry forever.
The second most expensive mistake is staying on the spreadsheet too long. The monthly hours do not show up in accounting, but they are real, and the silent error is only discovered when someone decides budget based on it.
To sum up
Spreadsheet for one account and patience. Off-the-shelf dashboard for anyone who needs the same answers every week and does not want to maintain code — checking that it joins media with CRM, which is where most of them fail. BI when there is unreachable data and, mandatorily, someone to maintain it.
And count the spreadsheet hours before calling it free.

Frequently asked questions
Is a spreadsheet still fine for paid media reporting?
It is, for one account and a few channels. Its cost is not the licence, it is the monthly hours someone spends building it and the chance of a silent formula error.
When is building your own BI worth it?
When there is data no off-the-shelf tool reaches, many accounts, and someone responsible for maintaining it. Without the third condition, the project dies within six months.
Is an off-the-shelf dashboard too limited?
It is limited by definition, and that is the point. The right question is whether what it covers is what you need to answer every week, not whether it does everything.
What is the hidden cost of each option?
Spreadsheet: hours and silent errors. Off-the-shelf dashboard: the subscription and what it does not cover. BI: ongoing maintenance and dependence on one person.
